It's a bit unclear. For the majority of the rivets in the center of the Flap Brace the rivets are AN 470 4-4. They look about right. But then then there is this note on page 14A of the instructions that says, "Rivets may not NECCESS. go through wing ribs." Huh? So, use them even if they're a bit short? Seems a 4-5 would solve that, but it's not called out that way, so I'm confused.
Then the three most inboard rivets require a dimple on the brace and countersink on the aft spar. OK, I guess there are clearance issues requiring a flush rivet. But, I don't see any rivet call out for the outermost two rivets, which must go through the reinforcement plate, and one seems like it NECESSARILY must go through a wing rib?
