FAA Powerplant Written Practice Test

What should be done first if a turbine engine catches fire during starting?

1. Evacuate the aircraft immediately

2. Turn off the fuel and continue engine rotation with the starter

3. Activate the fire suppression system

4. Attempt to restart the engine

The correct answer is: Turn off the fuel and continue engine rotation with the starter

In the event of a turbine engine catching fire during the starting process, prioritizing the immediate reduction of fuel flow is crucial. Turning off the fuel is a critical first step as it helps to stop the source of the fire, allowing better control of the situation. Continuing engine rotation with the starter can help disperse any unburned fuel that may be left in the combustion chamber, but the primary focus is on stopping further fuel from entering the system. This action significantly reduces the potential for the fire to spread or become more intense. While activating the fire suppression system is an important part of emergency procedures, it typically comes after addressing the fuel situation. Evacuating the aircraft may not be the first priority if the situation can be managed from the cockpit, and attempting to restart the engine in the presence of a fire poses a severe risk and is generally not advised. Thus, turning off the fuel and continuing engine rotation is the most appropriate initial response in this situation.
