Brief Description: Remove Wing 5: Platenuts on wing rib
The wing inboard ribs need the holes for the skin and fairing debured, dimpled and platenuts added
I dimpled holes on the bottom, nose and fairing. But the holes on the top of the wing had to be countersunk because the top skins are riveted on and include 3 pieces of sheet: 1) skin, 2) doubler, 3) rib flange. I countersunk both the #8 hole and the #40 rivet holes.
