Prepared the ailerons and their attach fittings by drilling the holes out to #12 size, deburring, and priming where needed, then bolted the attach fittings to the ailerons.

I attempted to attach the aileron pushrods to the bellcrank, but I'm missing an AN3-21A bolt. I have no idea why it's not in its drawer, but nobody at the airport, not even the maintenance shop, had a replacement one in stock. They had -20As and -22As, but no -21As. I'll order one tonight.
