Pulled rivet to replace smoking rivets

[jull_under]

Hello.
I have a few smoking rivets on top of the wing. These are the AN426AD3-3.5 rivets that attach the wing skin as shown in the red circle. They run horizontally...wing span wise.

What would be an appropriate pulled rivet to use as a replacement.

Thanks.

Your options are pretty limited for a -3 structural pull rivet.

The go to that vans will usually suggest is a MK-319-BS, but you'll have to enlarge the hole to 7/64" for it.

May be able to reach them

Based on your picture, they look to be the ones common to the aileron Bellcrank. With some maneuvering, you may be able to buck solid rivets through the access hole.

Maybe not entirely relevant, but when my RV-4 had smoking rivets on the firewall, they were replaced with #4 screws, as I recall. Much stronger....
