Abstract: A door stop includes a scissor link member including a pair of links pivotably coupled together at a central pivot point. The scissor link member has a first end pivotally coupled to a door and a second end pivotally coupled to a floor. The pair of links are configured to abut against one another adjacent the central pivot point when the door is fully open to prevent pivoting at the central pivot point for holding the door open. The scissor link member is releasable such that the pair of links pivot about the central pivot point when the scissor link member is released, thereby enabling closing of the door. The pair of links fold into a nested arrangement when the door is fully closed. The pair of links are configured to deform under dynamic loads to protect the surrounding aircraft structure and indicate a need for inspection.
