Probable cause

The pilot’s failure to maintain clearance from terrain. Contributing to the accident was the pilot’s encounter with low light conditions and snow-covered terrain.

NTSB narrative

The airplane rated pilot reported that he departed the airport traffic pattern with the intention of practicing helicopter maneuvers at about 200 ft. above ground level (agl) near sundown. The pilot reported that he felt a loud bang while maneuvering and realized he had “impacted the ground” without warning and the helicopter immediately rolled onto its left side. The helicopter sustained substantial damage to the fuselage and tailboom. The pilot reported that he encountered a “VFR white out” in “flat light” conditions while maneuvering over snow-covered terrain. He also reported that he was not maintaining a safe altitude. The pilot reported that he had accumulated 59.5 total flight hours in rotorcraft; however, the pilot did not possess a helicopter rating. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
