PART I

ITEM 1. BUSINESS (IN THOUSANDS, EXCEPT PERCENTAGE AND EMPLOYEE DATA)

AAR CORP. and its subsidiaries are referred to herein collectively as
"AAR" or the "Company," unless the context indicates otherwise. The Company
was organized in 1955 as the successor to a business founded in 1951 and was
reincorporated in Delaware in 1966. The Company is a worldwide leader in
supplying aftermarket products and services to the global aviation/aerospace
industry.

Certain of the Company's aviation-related activities and products are
subject to licensing, certification and other requirements imposed by the
Federal Aviation Administration (FAA) and other regulatory agencies, both
domestic and foreign. The Company believes that it has all licenses and
certifications that are material to the conduct of its business.

The Company reports its activities in one business segment: Aviation
Services. Three classes of similar products and services are included within
this segment: (i) Aircraft and Engines, (ii) Airframe and Accessories and
(iii) Manufacturing.

The Company's Aircraft and Engines activities include (i) the purchase,
sale, and lease of new and used commercial jet aircraft, (ii) the purchase,
sale and lease of a wide variety of new, overhauled and repaired engines and
engine products for the aviation aftermarket, including a broad range of
spare engines and engine parts and other engine components and accessories,
and (iii) the overhaul, repair and exchange of a wide range of engine parts
and components and other engine support services for its commercial and
military customers. The Company also provides customized inventory supply and
management programs for engine parts and components in support of customer
maintenance activities. The Company has two FAA licensed repair stations in
the U.S. to perform engine component overhaul services which cover a broad
range of internal engine parts and components. The Company also provides
turbine engine overhaul and parts supply services to industrial gas and steam
turbine operators. The Company's primary sources of aviation products for its
Aircraft and Engine activities are domestic and foreign airlines, independent
aviation service companies, aircraft leasing companies and original equipment
manufacturers.

The Company's Airframe and Accessories activities consist of (i) the
purchase, sale and lease of new, overhauled and repaired airframe parts and
accessories for the aviation aftermarket, and (ii) a wide variety of airframe
and accessory parts and components overhaul, as well as repair and exchange
services for its commercial, military and general aviation customers. The
Company also provides customized inventory supply and management programs for
certain airframe parts and components in support of customer maintenance
activities. The Company's primary sources of airframe parts for its Airframe
and Accessories activities are domestic and foreign airlines, independent
aviation service companies and aircraft leasing companies. The Company is
also an authorized distributor for more than 200 leading aviation/aerospace
product manufacturers.

The Company's Airframe and Accessories overhaul and repair capabilities
include most commercial aircraft landing gear, a wide variety of avionics,
instruments, electrical, electronic, fuel, hydraulic and pneumatic components
and a broad range of internal airframe components. AAR also operates an
aircraft maintenance facility providing maintenance, modification, special
equipment installation, painting services and aircraft terminal services for
various models of commercial, military, regional, business and general
aviation aircraft. During fiscal 1999, the Company purchased the assets of
Tempco Hydraulics, Inc., a regional aircraft landing gear repair and overhaul
business. AAR's overhaul and repair of parts and components also support the
sale, lease and inventory management activities of the Company. AAR has eight
FAA-licensed repair stations in the U.S. and two in Europe to perform
airframe/component overhaul services.

2
The Company's Manufacturing activities include (i) the design,
manufacture and installation of in-plane cargo loading and handling systems
for commercial and military aircraft and helicopters, (ii) the design and
manufacture of advanced composite materials for commercial, business and
military aircraft, (iii) the manufacture and repair of a wide array of
containers, pallets and shelters in support of military and humanitarian
rapid deployment activities, (iv) the design and manufacture of a line of
specialized protective transport cases that are used to transport sensitive
and calibrated tools and instruments, and a variety of vacuum storage
containers that protect machinery and equipment during long-term storage.
During fiscal 1999, the Company divested substantially all of its assets and
related liabilities of its floor maintenance products manufacturing
subsidiary.

The Company furnishes aviation products and services primarily through
its own employees. The principal customers for the Company's products and
services are domestic and foreign commercial airlines, regional/commuter
airlines, business aircraft operators, aviation original equipment
manufacturers, aircraft leasing companies, domestic and foreign military
organizations and independent aviation support companies. Sales of aviation
products and services to commercial airlines are generally affected by such
factors as the number, type and average age of aircraft in service, the
levels of aircraft utilization (e.g., frequency of schedules), the number of
airline operators and the level of sales of new and used aircraft.

The Company is a leading independent supplier of aviation products and
services to the highly competitive worldwide aviation/aerospace aftermarket.
Competition is based on quality, ability to provide a broad range of products
and services, speed of delivery and price. Competitors in the parts supply
business include the original equipment manufacturers, commercial airlines,
and other independent suppliers of parts and services. In certain of its
leasing and commercial jet aircraft trading activities, the Company faces
competition from financial institutions, syndicators, commercial and
specialized leasing companies and other entities that provide financing. AAR
also competes with various repair and overhaul organizations, which include
the service arms of original equipment manufacturers, the maintenance
departments or divisions of large commercial airlines (some of which also
offer maintenance services to third parties) and independent organizations.
AAR's pallet, container and shelter manufacturing activities compete with
several modest-sized private companies, and its cargo systems competitors
include a number of divisions of large corporations. Although certain of the
Company's competitors have substantially greater financial and other
resources than the Company, the Company believes that it has maintained a
satisfactory competitive position through its responsiveness to customer
needs, its attention to quality and its unique combination of trading
expertise, technical capabilities and financial strength.

At May 31, 1999, backlog believed to be firm was approximately $83,600
compared to $107,400 at May 31, 1998. An additional $8,100 of unfunded
government options on awarded contracts also existed at May 31, 1999. It is
expected that approximately $82,100 of the May 31, 1999 backlog will be
shipped in fiscal 2000.

