Abstract: An attachment assembly for securing a secondary door to a mating structure may include a door frame and at least one telescoping structural pin disposable within a side of the door frame. The structural pin may be extendable from a retracted position to a deployed position into the mating structure.

Abstract: An attachment assembly may be adapted for securing a panel member such as a class divider or a secondary door to a mating structure. The attachment assembly comprises at least one structural pin configured to be extendable from a retracted position to a deployed position. The attachment assembly may include a base support configured to be placed in overlapping contact with the panel member. The attachment assembly may include a primary support configured to be mountable such as in overlapping contact to the base support and having at least one sleeve sized and configured to receive the structural pin which is telescopically movable. A locking mechanism such as a quick release pin may be inserted through bores formed in the sleeve and in the structural pin to prevent axial movement of the structural pin relative to the sleeve.

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.
