W21-01R Wing Rib #9 Assembly - Today I drilled the pilot holes in the -09 Angles. I also drilled the pilot holes in the -13 and -14 Fwd and Aft Vertical Channels for the right hand rib #9 assembly. I then clamped -14 Aft Channel to the rib and drilled the #40 holes. After that I did the same for -13 Fwd Channel. I clamped -02R Right Hand Bellcrank Pivot Assembly to the rib and drilled the #40 holes. I located and drilled the #40 holes for one of the -09 Angles.
