A gearbox mounting arrangement for a gas turbine engine includes a controlled spring rate mount that has an appropriate stiffness level to minimize the transmission of loads from the engine case to the gearbox. The controlled spring rate mount is generally T-shaped and includes a cross-member that attaches at the ends thereof to spaced locations on the engine case and a substantially perpendicular leg fixed to the cross-member and having a free end that attaches to the gearbox. The cross-member bends to accommodate the application of vertical loads from the engine case to the gearbox instead of transmitting the loads to the gearbox which would deform the gearbox housing during a high rotor imbalance event.
