## Discrepancy

THE NR 2 ENGINE A FIRE LOOP DETECTOR LIGHT BEGAN TO FLICKER WHILE IN CRUISE FLIGHT FROM LGW TO EWR.  WHEN THE NR 2 ENGINE THRUST WAS REDUCED THE FLICKERING STOPPED.  WHEN THRUST WAS ADDED THE FLICKERING RESUMED.  THE NR 2 ENGINE WAS OPERATED WITH PARTIAL THRUST, FUEL WAS DUMPED, AND THE AIRCRAFT WAS RETURNED TO LGW WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND BROKEN CLAMPS AND LOOPS A AND B WERE CHAFING.  THE NR 2 ENGINE LOWER CORE DETECTOR ASSEMBLY WAS REMOVED AND REPLACED.  THE NR 2 ENGINE FIRE DETECTION SYSTEM CHECKED GOOD.
