Default N200LZ: Chapter 8 - Click Bond fasteners

I have not worked with Click Bond fasteners but I'm wondering if I could use these for my connect points for the shoulder straps of my harness. I know that they are used in some of our structural areas.

Could they be used here?

Those that JD provides are quite small (#10-32), TMann. Even if you can get the math to say it's Ok (which I'd question for impact loads), they probably wouldn't pass the smell test with any passengers.

The harness attach points I've seen have all been 3/8" or 5/16" through bolts in plastic planes like ours and in tube/fabric acro planes. Beefy. While you can certainly find larger Click Bonds, I'd stick with the "beefy" fasteners plus bonded inserts plus plenty of glass just in case you ever need to use them.

Of course a lot depends on the details of installation, but I would think that if you're using the clik-bond adhesive to carry any sort of loading for crash-load purposes, you're likely to be fatally disappointed in the performance (possibly literally). If you're not using the adhesive pad, why use clickbonds?

Certainly, a surface-applied clickbond would be wholely inadequate for a seatbelt hardpoint, in my opinion.

Crash-hazard loading are pretty extreme, the idea is to have the body restrained up to g-loadings beyond which you'd be dead anyhow, and that, for short duration impacts, can be surprising high.

That all makes sense.
Like I say, I've never used them or seen them. I've read a good write-up on the Cozy Girrrl site.

I figure I'll do the nutplate arrangement like they have on the Aerocanard.
I'm not sure if that's the same as they do on the Cozy or not but it is better than the original Long-EZ plans.

TMann, Can you point me to a pic of the nutplate arrangement on the aerocanard?
