WOOD DALE, ILLINOIS (March 5, 2008) - AAR (NYSE: AIR) announced today that it has completed the acquisition of Avborne Heavy Maintenance, Inc.

The acquisition significantly increases the Company's MRO capacity, workforce and capabilities. The move adds 226,000 square feet of modern hangar space at Miami International Airport and 467 aviation maintenance technicians (AMTs), increasing AAR's hangar space by 22 percent and bringing the total number of AMTs at AAR to more than 2,000 worldwide.

"We're very impressed with the strong management team, skilled workforce and the high levels of customer satisfaction that they've achieved at Avborne," said David P. Storch, Chairman and Chief Executive Officer of AAR CORP.
