Brief Description: Drill top F-786A J Stiffeners through aft top skin
I only partially clecoed on the aft top skin. I left open the bottom so I could reach under and hold the F-786 J Stiffener in place while drilling it through the top skin. Worked good for me.
Notice in image 3 the aft end of the top J stiffener that does not require the complex end trim like all the other J stiffeners.
