Seattle - Spokane

Shortly after takeoff from Seattle-Tacoma Intl Airport, the crew noted a right engine power loss and decided to return for a precautionary landing. After lowering the landing gear, a massive fire was discovered in the right engine nacelle. After landing, directional control and all braking were lost. The aircraft departed the left side of the runway 16L after the left power lever was moved to flight idle. The f/o advised tower that the aircraft was out of control. The aircraft rolled onto the ramp area where it struck a runway designator sign, ground equipment, and jetways B7 and B9. The aircraft was subsequently destroyed by fire. Investigation revealed that during overhaul the high pressure fuel filter cover was improperly installed on the engine and the improper installation was not discovered drg company installation of the engine on the aircraft. This led to a massive fuel leak and the nacelle fire. The fire/explosion caused the loss of the engine panels, reducing the effectiveness of the fire suppression system and allowing other systems to be damaged.
