What happened
During a maintenance flight intended to break in a newly installed 300 horsepower Continental IO-550-D37 engine, the pilot experienced a loss of engine power. The flight was being conducted following an engine conversion that included the installation of a small 1.5-gallon fuel header tank. After the aircraft climbed to 500 feet above ground level, the engine lost power. The pilot attempted to return to the airport, but the aircraft impacted the terrain on the airport property during the forced landing. The aircraft sustained substantial damage.
Findings
- The pilot failed to place the fuel selector in the "BOTH" position prior to takeoff.
- The fuel selector had been left in the "OFF" position.
- The engine failure was caused by the pilot's failure to properly configure the fuel selector.
