Abstract
A door for an enclosed space under pressure, such as an aircraft cabin, has redundant door stops secured to the door edges and cooperating with redundant frame stops secured to a door frame in an aircraft body. The door stops and the frame stops are arranged in pairs. A first pair of stops is effective under normal operating conditions to keep the door in a sealed position in the door frame. A second pair which is not transmitting any loads under normal operating conditions, becomes effective immediately when one and/or both stop components of the first pair fails. For this purpose the stop member and stop element forming the second pair are normally spaced from each other by a gap that is small enough to close instantly in response to failure of the first pair of stops.
