THE ACFT DEPARTED THE LEFT SIDE OF THE RWY 16L AFTER THE LEFT POWER LEVER WAS MOVED TO FLT IDLE. THE F/O ADVISED TWR THAT THE ACFT WAS OUT OF CONTROL. THE ACFT ROLLED ONTO THE RAMP AREA WHERE IT STRUCK A RWY DESIGNATOR SIGN, GROUND EQUIPMENT, AND JETWAYS B7 AND B9. THE ACFT WAS SUBSEQUENTLY DESTROYED BY FIRE. INVESTIGATION REVEALED THAT DURING OVERHAUL THE HIGH PRESSURE FUEL FILTER COVER WAS IMPROPERLY INSTALLED ON THE ENG AND THE IMPROPER INSTALLATION WAS NOT DISCOVERED DRG COMPANY INSTALLATION OF THE ENG ON THE ACFT.
