Incident Overview
On approach to an airport, the aircraft's engine experienced a complete loss of power. The pilot executed a forced landing into a field. No injuries were reported.
Fuel Details
The pilot reported that the airplane was equipped with a Supplemental Type Certificate allowing the use of automobile gasoline. Prior to the flight, the pilot added 15 gallons of automobile gasoline to the aircraft. He stated that he believed the gasoline was originally purchased at an automotive gas station.
Pilot Statement
The pilot expressed the belief that the fuel filter became clogged due to fuel contamination, which he suspected caused the power loss.
Aircraft and Inspection Information
The engine had accumulated approximately 2,100 operating hours since its last remanufacture, which occurred about 24 years before the accident date. An FAA inspector examined the aircraft and found no evidence of pre-impact mechanical malfunctions. The inspector observed fuel present in both fuel tanks but did not find any debris in the fuel filter.
Conclusion
The investigation did not determine a definitive cause for the engine power loss. The FAA inspector's findings contradicted the pilot's belief regarding fuel filter blockage.
