Primary finding
Probable cause
An in-flight engine fire resulting from (1) the failure of the engine overhaul facility to install, and the failure of American Airlines to ensure installation of, the proper adapter bolt inserts to preclude fuel leakage and the failure of the engine overhaul facility to notify the aircraft operator and the engine manufacturer, and request correction, of an error in Service Bulletin (SB) 72-743; and (2) and the failure of General Electric Aircraft Engines to specify the proper adapter bolt insert and to correct SB 72-743 after notification of the error. Contributing to the severity of the incident were (1) the flight crew's failure immediately to complete the in-flight engine fire procedures and (2) the failure of Airbus Industrie and American Airlines to provide all necessary information in the in-flight engine fire procedures.
