Abstract: A removable stowage bin assembly for quick conversion of an aircraft between a passenger-carrying mode and a cargo-carrying mode includes a stowage bin and a first assembly comprised of a clevis fitting attached to the framework of the aircraft and a hook attached to the stowage bin, the hook being removably and pivotally attachable to the clevis fitting. A second assembly is comprised of a tie rod having a first end pivotally attached to the framework of the aircraft and a bracket attached to the stowage bin. The tie rod has a second end attachable to the framework of the aircraft in a cargo-carrying mode and attachable to the bracket on the stowage bin in a passenger-carrying mode. A third assembly is compromised of a female fitting having an opening and attached to one of the framework of the aircraft and the stowage bin, and a male fitting having a protrusion and attached to the other of the framework of the aircraft and the stowage bin.
