Incident Overview
An experimental amateur-built airplane suffered a loss of engine power while in cruise flight. The pilot reported that fuel pressure dropped below the normal operating range. Although the aircraft's secondary fuel pump activated automatically, the fuel pressure remained below acceptable levels.
Forced Landing and Impact
The pilot executed a forced landing in a field. During the landing, the airplane struck a ditch and nosed over. The aircraft came to rest in an inverted position.
Post-Accident Inspection
Examination of the airplane revealed that it had been fueled with automotive gasoline. The pilot noted that the ambient temperature at the time of the incident was 80 degrees Fahrenheit. A post-accident engine run was conducted, but it did not reproduce the loss of engine power.
Additional Details
No further information is available regarding the aircraft's registration, engine type, or occupant status. The investigation continues.
