9,000 hrs and I'm not at all worried about it. I know a guy that owns a
172 with over 17,000 hrs on it and it's still going strong.

That's still less than two years in the air. Unless that time was spent
entirely doing touch & goes (which, I suppose, is possible in a 172?),
shouldn't be any problem.

Good maintenance is the key.
