Default Your "many" nut plates.

This may be old news to many but I wish I had been reminded early in my build.

Tapping nut plates.

Default nutplates

Do what you want, but they will no longer be self locking.

Default That is hard to believe

It is hard to believe that the EAA would put out a video telling people to cut out the deformed locking feature of a platenut, anchor nut or it pains me to say it nut plate.

I find a lot of things people suggest to do to aircraft hard to believe. Biting my tongue most of the time.
When working airline overhaul I've spent entire shifts removing/installing one fastener.To bad if it was a pain to do it correctly ie. aircraft standards.

Wow. And he carefully shows how to start the tap at a 15 degree angle to the axis of the threads, too.

Are we sure this isn't an April Fool's video?

Hard to believe, but I do think he was serious.

Default thanks for pointing this out

Holy ****, these types of things must be part of the reason for higher than acceptable accident rates for phase 1 flying. I had already watched this video from EAA and only my lazyness kept me from getting a tap tool and doing the nutplates on the VS-rudder.

When I was installing the bolt-hinge connections, the bolts were difficult going in. I assumed I had received louzy platenuts, so I went to the EAA site and looked up platenuts and watched that video. For once, being lazy actually paid off.

Some things such as tapping a plate nut would never be caught by an inspector or mentor unless they were there when you were doing it. In the case of the VS-Rudder, it isn't really possible for the bolt to come lose because of the configuration, but there are others that could. I am sure there are opinions both ways with this, but it drives the point home to research and use your own common sense and not follow anyone or anything blindly.

I have sent an e-mail to EAA asking that this video be removed.
We'll see!

Bolts are one thing. Access panel phillips - head screws are another, correct?

Default plate nuts

If the engineering didn't want a self locking feature, why didn't they just call out tinnerman nutplates? Yes they are called nutplates. Even access panels can be a load bearing part that you don't want leaving the airplane.
