NTSB narrative
After landing the helicopter, the pilot set the cyclic and collective friction locks and left the helicopter "running" while he and his passenger disembarked the helicopter. After being left unattended for about two minutes, the helicopter began to lift-off and subsequently impacted terrain resulting in substantial damage. The pilot reported that the friction locks were still found engaged after the helicopter impacted the terrain. Winds in the vicinity of the accident were from the southeast at 21 gusting to 30 knots. According to the manufacturer, the cyclic and collective frictions are designed to allow the pilot to remove their hands from the controls to perform the cockpit portion of the preflight and post flight operations. A "caution" in the manufacturer's pilot operating handbook states, "Never leave helicopter flight controls unattended while engine is running." In addition the pilot operating handbook has a safety notice issued November 1984, which states, "Never exit helicopter with engine running. Several accidents have occurred when pilot momentarily left their helicopters unattended with the engine running and rotors turning. The collective can creep up, increasing both pitch and throttle, allowing the helicopter to lift off or roll out of control."
Probable cause
The pilot's decision to leave the helicopter unattended with the engine running in gusty wind conditions.

- 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. 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.
