What action is required for an unserviceable ADS?

When dealing with an unserviceable ADS (Aerial Delivery System), the correct action is to stencil it "unserviceable" and dispose of it properly. This process serves multiple purposes: it clearly indicates to all personnel that the item is not fit for use, thereby preventing its accidental deployment, and it ensures that the unserviceable item is managed according to safety and logistical protocols.

Marking items as "unserviceable" is crucial in maintaining accountability and safety standards within air delivery operations. Proper disposal is essential to prevent any potential hazards that could arise from using an item that is not functioning correctly. In contrast, simply painting an item black, storing it for future use, or reinstating it for repairs does not address the immediate concern of ensuring that the unserviceable equipment is clearly marked and handled in a way that reflects its status. This meticulous attention to detail is critical in military operations to ensure operational readiness and safety.
