The pilot was on a familiarization flight of a new helicopter. He had successfully completed hovering, several takeoffs and landings, and two hovering autorotations. He had to discontinue his maneuvers in the traffic pattern due to traffic, so he requested to use the pad near the plant. During a hovering autorotation at 5 feet AGL, the helicopter suddenly drifted to the left. Despite his efforts correcting with right cyclic, the helicopter continued to roll to the left. It touched down on the left main landing gear, followed by the nosewheel, and came to rest on its left side. Of the 12 hours the helicopter had accumulated, the pilot had 9 hours in this make and model. Examination of the wreckage did not disclose any evidence of mechanical malfunction with the helicopter or engine, and the pilot did not report any.
Probable Cause: The pilot's failure to maintain control during autorotation, which resulted in an unleveled attitude touchdown, roll over, and collision with the ground.
