To those that bought supplemental plans and to those building the wing ribs, a sharp eyed buyer/builder (Sean T) discovered that I left out a small vertical rib of the wing rib shown on page 48. I found that this rib was not shown on other views, but still was my mistake for not catching it.
So I added to the down load files- under graphic aids by Scottiniowa a pdf file showing this rev B When approved, it will be available to all.
Sorry for the mild interruption and carry on.
