## Discrepancy

YYC - FLIGHT 2329 - CREW RETURNED TO FIELD WHEN THE CABIN PRESSURE MASTER WARNING LIGHT ILLUMINATED.  CABIN PRESSURES WAS ABOVE 10,000 FT AND CLIMBING AT 500-700 FEET PER MINUTE.  THE CREW WAS UNABLE TO CONTROL THE PRESSURE MANUALLY.  MAINTENANCE INSPECTED THE AIRCRAFT AND REPLACED THE CABIN PRESSURE CONTROL PANEL, AND THE CABIN PRESSURE CONTROLLER.  OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
