Confidence Rating: Accident investigation report completed and information captured
The pilot reported that, while landing in a snow-covered, unimproved landing zone, the helicopter drifted rearward, the tail rotor struck a snowbank, and the helicopter began to spin to the right. The pilot reduced the throttle setting to off and applied left pedal to reduce the spin, but the helicopter drifted to the right and the right skid impacted snow. The helicopter subsequently rolled over and impacted terrain. The tailboom and the main and tail rotor drive systems were substantially damaged. 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 adequately monitor the environment which resulted in a collision with a snowbank and subsequent loss of control.
