## Discrepancy

(CAN) THE FLIGHT CREW REPORTED THAT THE RT PROPELLER HEAT B PHASE WAS STUCK IN THE ON POSITION. THIS WAS CONFIRMED WITH THE LOADMETER. THEY PULLED THE CB TO DEACTIVATE THE SYSTEM. MAINTENANCE INVESTIGATION RESULTED IN REPLACEMENT OF PROP HEAT RELAY 3061-K4 WHICH HAD COANTACTS A1 AND A2 STUCK CLOSED. THE RELAY WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
