Brief Description: Drilled cockpit rails and landing gear box webs
Clamped the cockpit rails to the fuselage and match drilled the upper longerons. We used two clamps at the center section bulkheads to pull the edge of the cockpit rails flush with the outer surface of the side skins.
Aligned the outboard edge of each landing gear box web flush with the vertex of its associated longeron by using a cargo strap and drilled the holes.
