NTSB narrative
The helicopter took off approximately 100 pounds over maximum gross weight, then flew for an hour and a half conducting low altitude power line inspections. A hand-held Global Positioning System receiver located near the wreckage recorded the entire flight. A review of the last 23 seconds of recorded data revealed that the helicopter was headed 088 degrees, before it initiated a left turn to a heading of 285 degrees. During that time, the helicopter decelerated from a ground speed of 30.4 knots to 3.6 knots before the data ended. The helicopter descended vertically through trees, and came to rest on its right side. The collective was found in the full-up position. Examination of the low rotor RPM light displayed significant stretching and deformation to the filament, consistent with a hot impact. The Robinson R-22 Beta Pilot Operating Handbook (POH) Safety Notice #SN-10, stated that a primary cause of fatal accidents in light helicopters is failure to maintain rotor RPM. The 417-hour helicopter pilot was reported to have accumulated a total of 370 hours in R-22 helicopters.
Probable cause
The pilot's failure to maintain adequate main rotor rpm while maneuvering at a low altitude.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
