The system (100) comprises first and second pylon conversion actuators (102, 104) each having a retracted position and an extended position which corresponding to the aircraft mode and the helicopter mode. A first gearing system (156) is operably coupled to the first pylon conversion actuator (102) and to a first primary power unit (110), a first backup power unit (112) and a first clutch (138). A second gearing system (158) is operably coupled to the second pylon conversion actuator (104) and to a second primary power unit (114), a second backup power unit (116) and a second clutch (142). An interconnect drive train (126) is operably coupled to the first and second clutches (138, 142) such that the first and second pylon conversion actuators (102, 104) are operable between the extended position and the retracted position.