3
Sales to the U.S. Government, its agencies and its contractors were
approximately $98,954 (10.8 % of total net sales), $83,114 (10.6% of total
net sales) and $82,125 (13.9% of total net sales) in fiscal years 1999, 1998
and 1997, respectively. Because such sales are subject to competitive bidding
and government funding, no assurance can be given that such sales will
continue at levels previously experienced. The majority of the Company's
government contracts are for aviation products and services used for ongoing
routine military logistic support activities; unlike weapons systems and
other high-technology military requirements, these products and services are
less likely to be affected by reductions in defense spending. The Company's
contracts with the U.S. Government and its agencies are typically firm
agreements to provide aviation products and services at a fixed price and
have a term of one year or less, frequently subject to extension for one or
more additional periods of one year at the option of the government agency.
Although the Company's government contracts are subject to termination at the
election of the government, in the event of such a termination the Company
would be entitled to recover from the government all allowable costs incurred
by the Company through the date of termination.

At May 31, 1999, the Company employed approximately 2,900 persons
worldwide.

For additional information concerning the Company's business segment
activities, including classes of similar products and services, see Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." For information concerning export sales, see "Business Segment
Information" in Note 11 of Notes to Consolidated Financial Statements.

ITEM 2. PROPERTIES

The Company's principal aircraft and engine sales and leasing
activities as well as engine and airframe components and aftermarket parts
distribution activities are conducted from one building, which is owned by
the Company, in Wood Dale, Illinois. In addition to warehouse space, the
facility includes executive and sales offices. The Company also owns and
operates one building in Elk Grove Village, Illinois for the purpose of the
distribution of new aviation parts. Warehouse facilities are leased in
Windsor Locks, Connecticut; Hamburg and Hannover, Germany; Nantgarw, Wales;
and Brussels, Belgium for the purpose of aviation parts distribution.

Aviation overhaul facilities are located in The Netherlands near
Schiphol International Airport in a building owned by the Company; Garden
City, New York in a building owned by the Company; Frankfort, New York
(subject to an industrial revenue bond to the Company until 2001, at which
time the Company expects to purchase the facility for nominal consideration);
Windsor, Connecticut in a building owned by the Company; Miami, Florida in
leased facilities; London, England in leased facilities, and Oklahoma City,
Oklahoma in facilities leased from airport authorities. The Company's
experience indicates that lease renewal is available on reasonable terms
consistent with its business needs.

The Company's principal manufacturing activities are conducted at owned
facilities in Clearwater, Florida (subject to an industrial revenue bond);
Port Jervis, New York; and Cadillac and Livonia, Michigan.

The Company believes that its owned and lease facilities are suitable
and adequate for its existing business.

ITEM 3. LEGAL PROCEEDINGS

The Company is not a party to any material, pending legal proceedings
(including any governmental or environmental proceedings) other than routine
litigation incidental to its existing business.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted to a vote of security holders during the fourth
quarter of the fiscal year covered by this report.

Executive Officer since 1996. Previously, he was Chief Operating Officer from
1989 to 1996 and a Vice President of the Company from 1988 to 1989. Mr.
Storch joined the Company in 1979 and was President of a major subsidiary
from 1984 to 1988. Mr. Storch has been a director of the Company since 1989.
Mr. Storch is Mr. Eichner's son-in-law.

MR. EICHNER, the founder of the Company, has been Chairman of the Board

At the July 1999 Board Meeting, the Board of Directors acknowledged
the extraordinary contributions to AAR of Ira A. Eichner as he relinquished
his role as an executive officer. As founder of the Company, Mr. Eichner's
vision, foresight and leadership has resulted in growing AAR into a billion
dollar New York Stock Exchange public company, recognized as the pre-eminent
product and services provider in the aviation industry. His energetic
dedication to the Company's success and to ensuring shareholder value has
been unparalleled for more than 48 years. He brought diversity to the
Company's capabilities and customer base through a series of strategic
acquisitions, creating balance and synergies between its trading, overhaul
and manufacturing businesses. He also set a standard of integrity, instilling
it into the Company's culture for all employees to emulate.

In addition to leading AAR through good times and more difficult
periods, achieving profitability every year since the Company's inception,
Mr. Eichner emphasized the importance to the Company's future of prudent
fiscal management and a strong balance sheet. He built an outstanding
management team, paying special attention to successful management planning
in order to provide for the Company's ongoing growth. The Board of Directors
feel most fortunate that, as a continuing director and nonexecutive Chairman
of the Board, Ira Eichner will give his guidance and counsel to the Company's
management, sharing his wealth of experience.

THREE-YEAR NET SALES SUMMARY

Over the last three fiscal years, consolidated net sales increased as
the Company successfully pursued opportunities in the aviation/aerospace
market. The Company has broadened the range of products sold, created and
maintained long-term strategic supply relationships with customers, and
established industry-leading capabilities in inventory asset management
programs. The Company has developed a customized portfolio of value-added
products and services, such as Internet-based electronic commerce tools, to
take advantage of changing market dynamics. Net sales growth during the
three-year period also benefited from acquisitions of new-parts distribution
and aircraft composites manufacturing businesses, as well as an overall
growth in customer base. These factors, coupled with a sustained period of
economic growth and profitability in the worldwide aviation/aerospace market,
resulted in a net sales increase in all three of the Company's classes of
similar products and services over the last three fiscal years.

The Company believes that its established global market position, its
ability to respond to changes in the industry, including technological
changes, and its diverse customer base, position the Company to take
advantage of future opportunities in the aviation/aerospace market.*







* THIS SECTION CONTAINS FORWARD-LOOKING STATEMENTS WHICH ARE IDENTIFIED WITH AN
ASTERISK (*). PLEASE SEE COMMENTS ON FORWARD-LOOKING STATEMENT RISK FACTORS
IN THE "FORWARD-LOOKING STATEMENTS" SECTION ON PAGE 12 .

