Abstract
A multi-section aircraft door includes a sliding joint permitting a lower door section displacement into the flight deck area. The door includes an upper door section having a lower edge. The lower edge is connectably joined to an upper member of a two-member sliding joint. The upper member slidably joins to a sliding joint lower member. The sliding joint lower member is connectably joined to a lower door section upper edge. The upper member and the lower member of the two-member sliding joint include paired apertured embossments. A frangible pin slidably mates in each apertured embossment pair. A lever and cam form a frangible pin removal assembly. The lever is held in a normally upright position by either a spring device or a clevis and pin assembly. A rotating clasp or a ball détente system can also replace the frangible pin/apertured embossment and cam/lever.
