## Discrepancy

PILOT REPORTED SMOKE IN THE CABIN WHEN THE IGNITION SWITCH WAS PLACED IN THE START POSITION AND ENGINE WOULD NOT START.  UPON INSPECTION THE IGNITION SWITCH WAS FOUND TO BE BURNED AND MELTED.  THE CONTACTS ALSO SHOWED ARCING AND WAS ALSO BURNED.  IT IS UNKNOWN WHAT CAUSED THIS MALFUNCTION.  THE REST OF THE STARTER SYS WAS INSPECTED AND NO OTHER DEFECTS WERE NOTED.  (K)