8
FISCAL 1999 COMPARED WITH FISCAL 1998

Consolidated net sales for fiscal 1999 increased 17.4% to $918.0
million from $782.1 million in fiscal 1998. This increase was attributable to
continued strong demand for the Company's broad range of products and
services and, among other things, full-year sales from businesses acquired in
fiscal 1998. Aircraft and Engines sales increased $76,897 or 22.7% resulting
from higher sales of engine parts, driven primarily from strength in
inventory management programs, and increased aircraft sales and leasing
revenues. These increases were partially offset by the impact of certain
engine parts sales which were recorded by Turbine Engine Asset Management
L.L.C. (an unconsolidated joint venture company) during fiscal 1999, but were
recorded by Aircraft and Engines during the first half of fiscal 1998.
Airframe and Accessories sales increased $42,976 or 12.9%, driven primarily
by the impact of full-year sales from the new-parts distribution companies
acquired during fiscal 1998, as well as increased demand for aircraft
maintenance and landing gear overhaul repair capabilities. Manufacturing
sales increased $16,040 or 14.6% due to increased sales of products
supporting the U.S.Government's rapid deployment program, the inclusion of
full-year sales from AAR Composites (acquired in fiscal 1998) and higher
sales of cargo handling systems. These gains were partially offset by the
unfavorable impact of the divestiture of the Company's floor maintenance
products manufacturing subsidiary in November 1998.

Consolidated gross profit increased $24,853 or 16.7% due to increased
consolidated net sales. The fiscal 1999 consolidated gross profit margin of
18.9% is slightly less than the consolidated gross profit margin of 19.0% of
the prior year. Consolidated operating income increased $12,665 or 19.6% over
the prior year on the strength of increased sales, partially offset by
increased selling, general and administrative expenses. Selling, general and
administrative expenses were lower as a percentage of consolidated net sales;
however, total expenses increased due to the impact from companies acquired
during fiscal 1998, as well as increased marketing support and information
technology costs, which include Year 2000 compliance costs. Interest expense
increased $4,073 or 28.1% over the prior year primarily due to the full-year
effect of the $60 million of unsecured 6.875% Notes issued in December 1997.

Consolidated net income increased $6,014 or 16.9% over the prior year as
a result of the above-noted factors.

9
FISCAL 1998 COMPARED WITH FISCAL 1997

Consolidated net sales increased $192,795 or 32.7% over the prior
fiscal year, reflecting strong demand for the Company's broad range of
products and services and the effect of acquisitions during fiscal 1998.
Acquisitions, net of prior year dispositions, contributed $77,234 to the
sales increase over the prior year. Aircraft and Engines sales increased
$76,225 or 29.0%, resulting from higher sales in its engine and engine parts
businesses, as well as increased aircraft sales. Airframe and Accessories
sales increased $111,850 or 50.5%, driven primarily by sales from the
new-parts distribution companies, which were acquired in fiscal 1998, and
increased demand for the Company's aircraft maintenance and aircraft
component overhaul and repair capabilities. Sales in Manufacturing increased
$4,720 or 4.5%, reflecting increased cargo loading and handling system sales
and the inclusion of sales from ATR (AAR Composites), which was acquired in
October 1997, partially offset by lower sales from products supporting the
U.S. Government's rapid deployment program.

Consolidated gross profit increased $39,865 or 36.7%, due to increased
consolidated net sales and an increase in the consolidated gross profit
margin to 19.0% from 18.4% in the prior year. The increase in the
consolidated gross profit margin during fiscal 1998 reflected the favorable
mix of inventories sold and improved margins in certain manufactured products.

Consolidated operating income increased $21,826 or 50.9% over the prior
fiscal year as a result of the increase in net sales and the higher gross
profit margin, partially offset by increased selling, general and
administrative expenses. Selling, general and administrative expenses were
lower as a percentage of consolidated net sales; however, total expenses
increased principally due to the inclusion of recently acquired companies and
increased personnel costs. Interest expense increased $3,708 or 34.4% over
the prior year, principally due to the impact of the Company's sale of $60
million of unsecured 6.875% Notes in December 1997.

Consolidated net income increased $12,632 or 54.9% over the prior year
as a result of the factors previously discussed.

FISCAL 1997 COMPARED WITH FISCAL 1996

The Company's operating results showed improvement over the prior
fiscal year as it experienced higher demand for its products and services in
a strong aviation/aerospace market. Consolidated net sales increased $84,338
or 16.7% over the prior fiscal year reflecting higher sales in the Company's
Aircraft and Engines and Airframe and Accessories activities. Consolidated
operating income increased $10,448 or 32.2% over the prior year due to
increased consolidated net sales and a higher consolidated gross profit
margin, partially offset by higher selling, general and administrative costs.
Net income increased $7,013 or 43.8%, due to increased consolidated net sales
and gross profit margin.

Aircraft and Engines sales increased $80,845 or 44.4% over the prior
year due to growth in sales of engine parts and engine and aircraft sales and
leasing products. Increased volume through the Company's long-term inventory
management programs contributed to the sales increase in engine parts.
Airframe and Accessories sales increased $18,550 or 9.1%, reflecting
increased demand for certain aircraft and aircraft component repair and
maintenance services and higher airframe parts sales. Sales in Manufacturing
declined $15,057 or 12.6%, resulting from lower demand for products
supporting the U.S. Government's rapid deployment program.

Consolidated gross profit increased $17,776 or 19.6%, due to increased
consolidated net sales and an increase in the consolidated gross profit
margin to 18.4% from 18.0% in the prior year. The increase in the
consolidated gross profit margin during fiscal 1997 was attributable to the
favorable mix of products and services sold through Aircraft and Engines and
Airframe and Accessories activities, partially offset by lower margins on
certain manufactured products due to lower sales volume.

10
Consolidated operating income increased $10,448 or 32.2% over the prior
year as a result of the increase in consolidated net sales and the higher
consolidated gross profit margin, partially offset by higher selling, general
and administrative costs. The increase in selling, general and administrative
costs was driven by increased personnel and marketing support costs.

