Investigator assessment
Analysis narrative
The pilot reported that the purpose of the flight was to relocate the helicopter to a hangar at a nearby airport before a winter storm impacted the area. The pilot took off in moderate visual meteorological conditions and moderate rain; but as the helicopter neared the airport, the precipitation turned from rain to snow. The pilot turned final about 1 mile north of the airport when the precipitation increased, and the visibility reduced. The helicopter impacted terrain about 200 yards north of the runway surface in a mostly level attitude before it rolled onto its left side. The fuselage was substantially damaged. The pilot reported that there were no preaccident no mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
