Analysis

The pilot said that the airplane was climbing through 2,000 feet mean sea level when the engine lost power. He said that he conducted a forced landing in a cornfield, at which time the airplane was substantially damaged. An inspection of the airplane subsequent to the accident found material in the fuel line between the header tank and gascolator blocking the flow of fuel. The material was the consistency of sloshing compound also found in the fuel tank. No record could be found indicating when the tank was sealed with sloshing compound. The most recent annual inspection was conducted on October 19, 1998. The airplane had accumulated 32 hours time in service since that inspection.
