Cessna 421B Golden Eagle II

Shortly after takeoff, the aircraft was seen flying low over trees, followed by a rapid roll to the left and a collision with wooded terrain. One witness reported seeing gray smoke trailing the left engine before the crash. An inspection of the wreckage revealed the left engine spark plugs were black and heavily sooted. Neither propeller had been feathered before the accident. The landing gear was found in an extended position. Further investigation revealed that Cessna multi-engine service bulletin (SB) 88-3 was not complied with. This SB modified the fuel system to provide for direct pilot (rather than automatic) actuation of the output pressure of the auxiliary fuel pumps. Both engines ran satisfactorily on a test stand following the accident. No other evidence of mechanical failure or malfunction was found. All three occupants were killed.
