Amateur-Built Aircraft Kits

The FAA performs evaluations to determine if an aircraft built from a kit will meet 14 Code of Federal Regulations (CFR) section 21.191 (g), "major portion" requirement. The FAA does not certify, certificate, or approve aircraft kits. Also, the FAA does not approve kit manufacturers.

In addition, we welcome Amateur-Built Aircraft Kit-Listing related written inquires to:

Federal Aviation Administration
