The commercial pilot and pilot rated passenger were practicing a pinnacle approach, terminating to a hover, over a gravel pile in the confines of a rock quarry. The commercial pilot stated that during the transition to a hover the helicopter continued to settle and the aircraft's left skid collided with the top of the pile. The pilot added full collective and left cyclic without a notable response. The helicopter continued to roll to the right and down the embankment. After the accident, the pilot reported that a dynamic roll over had occurred. Examination of the helicopter and associated system components revealed no evidence of a mechanical malfunction or failure.
Probable Cause: The pilots failure to arrest the helicopter's descent rate during a planned approach to a hover. Factors include uneven terrain.
