## Discrepancy

FLIGHT 7584, ENROUTE RAP-FSD AIR TURNBACK/DISCREPANCY: AFTER TAKEOFF, WHILE IN ICING CONDITIONS, THE RUDDER AND LEFT ELEVATOR HORN HEAT FAULTED. THE CREW FOLLOWED THE QRH AND RETURNED THE AIRCRAFT TO RAP. NO EMERGENCY WAS DECLARED. LANDED WITHOUT FURTHER INCIDENT. CORRECTIVE ACTION: MAINTENANCE REPLACED THE LH ELEVATOR HORN. OPS CHECKS GOOD.
