NTSB Narrative Summary Released at Completion of Accident

WHILE DESCENDING THROUGH 7500 FT THE PILOT OBSERVED SMOKE ENTERING THE COCKPIT FROM THE INSTRUMENT PANEL AREA. AN ATTEMPT WAS MADE TO ISOLATE THE SOURCE BY SHUTTING OFF VARIOUS ELECTRICAL COMPONENTS. THE SMOKE CONTINUED TO APPEAR INTERMITTENTLY BEFORE THE AIRCRAFT REACHED ITS INTENDED DESTINATION. LATER INVESTIGATION REVEALED THAT A SLIGHT OIL LEAK ALLOWED OIL TO DROP ONTO A HEATED EXHAUST SHROUD AND PRODUCE SMOKE WHICH WAS INGESTED INTO THE COCKPIT THROUGH A DEFROSTER VENT UNDER CERTAIN CONDITIONS. THE OIL LEAK WAS FROM THE LEFT REAR ROCKER COVER.
