When a hung start occurs in a turbine powerplant, what is the recommended action?

• A. Advance power lever to increase RPM
• B. Re-engage the starter
• C. Shut the engine down
• D. Abort the start and try again later

Answer: (C)

A hung start means the engine begins to rotate but never accelerates to a self-sustaining speed, leaving the core unable to take over. Continuing to feed fuel in this condition can lead to overheating, compressor stall, or other damage, so the safest, recommended action is to shut the engine down. Move the throttle to cutoff, disconnect or cut fuel, and allow the engine to coast down before inspection. After diagnosing and addressing the cause (fuel control, ignition, air supply, or mechanical faults), you can attempt another start when it’s safe.
