Obscure specs, or just copyrighted?

Obscure specs, or just copyrighted?

(OP)
Howdy all,

So I have a Sofrance (Safran Group) CMM that calls out connector type NSA 8676 #6 for connection to port NSA 8677 #6. I can find the NSA 8676 bobbins for sale, but I want to know more about this fitting and can find nothing in the way of specifications. Can anyone provide a copy of the spec or point me to the standards body that created it so I can get it from them if it's not freely available? Are these Airbus specs?

Thanks,

-Kirby

This one has stumped-the-chump... me [scratch, scratch, scratch]!?!?

The part numbers imply they may be SAFRAN proprietary...

NSA 8676

Number SAFRAN/SoFrance Aerospace... perhaps?

I like your taglines...

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

I did further searches and came up with "Norme Sud Aviation". So they may have been Sud Aviation standards. The fitting is an O-ring bobbin that mates a .500 hole to a .500 hole. The part I have has two of them and I was wondering if the two together were one fitting and the distance between them was a standard or (more likely) if each fitting was independent and the distance was as needed for the part.

OK... Norme Sud Aviation works for me...

I can't believe I stumped Wil. I'm marking this in my calendar...

And Sud Aviation is defunct so the lack of info is understandable. I think the fittings can be purchased, but I RE'd the ones that came with the part incase the next part didn't include them. Not exactly like what it came with, the original was slightly asymmetric with one end being ~.007 smaller, but I figured making them symmetric was a better idea.

Whilst Sud Aviation may be no more, "someone" should be covering their planes TCs and supporting the fleet ... or maybe they were surrendered ?

It's on the Airbus site under Standard Materials, it's an aerospatiale standard for a drum. The hydraulic fitting Kirby shared is somewhat similar but not identical.

kontiki99,

Thanks for responding. I looked at Airbus' site and it's, of course, massive. Could you guide me on drilling down to locate this standard materials section and the specific document? Does this need an Airbus login or subscription? I don't but my document librarian might.

Best Regards,

-Kirby

In the Airbus site, I went to a tile called Associated data, then airnavX, search on NSA8687 in the large "search on content" field and it retrieves different NSA8687 hits, they pretty much all deliver a pdf symbol that pulls up the spec, or you can scroll down to SM (for Standards Manual) specification NSA8687.

The browser applet web site support tools are a random mess to work with. I don't know why. We're either laughing at them or cursing at them depending on the urgency.

So I went to Airbus.com. This is the corporate website and I didn't see a tile called associated data. Is there a separate site for Airbus documents. Can you provide a link to that web page? I'm not even getting started on which tentacle of this octopus I'm trying to slay. I did a search for associated data and got hundreds of hits. I then did a search for airnavX and got one hit, https://www.airbus.com/newsroom/news/en/2018/02/ne... which wasn't very useful. And finally NSA8687 didn't find anything, which is where I started.

Again, is this a subscription site different from the corporate site?

Thanks,

-Kirby

kirby,

you should be aware of the difference between an octopus and a hydra. I think you're wrestling with a hydra !!??

that, or tilting at windmills ...

KirbyWan:

The site you want is w3.airbus.com to which my company has access permissions as it is a requirement for access. Unfortunately those access permissions contain an NDA that prevents me from just handing you the Standards Manual. I do not know if the Standards Manual is available through any other means as when we need it we use our w3.airbus.com permissions.

If you can gain access, kontiki99 has provided the path to follow.

RE: Obscure specs, or just copyrighted?

debodine,

Thank you. I expected as much and wouldn't want anyone to violate a NDA. A decade ago someone asked for the FCBS for the DC-10 and I had a copy and provided it, and Boeing slapped my wrist for it. We should take the old mil-specs and create open source specs based on them. I expect all the standards orgs would have an eye twitching conniption fit. I feel my design based on a physical article is close enough to satisfy my needs. I can live without the completeness of having the original standard it was based on, though it will feel like an empty place in my soul.

Thanks everyone for an informative thread.
