NTSB narrative
The flight instructor reported that during an instructional flight, he and his student were approaching a ridge line to conduct a practice pinnacle landing. The student pilot stated that as they were over the ridge line, the helicopter was struck by a wind gust, and it yawed to the right. He added left anti-torque pedal to correct the yaw, then the low RPM horn sounded, and the instructor took the flight controls. He lowered the collective and added forward cyclic to move away from terrain, however the helicopter landed hard in the snow and rolled onto its right side. The tail boom was substantially damaged. The instructor reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain aircraft control during a pinnacle landing that resulted in a hard landing and subsequent roll over.

- 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, 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.
