Ready for final assembly

[PapuaPilot]

As far as the N number. I got a new number and which our anniversary and first initials.

If you are asking about the 'X', I talked with three FAA guys at the local FISDO, including the head guy. We looked at FAR 45.22 and 45.23 together. They agreed that it would be acceptable to use the 'X' in the N number and that it won't be necessary to put the 2" 'Experimental' label on the plane. The portion I wanted them to clarify in 45.22 was the statement about an "aircraft with the same external configuration as an aircraft built at least 30 years ago". They agreed that my Kitfox 5 would have the same external configuration as an early model Kitfox.

I don't think the DAR will disapprove it. If I'm not mistaken they use FARs and Advisory Circulars as a basis for doing the C of A. ACs are informational but not mandatory or regulatory, only the FARs are law. I already have my FISDOs approval to do this and they say it lines up with FARs.

In a nutshell FAR 45.22 allows you to use an 'X' under certain qualifying situations (which a KF meets). This is all that is needed to deem your plane experimental. FAR 45.23 says if you ONLY have the letter 'N" (i.e. IF YOU DON'T have an 'X') in your registration number then you MUST have the 2" 'Experimental" label.

Even so, here is what AC 45-2D says:

(2) You may insert the symbol (“C,” standard; “R,” restricted; “L,” limited; or “X,” experimental or provisionally certificated) appropriate to the airworthiness certificate of the three types of aircraft listed below. The symbol may be placed between the nationality designation and the registration number, for example, NX1234.
(a) A U.S.-registered aircraft built at least 30 years ago,
(b) A U.S.-registered aircraft with the same external configuration as an aircraft built at least 30 years ago that is operating under a special airworthiness certificate as an exhibition aircraft, or
(c) An amateur-built aircraft with the same external configuration as an aircraft built at least 30 years ago.

I am now imagining some of you updating your N numbers and removing the Experimental sticker.

Here is an example of a NX regitered plane that some of you might recognize.

I hadn't thought about kitfox being 30 years old already. Good job on the research.

Check the last para on this faa.gov page. It states:

The FAA no longer issues numbers beginning with NC, NX, NR, or NL. On some older aircraft, these numbers may be displayed in accordance with FAR Part 45.22.

How is your FSDO getting around this statement? I was all excited and stuff and the feds are still sending conflicting statements!

[PapuaPilot]

I don't see where the conflict is. FAR 45.22 defines what "some older aircraft" are. The Kitfox is over 30 years old and qualifies according to FARs and my agreed with the statement FSDO.

If the DAR doesn't like my N number I will go back to the FSDO and ask again. I will find out in a couple weeks when I have the DAR inspect my plane.

I have a friend with an E-AB Super Cub who did the same thing and he is from Arizona.

You need to ask your DAR now

Your DAR will be from the MIDO office. The Manufacturing part of the FAA
may not think the same as your FSDO.

EAB aircraft are no longer certified by FSDO DARs

In My area The Oklahoma City MIDO you can, on a Kitfox
put a NX on the aircraft. It is not required to be on the registration certificate.

Keep us posted Papua. I like the NX number just want to make sure the process is right so the feds can't complain!
By the way - Nice looking KF V!
Bought a KF V project recently and hope to start covering next spring.
