AEI's 12 pallet B737-800SF Freighter Conversion


The Aeronautical Engineers Inc. (AEI) B737-800SF Cargo Conversion consists of the installation of a 86" x 137" cargo door on the left side of the fuselage, and modification of main deck to a Class E cargo compartment.  After conversion the aircraft can carry eleven 88" x 125" AAA full height containers or pallets plus one AEP/AEH, with pallet weights up to 9,000 lbs. AEI's B737-800SF is now ETOPS 180 approved.

AEI's cargo door has earned a reputation of being the most robust and reliable in the conversion industry.  The cargo door is hydraulically operated and actuated from the inside of the aircraft by a independent system.  Hydraulic pressure is available from two sources: a 28VDC electrically operated hydraulic pump or a manual hand pump.  The door control and manual pump are located on the 9g barrier, allowing a single person to operate the door manually.
