LOCKING LINEAR ACTUATOR

Locking linear actuators, thrust reversers for aircraft that include the locking linear actuators, and methods of manufacturing the locking linear actuators. The disclosed locking linear actuators (20) include an actuator housing (22) that defines an internal longitudinal bore (30), an actuator piston (28) and a lock sleeve (34). A portion of the actuator piston (28) defines a lock aperture (40), housing a locking tab (42) capable of radial movement. When the actuator is retracted, the locking tab engages with a step (46) in the surface of the bore to lock the linear actuator, a distal portion of the lock sleeve extends into a portion of the actuator piston to prevent the locking tab from disengaging from the step in the surface of the bore.
