Anyone familiar with NAS1834, NAS 1832 and NAS1836?

When I design with NAS hardware, it is because I have bags and bags of
them on hand and I'm trying to use them up. All other hardware is COTS
items from Aircraft Spruce or McMaster-Carr, or can be made from
common materials according to simple drawings.

Thanks, Bob K.

Yes, on the face of it that makes sense, however, the designer is
doing this on a pro-bono basis, and he's very busy with no time to
entertain changes.

It would be great if we could use COTS parts, but we must use aircraft
parts with complete traceability and manufacturer certs to meet the
approval of the engineer and Transport Canada.

If we could build it COTS it would have been done 2 years ago. It's
extremely frustrating.

Potted inserts are not common COTS items, however, the designer should
have no problem substituting with a commercial (Think Rosan) style
insert.

Have your designer contact me, I'll hook him up with parts that are
available yet meet commercial/mil specs.

Hi;

Thae designer does have a problem substituting non-aircraft parts.
sigh

Do you have any documentation for the substitutes you know about?

Martin, did you ever find a supply for your NAS1834 inserts? We manufacture all NAS1832 - NAS1834 inserts and can do custom lengths and sizes.

I tried these folks for NAS replacement bolts for Pawnee wheels, very
reasonable when I told them I needed 1000's of similar part numbers at
work. I deal with a lot of vendors, these guys are so good I had them
added to my companies approved buyer list. Anyone that has stock on
long titanium bolts is a vendor to remember.

Links below show a large number of records for the two NAS numbers you
had problems with. Call Tim, he can help with P&D quote:
