On a post-block-out mechanical irregularity, if the QRH does not fix it, what is the recommended action?

• A. Continue to destination and address after landing.
• B. Return to the gate and write it up.
• C. Inform passengers and continue.
• D. Seek supervisor approval mid-flight.

Answer: (B)

When a mechanical irregularity remains unresolved after following the QRH, the priority is to get the aircraft inspected by maintenance on the ground. Returning to the gate allows maintenance to diagnose and repair the fault with the proper tools and parts, rather than continuing with an outstanding issue. At the same time, the defect should be written up so it’s documented in the maintenance log and can be properly dispositioned (repair, MEL dispatch, or other next steps). This approach prioritizes safety by ensuring the issue is fully addressed before the next flight.
