My Series 5 qualifies for Sport pilot. I assigned the gross weight a value

of 1320 lbs. As builder, I can do that.

I purchased a KitFox in January. Prior to buying it, I contacted the FAA and had them send me, on a CD, all of the paperwork that they had on file for the airplane. This included all of the airworthiness certificate applications, a copy of the airworthiness certificate itself, the operating limitations, the registration, etc. etc. etc. Bunch of paperwork.

NOWHERE in all of that paperwork was there any mention of the gross weight of the aircraft.

I asked the builder about that, and he said, "Well, everybody just knows that the gross weight of a Model IV-1200 is 1200 lbs." I said, "Sure, but where does it actually SAY that?" He didn't know.

So, my question is, where is the gross weight of an experimental aircraft actually stated or assigned? I was under the impression that the DAR needed to approve the gross weight that is requested, but there is no evidence in the paperwork that he did that. What am I missing?

Thanks.

Nick,
I believe that you are right. Nothing the FAA has says what the gross
weight for your plane.

BUT, you need to have weight and balance info in your plane in case you have
a ramp inspection. That says what the gross weight is. I think that there
is another place in YOUR paper work that is supposed to state the gross
weight.

Now you should get some corrections of what I said.

I think this is a no brainer. You make out a new weight and balance. Then visit your friendly FSDO and take all your current paper work in with log books and tell them you want to update your paperwork. They will do the paper work and when it comes time to assign a gross weight of the aircraft they will take the info off the weight and balance. If it says 1320 that is what they will put down on the paperwork.

You are good. When you certificate you have two options:
Experimental Light Sport ( only till Jan 0Cool
Experimental Amateur Built

In your limitations at the end of Phase 1 you will be required to make a log entry listing gross weight and several speeds. This is what will limit you.
If you log more than 1320 you cannot reduce later,but you can go back into Phase 1 and test to go higher.
I should finish my Model 7 in Aug and will go ELSA.

Lowell,
I thought it was, but some investigation led me to the conclusion that it is
NOT a requirement. It is a field on some - but not all - of the data plates
that you can buy.

From FAR 45:


§ 45.11 General.
(a) Aircraft and aircraft engines. Aircraft covered under §21.182 of this chapter must be identified, and each person who manufacturers an aircraft engine under a type or production certificate shall identify that engine, by means of a fireproof plate that has the information specified in §45.13 of this part marked on it by etching, stamping, engraving, or other approved method of fireproof marking. . . .

§ 45.13 Identification data.(a) The identification required by §45.11 (a) and (b) shall include the following information:

(1) Builder's name.

(2) Model designation.

(3) Builder's serial number.

(4) Type certificate number, if any.

(5) Production certificate number, if any.

(6) For aircraft engines, the established rating.

(7) On or after January 1, 1984, for aircraft engines specified in part 34 of this chapter, the date of manufacture as defined in §34.1 of that part, and a designation, approved by the Administrator of the FAA, that indicates compliance with the applicable exhaust emission provisions of part 34 and 40 CFR part 87. Approved designations include COMPLY, EXEMPT, and NON-US as appropriate.

(i) The designation COMPLY indicates that the engine is in compliance with all of the applicable exhaust emissions provisions of part 34. For any engine with a rated thrust in excess of 26.7 kilonewtons (6000 pounds) which is not used or intended for use in commercial operations and which is in compliance with the applicable provisions of part 34, but does not comply with the hydrocarbon emissions standard of §34.21(d), the statement “May not be used as a commercial aircraft engine” must be noted in the permanent powerplant record that accompanies the engine at the time of manufacture of the engine.

(ii) The designation EXEMPT indicates that the engine has been granted an exemption pursuant to the applicable provision of §34.7 (a)(1), (a)(4), (b), (c), or (d), and an indication of the type of exemption and the reason for the grant must be noted in the permanent powerplant record that accompanies the engine from the time of manufacture of the engine.

(iii) The designation NON-US indicates that the engine has been granted an exemption pursuant to §34.7(a)(1), and the notation “This aircraft may not be operated within the United States”, or an equivalent notation approved by the Administrator of the FAA, must be inserted in the aircraft logbook, or alternate equivalent document, at the time of installation of the engine.

(Cool Any other information the Administrator finds appropriate. . . .

Since homebuilts are not certificated planes, it looks like only the first three apply to us.
