## Discrepancy

(CAN) PILOT TURNED ON MASTER SWITCH AT BEGINNING OF DAY AND GROUND HANDLERS NOTICED SMOKE COMING FROM THE RT ENGINE INTAKE LIP HEATER. THE MASTER WAS SHUT OFF BUT EXTENSIVE DAMAGE HAD ALREADY OCCUREDTO THE INTAKE LIP HEATER. IT WAS FOUND THAT THE ABOVE REMOTE CONTROL CIRCUIT BREAKER HAD PERMANENTLY CLOSED CONTACTS WHICH IN TURN CAUSED THE INTAKE LIP HEAT TO REMAIN ON. INTAKE LIP HEATER AND CIRCUIT BREAKER WERE REPLACED AND AIRCRAFT RETURNED TO SERVICE
