Abstract
A plug type door intended particularly for use on a military cargo type aircraft is designed to enable its ejection if necessary. To do this, an operating device such as a handle (28) simultaneously controls retraction of hinge pins (16c) from the hinges about which the panel (10) of the door is hinged to its frame (12) and retraction of the mechanical elements (21) against which the stops (19) fitted on the panel usually bear by gravity, when the door is closed. Furthermore, guide ramps connected to the frame (12) and in which the rollers supported by the panel (10) open downwards, to enable the panel (10) to drop by gravity when the handle (28) is pulled.
