| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that, after about 20 minutes of flight in the helicopter, he returned to a private runway. The pilot descended the helicopter and began a hover-taxi from one end of the runway to the other. During the hover, the right skid contacted grass adjacent to the runway. The helicopter rolled over on its right ride, which resulted in substantial damage to the main rotor blades. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable Cause: The pilot's failure to maintain adequate clearance from terrain during a hover-taxi, which resulted in the helicopter's skid contacting grass and a subsequent dynamic roll-over.
