Location:Trading Bay, AK -   United States of America

Investigating agency: NTSB
Narrative:
The pilot was landing at an off-airport site in flat-light conditions. After touchdown, the left skid sank into the snow, and the helicopter began rolling to the left. The pilot attempted to correct the roll with right cyclic input but overcorrected, and the helicopter entered a dynamic roll to the right. The helicopter came to rest on its right side, sustaining substantial damage to the tailboom and the main rotor drive system. The pilot stated that there were no preaccident mechanical anomalies with the helicopter.
Probable Cause: The pilot's selection of an unsuitable landing site in flat-light conditions, which resulted in an inadvertent dynamic rollover.
