Title: Locator for a gearbox mount

Abstract: A locator for a gearbox mount for a gas turbine engine includes a mounting plate having a first stub shaft that extends from the plate into a receptacle in the gearbox, a second stub shaft that extends from the plate into a receptacle in the engine case and a load sensitive mechanism disposed in either one of the stub shafts. During a high rotor imbalance event such as a fan blade loss condition, the load sensitive mechanism shears to partially decouple the gearbox from the engine case to minimize damage caused by high rotor imbalance loads. Alternate embodiments of the load sensitive mechanisms in the stub shaft are disclosed, including a diaphragm and a wall that yield to shear loads.
