Abstract

A tertiary lock system (20) for an aircraft thrust reverser, comprising: a lock member (22) actuatable between a locked position, in which a loadpath of the lock member (22) engages a movable component (10) to prevent deployment of the thrust reverser, and an unlocked position, in which the lock member (22) permits deployment of the movable component (10) of the thrust reverser; wherein the lock member comprises an element (30) arranged such that at least a portion of the element extends into or through the loadpath of the lock member; and a locking verification system (50) including a sensor module (52) arranged for interrogating the element when the lock member is in the locked position; wherein the locking verification system is configured to: confirm that the tertiary lock system has been commanded to actuate the lock member into the locked position; instruct the sensor module to interrogate the element; and verify that the lock member is in the locked position and the loadpath is uncompromised in response to determining that the element is intact.
