## Discrepancy

AFTER THE MAIN ENGINES WERE STARTED, THE 'RSS SYSTEM FAIL' MESSAGE WAS DISPLAYED.  AN ALTERNATE AIRCRAFT WAS UTILIZED FOR THAT TRIP.  THE RUDDER STANDBY SYSTEM PUMP/MOTOR WAS NOTICED TO BE SLOW AND NOISY.  SMOKE WAS ALSO COMING FROM THE MOTOR.  THE RSS PUMP/MOTOR WAS REPLACED WITH A SERVICEABLE UNIT.  OPERATION OF THE SYSTEM WAS NORMAL.  (M)
