SECTION 26: MID FUSE RIBS & BOTTOM SKINS
PAGE 26-5
Consider at this point whether you need access holes in the F-1017 under-seat ribs for conduit and/or antenna wiring. Many builders cut holes in the F-1017 ribs for conduit passthroughs. These holes will be much easier to cut at this point.
Also consider marking and cutting/installing antenna doublers on the bottom skins in this general section. This will be much easier now than later, when the seat plates are permanently riveted in place.
