Darren,
When using rod end bearings ("Heim"), the ball needs to be "captured" on
both sides with washers, spacers or whatever. Nyloks will work ok in this
application, but I wouldn't use a castle nut and cotter pin. A castle nut
sometimes needs to be moved (loosened) a bit in order to accept a cotter
pin. As Dana points out, you don't want the bolt to rotate within the ball.

Darren, while your conclusion is generally dictated in 43.13, there are
examples where the use of a self locking nut is acceptable. A couple of
examples: picture an aileron bellcrank with a hollow core pivot point, if a
spacer is inserted through that pivot point which allows the nylok to
tighten up against the spacer, even though the bellcrank moves, the
bolt/nylok combination does not. Another example would be an aileron pivot
bracket mounted to a wing. Once again, if a spacer is used between the two
flanges of the bracket, which allows the nylok to tighten down, it is
acceptable. I was careful to use the word generally in my first sentence as
there are places where a piece moves and a nylok is acceptable.
