WILMINGTON, Ohio — February 19, 2013 — Airborne Maintenance and Engineering Services, Inc. (AMES) announced that it signed an agreement with DHL to provide heavy maintenance services for at least twenty-eight (28) C checks over three years on DHL-owned and leased Boeing 767-200F aircraft currently operating in the U.S. network.

The agreement, which runs from April 2013 through March 2016, covers 767 freighters operated for DHL by ABX Air, another subsidiary of AMES’ parent company, Air Transport Services Group, Inc. (NASDAQ:ATSG). AMES has provided scheduled maintenance for these aircraft under a different arrangement since May 2009.

“DHL is confident in AMES’ ability to support our maintenance requirements through their quality workmanship, which is reflected in our continued 767-200F fleet reliability,” remarked David Sheedy, Network Technical Director for DHL Aviation Americas. “They remain committed to consistently delivering the highest quality product whilst striving for improved efficiencies to ultimately reduce cost for their customers.”

“Repeat business is in many ways a result of your overall value to a customer,” commented AMES President Brady Templeton. “This is truly a significant accomplishment and reflective upon our greatest resource, our employees, and the efforts of those who remain diligent in delivering high-quality products and services on a predictable schedule at a fair price.”

A C check is a periodic maintenance visit during which an aircraft undergoes a comprehensive inspection and service procedure as part of its overall maintenance program.
