Riveting skin to first center rib

[Jsabol]

In the process of finally driving the rivets on my wings. I'm at the point where they are drilled, deburred, and dimpled. Regarding the first center rib (the one that is doubled), do you rivet both flanges or only the inboard side?

I am not to this point yet, but I would have to say that both rivet flanges would need to be riveted since the wing root (I believe) would see the greatest stresses in flight. Those who are past this point, feel free to correct me if I am wrong.

I riveted both on mine.
