A method and apparatus for a tracking door centering system. An apparatus may comprise an elongate member, a first centering track, and a second centering track. The elongate member may have a first end and a second end capable of being rotatably mounted to a door along an axis that may be substantially parallel to a horizontal centerline. The first centering track may be mounted on the first end. The second centering track may be mounted on the second end. The first centering track and the second centering track may be movable to reduce rotational movement of the door during movement of the door about a vertical centerline when a first follower is engaged in the first centering track and a second follower is engaged in the second centering track.

Translating door centering system

A method and apparatus for aligning a swing tail cargo door. An alignment system comprises an alignment ramp, a set of pull-in hook mechanisms, and a set of lock trains. The alignment ramp may be configured for initial alignment between a swing tail cargo door and an aircraft fuselage during closing of the swing tail cargo door. The set of pull-in hook mechanisms may be disposed along an interface between the swing tail cargo door and the aircraft fuselage and may be capable of a final alignment between the swing tail cargo door and the aircraft fuselage during the closing of the swing tail cargo door. The set of lock trains may be disposed along the interface and may be capable of locking a plurality of latch actuators in the latched position.

Method and apparatus for closing a swing tail on an aircraft

A handle assembly for controlling an aircraft door latch mechanism so that the door can be opened or closed from either inside or outside the aircraft. The assembly includes an inner shaft that is connected to the latch mechanism so as to control the opening and closing of the door, and an outer shaft that overlaps the inner shaft and that can be telescopically extended away from inner shaft. An inside handle is attached to the inner shaft so as to rotate the shaft. Rotation of the outer shaft is controlled by an outside handle attached thereto. An inner clutch half is attached, by splines, to the inboard end of the outer shaft. An outer clutch half is attached, by splines, to the outboard end of the inner shaft. The clutch halves are normally spaced away from each other. When the outside handle and the outer shaft are extended, the clutch halves interlock so that the shafts will rotate in unison. An actuator disarming assembly with a translating pivoting crank is attached to the outer shaft. When the outside handle and the outer shaft are extended, the crank pivots to cause the disarming mechanism to disarm any actuator that may be attached to the door. This prevents inadvertent triggering of the actuator when persons outside the aricraft are trying to open the door.
