Overview
A private pilot was returning from a business flight when the engine quit during the approach to landing. The pilot executed an emergency landing in an open field.
Sequence of Events
During the landing approach, the pilot reported that the engine lost power. The emergency landing was made in an open field. After touchdown, the right wing struck a sign. The aircraft then skidded to rest across a paved road and into another open field.
Investigation
A post-accident investigation revealed fuel in both fuel tanks, though the exact quantity could not be determined. An engine run conducted after the accident did not reveal any evidence that could explain the reported engine failure.
Findings
The investigation was unable to identify a mechanical or fuel-related cause for the engine failure. No evidence of a preexisting defect or malfunction was found. The fuel system appeared to contain fuel, but the quantity was not sufficient to confirm a fuel starvation scenario.
