Forgotten mistake - opinions needed
 

I vaguely remember botching a rivet on the aileron a long time ago. While re-installing them after doing the bottom skins, I saw it and now need to fix it. Question is, what's the best way? It is the last rivet on the inboard side closest to the trailing edge on the top skin.



This is with an "oops" rivet just resting in the hole. It doesn't fill it up, as the hole was double dimpled.

Drill out to #30. Dimple then rivet #4. No one will ever notice.

What Carl said.

That looks a bit big to just drill out and upsize. If you can't get a clean hole as Carl is suggesting, put a rivet on each side, observing edge and hole spacing, and fill the hole before you paint.
You won't notice that later either.

Agree. I had the same thought.

Yeah it's already drilled out to a #30 hence the oops river. I think I'll have to go with a river on each side and filling the hole. Good idea on that.

Having a hard time envisioning putting a "rivet on each side" of the damage so that it fixes this.

When your done a followup picture would be nice.

He's going to drill two new holes; one on each side of the bad hole, then install a rivet in each of those holes and fill the bad hole with goop, cure and sand.

Thanks Mike - I guess my post left me open to Mr. Obvious. :p

My concern was more the rivet spacing and cleaning up the existing hole - oversized to eliminate rough edges. Wondering how it all fits in the constraints.

I'll post a post repair picture. Checked with my sheet metal guys at work, and they said to flatten the dimple, drill out larger to clean the hole and put a small "backer" plate behind the rib to cap the hole and provide a surface for micro to cling to. Place a rivet on each side (essentially spacing them closer together) and let it ride.

Thanks for the suggestions!
