The pilot told the NTSB investigator-in-charge (IIC) during a telephone interview, and in his NTSB Pilot/Operator report, the airplane had been parked in the rain for two days with the fuel tanks about 1/3 full. About 10 minutes after takeoff, while in cruise at 300 feet above the ground, the engine momentarily ran rough. He said he applied carburetor heat, adjusted the throttle, and the engine smoothed out. About 10 minutes later the engine suddenly lost power. The pilot landed the airplane on tundra, and it nosed over. The pilot told the IIC that he suspected water contamination in the fuel.
Probable Cause: The inadequate preflight by the pilot, which failed to detect water contamination of the airplane's fuel.
