## Discrepancy

CREW REPORTED THAT DURING CLIMB RECEIVED A PACK 2 VALVE CLOSED MESSAGE.  THE CREW RETURNED TO KSDF AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND A BLOWN DUCT ON PACK 2 AND DEFERRED THE PACK 2 SYSTEM.  OVERNIGHT MAINTENANCE REPLACED THE DUCT TO THE HEAT EXCHANGER.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER OCCURRENCES NOTED.
