Amateur Built Aircraft Reference Material
The Federal Aviation Regulations (14 CFR part 21) provide for the issuance of
FAA Form 8130-7, Special Airworthiness Certificate, in the experimental category
to permit the operation of amateur-built aircraft. Section 21.191(g)
defines an amateur-built aircraft as an aircraft, the major portion of which has
been fabricated and assembled by person(s) who undertook the construction
project solely for their own education or recreation. Commercially produced
components and parts which are normally purchased for use in aircraft may be
used including engines and engine accessories, propellers, tires, spring steel
landing gear, main and tail rotor blades, rotor hubs, wheel and brake
assemblies, forgings, castings, extrusions, and standard aircraft hardware such
as pulleys, bellcranks, rod ends, bearings, bolts, rivets, etc.
The FAA has designated some private persons to act in its behalf in the
inspection of amateur-built aircraft and the issuance of airworthiness
certificates. These persons are known as Designated Airworthiness
Representatives (DAR). The amateur-builder may contact the local FAA Flight
Standards District Office (FSDO) or Manufacturing Inspection District Office (MIDO)
for assistance. To find a DAR in your area refer to the on-line directory:
In the directory, MIDO (Manufacturing) DAR's are listed by state in the first
half of the directory and FSDO (Maintenance) DAR's are listed by state in the
second half. DAR's with the authority to inspect and certify amateur-built
aircraft will have the DAR Function Code "46" under their name.
The following Advisory Circulars (AC) are also necessary for the safe
implementation and advancement of amateur-built aircraft construction. Click on

Directives, This AC provides guidance and information to owners and
operators of aircraft concerning their responsibility for complying with
airworthiness directives (AD) and recording AD compliance in the appropriate
Ultralight Vehicle, This advisory circular provides
guidance to the operators of ultralights in the United States. It discusses the
elements which make up the definition of ultralight vehicles for the purposes of
operating under Federal Aviation Regulation (14 CFR part 103). It also discusses
when an ultralight must be operated as an aircraft under the regulations
applicable to certificated aircraft.
