What is the purpose of jacking points and safety blocks when performing landing gear maintenance?

• A. Provide stable support for the gear during maintenance; safe blocking prevents gear collapse and ensures level access.
• B. To weigh the aircraft.
• C. To decorate the hangar floor.
• D. To store spare parts.

Answer: (A)

When you work on landing gear, you need a stable, controlled setup so components can be inspected, repaired, or replaced safely. Jacking points are specially reinforced areas on the airframe or gear structure chosen to carry the load of lifting equipment without causing damage. They let you raise the airplane to the proper height needed to access the gear components. Safety blocks or chocks are placed to prevent any movement—no rolling, no lowering of the gear if hydraulic pressure shifts, and to keep the system level so you can work accurately. Together, they provide a secure, level support that protects both personnel and the gear during maintenance operations.