Consolidated net income increased $7,013 or 43.8% over the prior year
as a result of the factors discussed above.

11
LIQUIDITY AND CAPITAL RESOURCES


At May 31, 1999, the Company's liquidity and capital resources included
cash and cash equivalents of $8,250 and working capital of $334,600. At May
31, 1999, the Company's long-term debt-to-capitalization ratio was 35.7%,
compared to 37.1% at May 31, 1998. The Company continues to maintain its
external sources of financing with $178,800 of unused available bank lines
and a shelf registration statement on file with the Securities and Exchange
Commission under which up to $200 million of common stock, preferred stock or
medium- or long-term debt securities may be issued or sold subject to market
conditions.

During fiscal 1999, the Company generated $28,525 of cash from
operations compared to $22,823 and $9,531 during fiscal 1998 and 1997,
respectively. This was principally attributable to increased net income and
improved working capital management.

During fiscal 1999, the Company's investing activities used $22,893 of
cash primarily composed of $36,131 of property, plant and equipment
expenditures reflecting the Company's continued investment in new information
technology systems and facility expansions; a $6,000 payment made for the
Tempco acquisition, which was acquired in October 1998; and a final payment
of $9,175 for the acquisition of AVSCO, which was acquired in December 1997,
offset by proceeds from the sale of equipment on long-term lease and cash
received from the divestiture of the Company's floor maintenance products
manufacturing subsidiary of $11,685.

During fiscal 1999, the Company's financing activities used $14,602 of
cash, reflecting primarily the payment of cash dividends of $9,375 and the
purchase of $7,558 of the Company's stock, offset by proceeds of an
industrial revenue bond of $2,300.

The Company believes that its cash and cash equivalents and available
sources of capital will continue to provide the Company with the ability to
meet its ongoing working capital requirements, make anticipated capital
expenditures, meet contractual commitments and pay dividends.*

YEAR 2000

During fiscal 1997, the Company initiated a comprehensive information
technology systems review which resulted in a formal plan to replace and
enhance certain of the Company's business application systems to meet current
operational requirements and provide for future expansion. These replacement
systems are Year 2000 compliant and include new information technology
systems in the Company's new-parts distribution business, all of the
Company's manufacturing facilities and three of the Company's overhaul
facilities.

During the third quarter of fiscal 1999, the Company successfully
completed the implementation of the replacement systems at its manufacturing
facilities. During March 1999, the Company successfully completed the
implementation of the replacement system in its new-parts distribution
business. The capital outlay associated with the successful implementation of
the replacement systems in the manufacturing and new-parts distribution
businesses was $8,700, of which $7,600 was paid during the twelve-month
period ended May 31, 1999.

The Company has expanded and modified its plans to replace the existing
systems at its overhaul facilities to include, among other things, purchasing
new hardware, upgrading the main existing operating system and converting the
existing business application to ensure Year 2000 compliance. The Company
believes that the cost of the new hardware and the cost to upgrade the
existing operating system to provide for Year 2000 compliance for the
overhaul businesses' current systems will be approximately $1,000.*
Additional enhancements, which include the implementation of the new systems,
may continue into the Year 2000, although the Company anticipates that the
business applications supporting the three overhaul facilities will be Year
2000 compliant by October 1999.*

In addition to the above, the Company has conducted an extensive Year
2000 compliance review of its internal systems which are not being replaced.
Based on this study and program testing, the Company believes that the
business applications supporting the Company's trading businesses and certain
other overhaul businesses are Year 2000 compliant.* In addition, the Company
believes that its existing major financial applications are Year 2000
compliant, although the Company is in the process of upgrading its major
financial applications to the most recent version.*

In addition to the cost of the business application systems being
implemented or enhanced to meet operational requirements, the Company expects
to incur other Year 2000 compliance costs unrelated to the replacement
systems referenced above. The Company has numerous local-area networks,
wide-area networks, servers, voice mail systems and other technical support
systems (the "sub-systems"). The Company has completed an inventory of the
sub-systems, as well as the compliance status of the sub-systems, and
believes that approximately 95% of the sub-systems are Year 2000 compliant.*
The Company expects the remaining sub-systems will be Year 2000 compliant by
September 30, 1999 at a cost of less than $100.*

- -----------------

* See "Forward Looking Statements" section of this item.

13
YEAR 2000 (CONTINUED)

As part of its continuing review, the Company has communicated with its
material vendors, customers and suppliers regarding their Year 2000
compliance. While the Company is aggressively addressing the Year 2000 issue
internally, the compliance status of third parties with which the Company has
material relationships is presently unknown and the failure of third parties
to be compliant could potentially have an adverse effect on the Company's
operations.* The Company believes that the Year 2000 compliance failure of a
significant third-party supplier or customer is the most reasonably likely
worst case scenario for a Year 2000 failure.* As compliance risks become
known for significant third parties, contingency plans will be developed
accordingly.

FORWARD-LOOKING STATEMENTS

Management's Discussion and Analysis of Financial Condition and Results
of Operations contains certain statements relating to future results, which
are forward-looking statements as that term is defined in the Private
Securities Litigation Reform Act of 1995 and are identified by an
asterisk(*). These forward-looking statements are based on beliefs of Company
management, as well as assumptions and estimates based on information
currently available to the Company, and are subject to certain risks and
uncertainties that could cause actual results to differ materially from
historical results or those anticipated, depending on a variety of factors,
including: integration of acquisitions; marketplace competition;
implementation of Year 2000 compliant information technology systems and
system enhancements; unidentified Year 2000 problems; failure of a
third-party supplier, service provider or customer to be Year 2000 compliant;
economic and aviation/aerospace market stability and Company profitability.
Should one or more of these risks or uncertainties materialize adversely, or
should underlying assumptions or estimates prove incorrect, actual results
may vary materially from those described.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's exposure to market risk is limited to fluctuating
interest rates under its unsecured bank credit agreements, and foreign
exchange rates. During fiscal 1999 and 1998, the Company did not utilize
derivative financial instruments to offset these risks.

