Aircraft Accident/Incident Report

Freeland, Washington 98249

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that while in cruise flight, he noted a minor shaking. The pilot performed a magneto check, enrichened the mixture, and switched fuel tanks. The shaking continued as the pilot noted a rise in oil temperature. The engine subsequently lost power and the pilot initiated a forced landing to a beach. The aircraft was substantially damaged during the gear up landing. During a post accident inspection of the engine it was found that the number three cylinder would not hold compression. The cylinder was removed and it was found that the piston head displayed severe pitting, heat distress and metal transfer from the piston to the cylinder wall. Portions of the piston were broken off as well as portions of the piston rings. The number five cylinder was also removed which displayed similar damage to the piston head, however not as severe. A fuel flow test of the fuel injectors found that the number three injector indicated a decreased fuel flow as compared to the other five.

NTSB Probable Cause Narrative

A partially blocked fuel injector which led to an over temperature condition in the cylinders resulting in a loss of engine power during cruise flight. Sandy terrain conditions for the landing was a factor.
