NTSB narrative
The pilot/owner reported that, after completing several aerobatic maneuvers, he and the flight instructor were returning to the departure airport when the engine began to lose power. The pilot made several attempts to regain engine power but was unsuccessful, and he then asked the flight instructor to fly the airplane. The flight instructor set the airplane for best glide and made a forced landing in a freshly plowed open field. During the landing on soft terrain, the main landing gear sank into the ground, and the airplane nosed over. The engine ran normally during an engine test run, and postaccident examination of the engine revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
A loss of engine power during cruise flight for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded normal operation.

- 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.
