Today I started off by un-clecoing the left wing tank skin from the outer ribs and baffle to get access to the baffle/z-brackets. Then with the copper clecos in place on the ends of the baffle, I match drilled the remaining z-brackets. I then re-clecoed the skin back to the ribs and baffle and match drilled the baffle to the skin and ribs. Next session I will perform same steps to the right wing and tank.
