Nordlock vs Safety Wire

[erich weaver]

Safety wiring my Whirlwind 200RV prop is a pain and I dread it. Is there any reason why Nordlock washers couldn’t be substituted? The promotional YouTube videos indicate they perform as good or better than safety wire in vibration tests and would certainly save time and aggravation.

I view them as two different things: The Nordloc washers prevent the bolt from making minor movement that will allow it to loose it's elongation. The safety wire keeps it from turning if it were to come loose. Safety wire is not going to do much to prevent very minor movement, so the integrety of the fastener relies on the bolt elongation. The safety wire is more there as a "Safety" Back-up.
I would think the best practice is to use a nordloc washer and then safety wire it.

What is it that you are finding difficult with the safety wire? If you watch a few You Tube videos you will pick up some tricks that make it quite simple and fun.

My vote is proper safety wire can not be beat. Wire is not a secondary catch when properly done.

Vans' answer to this question, at least for the RV-12, is in a post currently a few lines down titled "safety wire".

0.041 safety wire on my prop bolts. Positive thinking may help, think: "maintenance is fun".

Sensenich specifies/supplies Nord-lock washers for their propeller installation on my carbon fiber GA prop, including certified versions of these props.

Ha! Guess you don’t have a Whirlwind 200RV prop!

To clear this up a bit, I believe the response above is referring to post #2 in the following thread:
https://vansairforce.net/community/s...ht=Safety+wire
where Scott from Vans indicates that Nordlocks are in fact used for retaining the -12 prop and safety wire is omitted

Their GA200L FP prop/spinner kit use nordlock. I also used them on brake calipers as well.

We have been seeing the use of nordlocks on props, brake calipers, etc for quite a while now, and have been using them ourselves on brake calipers regularly. Saves time and seems to be very secure.
