## Discrepancy

MX INSPECTED THE ELECTRICAL SYSTEM FOR SHORTS OR BURNED WIRING, BUT NO DEFECTS WERE NOTED.  THE SMOKE WAS DETERMINED COMING INTO THE COCKPIT, DUE TO OIL SPILLED ON THE MUFFLER HEAT SHROUD AND ENTERING VIA THE RAM AIR INLET.  THE OIL WAS CLEANED FROM THE HEAT SHROUD AND A RUNUP WAS PERFORMED WITH NO SMOKE NOTED.  THE AIRCRAFT WAS THEN RELEASED FOR FLIGHT.  (M)
