The only two biggies that I could find had to do with the crank being
worked on by a particular shop and if the oil pump had a specific part
number impeller in it.

Thanks for the reply! I think I had heard of the oil pump AD. Does it only
apply to certain specific engines or is it an "across the board" AD? Do you
have any idea how expensive a job it is?

I don't think so. It was an airplane I was considering buying, and the
appraiser had no financial interest in the sale.

My mechanic, who can read an AD including preamble and foot notes and
understand it, says he made more than a few bucks from customers who came in
an insisted that he 'do' the AD on the 320 oil pumps even after he advised
them that it did not apply to their engine... Says he told them once, then
if they still insisted that he make some easy money, he shrugged, and did
it...
