I got careless with my C-frame and made a figure 8 in one of the fuel tank skin holes where a rib attaches. I carefully drilled it up to #30, deburred as much as I dared, then re-dimpled #30. I noticed cracking in that hole and deburred more as much as I dared. This is the result. Still some cracking, it seems.

Most importantly, I already have a support ticket into the mothership for repair suggestions. I am doubtful I have enough edge distance in the rib flange for an AD5 rivet.
What have others done to repair this kind of thing, or is it irreparable? A tank skin is kind of expensive, but I image the shipping could be even more expensive for a component this size.
What say you, oh wise random people on the internet?
