Abstract: An aircraft engine nacelle door operating system locking manual drive unit includes a housing, an input drive shaft, an output drive shaft, a lock shaft, and a lock spring. The input drive shaft, the output drive shaft, and the lock shaft are all rotationally mounted in the housing. The output drive shaft continuously engages and mates with the input drive shaft, and he lock shaft extends at least partially into and engages the input drive shaft. The lock shaft is movable between a lock position, in which it engages and mates with the output drive shaft, and an unlock position, in it is disengaged from the output drive shaft. The lock spring supplies a bias force to the lock shaft that urges the lock shaft toward the lock position.
