Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

According to the pilot, he made a go-around after his first approach due to the aircraft traffic in the area. In diverting his attention to monitoring the traffic, he forgot to switch the fuel tank selection. As the airplane turned onto the crosswind leg of the traffic pattern, the engine began to sputter and subsequently experienced a total loss of power. The pilot switched to the other fuel tank in an attempted to restart the engine, but was unsuccessful. With the airplane's altitude decreasing, he decided to ditch in a lake to avoid a housing area. A postaccident inspection by a Federal Aviation Administration inspector revealed that the airplane incurred substantial damage to the left wing and fuselage; they found no evidence of preimpact mechanical anomalies. The pilot opined that the engine had a loss of power due to fuel starvation.

Factual narrative

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.”
