## Discrepancy

AFTER DEPARTURE, THE CREW RECEIVED A AIRFOIL DE-ICE SYSTEM FAIL.  THE CAPTAIN CONTACTED MAINTENANCE CONTROL AND WAS INSTRUCTED TO DIVERT TO CAK.  FLIGHT 4135 DIVERTED TO CAK WHERE MAINTENANCE INSPECTED AND REPLACED THE EJECTOR FLOW CONTROL VALVE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 30-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.  FLIGHT 4135 CONTINUED WITH NO FURTHER INCIDENTS.
