I installed the roll bar for good tonight.
Remember to install the AN509-10R10 screws that are hidden behind this skin before installing the roll bar. I only installed the lower AN509-8R8 screw completely since I need to be able to flex this skin back to install the rear window.
There are a bunch of fasteners to install inside the roll bar. It’s a pain to reach in here, but I managed to get everything in place without too much trouble.
I also shot and bucked the rivets that attach the roll bar support channel to the aft fuselage. There are 8 AN426AD4-7 rivets tying the top skin, baggage aft wall bulkhead and roll bar support channel together as well as a few more AN470AD4-4 rivets tying the channel to the bulkhead.
Finally, I installed the canopy support channel cover for good. I need to paint a few of these AN509-8R8 (or shorter) screws and replace these at some point, but that can wait for now.
