NTSB narrative
The private pilot reported that, about 10 minutes after departing for a personal, local flight and when the airplane was about 1,000 ft above ground level, the engine began running roughly, and the rpm surged several times despite the engine monitoring gauges all indicating normal operation. The pilot chose to make a precautionary landing on a snow-covered dirt airstrip. The pilot reported that, after reducing power to land, he did not recall the engine experiencing further roughness or surging. During the landing roll, the airplane nosed over in the deep snow and then came to rest inverted.
During postaccident test runs, the engine ran normally through various power settings with no anomalies noted that would have precluded normal operation. The reason for the engine momentarily running roughly and surging could not be determined.
Probable cause
An engine anomaly for reasons that could not be determined, which resulted in a precautionary landing in deep snow and a subsequent noseover.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2017-01-28.
