| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that shortly after takeoff, the engine lost power, and during the subsequent attempt to return to the airport, the airplane collided with the terrain. A postaccident examination of the engine fuel system revealed that the fuel in the accumulator sump and the carburetor inlet screen line were contaminated with debris and water. It is likely that the loss of engine power was due to this contamination as no further evidence of a mechanical malfunction or failure that would have precluded normal operation was found.
Probable Cause: The pilot's inadequate preflight inspection of the airplane and the subsequent total loss of engine power as a result of debris and water contamination in the fuel system.
