Abstract: A system and method for unlatching an aircraft door is disclosed. The system includes a latch pin design which enables retraction of the pin in the event the ordinary unlatching mechanical systems fail. The system includes the use of a rod that is reversely threaded on each side. Rotation of the rod either extends or retracts the pin.

Abstract: A system and method for defeating a door lock. More specifically, a door having an outside door handle with a key-lock, and having an interior door handle of the type that includes both a paddle along with the handle runs the risk of being left in locked mode in the event of a mechanical malfunction. This problem has been overcome by mechanically linking the paddle on the interior handle to unlatch the key-lock.

Abstract: An aircraft door system and related closure method. The system involves the use of a ball transfer device as an initial contact made in the closing of an aircraft door. The closing door next encounters guiding and fitting arrangements are also employed to laterally align the lower portion of the aircraft door with the corresponding portion of the frame upon the closing. Finally, the closing door then encounters load path ties which are employed about the door. The arrangement above allows the door refit the door within what is a deformed doorframe due to weight and structural considerations.
