What is the required sequence of actions before dispatch when a fuel leak is suspected preflight?

• A. Ground stop, secure fuel source, isolate affected area, notify maintenance, and do not dispatch until cleared.
• B. Proceed with flight while monitoring fuel levels.
• C. Ignore leak if smell is faint.
• D. Refuel with the airplane still connected.

Answer: (A)

When a fuel leak is suspected before dispatch, the primary goal is to prevent any fire hazard and ensure the aircraft is truly airworthy before leaving the ground. Start by placing the flight on a ground stop so no departure occurs until the issue is assessed. Then secure the fuel source to stop any further leakage and prevent fuel from continuing to escape. Next, isolate the affected area to limit exposure, keep people away from the leak, and eliminate ignition sources nearby. Alert maintenance so trained personnel can inspect, diagnose, and repair the leak, and document the condition. Finally, do not dispatch until maintenance clears the aircraft as safe to fly. This sequence ensures containment, proper diagnostic follow-through, and a legitimate airworthiness determination before any flight.
