## Discrepancy

DURING CRUISE, THE NR 3 ENGINE FLAMED OUT.  APPROXIMATELY 60 SECONDS AFTER THE FLAME-OUT, THE NR 3 ENGINE FUEL ICING LIGHT ILLUMINATED.  THE COM PROCEDURE WAS FOLLOWED AND THE ENGINE WAS RESTARTED AT FL380.  THE FLIGHT CONTINUED TO NRT AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE SUMPED THE NR 3 MAIN FUEL TANK AND REPLACED THE FUEL FILTER.  NO WATER OR CONTAMINATION WAS NOTED.  THE FUEL FILTER DIFFERENTIAL PRESSURE SWITCH WAS REPLACED.
