## Discrepancy

LGA - FLT NR 0329 - DURING CLIMB, FLIGHT EXPERIENCED A RAPID DECOMPRESSION. AN EMERGENCY WAS DECLARED AND A DESCENT WAS MADE TO 10,000 FEET.  CABIN PRESSURE DID NOT RAISE ABOVE 14,000 FEET PRE-EMPTING THE OXYGEN MASKS TO DEPLOY.  THE FLIGHT DIVERTED TO LGA AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE DUCT ASSEMBLY ON THE RIGHT PACK.  OPERATIONS CHECKED GOOD.  (M)
