W07 Wing Box - Left Wing - I filipped the wing over. I used ratchet straps to pull the leading edge skin into position. I clecoed the skin starting in the middle and worked out to the sides. I then drilled the #40 pilot holes into the forward ribs from the lower side of the leading edge skin. W17 Root Rib Installation - Forward Root Rib Left Hand Wing - I positioned the rib in place behind the attach angle on the main spar. I drilled a few locator pilot holes. I removed the attach angle from the main spar. I started drilling pilot holes through the Attach Angle Forward Rib and the Reinforcement Angles.
