Sal...you'll never know.
I safety wire every damn thing I can...including my gas cap.
Don't know about aircraft
per se, but growing up in farming makes things like this rather mundane. See, we used big ol rotary aircraft motors atop 60-75' stands on turntables for wind machines to fight frost in tomatos and citrus way back when. You sure don't like having to hang upside down while the suckers are going back and forth on the turntables checking bolts, so you learn at an early age to safety wire everything...just using some plain old plier(s) and a good ol rule of thumb. Same thing on big irrigation pump motors and tractors and whatever they pull (from French plows to harrows)...lots of vibration. Don't have to go to some ol technical school or become a rocket scientist to know safety wiring works...figured it all out before the internet came along. Farmers just know sh!t....guess that's why they make damn good racers.
Twist it like tying a good fishing line connection before ya pull it taught...too tight and you'll weaken it. Keep the untwisted loops for the spokes and the spinner hole short. The line should be snug but not tight. The tension will keep the bolt/spinner/whatever from spinning off. It does not take the place of checking it before running out on the track...whether it's your spinners or your
oil pan bolt.
If ya wanna count the loops the first few times before ya get comfortable with eyeballing it, and it'll help ya sleep nights...cool.
