Electronic drawings show a fiber insert nut, no?

Did this last night. Looking at the electronic drawing file:
Drawing 20, area F-1 shows:
AN3-10A bolt
AN960-10 Washer
AN365-1032

Is not an AN365-1032 have a fiber insert?

That is just part of the F-705 bulkhead assembly. The discussion is regarding the actual wing rear spar attachment. See Drawing 38, Section H-H, Zone A4.

Hey Ben,
Check out #38 section H-H. The bolt that he's referring to is the one that connects the rear spar of the wing to the fuselage.

At least on the vintage for my 6, the bag contents for this hardware was an AN365 and A bolt. That is what the factory provided. They didn't provide a drilled bolt. This might explain why so many are this way.
What is in the current kits inventory sheet for this bolt? Do they supply the correct bolt and nut?

I check mine at each CI, and while it makes sense that this bolt can move, mine has always remained torqued. So, each time I get there in my CI, with full intent of changing it out, I check it and move on.
I am not arguing this shouldn't be a drilled and safety'd assembly, but, the factory didn't seem to care at the time.

I think this falls into the category of "good practice", rather than a true safety concern. I have never heard of any issues related to using a nyloc here, but I am not saying it isn't a good idea, and it is what the plans show.

And we're not just talking about the -7/7A, right? So, on the -9/9A, on drawing 38 Section G-G, it lists:

AN5-10 Bolt
3x AN960-516 Washer
AN310-5 Nut
MS24665-208 Cotter Pin

These attach the W-907 Rear spar assembly to the F-705 bulkhead assembly.

Cheers,

Yes, but what does Van's supply you with? I am curious.

I am the second owner of my kit but I found exactly two of the aforementioned bolts in the parts bins that came with it.

Are they supplied with the wing kit or the fuselage kit? If it's the wing kit, I'll have to check when I get home. I don't have the fuse kit yet. I did do the inventory for the wing kit so if those parts are listed in the inventory list then I can say they are included.

Thanks, but I am not saying Van's didn't include the parts. Did they include the correct parts?
I do not know what kit they supplied them in. Perhaps someone currently at this stage can comment.
If Van's has continued to supply the "wrong" hardware, or different than the plans, what Vic is seeing would have a common thread.

( typing while someone was answering. Good to know they supplied the correct hardware with that kit - Thanks Raymo! )

Always a drilled bolt for the -6

......

That may be what they provided, but the -6 plans on sheet 46 have always specified a drilled bolt.

The early plans called for a AN5-7 bolt, AN310-5 nut and a AN960-519 washer.

A later edit in 1997 changed it to a AN5-10 bolt and added the cotter pin.

In 2001 the number of washers call out was increased to 3.

A drilled bolt has always been specified for that location on the -6.
