Wing patches
Is there a limit in how many patches are allowed on a Cessna wing?
Re: Wing patches
Well... I've seen some wings....
I think that pride in workmanship would kick in before a "number of patches" would become a factor.
If the pride in workmanship doesn't kick in (which I have seen a few times), think of it this way: Would the addition of patches approach the skin discontinuity which would equate to a layer of frost? I saw a horribly repaired 172 wing once, and was questioned by a third party. "Would you fly it with that much frost on one wing?" I asked. A no hesitation "No". Well then, the criteria for the repair is in doubt.
I don't see a number with respect to wing skins in the Cessna manuals, nor AC43.13, but there are clear guidelines for other flying surfaces...

Re: Wing patches
8 on one and 5 on the other wing. Wing patches usually have other damage underneath. Was just wondering if there was any max numbers. I realize this to many patches.
Re: Wing patches
You may also want to consider where the patches are.
Are they near the spar? Across ribs? Under the fuel tanks?
Every picture tells a story. You may want to find out what is causing them to crack in the first place. High time? High vibration? Was it parked in a hail storm?
