If a turbine engine catches fire during starting, what is the recommended initial action?

Turn off fuel and continue engine rotation with the starter.

When a turbine engine catches fire during start, the priority is to stop the fire by removing its fuel source. Cutting off the fuel prevents the flame from drawing more energy and keeps the fire from growing. After shutting off the fuel, continuing to rotate with the starter helps windmill the engine’s compressor. This keeps the engine moving so hot spots don’t build up, aids in cooling, and reduces the chance of damage as the fire is contained.

Letting the fire burn unchecked, trying to restart while the fire is burning, or stopping rotation immediately without first cutting fuel would either feed the fire or fail to address the flame and cooling needs.

Turn off the fuel and let the engine burn out.

Keep rotating and attempt to start again.

Withdraw the starter and abort.
