Engine Post Shutdown Fire: If TOT continues to rise or does not decrease after engine post shutdown fire, which action should be performed first?

• A. EMERGENCY ELECTRICAL CUTOFF; ROTOR BRAKE; EVACUATE
• B. Land/DITCH IMMEDIATELY
• C. CRANK BUTTON DEPRESS
• D. EFSL OFF; OFF

Answer: (A)

When a post-shutdown engine fire shows TOT continuing to rise, the priority is to remove sources of energy fueling the fire and then secure the rotor before evacuating. Cutting emergency electrical power immediately shuts down electrical systems and any pumps that could feed or sustain the fire, reducing heat and ignition sources. After that, applying the rotor brake locks the rotor, stopping windmilling and preventing blade movement or contact with personnel, which helps contain the fire and makes the area safer to evacuate. Finally, evacuate to get crew away from the aircraft. The other options don’t address the immediate need to cut energy sources and secure the rotor first. Depressing the crank button would re-energize parts of the system and worsen the fire. The emergency fuel shutoff lever is important, but cutting electrical power takes precedence in reducing overall energy input and potential ignition sources. A landing or ditch might be necessary later, but it isn’t the first action when TOT is still rising from a post-shutdown fire.
