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 pilot/owner stated that he took off without performing a preflight inspection. He said he performed a run up, checked the magnetos, and did other "inside the cockpit" preparations. As he lifted off at 65 mph, he said the airplane did not immediately climb. He flew about 2/3 of the length of the runway, at an altitude of about 15 or 20 feet, and when he pitched the airplane's nose up, the engine started to sputter. He said reached forward and immediately switched the fuel selector valve from the right tank to the left tank, and the engine sputtered for another second and then ceased operating. The pilot made a forced landing to a field, and during the landing the airplane incurred damage. According to the pilot, the engine ceased operating due to the presence of water in the fuel.

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

The pilot's inadequate preflight planning/preparation, which resulted in a loss of engine power during takeoff/initial climb due to fuel contamination, that resulted in a forced landing
