Abstract
A door actuation system for an outwardly opening aircraft door for use in an aircraft having a door opening, a cam post, and a plurality of latch pins. The door actuation system includes a locking mechanism operably coupled to the door, wherein the locking mechanism is positionable in a locked position preventing the door from being opened and an unlocked position. The system further includes a pull-in mechanism that is hydraulically actuated and includes a cam slot member capable of operably engaging the cam post of the aircraft. The pull-in mechanism is positionable in an uncammed position and a cammed position. A latching mechanism is also provided that is hydraulically actuated and includes a plurality of cam latches each capable of operably receiving one of the plurality of latch pins. The latching mechanism is positionable in a latched position and an unlatched position. The pull-in mechanism and the latching mechanism are capable of preventing opening of the door when the pull-in mechanism is in the cammed position and the latching mechanism is in the latched position, even if the locking mechanism is in the unlocked position.
