We're mocking up the two top skins F-1074 and 1075 in the tailcone to drill the stiffeners. On Page 10-12 Step 3 it indicates that the flanges with two holes should be "Heavily Fluted" prior to clecoing the skins. Why? We put the skins on and they clecoed up just fine to the bulkhead and frames. Am I missing something?
