NTSB investigators used data provided by various sources and may have traveled in support of this investigation to prepare this aircraft incident report.

After landing, while taxing back to the ramp area, the pilot observed a fire in the left engine. He secured the engine and evacuated the airplane. Examination of the engine revealed that the fuel boost pump was leaking. At the time, the pump manufacturer had a service bulletin to inspect, and retorque if necessary, four screws that secured the pump valve assembly. Examination and testing of the pump at the manufacturer's facility revealed that the wrong set of four screws had been torqued. Discussions between the pump manufacturer and airplane operator revealed that there was some ambiguity in the current service bulletin, and the maintenance personnel were confused at to which four screws the bulletin referred to. Subsequently, the pump manufacturer revised the service bulletin.

The National Transportation Safety Board determines the probable cause(s) of this incident to be:

The company maintenance personnel's failure to comply with the service bulletin, which resulted in a fuel boost pump leakage and subsequent fire during taxi. A factor was the manufacturer's confusing service bulletin.
