The U.S. Federal Aviation Administration approved Air Transport Services Group’s passenger-to-FlexCombi conversion program for the Boeing 737-700 Next Generation aircraft.

ATSG said the FAA issued a supplemental type certification for its conversion design for the Boeing 737-700, offering customers two different main-deck freight and passenger configurations as well as full-freighter mode. The aircraft will be marketed as B737-700FC (FlexCombi). PEMCO Conversions, a division of ATSG subsidiary Pemco World Air Services, developed and managed the program from its headquarters in Tampa, FL.

“To reach this moment in the development of our 737-700 passenger-to-freighter conversion program solidifies our presence as a global leader in the marketplace,” Mike Andrews, director of conversion programs for PEMCO, said. “We are pleased with the performance of our Tampa cargo conversion team and continue to develop innovative products meeting increased customer demand for 737 conversions.”

The launch customer for the PEMCO B737-700FC is Bahrain-based Chisholm Enterprises, a provider of aviation and business solutions in the Middle East. Its subsidiary Texel Air, a non-scheduled cargo airline, will operate the B737-700FC from Bahrain International Airport.

“Chisholm is a great partner that provides unique services in its market, so the flexibility of our 737 conversion products continues to meet Chisholm’s needs as its fleet grows,” Jeff Becker, general manager of PEMCO, said.

Now that the 737-700 conversion program has received FAA approval, PEMCO plans to seek certification from the European Aviation Safety Agency and the Civil Aviation Administration of China.

The PEMCO B737-700FC (FlexCombi) offers three configurations: a 24-seat cabin plus a 2,640-cubic-foot cargo hold for up to 30,000 pounds of payload in six pallet positions, a 12-seat cabin plus a 3,005-cubic-foot cargo hold for up to 35,000 pounds of payload in seven pallet positions or full-freighter mode consisting of a 3,370-cubic-foot cargo hold for up to 40,000 pounds of payload in eight pallet positions. The available positions will accommodate 88” x 125” or 88” x 108” pallets, with the seventh and eighth positions accommodating smaller pallets.

PEMCO also is developing a B737-700F full-freighter conversion program. Those freighters would feature nine pallet positions, up to 45,000 pounds of payload and 3,844 cubic feet of total volume. The available positions will accommodate 88” x 125” or 88” x 108” pallets, with the ninth position accommodating a smaller pallet.
