Brief Description: Left Rib #9 Bellcrank subassembly
Tonight drilled the pilot holes for the vertical stiffeners as well as the pilot holes for the bellcrank subassembly. Deburred the rib itself and the stiffeners, but still have to up-drill to #30 for riveting.
Remaining work prior to riveting is the fitting of the stiffener-to-skin attachment clips.
