I finished tweaking the seat ribs today so that all of the holes in the forward seat pans lined up without having to pry the ribs into place.
I fit the right side outer seat rib and match drilled it to F-704.
I clecoed the aft end of the rib in place through the #30 holes (copper colored clecos) and drilled a single hole through the bottom skin (through the center line I previously marked) to define the lateral position of the rib and then match drilled the #12 hole through the bottom rear of the rib (gold colored cleco on the left). The gold colored cleco sticking out of the side of the rib on the right was just used as a handle to tweak the lateral position of the rib. I need to flute the center portion of the top of the rib to match the curve in the seat pan, so this still needs to come out again before I’m ready to match drill it to the seat pan.
