Unfallbericht:
A no. 2 engine power loss on climbout forced the crew to return to the airport. A massive fire in the engine nacelle was discovered after lowering the gear. The airplane departed runway 16L on emergency landing and struck ground equipment before crashing into jetways B7 and B9.

Probable Cause:

PROBABLE CAUSE: "The National Transportation Safety Board determines that the probable cause of this 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 centre 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."
