## Discrepancy

THE NR 1 ENG POWER LEVER WAS DIFFICULT TO RETARD AFTER TAKEOFF FROM CLE.  THE NR 1 ENG FIRE WARNING ACTIVATED 30 SECONDS AFTER SETTING CLIMB POWER.  THE FIRE WARNING CEASED AFTER ENG POWER WAS REDUCED TO IDLE.  THE A/C WAS RETURNED TO CLE WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND SUPPLY DUCT TO NR 1 ENG NOSE COWL ANTI-ICE VALVE RUPTURED.  THE ANTI-ICE DUCT WAS REPLACED AND LEAK CHECKS WERE GOOD.  IN ADDITION, THE NR 1 ENG POWER LEVER WAS LUBRICATED.
