Today I fluted the bottom flange on both F-715 end seat ribs. These ribs need to curve slightly to match up with the bottom skin and I used the pre-punched holes as a guide when fluting the ribs. I also pulled out the F-704H side doublers and clecoed them in position. They will help hold the forward and aft 704 bulkhead halves together before I tighten the temporary bolts.
