Your right about the pre-purchase and I have an A&P who is also an IA ready to do it for me. I have discussed this with the owner: he is OK with it, but wants to be present. The pre-purchse will be the equivalent to an annual. However, my inspector told me that he would pick up on the lack of 337's (even though the airframe is sound) and he would require the owner to resolve this issue.
