NTSB narrative
The student pilot was conducting a magneto check with a 90-degree gusty crosswind. As she raised the collective for the check, the helicopter started to wobble and then rolled over. The helicopter was parked on terrain that sloped away from the wind. The student pilot reported that she tried to move the cyclic into the wind to control the wobbling, but she had applied friction to the collective to the point that she could not move it while raising the collective for the magneto check. The FAA approved checklist called for the cyclic and collective frictions to be removed prior to the magneto check. The operator's checklist did not require the removal of the cyclic friction prior to magneto check. However, the operator reported that students were taught never to tighten the cyclic or friction to a degree that it could be moved if needed.
Probable cause
the failure of the student pilot to reduce the friction on the cyclic prior to raising the collective for the magneto check. A factor was the failure of the company to adequately define the steps in the checklist.

- 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.
