Analysis

The pilot had purchased the airplane that day and was preparing for a local flight with his son. All ground checks were normal. Shortly after takeoff, he observed a decrease in engine RPM. He switched fuel tanks, and checked the mags, carb heat, and mixture. With trees ahead, he turned the airplane and forced landed in an adjacent field. The airplane came to a stop, and was consumed by fire. Teardown inspection of the engine did not reveal any evidence of malfunction or failure. The pilot reported that he had sufficient fuel for the flight. The mags, carburetor, and engine driven fuel pump were destroyed by fire. Fire damage prevented any testing of the aircraft fuel. The reason for the engine power loss could not be determined.
