My mom was in town for my Aunt Colleen’s birthday, so I only got a few hours in the hangar today.
I secured the aileron nose ribs to the counterbalance with a blind rivets. 
I installed the aileron leading edge skin with clecos.
I riveted the nose skin to the nose ribs. I had to drill out one rivet.
I riveted the inboard and outboard reinforcement plates to the aileron spar.
Lastly, I riveted a nutplate to the spar. I had to countersink the doubler plate before installing the flush rivets.
