## Discrepancy

DURING DESCENT, THE CREW RECEIVED A 14 TH STAGE DUCT MESSAGE.  THE QRH WAS COMPLIED WITH AND THE THRUST LEVER WAS REDUCED TO IDLE AT WHICH TIME THE MESSAGE EXTINGUISHED.  AN EMERGENCY WAS DECLARED AND THE AIRCRAFT LANDED SAFELY.  MAINTENANCE REMOVED AND REPLACED THE LT BLEED LEAK CONTROL UNIT.  ENGINE RUNS AND OPS CHECK GOOD.  AIRCRAFT OK FOR SERVICE.
