## Discrepancy

(CAN) ON SHUTDOWN OF THE RT ENGINE, THE CREW NOTICED THE RT PROPELLER CONTINUED TO ROTATE. THE CREW TURNED OFF ALL POWER ON THE AIRCRAFT AND THE PROPELLER STOPED ROTATING.  INVESTIGATION SHOWED CONTACTOR 2431-K2(P/N A-A4N103) WAS STUCK IN THE CLOSED POSITION.  CONTACTOR WAS REPLACED AND AIRCRAFT RETURNED TO SERVICE.  (STARTER/GENERATOR ALSO REPLACED AS PRECAUTION)
