Drilled and countersunk all the holes at the wing root. A couple of the counter sinks are too close to the spar flange to use the cage so I did them by hand with the deburr tool. Not a problem. Got stuck when I realized I don't have any AN426AD4-6 rivets that are called for. Doubled checked the inventory and they're not there. Just trimmed some 4-7s and squeezed them no problem.
Match drilled and countersunk the holes in the tie down. Installed the -3 nut plates. Actually installed an extra set of nut plates for AN bolts that weren't needed. Drilled them out and I'll just have a few empty rivet holes. Edge distances are good so not a problem.
Cleaned up the aileron bellcrank brackets, bolted and final torqued.
Right spar is complete.
6/26/22 update: finally looked at the autopilot install instructions and I now see that Garmin's bracket actually replaces the lower aileron bellcrank bracket. Removed the bottom bracket and replaced with Garmin's. I'll final torque after the servo is installed.
