F25-01R Right Hand Aft Side Panel.
Today I located the vertical Zee #1 using the blue bend line on the aft side skin, The Zee was also located down 1 and 1/8th inch from the top of the upper longeron. I then drilled the #40 pilot holes in the Zee using the pilot holes in the aft side skin as a guide for location.
I also up drilled to #30 those holes that will be riveted on this assembly. There is 4 holes that were up drilled that will not be riveted at this time. I placed some blue tape on those clecos to remind me not to rivet those holes.
