In an in-flight engine fire, which action should be performed first?

• A. Shut off fuel to the engine.
• B. Shout for help.
• C. Return to base.
• D. Identify the engine.

Answer: (D)

First you must identify which engine is on fire. Knowing the exact engine is essential because all follow-up actions—like shutting off fuel, isolating systems, and deploying the extinguishing agent—are targeted to that specific engine. If you proceed to isolate or extinguish without confirming the location, you could waste precious seconds, mistreat the wrong engine, or leave the actual fire source active. Use the cockpit indicators and fire warnings to verify the exact engine, then proceed to shut off fuel to that engine and isolate its systems while coordinating with the crew and, as required, deploying the fire extinguisher. The emphasis on accurate engine identification ensures the fire is contained efficiently and safely.
