Probable cause

A total loss of engine power for reasons that could not be determined based on the available information.

NTSB narrative

After reaching 12,500 ft altitude, the private pilot attempted to adjust the boost control of the experimental amateur-built airplane's engine. When he did so, the engine experienced a total loss of power. The pilot subsequently performed a forced landing to a field. A postaccident examination of the engine revealed no anomalies. The examination revealed that the airplane was powered by an aircraft engine that was modified to employ a belt-driven automotive centrifugal supercharger. Due to the experimental nature of the supercharger installation, no determination could be made regarding its installation or operation; however, no outward signs of a failure or malfunction were observed. Based on the available evidence, the reason for the loss of engine power could not be determined.
