Abstract
An external door for use in accessing a cargo area of an aircraft fuselage. The door includes a locking system, a latching system, a lock monitoring system, an uplock used to secure the door in an open position, and an actuating system that assists in at least one of opening and closing the door. The locking system works by interfering with the movement of the latching system components. The locking system includes a monitoring device that prevents the aircraft from being pressurized in case of a malfunction in the locking system. The latching system includes a handle locking system that prevents operation of the latch handle by accident or by ground loading or flight forces. The systems of the door are preferably manually operated, and utilize rigid members.
