## Discrepancy

CREW REPORTED THAT DURING FLIGHT RECEIVED AN ENGINE 1 ANTI-ICE FAIL MESSAGE ON THE EICAS.  THE ENGINE 1 ANTI-ICE VALVE WAS PREVIOUSLY LOCKED OPEN AND DEFERRED.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND THE FAULT REMAINED.  RETURNED TO KRDU AND LANDED WITHOUT INCIDENT.  MAINTENANCE SECURED THE VALVE CLOSED AND RECLASSIFIED THE MEL FOR ICING RESTRICTIONS.  CMH MAINTENANCE CLEARED THE DEFERRAL LATER THAT DAY BY CHANGING THE ENGINE 1 ANTI-ICE VALVE AND THE ENGINE 1 PRESSURE TRANSDUCER.
