What is the first action to take if an engine fire occurs during the starting cycle?

• A. Discharge CO2 into the engine exhaust.
• B. Open the cowling and inspect the engine.
• C. Continue cranking the engine.
• D. Move the fuel shutoff lever to the off position.

Answer: (D)

When an engine fire occurs during starting, the first action is to shut off the fuel supply by moving the fuel shutoff lever to the OFF position. Cutting off fuel starving the fire of its energy source is the quickest way to stop the flames from propagating as you abort the start. After isolating fuel, proceed with the remaining fire-suppression steps as appropriate (such as turning off ignition and using a fire extinguisher if needed). Discharging CO2 into the exhaust, opening the cowling, or continuing to crank does not address the immediate need to remove fuel from the fire and can worsen the situation.
