## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

DURING LEVEL FLIGHT, ENGINE THROTTLE CONTROL CABLE CAME APART CAUSING THROTTLE TO BE STUCK AT 25'' MANIFOLD PRESSURE. PILOT WAS UNABLE TO DECEND WITHOUT OVERSPEEDING ENGINE AND ROTOR. PILOT APPLIED CARBURETOR HEAT AND SHUT OFF ONE MAGNETO TO REDUCE POWER AS MUCH AS POSSIBLE. PILOT SLIPPED HELICOPTER AND MADE STEEP TURNS TO REDUCE ALTITUDE. AT 150 FEET AGL PILOT TURNED OFF IGNITION AND EXECUTED AN AUTO ROTATION LANDING ON RUNWAY 9. HELICOPTER LANDED HARD CAUSING MAIN ROTOR TO CONTACT TAIL BOOM DAMAGING BOTH.
