Today, step 5 (17-05), 2 (17-06) and 3 (17-06) were completed. Steps 1 through 5 of page 17-05 (Right Wing were completed as well and step 2 (17-06, Right Wing) was started. On step 2 (both wings) to rivet the some of the most outboard rivets, the ones that match with the tip rib had to be done with a manual riveter. The problem is that the shop head of the rivet inside doesn’t allow the new rivet to set flushed without shortening it a bit. All steps on the right wing were done the same way as the left one.
