Preflight Inspection and Engine Failure
During the pre-flight examination of the airplane, the pilot found no water in the airplane's fuel tanks. Approximately 20 seconds after takeoff, at 400 feet above ground level, the engine lost power. The pilot attempted to restart the engine but was forced to land in a rough/uneven field north of the airport.
Damage Assessment
The right wing spar was bent, and there was substantial damage to the firewall as a result of the forced landing.
Historical Fuel Contamination Issue
Three months prior to the accident, the owner detected moisture in the fuel tanks and a "drying agent" was added. The airplane was not flown between the addition of the "drying agent" and the accident.
Postaccident Examination
Postaccident examination by an FAA Inspector found water in the bottom of the carburetor.
