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.
