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.

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.
