Accident Details
Approximately 15 minutes after takeoff, the engine lost power while the aircraft was on the downwind leg for a landing on a private strip. Subsequently, the aircraft struck the tops of two trees, crashed, and came to rest approximately 100 yards south of the runway.
Investigation Findings
An examination of the wreckage did not reveal any preimpact mechanical failures. The upper wing fuel tank was empty. The fuselage fuel tank was damaged during impact, and fuel from it spilled onto the pilot's clothes and body. The wing fuel tank selector was found in the OFF position, while the fuselage tank valve was in the ON position.
The engine was partially disassembled, but no preimpact mechanical malfunction was noted. Contaminants were noted in the fuel strainer. Some yellowish colored fuel was removed from the carburetor, which also contained some contaminants.
