    The case does not require spitting for an inspection post prop strike. The procedures are in the manual and the crank inspection requires special rotax tools that include a protractor for the crank and then you then take each cylinder to TDC and measure the twist between all four. This is carried out due to rotax having pressed together cranks. I can attach the manual pages if you like. Also case fretting is a simple pull tq measurement both cold and hot. Both these inspections don’t take long.

    Please keep in mind this if for an engine with an overload clutch and all my inspections where carried out with an approved rotax service Center. This in not all the pages required

    Thank you all for the replies! I ended up purchasing the aircraft and am currently working through plenty of small items. Rubber replacement, adding a return line, some much needed panel an electrical work etc. Based on some of the hoses I removed, I don't think the rubber replacement has been done any time recently. I can't speak for the inside of the crankcase yet until it runs, but I was very pleased with the appearance of the cylinders in a bore scope inspection, as well as under the valve covers. Should have more details on this project in the next few months.