At May 31, 1999, $65,300 was available under credit lines with domestic
banks, $110,000 was available under revolving credit and term loan agreements
with domestic banks, and $3,500 was available under credit agreements with
foreign banks (credit facilities). Interest on amounts borrowed under the
credit facilities is based on an overnight bid rate. While the Company
utilized these credit facilities during fiscal 1999, as of May 31, 1999,
there was no outstanding balance. A hypothetical 10 percent increase to the
average interest rate under the credit facilities would not have had a
material impact on the results of operations for the Company during fiscal
1999.

Revenues and expenses of the Company's foreign operations in The
Netherlands are translated at average exchange rates during the year and
balance sheet accounts are translated at year-end exchange rates. Balance
sheet translation adjustments are excluded from the results of operations and
are recorded in stockholders' equity as a component of accumulated other
comprehensive income (loss). A hypothetical 10 percent devaluation of foreign
currencies against the U.S. dollar would not have a material impact on the
financial position or results of operations of the Company.

significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of AAR CORP.
and subsidiaries as of May 31, 1999 and 1998, and the results of their

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

AAR CORP. (the Company) supplies a variety of products and services to
the worldwide aviation/aerospace industry. Products and services are sold
primarily to commercial, domestic and foreign airlines; business aircraft
operators; aviation original equipment manufacturers; aircraft leasing
companies; domestic and foreign military agencies and independent aviation
support companies.

PRINCIPLES OF CONSOLIDATION

The accompanying consolidated financial statements include the accounts
of the Company and its subsidiaries after elimination of intercompany
accounts and transactions.

The Company conducts portions of its business through joint venture
investments accounted for under the equity method. These equity affiliates
are primarily engaged in the distribution of certain engine parts and
aircraft rotable spares to worldwide aviation customers. The financial
position and results of operations for the joint ventures during fiscal 1999
and 1998 are not material.

REVENUE RECOGNITION

Sales and related cost of sales are recognized primarily upon shipment
of products and performance of services. Lease revenue is recognized as
earned.

NEW ACCOUNTING STANDARDS

FASB Statement of Financial Accounting Standards (SFAS) No. 130
"Reporting Comprehensive Income" is effective for fiscal years beginning
after December 15, 1997. SFAS No. 130 establishes standards for the reporting
and display of comprehensive income and its components in a full set of
general-purpose financial statements. The Company adopted the provisions of
SFAS No. 130 in fiscal 1999.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

NEW ACCOUNTING STANDARDS (CONTINUED)

SFAS No. 131 "Disclosures about Segments of an Enterprise and Related
Information" is effective for fiscal years beginning after December 15, 1997.
SFAS No. 131 establishes standards for public companies to report financial
and descriptive information about reportable operating segments in annual
financial statements and interim financial reports issued to stockholders.
The Company operates in one segment: Aviation Services. The Company's
determination of its reportable segment is based on the commonalities among
the products and services within its Aviation Services segment, and is
consistent with the manner in which the Company's management reviews and
evaluates operating performance.

SFAS No. 132 "Employers' Disclosures about Pensions and Other
Postretirement Benefits" is effective for fiscal years beginning after
December 15, 1997. SFAS No. 132 revises disclosures for pension and other
postretirement plans, but does not change the measurement or recognition of
liabilities or expense related to pension or other postretirement plans. The
Company adopted the provisions of SFAS No. 132 in fiscal 1999.

In March 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accounts (ACSEC) issued Statement of
Position (SOP) 98-1, "Accounting for the Costs of Computer Software Developed
or Obtained for Internal Use." In April 1998, the ACSEC issued SOP 98-5,
"Reporting on the Costs of Start-Up Activities." The adoption of SOP 98-1 and
SOP 98-5 did not have a material effect on the Company's financial position
or results of operations during fiscal 1999.

SFAS No. 133 "Accounting for Derivative Instruments and Hedging
Activities" is effective for fiscal years beginning after June 15, 2000. SFAS
No. 133 establishes accounting and reporting standards for derivative
instruments and for certain hedging activities. It requires that an entity
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. The Company
is evaluating the new Statement's provisions to determine the impact, if any,
and will adopt SFAS No. 133 in its first quarter of fiscal 2002.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with maturities of
three months or less to be cash equivalents. At May 31, 1999 and 1998, cash
equivalents of approximately $116 and $177, respectively, represent
investments in funds holding high-quality commercial paper, Eurodollars and
U.S. Government agency-issued securities. The carrying amount of cash
equivalents approximates fair value at May 31, 1999 and 1998, respectively.

TRANSFER OF FINANCIAL ASSETS

During fiscal 1998, the Company adopted SFAS No. 125, "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities", which requires the Company to recognize the financial and
servicing assets it controls and the liabilities it has incurred, and to
derecognize financial assets when control has been surrendered.

During fiscal 1999, the Company amended its agreement to sell, on a
revolving basis, an interest in a defined pool of trade accounts receivable.
Among the terms amended, the amount of accounts receivable which could be
sold under the program was reduced from $50 million to $35 million. The
Company, as agent for the purchaser of the accounts receivable, retains
collection and administrative responsibilities for the participating
interests of accounts receivable. Accounts receivable sold under this
arrangement were $25,300 and $0 at May 31, 1999 and 1998, respectively.

FOREIGN CURRENCY

Gains and losses on foreign currency translation and foreign exchange
contracts are determined in accordance with the method of accounting
prescribed by SFAS No. 52. All balance sheet accounts of foreign and certain
domestic subsidiaries transacting business in currencies other than the
Company's functional currency are translated at year-end or historical
exchange rates. Revenues and expenses are translated at average exchange
rates during the year. Translation adjustments are excluded from the results
of operations and are recorded in Stockholders' equity as a component of
accumulated other comprehensive income (loss).

FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF MARKET OR CREDIT RISK

Financial instruments that potentially subject the Company to
concentrations of market or credit risk consist principally of trade
receivables. While the Company's trade receivables are diverse based on the
number of entities and geographic regions, the majority are in the
aviation/aerospace industry. The Company performs evaluations of customers'
financial condition prior to extending credit privileges and performs ongoing
credit evaluations of payment experience, current financial condition and
risk analysis. The Company typically requires collateral in the form of
security interest in assets, letters of credit, and/or obligation guarantees
from financial institutions, or sells its receivables, usually on a
nonrecourse basis, for transactions other than normal trade terms.

SFAS No. 107 "Disclosures about Fair Value of Financial Instruments"
requires disclosure of the fair value of certain financial instruments. Cash
and cash equivalents, accounts receivable, short-term borrowings, accounts
payable and accrued liabilities are reflected in the consolidated financial
statements at fair value because of the short-term maturity of these
instruments. The carrying value of noncurrent notes receivable and long-term
debt bearing a variable interest rate approximates fair market value.

Fair value estimates are made at a specific point in time based on
relevant market information about the financial instrument. These estimates
are subjective in nature and involve uncertainties and matters of significant
judgment and therefore cannot be determined with precision. Changes in
assumptions could significantly affect the estimates.

INVENTORIES

Inventories are priced at the lower of cost or market. Cost is
determined by either the specific identification, average cost or first-in,
first-out method.

The following is a summary of inventories:

EQUIPMENT UNDER OPERATING LEASES

Lease revenue is recognized as earned. The cost of the asset under
lease is original purchase price plus overhaul costs. Depreciation is
computed on a straight-line method over the estimated service life of the
equipment and maintenance costs are expensed as incurred. The balance sheet
classification is based on the lease term with fixed-term leases less than
twelve months classified as short term and all others classified as long term.

Equipment on short-term lease consists of aircraft engines and parts on
or available for lease to satisfy customers' immediate short-term
requirements. The leases are renewable with fixed terms, which generally vary
from one to twelve months. Equipment on long-term lease consists of aircraft
and engines on lease to customers with a lease term greater than twelve
months.

PROPERTY, PLANT AND EQUIPMENT

Depreciation is computed on the straight-line method over useful lives
of 10-40 years for buildings and improvements and 3-10 years for equipment,
furniture and fixtures and capitalized software. Leasehold improvements are
amortized over the shorter of the estimated useful life or the term of the
applicable lease.

Repairs and maintenance expenditures are expensed as incurred. Upon
sale or disposal, cost and accumulated depreciation are removed from the
accounts and related gains and losses are included in results of operations.

LEVERAGED LEASES

The Company acts as an equity participant in leveraged lease
transactions. The equipment cost in excess of equity contribution is financed
by third parties in the form of secured debt. Under the lease agreements, the
third parties have no recourse against the Company for nonpayment of the
obligations. The third-party debt is collateralized by the lessees' rental
obligations and the leased equipment.

The Company has ownership rights to the leased assets and is entitled
to the investment tax credits and benefits of tax deductions for depreciation
on the leased assets and for interest on the secured debt financing.

COST IN EXCESS OF UNDERLYING NET ASSETS OF ACQUIRED COMPANIES

The cost in excess of underlying net assets of acquired companies is
being amortized over a period of forty years. The increase in cost in excess
of underlying net assets of acquired companies at May 31, 1999 is
attributable to the Company's acquisition of Tempco during fiscal 1999, as
well as final purchase price adjustments related to acquisitions made during
fiscal 1998. Amortization expense was $802, $565 and $223 in fiscal 1999,
1998 and 1997, respectively. Accumulated amortization is $4,975 and $4,173 at
May 31, 1999 and 1998, respectively. The Company evaluates the existence of
impairment on the basis of whether the cost in excess of underlying net
assets of acquired companies is fully recoverable from projected,
undiscounted net cash flows.

domestic banks, $110,000 was available under revolving credit and term loan
agreements with domestic banks and $3,500 was available under credit
agreements with foreign banks. All domestic and foreign credit lines were
unused at May 31, 1999. There are no compensating balance requirements in
connection with domestic or foreign lines of credit. Borrowings under
domestic bank lines bear interest at or below the corporate base rate.

The Company may borrow a maximum of $110,000 (available through
February 9, 2002) under revolving credit and term loan agreements with domestic
banks. Revolving credit borrowings may, at the Company's option, be converted to
term loans payable in equal quarterly installments over five years. Interest
is based on corporate base rate or quoted Eurodollar or multicurrency rates
during the revolving credit period and 1/2% over corporate base rate or
quoted Eurodollar rate thereafter. There were no borrowings under these
agreements outstanding at May 31, 1999. There are no compensating balance
requirements on any of the committed lines, but the Company is required to
pay a commitment fee. There are no restrictions on the withdrawal or use of
these funds.

The Company is subject to a number of covenants under the revolving
credit and term loan agreements, including restrictions which relate to the
payment of cash dividends, maintenance of minimum net working capital and
tangible net worth levels, sales of assets, additional financing, purchase of
the Company's shares and other matters. The Company is in compliance with all
restrictive financial provisions of the agreements. At May 31, 1999,
unrestricted consolidated retained earnings available for payment of
dividends and purchase of the Company's shares was approximately $18,482.
Effective June 1, 1999, unrestricted consolidated retained earnings increased
to $39,318 due to inclusion of 50% of the consolidated net income of the
Company for fiscal 1999. The aggregate amount of long-term debt maturing
during each of the next five fiscal years is $521 in 2000, $524 in 2001,
$65,499 in 2002, $475 in 2003 and $51,479 in 2004. The Company's long-term
debt was estimated to have a fair value of approximately $185,639 at May 31,
1999 and was based on estimates using discounted future cash flows at an
assumed rate for borrowings currently prevailing in the marketplace for
similar instruments.

