NTSB narrative
On January 16, 2026, about 1130 central standard time, a Cessna 172 airplane, N79118, was substantially damaged when it was involved in an accident near Amery, Wisconsin. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 maintenance test flight. The pilot reported that during a post-maintenance test flight, he heard and felt a bang followed by violent shaking of the airframe with partial loss of engine power. The airplane was circling over Amery Municipal Airport, Amery, Wisconsin, and subsequently the pilot chose to reenter the traffic pattern for runway 36. As the airplane turned onto the base leg for runway 36, total engine power was lost. The pilot realized he would not make the runway and elected to perform a forced off-field landing in a snow-covered field. During the rollout in the snow, the airplane nosed over which resulted in substantial damage to the fuselage, and both wings. Prior to the flight, the Lycoming O-320-E20 reciprocating engine had a complete overhaul and was reinstalled onto the airplane. The mechanic reported that there were no issues with the engine observed during the ground testing before the maintenance flight. The airplane was retained for further examination.

- 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.
