AEI's 10 pallet B737-300SF Freighter Conversion


The Aeronautical Engineers Inc. (AEI) B737-300SF Cargo Conversion per FAA STC ST01827LA, consists of the installation of a 86"x140" cargo door on the left side of the fuselage, and modification of the main deck to a Class E cargo compartment. After conversion the aircraft can carry ten containers or pallets; the only B737-300SF Freighter with this capability.

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 an 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.
