For a start malfunction on the ground, what is the recommended action to stop the engine?

• A. LP STOP
• B. Increase throttle to max
• C. Ignition OFF
• D. Fuel shutoff

Answer: (A)

When a start malfunction on the ground occurs, the priority is to stop fuel delivery to the engine as quickly as possible so a hung start or abnormal operation doesn’t continue. LP STOP is the action that immediately terminates fuel supply within the low-pressure start circuit, causing the engine to shut down promptly and safely. This direct, rapid fuel shutdown is preferred over simply advancing power, which would push more fuel into a problematic start and could worsen the situation. Ignition OFF alone may not cut fuel and might not stop an engine that’s already lit or auto-igniting, and a general fuel shutoff tap can take longer or require additional steps. LP STOP is the designed, quickest way to halt an engine during a problematic start on the ground, making it the best choice.
