- For the left side, I slipped the HS-00006 and HS-00005 ribs into place and marked the approximate hole locations on the top and bottom rib flanges with a pen using the holes in the skin as a guide. Fluted as necessary - which they didn't need any fluting
- Match Drilled to #30 and cleco the aft flange of HS-00005 rib to HS-603PP spar, using the holes in the spar as a drill guide. Removed the HS-00005 and match Drilled to #40 the holes in the aft flange of the HS-00006 rib to HS-702 and HS-00003.
- Marked and drilled #40 the two holes common to the HS-00003, HS-702, HS-810-1 or HS-814-1 on the forward side of the spar bars, keeping the holes in line with the holes in the aft flange of the HS-00006. See SEC D-D.
- Reinstalled HS-00005. Aligned the centerline line drawn on the forward flange to the previously drilled holes in the spar assembly and HS-00006 rib. Clamped the rib in place, clecoed the aft flange of the HS-00005 rib to the aft spar and match-drilled the holes in the forward flange of the HS-00005 rib.
- Clecoed the ribs and spar assembly together and match drilled the holes in the HS-801PP skins to the HS-00005 rib.
- Drilled to final size all the remaining holes attaching the HS-801PP skin and drilled the remaining holes in HS-814-1, HS-8101 and HS-00003.
- I Repeated all of the above steps for the right side.
