The National Transportation Safety Board determines that the probable cause of the accident was the improper installation of the high-pressure fuel filter cover that allowed a massive fuel leak and subsequent fire to occur in the right engine nacelle. The improper installation probably occurred at the engine manufacturer; however, the failure of airline maintenance personnel to detect and correct the improper installation contributed to the accident. Also contributing to the accident was the loss of the right engine center access panels from a fuel explosion that negated the fire suppression system and allowed hydraulic line burn-through that in turn caused a total loss of airplane control on the ground.
