Today I got a lot done: assembly of the two flaps, fabrication of the jig for the riveting, riveting of the skins and ribs. Normally I should have finished everything by riveting the skin to the spar, but I run into some problems with the upper skin: the shopheads weren't nicely formed. I decided to drill out all the bad rivets and to do the work on another session. So both flaps only await the spar to be riveted.



The flap hinge is clecoed on the spar. I decided to have the hinge pin inserted by the middle of the hinge. For this I removed one eye of the hinge and added a nutplate on the spar to allow for a hinge pin blocking system.
