Anyone care to provide some input as to the installation of the F-915 outboard seat ribs? Manual says they get match drilled later on but I haven't been able to find when. At what point are they riveted in. Also, what has been the process for fluting the curve in them to match the curve of the holes in the bottom skin?
Regarding the F-904 bulkheads: On the bottom flanges of the fore and aft bulkheads that attach to the bottoms skins, there are four holes that are machine countersunk through the center section skin (F-976) and into the flanges that also attach the forward section floor stiffeners. Am I correct in assuming that the rest of the bottom flange holes on the bulkheads will be machine countersunk in the normal fashion and the skins dimpled? Still scratchin' my head!
