FAA form 337?

[Paul Lee]

Some equipment I installed mentions form 337 - for example VOR/LOC/GS receiver,
IFR GPS, etc., Is 337 required in a new kit project? It is for "Major repairs
and alterations".

Or does the DAR approve the whole package together?

Please advise any required procedures.

337 IS NOT required for experimental aircraft.

The way I understand it, form 337 records a deviation between a
particular aircraft or subassembly and its type certification data.
Homebuilts, by and large (there are exceptions), do not hold type
certification, so form 337 is neither required nor valid for them.

If anybody wants to hijack this thread, all they have to do is name a
series of homebuilt kit aircraft that generally carry standard
airworthiness certificates. I know of one...

Thanks, and best regards

No, homebuilts are type certificated under Part 21 as Experimental.

337's are not required for alterations to homebuilts. You are required to "notify"
the FAA of changes in the design (this will be in your operating limitations). No
A&P, DAR, or anything else is required.

No John, they are not. They do not have type certificates. What they
have are individual airworthiness certificates issued under 21.191. There
is no type certification of experimentals.

Nothing in part 43 (maintenance. preventive maintenance, rebuilding, and
alteration) applies to aircraft with experimental certificates. This is specifically
stated in 43.1(b). 337's don't apply to homebuilts.

The only thing that applies is that the limitations attached to the airworthiness
certificate will say to notify the FSDO for major alterations and require a 5
hour test period and also remind the owner to update the registration if the
engine /propeller make/model changes.

You had best get with the "experimental aircraft association" on that one,
Ron. :)

That's a contradiction. 14 CFR 21.21 and 14 CFR 21.181 are quite clear
on this. Experimental aircraft are "certificated," yes, but they don't
hold "type certificates."

Sorry Bob, I cheated.

You are mistaken, "Experimental" is a Type, under CFR 14 Part 21.

The difference is that an Experimental is not elidgeable for STC, but
"Normal Catagory" type airplanes are.

14CFR Part 43.1 Applicability... sez not applicable to experimental, etc., etc.

Yep, not applicable.

Well, a 337 is also used to record a Major Repair, but I think that
the PMI's figure that they already have enough work to stay busy.

Go figure,

Still doesn't matter. Part 43 doesn't apply to homebuilts. There's no reason
to notify the FAA about repairs.

[Jerry Springer]

Ron, I am not even sure that you need to notify FAA with the later operating
limitations. I just upgraded mine to the latest version and it only says
I must return to phase 1 for 5 hours after major modifications

Also the Schweizer 2-22CK. I built one.
