## Discrepancy

THE NR 2 ENGINE FIRE WARNING LIGHT FOR B-LOOP (A LOOP WAS ON PLACARD) ILLUMINATED TEN MINUTES AFTER TAKEOFF.  THE NR 2 ENGINE WAS SHUT DOWN, BOTH FIRE BOTTLES WERE DISCHARGED AND THE AIRCRAFT WAS RETURNED TO LGW WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND NO EVIDENCE OF FIRE.  MAINTENANCE FOUND BOTH A AND B FIRE LOOPS CHAFED THROUGH.  BOTH LOOPS WERE REMOVED AND REPLACED.  IN ADDITION, BOTH FIRE BOTTLES WERE REPLACED.
