For an engine post-shutdown fire response, what is the pilot’s first attempt to extinguish the fire?

For an engine post-shutdown fire response, the pilot's first attempt to extinguish the fire typically involves windmilling the engine. This action involves allowing the blades of the engine to rotate freely, which can generate airflow that helps to extinguish any flames or reduce the intensity of the fire. The windmilling effect can introduce fresh air into the combustion area, which might assist in cooling down the fire and potentially causing it to go out.

This approach is often preferred as an initial line of defense because it utilizes the engine's natural movement rather than relying on a chemical agent or external intervention, which may come later in the fire response sequence. The immediate focus in such scenarios is to address the fire effectively without compromising safety or delaying necessary emergency procedures. Following the windmilling attempt, the pilot can evaluate the situation further and decide if additional measures, such as using extinguishing agents, are required.
