Mainly focused on the left-wing. Bellcranks for aileron and flap were attached, including safety wire and lock tight. We ended up drilling holes in the rib flanges for the safety wires, after reviewing what others had done on the Rans S21 builder Facebook page. The plans were silent on where to attach the safety wire. The aileron cable and the flap cable were also attached. The electrical wire holes were drilled and grommeted on ribs 3-10 and the serrated grommets were attached on ribs 1 and 2 on both the left and right wing. After reviewing the Rans pitot tube attachment suggestion, it was decided to fabricated and riviet a plate through which the pitot and the AOA tube will be passed through grommets on the affected ribs. I asked Rans about how close the aileron cables are to rubbing on the strut attachment mount and whether this should be a condition inspection item. Here is the reply "Yes, add that to the list, we inspect that every annual, so far no issues, we do place anti-chafe tape in the area of possible contact."
