## Discrepancy

CLE FLIGHT 2651 - THE CREW REPORTED THE CABIN PRESSURIZATION ALT WENT TO 10,400 FT IN CRUISE AT 28,000.  AN EMERGENCY DESCENT WAS PERFORMED AND THE AIRCRAFT LANDED IN CLE WITHOUT FURTHER INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE PRESSURIZATION DIGITAL CONTROLLER.  OPERATIONAL CHECKS WERE GOOD.
