Fitted the Center section to forward section and mid section. Installed nutplates and rivets to mid cabin braces per plans Installed AN4 bolts to Mid cabin braces to Center Section and riveted midcabin braces to Center Section. While installing the AN4-12A bolts in Mid Cabin braces, I noticed more thread showing than in the 12 AN4-11A bolts I had installed per plans in the initial Center Section assembly. I had heard of a builder who had issues from an examiner during final inspection about not having threads showing through nuts. Sent an email photo to Van's for advice. Riveted F814 seat ramps to F814 CR &L seat ribs Clecoed F815A and F815B outboard ribs to F806B spar. Installed AN310A bolts and torqued bolts to 25 inch pounds. Riveted F815B rib to F806 spar to F815A rib Riveted F815A R&L to F826 and F827 bottom skins
