NTSB narrative
The pilot of the helicopter reported that, while flying in mountainous terrain, he decided to land on top of a ridge for a rest break. The pilot performed a circling reconnaissance of the area before he began his descent to his intended landing spot. During the descent, the pilot felt a wind gust from behind, then the rotor rpm began to decay, and the low rotor rpm light illuminated along with the aural warning horn. The pilot attempted to reestablish power without success as the helicopter continued to descend. To avoid going over the ridge, the pilot intentionally lowered the helicopter to the ground and rolled the helicopter onto its right side. The helicopter sustained substantial damage to the fuselage and tail boom. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain adequate rotor rpm while descending with a gusting tailwind condition, which resulted in a loss of helicopter control.

Source notes (4)
- 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, cause areas. 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.
