An aircraft door sealing system for use with an aircraft door. The aircraft door is movable between open and closed positions with respect to a door frame. The door has a peripheral door opening portion and a peripheral door seal portion. The door frame has a peripheral frame opening portion and a peripheral frame seal portion. The frame opening portion is aligned adjacent the door opening portion when the door is in the closed position. The frame seal portion is aligned adjacent the door seal portion when the door is in the closed position. The sealing system is provided with an elastic seal which is interposed between the door and the door frame. The seal is attached to the door seal portion and the frame seal portion. The seal is expandable and contractible for permitting movement of the door between the open and closed positions thereof. The seal has a pair of seal opening edges disposed between the door opening portion and the frame opening portion. An opening is collectively defined by the door opening portion, the frame opening portion and the seal opening edges when the door is in the open position for facilitating access through the opening and the door frame.
