## Discrepancy

EN ROUTE NR 2 ENG FIRE INDICATION.  ENG SHUTDOWN & ACFT DIVERTED.  DUMPED FUEL & LANDED UNDER AMBER ALERT.  ENG INSPECTED FOR EVIDENCE OF FIRE & OVERHEAT CONDITIONS, NONE FOUND.  FIRE WARN SYS TEST PASSED.  NO MX MESSAGE FAULTS RECORDED.  THE HIGH POWER ENG RUN AT BGR & SUBSEQUENT FERRY FLIGHT BACK TO ORD, DID NOT DUPLICATE THE FIRE INDICATION.  THE ITEMS REMOVED AS PRECAUTIONARY:  FODC CARD, DUCT VENT VALVE (ALTHOUGH, GASKET WAS FOUND DAMAGED), & UPPER FIRE LOOP HAVE ALL CHECKED OK PER SHOP.  THE A/C WAS INSPECTED FOR FIRE WARNING WIRE INTERFERENCE DESCRIBED ON 777-SL-24-032.  THE A/C CHECKED OUT CLEAN.  QAR & FDR INFORMATION HAS BEEN COMPILED & WILL BE FWD'D TO BOEING FOR ANALYSIS.
