## Discrepancy

ON DESCENT TO MSP, THE NR 2 ENGINE FIRE WARNING SYSTEM ACTIVATED MOMENTARILY.  A PRECAUTIONARY SHUTDOWN WAS ACCOMPLISHED ON NR 2 ENGINE.  THE FLIGHT CONTINUED TO MSP AND LANDED WITHOUT FURTHER INCIDENT.  A LEAK WAS FOUND IN THE NR 3 START BLEED AIR DUCT.  MAINTENANCE REPLACED THE DUCT AND CHECKED THE SYSTEM FOR LEAKS, NONE FOUND.  OPERATIONAL CHECKS WERE OK, AIRCRAFT RETURNED TO SERVICE.
