Probable cause

The loss of control of the helicopter during taxi, which resulted in rollover.

NTSB analysis

The pilot of the helicopter was practicing some maneuvers in the vicinity of his local airport. Upon completion of these maneuvers, while taxiing towards his hangar, the pilot reported that the helicopter began to yaw to the right. The pilot described that he was about a 1 ft above and that once one of the helicopter’s skids contacted the ground, he was unable to regain control and the helicopter rolled over. The helicopter’s fuselage, main rotor blades, and tailboom were substantially damaged. The pilot reported that there were no pre-accident mechanical malfunctions or failures with the helicopter that would have precluded normal operation, nor were any discovered during a postaccident examination of the helicopter by a Federal Aviation Administration inspector.
