Mine only has about 3500 hours on it, mostly relatively gentle hours since I've had it and none were ever as a trainer, and really it's not all that different from a 172 in construction, so it's curious that it's not listed.

Could be it's not listed because the landing gear on a 'D' or 'E' model is built from battleship steel springs

I know my "E" model hasn't landed on a gravel bar in at least 3000 hours, and likely not before either. Nor has it missed an annual inspection. I'd bet most of us have heard of some operator who diligently did an annual every four to six years 'whether its needed or not' :O. An added buffer for the early model 172's are much smaller useful load and a lower landing speed than a 200 series or even 18X series airframe. Being a bit underpowered probably helps keep the loads down

. All would argue a wholesale AD or other inspection regime would be out of line (for that issue, anyhow).
