NTSB Narrative Summary Released at Completion of Accident

According to the pilot, after about 30-minutes of flight he felt a slight shudder in the engine which lasted for about three seconds. The engine did not lose any power and all instruments remained in the green. About 5-minutes later, with no indication or warning, the engine immediately stopped and the propeller wind milled. During the forced landing the airplane struck a power line, and landed hard on the main landing gear. Examination of the engine found the carburetor broken at its attach point on the intake manifold on the bottom of the engine. The carburetor was removed and disassembled. Examination of the carburetor float bowl found reddish/brown particles resting in the bottom of the float bowl. Additionally, flakes of the reddish/brown particles were found clogging the carburetor jet pickup. A replacement carburetor was installed on the engine and the engine was started and was run up to 1500 revolutions per minute. The engine ran for about five-minutes before being shutdown with the mixture control.

NTSB Probable Cause Narrative

Loss of engine power due to fuel system contamination.
