For more information on the FAA 51% rule (FAR 21.191(g)) and other legal/ general guidelines to completing your home built air craft, please see the home builder’s checklist on the EAA’s website. If you would like to read more in depth about FAR 21.191(g) please visit the FAA’s  AC 20-27G – Certification and Operation of Amateur-Built Aircraft.


“Fundamental to considering the purchase and/or construction of an experimental amateur-built aircraft is an understanding and observance of the regulation that makes possible FAA-authorized inspection and certification in this category (FAR21.191(g)). In simplest terms, the regulation states: (1) that such aircraft must have been constructed with the sole intent being the education and recreation of the builder or builders, and (2) that the builders must have executed the majority portion (at least 51%) of the construction of the airframe (that is, excluding engine, propeller, avionics, upholstery, and paint). FAA Advisory Circular (AC 20-139) reaffirms the intent and legal basis of this regulation.” (
