The front bearing for a landing gear trunnion is carried by a rear wing spar and the rear bearing is carried by a simple beam which is pivotally attached at its inner end to the body frame. A main attach pin pivotally connects the outer end of such beam to a pair of connector plates, one located on each side of the connection. A pair of shear pins connect the connector plates to a short cantilever beam which is connected to and project inwardly from the rear wing spar, generally in line with the landing gear beam. One of the shear pins is positioned generally horizontally outwardly from the main attach pin. The second shear pin is positioned generally vertically below the main attach pin. Generally vertical overloads are carried by the lower shear pin load and such shear pin is designed to fracture in response to a load slightly below the vertical load reacting capability of the reaction structure. Generally horizontal overloads are carried by the upper pin or by both pins together which are sized to break under loads slightly below the horizontal load reacting capability of the reaction structure. Control system elements for use in flying the aircraft extend along the wing spar forwardly of the fused connection so that they are not damaged by the landing gear breaking away.
