## Discrepancy

ON APPROACH INTO MKE THE FLIGHT CREW REPORTED A RMU 2 FAILURE WITH RMU, ALSO NOT WORKING PROPERLY.  MKE APPROACH WAS THE ONLY FREQUENCY THAT RMU WOULD TUNE.  THE CREW RECEIVED LANDING CLEARANCE FROM APPROACH AND VERIFIED THE GREEN LIGHT FROM THE TOWER AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NR 1 RMU AND RESET THE NR 2 RMU WITH NO FURTHER DEFECTS NOTED.
