Installed the right wing main tank to check clearance for stiffeners already bent. There's a little more clearance on this side than the other so no adjustment or remake is necessary. Match drilled the stiffeners to covers. First working from the back of panel lined up stiffeners and drilled and clecoed ends. Once the ends were match drilled I removed the stiffeners and drilled remaining holes in panel. Then clecoed stiffeners back on and matched drilled stiffeners working from the holes already drilled from the front side of panels. Put panels on wing to check for clearance and fit. Removed and deburred and dimpled holes.
