WILMINGTON, Ohio — January 25, 2013 — Airborne Maintenance and Engineering Services, Inc. (AMES) completed the replacement of the aft pressure bulkhead of a Boeing 767-200 freighter aircraft for customer ABX Air, Inc.

Boeing selected the candidate aircraft and worked closely with the AMES team to ensure the accuracy and applicability of the Service Bulletin.

“Aside from Boeing, we are unaware of any operator or MRO that has completed this workscope on a Boeing 767 aircraft,” said AMES Vice President of Technical Operations Jim Savastano.

The aft pressure bulkhead is an integral, dome-shaped section of the airframe of a large commercial aircraft, situated between the cabin and the tail, that allows cabin pressure to be maintained.

The overall removal and reinstallation activity for the first aircraft took approximately 30 days to complete with all necessary equipment and tooling, documentation and replacement materials on-site at the start. A time-lapse video of the project can be viewed online at www.airbornemx.com.

“The success of this project reinforces the value of teamwork across several departments and organizations,” explained Savastano. “The AMES project team expended many hours in preparation, detailed research, and work instruction document preparation including tooling and equipment planning.”

“ABX Air was very pleased with AMES’ performance on this project,” remarked ABX Air Manager of Engineering Joe Freese. “The engineering documentation, coordination of specialized equipment, and detailed planning that went into this project contributed significantly to the success.” Both ABX Air and AMES are wholly owned subsidiaries of Air Transport Services Group, Inc (NASDAQ:ATSG).

“Our extensive background with the Boeing 767 aircraft positioned us well to take on this [Aft Pressure Bulkhead] replacement project,” added Savastano. “With our first APB replacement completed, we are scheduling similar work packages in the near future.”
