## Discrepancy

SMOKE ENTERED CABIN WHILE EN ROUTE.  THE NR 3 PNEUMATIC SUPPLY AND NR 3 AIR CONDITIONING PACK WERE SHUTDOWN IAW CHECKLIST AND THE SMOKE CEASED.  THE FLIGHT CONTINUED TO IAH WITHOUT FURTHER PROBLEM.  MAINTENANCE REPLACED THE NR 3 PACK COALESCER BAG.  THE PACK WAS RUN WHILE OPERATING THE NR 3 ENGINE AND APU AND OPERATION CHECKED GOOD WITH NO SMOKE NOTED.  THE AIRCRAFT COMPLETED FIVE FLIGHTS WITHOUT REPORTS OF CABIN SMOKE SINCE THIS CORRECTIVE ACTION WAS IMPLEMENTED.
