ABSTRACT:
A banner towing adapter for use in the towing of a banner or target by an rcraft of the type having an arresting tail hook assembly. The towing adapter is installable in the hollow tail hook attachment pin of the aircraft by means of an expanding sleeve. The sleeve is fixed to a first upwardly extending immovable arm which secures the sleeve to the tail hook support structure located on the aircraft. A second arm, rotatably attached to the sleeve and coupled to the tail hook, is provided at its distal end with a hook suitable for securing a towline from the banner to be towed. The towline securing hook is disposable between two hook retainers which act as a constraint when the towline is on the hook. One of the retainers is disposed at the far end of the first arm while the other hook retainer is rotatable about a point fixed on the first arm. The second retainer is lockable in a retaining position by a ball lock pin. When the tail hook moves to the down position away from the aircraft the hook is rotated away from the retainers thus releasing the towline and the attached banner.
