Which action is taken to physically stabilize the aircraft during landing gear service to maintain a safe work plane?

• A. Wheel chocks
• B. Lockout/tagout procedures
• C. Support aircraft with jacks
• D. Wear PPE

Answer: (C)

Stabilizing the aircraft for gear service means holding it in a fixed position so it won’t move while maintenance is performed. The way to achieve this physically is to support the airplane with jacks at the designated jacking points, bearing the weight of the aircraft and keeping it level. This creates a safe work plane where technicians can access the landing gear without the risk of the aircraft shifting, sinking, or tipping. Wheel chocks prevent rolling on the ground but don’t provide the vertical support or controlled height needed during servicing. Lockout/tagout procedures deal with energy isolation, not stabilization, and wearing PPE protects the worker without stabilizing the aircraft. So, using jacks to support the aircraft is the correct approach for safe, stable gear maintenance.
