aileron hinge bolt/nut

[fehdxl]

Please correct me if I'm wrong, but the picture below depicts a less than desirable technique of mounting the aileron to the wing....right?

A cotter pinned castle nut with the next size smaller bolt would be ideal, right?



Thank you for your time!

P.S. Sorry for the low picture resolution.

Jim,
.... that is acceptable as long as the bolt is tightened against the inner ball (or race) of a bearing.
That is what is happening in this particular spot - and many other RV locations.
The bolt is not the pivot point, if it was, then the castle nut and cotter pin would be required.

It's OK...
