Why is a preflight gear inspection important?

• A. To verify gear will extend and lock, detect leaks, and identify mechanical issues before flight.
• B. Confirm only tire pressure is within normal range.
• C. Check interior cabin pressure readings.
• D. Inspect cockpit noise levels during gear retraction.

Answer: (A)

Verifying that the landing gear will extend and lock, and checking for leaks or mechanical problems before flight, is essential because the gear must function reliably for a safe approach and landing. A proper preflight gear inspection examines the hydraulic actuation system, uplocks, doors, and struts, looking for leaks, wear, cracks, or any binding that could prevent normal operation. It also confirms that warning indicators and mechanical status indications are correct so you’re alerted to any failure before takeoff. If the gear doesn’t extend and lock or if there’s a hidden hydraulic issue, you could face a gear-up landing or other gear-related failures in flight.

Focusing only on tire pressure misses the broader, critical function of the gear system. Cabin pressure readings are unrelated to gear operation, and listening for noise during retraction is not a reliable diagnostic for a preflight assessment.
