Over the past two days, I finished section 12 of the instructions. I started off by assembling the Flap Brackets on the 3rd and 8th ribs as well as the torque tube bracket on the 1st most inboard rib. I then clecoed all of the ribs back onto the spar and torqued the AN3 bolts to the prescribed 28 inch-lbs. Finally, I riveted the ribs to the spar.
