What was found
AIRCRAFT CAME TO OUR SHOP WITH SMOKE AND OIL COMING OUT OF TAIL PIPE. 4 HOURS PRIOR, THE AIRCRAFT ANNUAL INSP WAS COMPLETED AND AT THAT TIME THE STARTER ADAPTOR WAS REPLACED WITH THE WRONG PART. THIS AC HAD BEEN MODIFIED BY STC WITH TORNADO ALLEY TURBO CHARGER SYS. THE STC REQUIRED THAT STARTER ADAPTER ASSEMBLY BE CHANGED TO PN 642087A63 THAT INCLUDES A OIL SCAVENGE PUMP. PN A2087A64 DOES NOT HAVE A SCAVENGE PUMP INSTALLED. THE REPLACEMENT PART WAS ORDERED BY ENGINE SN NOT BY STC MODIFIED PARTS LIST. IT WOULD BE RECOMMENDED THAT WHEN ORDERING PARTS FOR STC MODIFIED AIRCRAFT THAT THE STCC HOLDER BE CONTACTED FOR PARTS.
