Analysis

After refueling the helicopter, the pilot entered into a light hover to return to his hangar. Due to obstacles on the left side of the helicopter, the pilot attempted to hover taxi horizontally to the right. While executing this maneuver, the right skid contacted the ramp and the helicopter entered into a dynamic rollover and came to rest on its right side, which resulted in substantial damage to the main rotor. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s failure to maintain lateral control while hovering which resulted in a dynamic rollover.
