Preflight and Takeoff
The pilot reported conducting a thorough preflight inspection, which included checking each fuel tank twice and the fuel strainer three times for contaminants. Only a few drops of water were observed during the first sample from the fuel strainer. An engine run-up performed before takeoff showed no discrepancies. The pilot then applied full power for takeoff.
Loss of Engine Power
The airplane climbed to an altitude of approximately 150 to 200 feet above ground level. When the flight was about three-quarters down the runway, the engine experienced a total loss of power. The pilot initiated a descent for a forced landing, and the airplane collided with trees about half a mile south of the runway.
Postcrash Examination
Examination of the engine after the accident revealed water and debris contamination in the carburetor. The carburetor was bench tested, showing that the fuel flow in pounds per hour was less than the engine manufacturer's limits.
Maintenance History
Review of the engine logbook found no entry indicating that the carburetor had been overhauled since its manufacture in February 1961. The manufacturer had issued a non-mandatory service bulletin stating that the carburetor must be overhauled when the engine is overhauled or after 10 years, whichever occurs first.
