## Discrepancy

RIGHT ENGINE FAILED TO CRANK UPON APPLICATION OF STARTER.  PILOT NOTED SMOKE AND BURNING SMELL FROM UNDER INSTRUMENT PANEL.  UPON INSPECTION IT WAS FOUND THAT THE IGNITION SWITCH CUPS WERE SEVERLY WORN, AND CONTACT POINTS WERE BURNT. SWITCH WAS REPLACED AND AIRCRAFT WAS RETURNED TO SERVICE.  WE SUGGEST DISSASEMBLY AND INSPECTION OF THESE SWITCHES FOR WORN COMPONENTS AND PROPER LUBRICATION ON A 500HR BASIS TO PREVENT THIS FROM OCCURING AGAIN.
