## Discrepancy

THE NR 3 ENGINE A-FIRELOOP WARNING LIGHT ILLUMINATED DURING CLIMBOUT.  A FIRE TEST WAS PERFORMED PER CHECKLIST AND THE B-LOOP TESTED GOOD.  THE A-SYSTEM HAD A HISTORY OF FIRE WARNINGS.  THE FLIGHT WAS CONTINUED USING B-LOOP ONLY.  THE AIRCRAFT LANDED AT EWR WITHOUT FURTHER WARNINGS.  MAINTENANCE FOUND THE FORWARD FAN FIRE DETECTION LOOP PINCHED.  THE FORWARD FAN FIRE DETECTION LOOPS A AND B WERE REMOVED AND REPLACED, OPERATIONAL CHECKS WERE GOOD.
