If a turbine engine catches fire when starting, what should be done initially?

When a turbine engine catches fire during starting, turning off the fuel and continuing engine rotation with the starter is an appropriate initial response because it helps to minimize further fuel flow to the combustion chamber. By stopping the fuel supply, the chances of the fire escalating are reduced. Continuing to rotate the engine with the starter can help clear unburned fuel that may be contributing to the fire and potentially assist in extinguishing it by reducing the environment suitable for combustion.

This action facilitates immediate mitigation of the fire risk and addresses the underlying cause by halting fuel introduction, which is vital in fire situations involving turbine engines. Proper training emphasizes the importance of reducing the fire hazard promptly while monitoring the situation for the need for additional measures, such as alerting emergency services or using a fire extinguisher if the fire persists and it is safe to do so.
