Brief Description: Identify ribs, mark and drill holes in flange of H
Choose chich ribs will be used on the right and which will be used on the left and then mark them.
Using the dimensions given in section D-D, mark the hole locations on the centerline of the aft side of the aft flange of HS-00006. These holes attach HS-00006 to the forward spar assembly of HS-00005. Make a light mark with a center punch to keep the drill bit from wandering then pilot drill the holes to #40. Note, locating section D-D on the plan took forever. For whatever reason I just couldn't see it. It is located on the mid-left side ofDrawing 3.
Draw a centerline on the forward side of the fowrard flange of HS-00005.
