Which action provides physical support to the landing gear during maintenance to prevent collapse or rotation?

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

Answer: (C)

Providing physical support to the landing gear during maintenance means taking the weight off the gear and keeping it from moving or rotating. This is done by placing the aircraft on jacks properly positioned at the approved jacking points. When the gear is supported by jacks, hydraulic pressure cannot cause it to collapse or shift, making it safe to work on the gear components.

Wheel chocks help prevent the aircraft from rolling along the ground, but they do not stabilize the landing gear itself under load or stop rotation of the gear assembly. Lockout/tagout procedures are about preventing unintended re-energizing of systems, not about mechanically supporting the gear. Wearing PPE protects personnel, but it does not provide the physical restraint or support the gear needs during maintenance.
