Abstract: A flap support mounting assembly employs a flap support having at least one laterally-oriented upper coupling and a pair of laterally-oriented lower couplings. A fail-safe pin engages the at least one laterally-oriented upper coupling to an upper rear-spar fitting. A pair of frangible pins engages the lower couplings to a pair of lower rear-spar fittings. The frangible pins are configured to shear and enable the flap support to rotate upwards about the fail-safe pin in response to a load induced on the flap support that creates a moment inducing a sufficient shear force to shear the frangible pins. The fail-safe pin is configured to shear allowing separation of the flap support and associated flap from the wing in a manner that inhibits damage to a rear spar and integral fuel tank in a wing structure.

Abstract: A hinge assembly which creates a zero backlash situation. The base member has multiple seats, each having two contact ridges. The contact ridges are formed by an intersection of two planes (ideally substantially ninety degrees). A ball interconnect is engaged by the contact ridges of the seat on one side and a similar arrangement of contact seats on the other side (the hinge member). The diameter of the ball interconnect is larger than the distances between the contact ridges. By sandwiching the ball interconnect between the contact ridges of the base member and the contact ridges of the hinge member, a zero backlash is created in which firm and positive contact is maintained between the elements of the hinge.
