## Discrepancy

CLIMBING THRU 9000 FT THE -CABIN ALT- CAUTION MESSAGE ILLUMINATED.  THE CREW FOLLOWED THE QRH BUT COULD NOT RESTORE PRESSURIZATION.  THE FLIGHT RETURNED TO CLT AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NR 2 CABIN PRESSURE CONTROLLER.  OPERATIONAL CHECKS WERE GOOD.  THE AIRCRAFT WAS RELEASED FOR SERVICE.
