A thrust reverser actuation structure utilizing a single power source (60) for controlling the operation of thrust reverser actuators (26, 40) associated with plural jet engines (12, 16). The thrust reverser actuation structure has a power drive unit (60, 74) with an output shaft (62) that can be located in the fuselage of an aircraft and a pair of mechanical drive trains (68, 70) extend therefrom and are connected separately to the thrust reverser actuators (26, 40) of jet engines (12, 16) located on opposite wings of an aircraft. With the single power source (60) and the mechanical drive train the occurrence of a jam in the thrust reversers of one jet engine will result in stopping the power drive unit and the thrust reversers of the other engine at the same position as those that are jammed. This minimizes the likelihood of asymmetric reverse thrust.
