Abstract
A plug type door for a pressurizable aircraft fuselage is mounted by a door hinge assembly for swinging movement into and out of a door opening in the fuselage. The door is composed of three segments that are hinged to each other so that the door can be folded from a fully closed position in which the three segments are serially arranged to completely cover the door opening, into an unplugged position in which the three segments are oriented in a generally Z-shaped configuration. Stop members are mounted on the fuselage adjacent the door opening and cooperate with corresponding stop members on the door to plug or secure the door in the door opening when the door is in a closed position. The stop members on the door and the door opening deregister as the door is folded to free the door for outward swinging movement about the hinge assembly.
