During starting of a turbine powerplant using a compressed air starter, a hung start occurred. Select the proper procedure:

• A. Advance power lever to increase RPM
• B. Re-engage the starter
• C. Shut the engine down
• D. Wait and re-check

Answer: (C)

A hung start happens when the starter and ignition are present, but the engine won’t accelerate to the speed needed for stable operation. In this situation, continuing to fight the start can allow fuel to be burned without the rotor turning up properly, which risks overheating, compressor surge, or mechanical damage. The safest course is to shut the engine down, secure the fuel and air sources, and troubleshoot the underlying cause (such as a fuel-control fault, air supply issue, or a mechanical problem). Re-engaging the starter, waiting and re-checking, or advancing the power lever while the engine is hung can all lead to further damage; shutting down promptly is the prudent way to prevent harm and allow a proper inspection before attempting another start.
