DURING A CLIMB TO CRUISE THE ENGINE POWER FLUCTUATED AND MAIN ROTOR RPM DECAYED TO A LEVEL INSUFFICIENT TO MAINTAIN FLIGHT. THE PILOT EXECUTED AN AUTOROTATION FROM A LOW ALTITUDE TO THE ONLY AVAILABLE AREA. DURING THE TOUCHDOWN THE RIGHT SKID WAS DAMAGED AND THE TAIL BOOM WAS SEVERED. AN FAA AIRWORTHINESS INSPECTOR EXAMINED THE ENGINE AND DRIVE TRAIN; NO DISCREPANCIES WERE DISCOVERED.
Probable Cause: THE PILOT'S FAILURE TO MAINTAIN ROTOR SPEED, DELAY OF THE FLARE, AND THE IMPROPER TOUCHDOWN. A FACTOR WAS THE LOSS OF ENGINE POWER FOR UNDETERMINED REASONS.
