After block out, what is the prescribed action if a mechanical irregularity is discovered?

• A. Follow the QRH and continue to destination if it fixes it.
• B. Follow the QRH. If that fixes it you can continue and write it up when you land. If the QRH doesn't fix it you go back to the gate and write it up.
• C. Return to the gate immediately and write it up.
• D. Continue to destination and address the issue later.

Answer: (B)

When a mechanical irregularity is found after block out, the first, and correct, action is to follow the QRH and apply the prescribed abnormal procedures. The QRH lays out the exact steps to determine whether the issue can be managed safely in flight. If those steps resolve the problem, you may continue to the destination, and you should document the event with a write-up at or after landing. If the QRH steps do not resolve the issue, you must return to the gate so maintenance can inspect and fix it, with a proper maintenance report completed. This approach keeps the flight safe and ensures the problem is properly addressed and recorded.
