Abstract
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.
