| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot had just departed the airport when the engine started to surge. Upon reducing power and leaning the mixture, the engine smoothed out and the pilot was able to turn the airplane back towards the airport. At 800 feet and parallel to runway 31, the engine quit. During the descent, the airplane clipped a tree and struck a piece of concrete before coming to rest inverted in a field. The pilot stated that the electric fuel boost pump, which was required for flight, was not turned on. A post accident inspection failed to reveal any discrepancies with the engine or the aircraft's fuel system. The pilot did not report any mechanical malfunction with the airplane. To prevent similar accident in the future, he recommended turning the electric fuel pump to the "ON" position, prior to departure. The pilot reported the ambient temperature to be 38 degrees Celsius. Item number 5 on the pretakeoff portion of the checklist notes to turn on the electric boost pump.
Probable Cause: the pilot's failure to follow the checklist and apply the electric fuel pump prior to takeoff, which resulted in vapor lock.
