I spent this session doing some of the rib repairs necessary on both wings. There are several rib patches in place already, but they were not done well, so I either made the existing repair fit better and riveted them into place or just replaced the repair material altogether. To do it neatly and with good structural strength takes a while and id fairly tedious, but the results certainly look better.
Good example of the corrosion on the bottom of the rib.
