You are right. Anytime a part moves in a part castle nuts with cotter keys are used.

I always thought, and have since confirmed in AC 43.13 par7-64a, "DO NOT use self-locking nuts on parts subject to rotation." I saw many aircraft both experimental and certified that used locking nuts in situations that I thought would have called for a castellated nuts and cotter pins. http://www.kr-2s.com/images/krnet/tecnam1_800.jpg I would like to know if I am misinterpreting the rule, that maybe it is ok to use self-locking nuts here and that if the bolt was reversed, and the nut did up on the rod end bearing side of the flap actuaror, that a castellated nut would be used instead. I am not trying to be a "Smarty Pants", just a little confused as I saw this on many aircraft.
