How would you safety wire this?

Obviously I don't want this to back itself out. How would you safety wire this?

Isn't that a NPT threaded socket for the fuel sumps?

All you need to do is snug up pipe thread. That will never fibrate loose during your lifetime. Quick drains into the tank are never secured other than tightened to the point the fitting doesn't leak'

If necessary, you could drill a small hole in the collar angled up and to the right (or left) in your photo for the safety wire. Just don't drill into the tank.

It took me a while to get comfortable with flare fitting B Nuts and pipe thread fittings not getting safety wire, but they don't. Just make sure they're torqued correctly and then, if you like, put a dot of torque seal in the appropriate spot to have a quick visual confirmation that they've been torqued and they aren't rotating. The only exception I know of is for the flare fitting B nuts in the fuel tanks getting a safety device as per Vans Service Bulletin. I think it was the result of someone simply forgetting to torque it properly...

I guess there is a valid reason for what I think I'm seeing...but it look like there is a threadad plug in place of the expected fuel tank sump drain fitting.

Is this what I am seeing? Do you not intend to sump the tanks prior to each flight?

Safetying NPT plugs is one of those things in aviation I never understood the point of doing. Because if the plug is loose enough to rotate before it ever does its going to be leaking all over the place. I would tighten it and forget about safety wiring.

I am with you and wondering why plugging this port unless he is intending of not putting fuel in this tank, ever?

Pipe threads........permatex#2 and tighten = all good
