Incident Summary
A pilot discovered water in the left wing fuel tank during a preflight inspection. After obtaining a second sample, the fuel appeared clear, and the pilot considered the contamination eliminated. An engine run-up before takeoff showed no discrepancies. The flight departed normally, but while on the downwind leg, the engine began to sputter. The pilot turned base and then onto short final with flaps fully extended. Concerned about landing long, the pilot applied full power for a go-around; the engine responded. During a climb with incremental flap retraction, at approximately 300 feet above ground level, the engine ceased operation.
The pilot initiated a descent for a forced landing toward an open field. After recognizing an inability to land there, the pilot continued the descent, colliding with a power line, a house, and the ground.
Postaccident Findings
An FAA inspector examined the aircraft after the accident. The gascolator and carburetor contained water, with approximately 110 milliliters drained from the carburetor bowl. Both wing fuel cap seals appeared serviceable. Testing of the water drained from the carburetor revealed the presence of free chlorine and sodium chloride.
