Wink Oops, is this considered a lightening hole?

As I was dimpling the bottom rib of the rudder, I wondered how some builders could POSSIBLY make the figure 8 mistake. I thought it could never happen to me.... well, it didn't, but I came very close. I made a lightening hole!!




I flattened the dimple with the rivet gun and it looks pretty good. I am inclined to press on but wanted to run it by the masses. The original hole remains intact and not affected. Even the edge distance is borderline acceptable.

Let me guess; you where using a pnuematic dimpler?

As long as you have the edge distance between holes and the edge, you have nothing to worry about. Debur the hole and move on.

I figure I had an even half dozen such non structural devits over the many years and two planes. JB Weld is the answer. Move on & good luck, Bill

I have a rule that an "extra" hole that is left alone is a lightening hole. If
I can put a rivet in it, it becomes a BAR, "Builder Added Reinforcement"

It's probably OK as is, but if it were mine, I would put on .032 or .040 backing/doubler strip on the inside rib flange capturing at least both the rivets on the either side of the offending hole and rivet it all together with the skin. I'm not a big fan of using JB Weld on an airplane, except perhaps in very rare circumstances on non-structural items, but that's just my opinion.
