Riveted left flaperon skeleton. Checked fit of aft skins - they were good so no need to adjust bend of trailing edge. When you cleco the outboard nose skin over the counterweight, start by clecoing the counterweight holes. I started with the top edge and got a nasty fright as it appeared the holes in the skin did not line up with the holes in the counterweight. they do - if you start witht he counterweight holes!
Riveted all the skins so the left flaperon is complete. Now to do it all over again on the right flaperon.
