The front bearing for a landing gear trunion is carried by a rear wing spar and the rear bearing is carried by a landing gear beam which is pivotly 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 projects 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.

A fused single pin connection between two structural members, comprising:
A fused single pin connection according to any of claims 1, 3, 2, 4, 5 and 10-15, wherein the load carrying capacity of the two shear pins is different.
In an aircraft, a generally horizontally extending landing gear beam for supporting the rear end of a landing gear trunnion, said beam including pivot pin means connecting its inboard end to a body frame portion of an aircraft and its outer end to a wing frame means, and the improvement comprising a fused single pin connection between the outboard end of said beam and the wing frame means, comprising:
The improvement of claim 20, wherein the upper shear pin has a larger load carrying capacity than the lower shear pin.
