safety wiring the prop

[miyu1975]

Does any one have a good photo of their safety wired prop. This is on my to do list and I am wanting to make sure I do it correctly. Also, what gauge wire is recommended for this..thanks in advance.

No photo, sorry.

I used .040" on the prop nuts, however the instructions from MT said to use .032"-------

The 0.40" fit just fine, and from some dark corner of my mind, I seem to remember the FAA likes to see the larger size on a prop.

I figured I could argue the manual against FAA norms, but why bother.

Good luck, tis a pain to get the wire started in some of the positions, I ended up backing off the nut, and inserting the wire prior to re-torquing on a few.

The inspector MAY require more than the manual recommends.
For example, there are a couple of prop manufacturers that say you don't need to safety at all.
I still require some kind of safety method, whether it be lock nuts, jam nuts, or safety wire.

What type of prop?

Safety wiring a fixed pitch prop and a constant speed prop are two completely different animals.

My Hartzell manual specs .032 safety wire and that's what I used.

Sensenich recommends 0.040 for their metal props.

Safety wire per the AC 43-13 standards.

Ryan,

I do not have any pics of my Safety Wiring but I can give you one hint that will save you much frustration and time. On the CS prop, you will always have a few of the nuts that you will not be able to thread wire through while the nuts are tourqed. Loosen up the nut first, run the wire through, twist the wire then go back and Torque the nuts. A little challenging to guestimate the length but it's the only way. Also, wire them in pairs.

Hope this helps.

Here is something I googled. It is not an RV. It shows the safety wire preventing the nuts (bolts) from undoing. Hope it helps.
Use 0.040 as Gil suggests.

Also here is a link to Experimenter Magazine with some good advice on safetying:

Look awfully loose to me. The bolts can turn ccw quite a bit before the wire does any good. The run between one bolt or nut and the next should be as tight as you can get it.

REALLY LOOSE!

I'm sorry to say but that lock wire won't pass, it's way too loose and twisted too many times, your tails should be turned back on itself so you don't end up with a nasty puncture wound. That's my opinion, I'm sure others will say different.

Cheers,
