## Discrepancy

ON CLIMBOUT, PILOT WAS UNABLE TO CONTROL CABIN ALTITUDE.  AFTER LEVELING OFF AT 10,000, CABIN CONTINUED TO CLIMB.  RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  FOUND PRESSURIZATION CONTROL PANEL DEFECTIVE.  REPLACED PANEL IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-31-01, OPERATIONAL CHECK GOOD.
