DURING CRUISE FLIGHT THE ENGINE BEGAN TO RUN ROUGH AND THE PILOT OBSERVED THE CARBERATOR TEMPERATURE GUAGE INDICATING CAUTIONARY ZONE. HE APPLIED CABURETOR HEAT AND THE ENGINE LOST POWER. AFTER THE LOSS OF ENGINE POWER THE PILOT ENTERED AN AUTOROTATION INTO THE WIND; HOWEVER, HE NOTICED POWER LINES AND WAS FORCED TO TURN TO AVOID THEM. THE NEW HEADING CAUSED THE HELICOPTER TO LAND WITH A QUATERING TAIL WIND. AS THE HELICOPTER REACHED 10 FEET ABOVE THE GROUND IT LOST MAIN ROTOR RPM AND LANDED HARD. DURING THE LANDING SEQUENCE THE HELICOPTER BOUNCED AND THE MAIN ROTOR BLADES STRUCK THE TAIL BOOM.
Probable Cause: THE PILOT'S FAILURE TO MAINTAIN MAIN ROTOR RPM. THE WEATHER CONDITIONS AND DELAYED APPLICATION OF CARBURETOR WERE FACTORS IN THE ACCIDENT.
