## Discrepancy

DURING CLIMB ENGINE FIRE INDICATION FOR THE NR 1 ENGINE ENUNCIATED.  FLIGHT CREW COMPLIED WITH COM, FIRE EXTINGUISHER WAS ACTIVATED AND THE NR 1 ENGINE WAS SHUT DOWN.  FLIGHT CREW RETURNED AIRCRAFT TO DEPARTURE AIRPORT PERFORMING AN UNEVENTFUL LANDING.  MAINTENANCE FOUND A RUPTURED 13TH STAGE FUEL DE-ICE DUCT/AIR MANIFOLD AND REPLACED IT.
