When must helicopters be dearmed?

• A. Before maintenance inspections
• B. Immediately after landing
• C. Prior to installation of tie-downs/chocks
• D. Once fuel levels are confirmed

Answer: (C)

Helicopters must be dearmed prior to the installation of tie-downs and chocks to ensure the safety of personnel and equipment on the flight deck. This procedure is critical as it prevents any accidental discharge of weapons or munitions during the securing process. By removing the armaments first, it mitigates the risk associated with handling and securing the aircraft, allowing for a safer environment for both the ground crew and the aircraft itself. The timing of dearming is essential because the tie-downs and chocks secure the aircraft in position, and doing so with armaments still installed poses an unnecessary risk. Once the helicopter is properly dearmed, the crew can proceed to safely install tie-downs and chocks without the fear of potential hazardous incidents. Choosing to dearm the helicopter after landing or before maintenance does not specifically highlight the critical step of safety during the securing process, while confirming fuel levels, although important, does not relate directly to the urgency of dearming before securing the aircraft on the deck.
