The invention discloses an aviation closing lock catch. The aviation closing lock catch comprises a handle, a locking mechanism, a lock hook and a trigger, wherein the handle is provided with a containing cavity, and the trigger is arranged in the containing cavity; the locking mechanism is hinged to the end of the containing cavity of the handle, and a locking mechanism pin shaft is arranged on the side wall of the locking mechanism; the locking mechanism pin shaft is matched with a clamping groove in the trigger to lock and loosen the locking mechanism; an outer arm torsion spring used for pushing the locking mechanism to be automatically bounced off during loosening is arranged at the hinged joint; and the lock hook is connected with the end of the locking mechanism. Locking and loosening of the locking mechanism are achieved through opening and closing of the aviation closing lock catch. The problem that no related product exists in the current market is solved, and the aviation closing lock catch can be applied to important parts such as an aero-engine external nacelle and an aircraft cabin door.
