What are the main purpose and inspection criteria for the UH-60 landing gear?

• A. To support the aircraft on the ground and absorb landing loads; inspect for leaks, cracks, struts extended/retracted properly, tires for wear and cuts.
• B. To store cargo during ground operations.
• C. To improve fuel efficiency in flight.
• D. To house avionics equipment.

Answer: (B)

The main function of the UH-60 landing gear is to support the helicopter on the ground and absorb the loads from landings. It provides a stable footprint for taxiing and loading and must reliably bear the weight of the helicopter without collapsing or binding when you transition between flight and ground operations. When inspecting it, you look for signs that the gear can perform that role. Check for hydraulic or oleo leaks around the struts and fittings, which would indicate a loss of damping or pressure. Look for cracks, dents, corrosion, or other damage in the gear legs and attachment points, as structural failure can be catastrophic. Make sure the struts extend and retract properly and that the mechanism locks securely in both the extended (ground) and retracted (in-flight) positions. Inspect tires for wear, cuts, punctures, or ply separation and verify proper tire inflation and wheel condition. Finally, ensure gear doors, actuators, and related hardware are intact and secure, with no loose pins or damaged linkages. These functions and checks are specific to the landing gear; storing cargo, improving in-flight fuel efficiency, or housing avionics are handled by other systems and components.
