Finishing an RV6, doing the wings last. Have the nice Phlogiston spar. Dwg 20 shows a AN3-12 bolt attaching the tiedown to the spar, going through the top flange strips. That hole does not exist in my spars and I will have to drill it. I've drilled through the spar web to attach the ribs and have drilled through the spar flanges for the skins, but all of the other holes that were required, for the AN3 bolts that attach the ribs, were already in the spar. I'm just looking for some reassurance before I drill through those flange stips. It's only through the flange strips at the top of the wing (probably typically in compression). The tiedown attaches differently at the bottom of the wing, not through the flange strips but through the web and to the reinforcement angle. Anybody remember how they did it on their 6? Thanks.
