The Lock Assembly on the Leonardo AW-101 is a manually retractable cargo restraint system designed to secure Unit Load Devices (ULDs) during flight, meeting stringent load requirements to ensure mission safety. It is positioned along the forward and aft edges of each ULD, except the forward edge of the first ULD in the cargo area. This assembly engages automatically or manually to hold cargo firmly in place under all flight conditions. Engineered for reliability and ease of operation, the Lock Assembly retracts when not in use to allow unobstructed loading and unloading, while its robust design withstands repeated engagement cycles in demanding environments. This precision restraint solution is integral to maintaining stability,  protecting cargo, and ensuring efficient handling for a wide range of operational missions.
