What is the proper procedure for inspecting landing gear and tires?

• A. Check tire color and tread depth using a nonstandard gauge.
• B. Verify gear doors closure after testing tire inflation.
• C. Test brake pad wear for landing gear performance.
• D. Check tire condition and inflation, tread, leaks; verify strut extension and retraction and gear doors closure.

Answer: (D)

The main idea being tested is performing a complete preflight check of the landing gear and tires by assessing both the tire condition and the gear mechanism. You verify tire condition, inflation, tread, and leaks to ensure the tires are within limits and free from damage that could cause failures in flight. You also test the hydraulic struts by extending and retracting the gear to confirm smooth operation and check for leaks or abnormal movement. Finally, you ensure the gear doors close properly after retraction to maintain aerodynamics and prevent interference or damage. This combined check ensures both the tires and the landing gear system are ready for safe operation. Options that focus only on one aspect or use nonstandard methods fall short: they don't address all the essential elements—tire condition, proper inflation, tread, leaks, strut operation, and door closure—together.
