Default Wing rib dimpling

On page 14-02 it says to dimple all lower wing rib flanges. I understand the 4 most inboard ribs will have the skin countersunk over the wing walk doubler, but why don't the remaining ribs get dimpled both top and bottom?
TIA

Kerry

I dimpled the tops and the ribs under the wing walk doubler. Dimpled the doublers and the skin also. Couldn’t bring myself to c/s .032 skin. Turned out fine. Just make sure you use a longer rivet through the doublers. Think I used 4.5 long but not sure.

Exactly correct. Same for the RV-10. Dimple the skin, the doubler and the rib. Did this on three sets of wings and they came out perfect.