3. INCOME TAXES -- (CONTINUED)

The Company has determined that the realization of deferred tax assets
is more likely than not, and that a valuation allowance is not required based
upon the Company's history of prior operating earnings, its expectations for
continued future earnings and the scheduled reversal of deferred tax
liabilities, primarily related to leveraged leases, which exceed the amount
of the deferred tax assets.

The provision for income taxes differs from the amount computed by
applying the U.S. Federal statutory income tax rate of 35% for fiscal 1999,
1998 and 1997, for the following reasons:

4. COMMON STOCK AND STOCK OPTION PLANS

The Company has established stock option plans for officers and key
employees of the Company. Stock option awards typically expire ten years from
the date of grant or earlier upon termination of employment, become
excercisable in five equal increments on successive grant anniversary dates
at the New York Stock Exchange closing stock price on the date of grant and
are accompanied by reload features and, for certain individuals, stock rights
exercisable in the event of a change in control of the Company.

The Company accounts for these plans under APB No. 25, under which no
compensation cost has been recognized. Proforma information regarding net
income and earnings per share is required by SFAS No. 123 and has been
determined as if the Company had accounted for its employee stock options
under the fair value method of SFAS No. 123. The fair value of each option
grant, including reloads, is estimated on the date of grant using the
Black-Scholes option-pricing model with the following weighted average
assumptions:

Had compensation cost for stock options awarded under the plans been
determined in accordance with SFAS No. 123, the Company's net income and
earnings per share would have been changed to the following proforma amounts:

The AAR CORP. Stock Benefit Plan also provides for the grant of
restricted stock awards. Restrictions are released at the end of applicable
restricted periods. The number of shares and the restricted period, which
varies from two to ten years, are determined by the Compensation Committee of
the Board of Directors. The market value of the award on the date of grant is
recorded as a deferred expense, Common stock and Capital surplus. The
deferred expense is included in results of operations over the vesting
period. The expense relating to outstanding restricted stock awards was
$1,667, $1,400 and $1,054 in fiscal 1999, 1998 and 1997, respectively.

4. COMMON STOCK AND STOCK OPTION PLANS -- (CONTINUED)

The AAR CORP. Employee Stock Purchase Plan is open to employees of the
Company (other than officers, directors or participants in other stock option
plans of the Company) and permits employees to purchase common stock in
periodic offerings by payroll deductions.

The numbers of options and awards outstanding and available for grant
or issuance for each of the Company's stock plans are as follows:

Stock Benefit Plan (officers, directors and key

Employee Stock Purchase Plan........................................ 67 115 182

</TABLE>

Pursuant to a shareholder rights plan adopted in 1997, each outstanding
share of the Company's common stock carries with it a Right to purchase one
and one half additional shares at a price of $83.33 per share (adjusted to
reflect the February 23, 1998 stock split and subject to further antidilution
adjustments). The Rights become exercisable (and separate from the shares)
when certain specified events occur, including the acquisition of 15% or more
of the common stock by a person or group (an "Acquiring Person") or the
commencement of a tender or exchange offer for 15% or more of the common
stock.

In the event that an Acquiring Person acquires 15% or more of the
common stock, or if the Company is the surviving corporation in a merger
involving an Acquiring Person or if the Acquiring Person engages in certain
types of self-dealing transactions, each Right entitles the holder to
purchase for $83.33 per share, (or the then-current exercise price) shares of
the Company's common stock having a market value of $166.66 (or two times the
exercise price), subject to certain exceptions. Similarly, if the Company is
acquired in a merger or other business combination or 50% or more of its
assets or earning power is sold, each Right entitles the holder to purchase
at the then-current exercise price that number of shares of common stock of
the surviving corporation having a market value of two times the exercise
price. The Rights, which do not entitle the holder thereof to vote or to
receive dividends, replace the common stock purchase rights which were
initially distributed to the Company's shareholders in 1987 and which expired
by their own terms on August 6, 1997. The Rights will expire on August 6,
2007, and may be redeemed by the Company for $.01 per Right under certain
circumstances.

On September 21, 1990, the Board of Directors authorized the Company to
purchase up to 1,500 shares (adjusted for the three-for-two stock split) of
the Company's common stock on the open market or through privately negotiated
transactions. As of May 31, 1999, the Company had purchased 1,083 shares of
its common stock on the open market under this program at an average price of
$12.46 per share.

5. EARNINGS PER SHARE

The computation of basic earnings per share is based on the weighted
average number of common shares outstanding during the year. Diluted earnings
per share is based on the weighted average number of common shares
outstanding during the year plus, when their effect is dilutive, common stock
equivalents consisting of shares subject to stock options. The following
table provides a reconciliation of the computations of basic and diluted
earnings per share information for each of the years in the three-year period
ended May 31, 1999.

In January 1998, the Board of Directors declared a three-for-two stock
split which was effected in the form of a stock dividend on February 23, 1998
to shareholders of record February 2, 1998, and a quarterly cash dividend of
8.5 cents per share on the increased shares, which effectively increased the
cash dividend payment by 6.25%. Prior year earnings per share amounts have
been restated to reflect the three-for-two stock split.

6. EMPLOYEE BENEFIT PLANS

The Company has defined contribution or defined benefit plans covering
substantially all full-time domestic employees and certain employees in The
Netherlands.

DEFINED BENEFIT PLANS

The pension plans for domestic, salaried employees have benefit
formulas primarily based on years of service and compensation. The pension
benefit for hourly employees is generally based on a fixed amount per year of
service. The Company follows the provisions of SFAS No. 87 "Employers'
Accounting for Pensions" and SFAS No. 132 "Employer's Disclosures about
Pension and Other Postretirement Benefits" for all pension and postretirement
plans.

