Abstract
In a jet aircraft having a drive which rotatably drives an airframe mounted accessory drive (12), a system for controlling the connection of the drive to the airframe mounted accessory drive is disclosed which permits the manual connection and disconnection of a rotatable shaft (18) from a driven shaft (22) with high reliability by a manually movable handle (30) which is connected to a fork (88) which is rotatable between first and second positions which translates a movable carrier (20) which carries the driven shaft between first and second positions. The system has minimal backlash which insures high integrity in sensed positions of the system which is necessary for safe operation of the aircraft. Furthermore, a safety interlock (44) is provided which is activated by pressurized hydraulic fluid from the airframe mounted accessory drive to prevent translation of the carrier (20) and the rotatable shaft (22) during operation of the aircraft or driving of the airframe mounted accessory drive by an auxiliary power unit (21) during testing of the on board generator (17) or hydraulic pump(s) ( 19).
