Aileron Rib to Spar -4 Rivets

[Steve W]

-4 or 1/8" countersunk rivets are shown on the top of the aileron where the rib is attached to the spar. The plans show 8 of these. What about the bottom of the aileron? Anyone know the answer to this? Thanks to those who respond.

The plans do only show them on the top. I was only planning on installing them on the top. Of course upsizing the rivets on the bottom would not hurt if you wanted. I figured they were only on the top to deal with the twisting force caused by the aileron push rod on the top of the hinge attach on only the inboard side.

Thanks John.
I have a misaligned 3/32 rivet on the bottom which will clean up with a 1\8".

I plan on putting them top and bottom.
