Worked on rib 12, 11, and 6 by adding stiffeners to ribs as per drawings. 12 and 11 have U-14 added vertically to them and 6 has two angles added to it. Primed rib 12, 11, & 6. Drilled and clecoed ribs 12, 11, & 1 checked spars for straight and level. set gas tank in place to check fit. Looks good.
