I'm studying to do the same thing, and I read about an AD that might
affect you. Apparently, if the plane has any sort of strike, there's
some sort of requirement that the wings be pulled and inspected in some
certain special way. I don't have the specific bulletin in front of
me, but the book I was reading said that Cherokee buyers need to look
for a plane with a clear history, complete log books, or have evidence
that the proper wing strength inspection was performed. Crud, I'm sure
I'm pooching up the description, and I don't have my book with me. If
anyone else knows what I'm talking about, please feel free to jump in.
