Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The pilot experienced an in flight fire after takeoff and force-landed the airplane short of the runway. The pilot performed a preflight and run up that were uneventful. As the airplane climbed through 1,000 feet, he saw a puff of white smoke. He elected to return to land and as he neared the airport, a fire erupted, and he landed in a field. At 5.4 hours prior to the accident, the number 5 cylinder was replaced. Post accident examination showed that the fuel injection line of the number 5 cylinder was disconnected at the fitting of the manifold assembly, located below the number 3 cylinder assembly. The b-nut was off the threads of the fitting and floating along the steel fuel line. The fuel line and b-nut were visually undamaged. The fuel line b-nut was reassembled to the manifold assembly without binding, and then it was tightened. No other anomalies were noted. The engine manufacturer representative stated that there are no manufacturer published torque values for the b-nut.
NTSB Probable Cause Narrative
An in-flight fire occurred during the initial climb as a result of the aviation maintenance technician's failure to sufficiently tighten the b-nut that was found disconnected post-accident. A contributing factor was the engine manufacturer's failure to specify a torque value.
