Brief Description: 1.- Drilled the wing attachments upright o/b holes
I decided to detach the firewall so I could work on the wing attachment uprights and the installation of the forward torque tube bearing. Drilled the upright channels. This took me a long time. I had to work on the side skins spar openings since they were touching the spar. The upper section of the opening is not flush with the side skin. Once that was out of the way, I was able to drill the uprights.
