## Discrepancy

THE NR 3 ENGINE FIRE WARNING LIGHT CAME ON DURING CLIMB-OUT OF IAH.  THE ENGINE POWER WAS REDUCED AND THE LIGHT EXTINGUISHED.  WHEN POWER WAS ADVANCED THE WARNING LIGHT CAME ON AGAIN.  THE NR 3 ENGINE WAS SHUTDOWN AND THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE NR 3 ENGINE NOSE COWL ANTI-ICE DUCTING BROKEN.  THE BROKEN DUCT WAS REMOVED AND REPLACED.  LEAK CHECKS WERE GOOD.
