According to the pilot, he made a go-around after his first approach due to traffic in the area. He forgot to switch fuel tanks while dealing with the traffic situation and as the airplane turned crosswind, the engine “started to sputter and then it stopped.” The pilot switched fuel tanks and attempted to restart but was unsuccessful. He did not have enough altitude or time to get the engine restarted and decided to ditch in a lake to avoid a housing area. A post-accident inspection by a Federal Aviation Administration inspector revealed that the airplane incurred substantial damage to the left wing and fuselage and that no mechanical anomalies existed before the accident. The pilot stated, “It was simply fuel starvation.”
