+++DONT BE CONFUSED - this issue is NOT about the inboard flaperon "skin" rubbing against a fuselage side rivet!+++
My rivets also touch. Seems to be only enough to take off the paint but I only have 20 hours. Note that because they touch, this limits flaperon travel. This is an interesting problem for several reasons.
(Now, it does look like drilling out/replacing one LP4-4 rivet with a CS4-4 rivet will solve the issue. Requires pulling the wings out a couple of inches and maybe taking off the flaperons to get at it. FYI this is the rivet on page 14-03, bottom-most outboard rivet attaching the W-1212 hinge assembly on either wing. Noted as "leave open" on this page, later riveted on page 15-06 using LP4-4.)
But...
Remember in the PAP how you check for PITCH travel limits. You are supposed to hit the limit on the tail just before you hit the limit on the stick. I've seen mention of checking with a piece of paper as a feeler gauge up at the stick end and did that.
But what about the roll limits?
On page 32-10 you are match-drilling the flaperon torque tubes with the flaperons in their neutral position. Then you take the wings off and finish up the flight controls. You later reattach the wings in Section 33 but there are no instructions about checking flaperon travel there. Nor in any later section of the plans! (And no relevant revisions posted about Section 32.)
When you get to the Production Acceptance Procedures (PAPs) Section G2, you do several full range move-the-stick-around tests. This rivet interference could define your limit of flaperon deflection with flaps up. You would not "feel" it as interference. You measure some distances about the anti servo tab and the rudder. But you never measure anything about the amount the flaperon moves up or down compared to, say the wingtip skin. That is all controlled by carefully making the pushrods to specified lengths on page 32-05 and -06.
So this rivet interference, until fixed, is perhaps defining the flaperon max upward travel. (What DOES/SHOULD define that? My memory and drawings are not making that clear and I don't want to start removing cover plates to see.)
My kit is #412 and I don't see any relevant revisions to Section 32 or 15. My PAPs are Revision 1.
What say you experienced folks?????? I tried but could not find this in a prior thread.
