On the RV9 fuselage does the forward F972 bottom skin that rivets to the center spar section carrythru get dimpled or countersunk? The F972 skin is 0.040" and I think the flange on the center spar section is that thickness also. I haven't found where it is called out either way. My thought is it is better to countersink the skin then the center spar section flange. I see there are 4 rivet holes called out that are to be countersunk on the seat/baggage area bottom skin so these 4 places must be dimpled on the corresponding F972 skin.
Just wanting to make sure I am not missing anything here.
