## Discrepancy

THE NR 1 ENGINE FIRE WARNING LIGHT ILLUMINATED WHILE EN ROUTE.  THE THROTTLE WAS RETARDED AND THE LIGHT EXTINGUISHED, THE LIGHT CAME BACK ON DURING APPROACH TO CLE.  THE NR 1 ENGINE WAS SHUT DOWN AND THE FIRE BOTTLE WAS DISCHARGED AS A PRECAUTIONARY MEASURE.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  TWO LOOP CONNECTORS ON LOWER A-LOOP OF NR 1 ENGINE WERE FOUND AT FAULT.  THE LOOP CONNECTORS WERE REMOVED AND REPLACED.  IN ADDITION, THE FIRE DETECTION UNIT AND A AND B LOOP SWITCHES WERE REPLACED AS A PRECAUTIONARY MEASURE.  ALSO, THE FIRE BOTTLE WAS REPLACED.  THE FIRE DETECTION SYSTEM TESTED NORMALLY.
