Douthitt Strip Airport
Aircraft Accident/Incident Report

El Centro, California 92243
Monday, August 28, 2006 10:06 PDT

NTSB Narrative Summary Released at Completion of Accident

The engine lost partial power on takeoff and the pilot force-landed the airplane in a field. The airplane was involved in a similar accident 2 years prior. After being rebuilt, the pilot (who was also the aviation maintenance technician who rebuilt it) was relocating the airplane to a nearby airport. Post accident examination and testing of the fuel selector showed that the detent ring was bent and the air bypassed internally between the ports. With the detent ring bent, positive engagement of the fuel selector's position was difficult to ascertain. In addition, the shaft was worn. The type certificate holder for the airplane had released two Service Bulletins to replace the aging valves. In addition, the Federal Aviation Administration issued a Special Airworthiness Information Bulletin recommending aircraft owners test the valves for internal leakage and condition, and if necessary, replace them.

NTSB Probable Cause Narrative

The partial loss of engine power during takeoff, as a result of air being sucked into the fuel system due to a worn fuel selector valve stem and a bent detent ring.
