I match drilled the bottom skins.
The leading edge rib was fixtured to the leading edge skin and match drilled to the spar.
The fuel tank connecting strip was located between the leading edge skin and the ribs.
It took a lot of work to get the rib and strip to line up properly. I installed cleccos in all the holes that were match drilled.
I drilled the hole through the skin for the tie down eyebolt. The hole may be slightly off centered from the bracket.
I deburred and fluted the right leading edge ribs.
The ribs were clecoed to the leading edge skin.
The leading edge was clecoed to the spar.