6. EMPLOYEE BENEFIT PLANS -- (CONTINUED)

The Company's funding policy for domestic plans is to contribute
annually, at a minimum, an amount which is deductible for Federal income tax
purposes and that is sufficient to meet actuarially computed pension
benefits. Contributions are intended to provide for benefits attributed to
service to date and for benefits expected to be earned in the future. The
assets of the pension plans are invested primarily in mutual funds, common
stocks, investment grade bonds and U.S. Government obligations.

Certain foreign operations of domestic subsidiaries also have pension
plans. In most cases, the plans are defined benefit in nature. Assets of the
plans are comprised of insurance contracts. Benefit formulas are similar to
those used by domestic plans. It is the policy of these subsidiaries to fund
at least the minimum amounts required by local law and regulation.

The following table sets forth the plans' funded status, including the
change in plan assets, and the amount recognized in the Company's
Consolidated Balance Sheets.

6. EMPLOYEE BENEFIT PLANS -- (CONTINUED)

The projected benefit obligation for domestic plans is determined using
an assumed weighted average discount rate of 7.5% for fiscal 1999 and 1998,
and an assumed average compensation increase of 5.0%. The expected long-term
rate of return on assets is 10.0% for fiscal 1999 and 1998. The unrecognized
actuarial losses, prior service cost and transition obligation are amortized
on a straight-line basis over the estimated average future service period.

The projected benefit obligation for nondomestic plans is determined
using an assumed weighted average discount rate of 5.5% for fiscal 1999 and
1998, and an assumed average compensation increase of 2.0% for the first two
years and 4.0% thereafter. The expected long-term rate of return on assets is
6.5% for fiscal 1999 and 1998.

Pension expense charged to results of operations includes the following

DEFINED CONTRIBUTION PLAN

The defined contribution plan is a profit sharing plan which is
intended to qualify as a 401(k) plan under the Internal Revenue Code. Under
the plan, employees may contribute up to 15.0% of their pretax compensation,
subject to applicable regulatory limits. The Company may make matching
contributions up to 6.0% of compensation. Participants vest on a pro-rata
basis in Company contributions during the first three years of employment.
Expense charged to results of operations was $1,491, $1,174 and $930 in
fiscal 1999, 1998 and 1997, respectively.

DIRECTOR, EXECUTIVE AND KEY EMPLOYEE RETIREMENT BENEFIT AND PROFIT SHARING
PLANS

The Company provides its outside directors with benefits upon
retirement on or after age 65 provided they have completed at least five
years of service as a director. Benefits are paid quarterly in cash in an
amount equal to 25.0% of the annual retainer fee payable by the Company to
active outside directors. Payment of benefits commences upon retirement and
continues for a period equal to the total number of years of the retired
director's service as a director to a maximum of ten years, or death,
whichever occurs first.

6. EMPLOYEE BENEFIT PLANS -- (CONTINUED)

The Company also provides supplemental retirement and profit sharing
benefits for current and former executives and key employees to supplement
benefits provided by the Company's other benefit plans. The plans are not
fully funded and may require funding in the event of a change in control of
the Company as determined by the Company's Board of Directors. Expense
charged to results of operations for these plans was $1,162, $1,231 and $970
in fiscal 1999, 1998 and 1997, respectively.

POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company provides health and life insurance benefits for certain
eligible employees and retirees under a variety of plans. Generally these
benefits are contributory with retiree contributions adjusted annually. The
postretirement plans are unfunded and the Company has the right to modify or
terminate any of these plans in the future, in certain cases, subject to
union bargaining agreements. In fiscal 1995, the Company completed
termination of postretirement healthcare and life insurance benefits
attributable to future services of collective bargaining and other domestic
employees.

Postretirement benefit cost for the years ended May 31, 1999, 1998 and
1997 included the following components:

The assumed discount rate used to measure the accumulated
postretirement benefit obligation was 7.5% at May 31, 1999 and 1998. The
assumed rate of future increases in healthcare costs was 7.5% and 8.1% in
fiscal 1999 and 1998, respectively, declining to 5.25% by the year 2004 and
remaining at that rate thereafter. A one percent increase in the assumed
healthcare cost trend rate would increase the accumulated postretirement
benefit obligation by approximately $43 as of May 31, 1999 and would not
result in a significant change to the annual postretirement benefit expense.

7. COMMITMENTS AND CONTINGENCIES

The Company leases certain facilities and equipment under agreements
that expire at various dates through 2011. Rental expense under these leases
was $9,843, $6,991 and $6,660 in fiscal 1999, 1998 and 1997, respectively.

Future minimum payments under leases with initial or remaining terms of
one year or more at May 31, 1999 were $11,222 for fiscal 2000, $3,526 for
fiscal 2001, $2,836 for fiscal 2002, $1,925 for fiscal 2003 and $2,298 for
fiscal 2004 and thereafter.

The Company routinely issues letters of credit, performance bonds or
credit guarantees in the ordinary course of its business. These instruments
are typically issued in conjunction with insurance contracts or other
business requirements. The total of these instruments outstanding at May 31,
1999 was approximately $22,700.

The Company is involved in various claims and legal actions, including
environmental matters, arising in the ordinary course of business. In the
opinion of management, the ultimate disposition of these matters will not
have a material adverse effect on the Company's consolidated financial
condition or results of operations.

8. INVESTMENT IN LEVERAGED LEASES

From time to time, the Company acquires aircraft under lease that
qualify for leveraged lease accounting treatment. Typically, these are
long-term leases of late-model aircraft operated by major carriers where the
Company is an equity participant of at least twenty percent and there is a
third-party provider of nonrecourse debt of the remaining equipment cost.

During the lease term the Company is required, in accordance with SFAS
No. 13, to adjust the elements of the investment in leveraged leases to
reflect changes in important economic assumptions, such as the renegotiating
of the interest rate on the nonrecourse debt or changes in income tax rates.
In addition, the Company may sell options or other rights to the residual
proceeds over the book value at the end of the lease term.

The Company's net investment in leveraged leases is comprised of the
following elements:
