WOOD DALE, ILLINOIS (May 7, 2010) — AAR announced today that its Landing Gear Services center was recognized as the best landing gear, wheels and brakes services provider at the recent MRO Americas 2010 Conference held in Phoenix, Arizona.

AAR was one of only two companies to receive multiple awards in the program, earning recognition in both the Landing Gear Services and Wheels and Brakes Services categories.

“We are proud to be recognized as the best overall provider of landing gear, wheels and brakes services,” said Timothy Romenesko, President and Chief Operating Officer of AAR CORP. “The recognition is the result of our employees’ solid execution and enduring commitment to providing excellent service and support for our customers."

Nominations were solicited from and voted on by more than 13,500 industry professionals.

AAR offers a full range of MRO, supply chain and precision fabrication services and provides landing gear maintenance and exchange services for virtually every type of major commercial, regional and military passenger aircraft in use today.
