NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane sat on the ramp for about 2 1/2 weeks with the fuel tanks half filled. Outside air temperature had dipped to 18 degrees Fahrenheit the previous night, and was still below freezing about 3 hours before the accident. Temperature at the time of the accident was 43 degrees Fahrenheit. The pilot did not check the fuel for water prior to the accident flight. After a normal start, run-up, and takeoff, the engine failed at 400 to 500 feet in the air, and the pilot made a forced landing. Evidence of water was subsequently found in a container that held fuel removed from the airplane.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

Water/ice in the fuel system and the pilot's inadequate preflight inspection.
