Engine Post Shutdown Fire: If high TOT still evident after 10 seconds, what action?

• A. CRANK BUTTON DEPRESS
• B. Emergency Electrical Cutoff
• C. Rotor Brake
• D. Evacuate

Answer: (A)

When a turbine engine shows high turbine outlet temperature after a shutdown, it suggests heat and potentially a fire inside the engine core. The recommended action is to depress the crank button to re-crank the engine. This brief starter cycle spins the compressor and moves air through the engine, helping purge residual fuel and flames, cooling the core and allowing the fire to burn off or be fed less fuel. The other options don’t directly tackle the fire: cutting electrical power doesn’t address the engine fire, applying the rotor brake won’t affect the fire in the engine, and evacuating is reserved for scenarios where the fire cannot be controlled. If the temperature remains high after the purge attempt, follow the remaining fire suppression procedures.
