AAR'S Order Backlog Continues to Strengthen -- Company to Announce Second Quarter 2004 Results on December 18

WOOD DALE, Ill., /PRNewswire-FirstCall/ -- AAR (NYSE: AIR) announced today that its order backlog has increased $45 million, or 44 percent, since the beginning of its fiscal year in June. The increase is driven primarily by orders for the Company's rapid deployment solutions, manufactured cargo systems and airframe maintenance services.

"We continue to make significant progress in our key markets. Demand for our Mobility Systems' products remains strong and we expect this trend to continue as the U.S. Military seeks a more rapidly deployable force," said AAR President and CEO, David P. Storch. "The backlog at our airframe maintenance facility in Oklahoma has doubled since the beginning of the year, reflecting our selection by customers like Alaska Airlines and Mesa Air Group to provide a variety of light-to-heavy maintenance on aircraft in their fleets. We've also won several new orders for cargo systems, designed and manufactured for the conversion of wide-body aircraft."
