Which statement about the engine fire checklist is correct regarding fuel?

• A. Increasing fuel supply to the affected engine.
• B. Shutting off fuel supply to the affected engine.
• C. Shutting off fuel supply to the other engine.
• D. Leaving fuel unchanged.

Answer: (B)

In an engine fire, the key objective is to stop feeding the fire. Shutting off the fuel supply to the affected engine isolates the source of fuel, so even if the engine is burning, no additional fuel can reach it. This starves the fire, helping to arrest it quickly and making it easier to extinguish with the fire suppression system.

Shutting off fuel to the other engine would deprive the aircraft of thrust and isn’t part of extinguishing the fire on the burning engine. Leaving the fuel unchanged leaves the fire fed and can allow it to continue spreading or intensifying. Increasing the fuel supply would feed the fire and make the situation worse.

So, the best action is to cut the fuel to the engine that’s on fire, while other procedures for fire suppression are carried out as needed.
