An engine mounting system where an aft body mounted counter-rotation prop fan engine is mounted to aircraft structure. The engine is connected through a longitudinally extending beam to a mounting strut structure comprising a fore spar, a mid spar and a rear spar. Vertical loads and lateral loads are transmitted from the engine to the beam at forward and rear locations, and these vertical and lateral loads are in turn transmitted to the spars at forward and rear locations. The torque loads from the engine are transmitted at a selected location into the beam, and then transmitted through the beam to the spar or spars at a selected location or locations. The beam can initially be mounted to either the engine or to the spars of the aircraft.
