A door assembly for covering an opening (12) formed in the body (26) of an aircraft including a door (10) with two gooseneck hinge arms (28) are rotatably connected at one end to the aircraft body above the door opening and rotatably connected at their other end to the door. An actuator (30) is provided to pivot the hinge arm about its rotatable connection to the body. Two mounting panels (106) are located between the two gooseneck hinge arms. A torque tube (104) is supported by the door and rotates by turning an interior door handle (100) that is located between the two mounting panels. The door assembly further includes a latching assembly (32), hinge guide assembly (34), and frame guide assembly (36) that cooperate to give the door a desired motion. The latching, hinge guide, and frame guide assemblies each include various rollers that engage with tracks. In operation, the torque tube (104) is rotated to cause the door (10) to move from a closed position to an open position in which the shape and orientation of the latching assembly (32), the hinge guide assembly (34), and the frame guide assembly (36) cause the upper edge of the door to initially move inward and downward relative to the body opening (12) while the lower door edge initially moves outward and downward relative to the body opening (12).
