ABSTRACT:
A latch pin and locking system for use in connection with an aircraft having folding wings or wing tips. The system includes a plurality of individual latch pin units, each of which has a pin that is hydraulically driven in extension and retraction. When extended, the pins cooperatively lock wing tip hinge structure which prevents wing tip folding movement. Each latch pin unit has a locking body that prevents pin retraction of its respective pin after extension thereof for wing tip locking. The locking bodies of all of the latch pin units are drivingly interlinked, so that all lock and/or unlock as a single network. The network is driven by a single power drive unit. In the event any one locking body in the network fails, the network is broken, and thereby provides an indication that maintenance is required.
