An apparatus is provided for an assembly fixture for positioning a component having a pivot pin including a rigid member, a fixed positioning pin affixed to a first point on the rigid member for insertion in a first locating hole in an assembly, a component restraint affixed to a second point on the rigid member for applying a force to the component for retaining the component in a fixed position and orientation with respect to the assembly fixture, and a pivot positioning pin coupled to a third point on the rigid member by a flexible mounting assembly, the flexible mounting assembly facilitating a linear movement of the pivot positioning pin along a linear path.

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.

A stay includes a first arm rotatably connected to any one of a body or a door openable to the body; a second arm, one end of the second arm being rotatably connected to the first arm and the other end being connected to any one of the body or the door. The first arm includes a resilient body, a slider urged by the resilient body to the second arm. A case slidably supports the slider toward the second arm, and a pressing part is abutted and pressured onto a cam face disposed to the second arm by the slider. An adjustment mechanism changes a pressing position between the cam face and the pressing part to a crossing direction with respect to a sliding direction of the slider and a rotation shaft axis direction of the second arm.
