Hi guys,
I'm looking for confirmation (or not) that I'm doing a repair correctly. I screwed up the landing light cutout on the R outboard leading edge wing skin, thus I spent all day today removing said skin in order to replace it. I have drilled out all of the rivets and removed the skin itself. Not surprisingly, some of the drilled out holes are out of tolerance for being re-riveted.
Question #1: I'm using 50 % out of round as my upper limit of acceptable for re-riveting. Is this reasonable? I can't remember where I learned it, and haven't had much luck finding the original reference (if it exists.)
Question #2: Assuming the above criteria, I have about 20 holes that will need something other than an LP4-3. I have some 5/32" rivets from the local hardware store. Is it acceptable to match drill the new skin with a 5/32" bit and use those rivets?
Thanks for any feedback,
