Marked and fluted the left HS-404, 405. Aligned, drilled and cleco'ed HS-404. Worried a bit abot the edge clearance of the little tab on HS-404 near HS-702, and the positon of the holes match drilled with the skin onto the HS702 spar. Aligned and drilled the HS-404, 405, 702, 710 and 714 holes. I needed to move the HS-714 hole closer to the edge of HS-702 spar since the open-loop positoned hole was way off and close to the edge of the bracked. Lots of room, tho, on the flange and I lined up the hole with others on the HS-714 bracked. Drilled #40 pilots with a 12" drill and then full size to #30. Fit and edge distance was good.
