Accident
The aircraft was being ferried from Walterboro to Charleston, South Carolina, after a period of non-use of about two years, during which it had been flown only once. Following takeoff and two circles in the vicinity of the departure airport, the pilot set course for Charleston at an altitude of approximately 1,000 feet. Shortly thereafter, the left engine began to surge and lose power, followed by the right engine. In an attempt to reach an open field beyond a tree line, the aircraft stalled and crashed. All three crew members were uninjured, but the aircraft sustained damage beyond repair.
Investigation
Examination of the wreckage revealed water contamination throughout the fuel system. Evidence of water was found in the left main fuel feed line and the cylinders of the left engine. The right carburetor screen was excessively corroded, and a fuel sample showed pronounced evidence of water. Water was also present in the cylinders of the right engine. The left and right fuel selector valve screens had not been pulled and cleaned, and water was found in both screens. The refueling facility from which the aircraft had been refueled was inspected for water, but none was found.
Probable Cause
The official investigation determined that water contamination of the fuel system caused the power failure. Additionally, preparation of the aircraft for the flight after a prolonged period of non-use was inadequate.
