Aeronautical Engineers, Inc. (AEI) has announced Transport Canada Civil Aviation has approved AEI’s STC (ST02690LA) for the 12-pallet position B737-800SF freighter conversion. AEI currently has FAA, CAAC, EASA and now TCCA approvals for its B737-800SF.Last month AEI announced a contract to provide Chrono Aviation with a B737-800SF freighter conversion, which represents AEI’s first Canadian-based customer. The AEI converted B737-800SF freighter offers a main deck payload of up to 52,700 lbs. (23,904 kg) and incorporates eleven full height 88” x 125” container positions, plus an additional position for an AEP/AEH. The conversion also incorporates new floor beams aft of the wing box, a large 86” x 137” Main Cargo Door with a single vent door system. AEI’s design allows for containers to be loaded into the aircraft a full 16.5” aft of the forward door jamb, ensuring ground operators have sufficient manoeuvring room which minimises potential door and aircraft strikes. Additionally, the AEI B737-800SF includes a flexible Ancra Cargo Loading System, a rigid 9g barrier, five supernumerary seats as standard, a galley, and full lavatory.
