Confidence Rating: Accident investigation report completed and information captured
The pilot stated that, about 30 minutes after departure and while in cruise flight at an altitude of about 10,500 ft mean sea level, he observed the fuel pressure decrease from 44 to 39 pounds per square inch (psi), increase to 40 psi, and decreased to 0 psi as the engine speed decreased to 0 rpm. For about the next 3 to 5 minutes, the fuel pressure and RPMs fluctuated between normal and zero. He activated the backup fuel pump with no effect noted. The airplane sustained substantial damage to both wings during the forced landing.

A postaccident examination revealed no mechanical malfunctions or anomalies that would have precluded normal operation. Engine runs were performed with no anomalies noted that were consistent with the pilot's statements and onboard recorded data. The onboard recorded data showed fluctuations in fuel pressure and intermittent operation of the engine consistent with the pilot's statement. As a result, the reason for the partial loss of engine power could not be determined based on the available evidence for this investigation.

Probable Cause: A partial loss of engine power for reasons that could not be determined based on the available evidence.
