Doesn’t look like an “A” flap to me.

Jim, if you havn’t already sold the “A” how does it compare?

Bruce, I sold the A and now have a B. The pics are from the B. I went into the control panel to change
things from the A to the B, but don't see a way to do it.

I checked the end rib set up on a Cardinal recently and found it
had the same configuration as my 170B. That is, some of the
end ribs were installed with the flange showing.
I’m convinced that Cessna did this so they could just squeeze
those rivets instead of bucking them to simplify the manufacturing
process.

As to which planes got that treatment and which didn’t, who knows?

My '53 170B (which had it's ailerons meticulously rebuilt) and my '62 172C (which has it's original ailerons) …. do not display "flipped" ribs. They are flush at all ends.
