In an aircraft having a turbofan engine with a thrust reverser divided into two C-shaped cowl sections, a system for pivotally attaching each of the C-shaped cowl sections to the engine mounting strut for pivotal movement of the C-sections between a closed position adjacent the engine core and an open position spaced from the engine core, including first and second hinges cooperably attached to each half of the thrust reverser cowl and the engine mounting strut to define a hinge line associated with each cowl half. A third load transfer assembly is associated with each cowl half, each load transfer assembly having a first portion affixed to its associated engine cowl half and a second portion affixed to the engine mounting strut, both offset from the hinge line but within the contour of the engine cowl. The first and second portions engaging one another when the cowl half is in the closed position to act as a load transfer point for thrust loads to the engine mounting strut and disengaging when the cowl is in the open position. Preferably, the first portion is an arcuate slider block and the second portion is an arcuate channel that accepts the slider block when the cowl is in the closed position, both the arcuate slider block and the arcuate channel having their centers of curvature located on the hinge line.
