| Confidence Rating: |  Accident investigation report completed and information captured |
The airplane, which was owned and operated by the private pilot, experienced a total loss of engine power shortly after takeoff, descended, and impacted a field. A fire erupted that consumed the majority of the airplane's cabin and the inboard sections of both wings. The wreckage distribution, ground scars, and crushing of the wing leading edges were indicative of a low-speed nose-down impact and consistent with an aerodynamic stall. Examination of the fuel system revealed the presence of rust and water in both electric fuel pumps and water in the engine carburetor bowl. The examination revealed no other engine or airframe anomalies that would have precluded normal operation. The rust found in the fuel pumps indicated that the fuel system had been contaminated with water for a long period of time. The airplane owner's handbook provided clear and explicit instructions on how to check before flight for fuel system contamination.
Probable Cause: The pilot's failure to maintain control of the airplane following a loss of engine power during initial climb after takeoff, which resulted in the wing's critical angle-of-attack being exceeded and a subsequent aerodynamic stall. Also causal was the pilot's inadequate preflight inspection of the airplane's fuel system, which resulted in the loss of engine power due to water contamination.
