company maintenance personnel's inadequate service of the magneto system, and their failure of to replace the electric fuel boost pump, which led to a malfunctioning right magneto and an inoperative fuel boost pump.

Read the full NTSB narrative

The pilot had flown an earlier flight in the accident airplane without incident. On the second takeoff the engine lost power. Examination of the airplane revealed the right magneto was malfunctioning and the electric fuel boost pump was inoperative. Maintenance was performed on both components the day before the accident during a 50-hour inspection by company maintenance personnel. The plane had accumulated about 4 flight hours since the inspection. The airplane manufacturer indicates in the pilot operating handbook that the fuel boost pump should be replaced at engine overhaul and the engine be overhauled every 2,000 hours. The airplane had accumulated a total time in service of 3,338 hours. The maintenance records note that a major overhaul was accomplished about 1,692 hours before the accident. There was no evidence of the fuel boost pump ever being replaced. The use of the fuel boost pump is specified in the airplane emergency procedures for engine failure.
