A deformable aircraft door (10) which is movable between open and closed positions and is adapted to substantially maintain contact with the door frame (12) for reducing a perimeter gap between the door (10) and the door frame (12). The aircraft door (10) comprises an edge portion (14) which is formed to engage the door frame (12), and an elastic portion (16) which is attached to the edge portion (14). The elastic portion (16) is selectively expandable and contractible for permitting movement of the edge portion (14) relative to the door frame (12) when the aircraft door (10) is in the closed position so as to substantially maintain contact between the edge portion (14) and the door frame (12) despite changes in the geometry of the door frame.
