Incident Overview
A pilot operating under visual flight rules (VFR) on top reported that the engine experienced a loss of power. After descending through clouds, the pilot observed a field and executed a forced landing. Following touchdown, the pilot deliberately ground looped the aircraft to avoid obstructions ahead.
Post-Accident Examination
Two days after the accident, an FAA inspector examined the aircraft. The aircraft was secured, and the engine was started and found to operate normally. No determination could be made as to the reason for the loss of power.
Conclusion
The pilot's actions in performing a forced landing and subsequent ground loop prevented a collision with obstructions. Despite the engine running normally during post-accident testing, the initial power loss remains unexplained.
