## Discrepancy

CREW REPORTED THAT DURING FLIGHT RECEIVED AN ENGINE 2 ANTI-ICE VALVE FAIL MESSAGE AND A WING ANTI-ICE FAIL MESSAGE ON THE EICAS.  THE CREW DIVERTED TO KSDF AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED BOTH THE ENGINE 2 ANTI-ICE VALVE AND THE RIGHT WING ANTI-ICE VALVE.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
