Background
The pilot stated that the preflight inspection included draining fuel to check for water, and none was found. The fuel tanks were not full before the flight, and this was the first flight in approximately one month.
Accident Sequence
About five minutes after takeoff, shortly after leveling at 2,300 feet MSL, the engine lost power. Attempts to restart the engine were unsuccessful. The pilot made a forced landing on wooded terrain, during which the aircraft struck several trees before coming to a stop.
Examination Findings
Examination of the engine revealed water in the fuel injection servo unit, the fuel strainer, and the electric boost fuel pump. The left wing fuel tank, which was used during the flight, ruptured during the impact sequence. Additionally, approximately 2 ounces of water was drained from the right wing fuel tank.
