The certificated commercial pilot said that he made a northerly approach to a 3,400 feet msl mountain top heliport. He said that as he approached his intended landing site, he increased collective pitch while slowing his approach airspeed, and the rotor rpm began to decay. The pilot stated that he was forced to hover over, and eventually touchdown on, an area of uneven terrain, about thirty feet short and downhill from his intended landing site. He said, in part: 'I was able to keep the toes of the skids on the uphill slope while trying to get my rpm back up. I rolled the throttle on and lowered the collective as much as I dared.' He said that in an attempt to reposition the helicopter, he increased collective pitch and applied left pedal input. The left skid impacted the ground, and the helicopter rolled over. The helicopter sustained substantial damage to the rotor system, fuselage, and tail boom. The pilot reported that weather conditions at the time of the accident consisted of clear skies, visibility unlimited, gusty winds from the southeast at 10 to 15 knots, and temperature about 70 degrees F.
Probable Cause: The pilot's failure to maintain rotor rpm, and an inadequately planned approach. A factor associated with the accident was a tailwind.
