Abstract
A locking assembly partially housed between a forward bulkhead and an aft bulkhead of an aircraft's fan duct for preventing a pivot door of a thrust reverser from inadvertently opening during flight and providing over-stow assistance during opening and closing of the pivot door. The locking assembly may comprise a lock arm configured to mate with a lock arm receiver fixed to the pivot door. The lock arm may have a first portion pivotally attached to a locking assembly housing mounted between the bulkheads, and a second portion extending aftward through an opening in the aft bulkhead. When the lock arm is pivoted away from the pivot door, the second portion may be configured to push inward against the lock arm receiver, urging the pivot door inward while simultaneously moving the lock arm away from the lock arm receiver to allow the pivot door to open outward.
