On page 10-16, it says to dimple all of the holes in the 1047 stiffeners. On the same page, it also says to NOT dimple any holes in the skins common to the F-1006 bulkhead and none of the flanges of the F-1006 bulkhead. My question is should the hole in the 1047 stiffener that is common to the 1006 bulkhead be dimpled??
