Alright, I said as "part of airworthiness certificate", which is wrong.

It's not wrong. If you read an actual set of operating limitations,
it says right at the top, in limitation #1 (as required by FAA Order
8130.2d): These operating limitations are a part of the FAA Form
8130-7, special airworthiness certificate...

For rec.aviation.homebuilt, there sure seem to be a lot of people here
who don't seem to own a homebuilt aircraft...
