Subject: COMMERCIAL ASSISTANCE DURING CONSTRUCTION OF
AMATEUR-BUILT AIRCRAFT
1. PURPOSE. This advisory circular (AC) explains current
Federal Aviation Regulations (FAR) and Federal Aviation
Administration (FAA) policy for the fabrication and assembly of
amateur-built aircraft. It provides information and guidance to
persons involved in the construction of amateur-built aircraft,
the manufacture of kits designed to be assembled into aircraft by
amateur-builders, builders of aircraft fabricated from plans for
certification as amateur-built, and persons providing assistance
to amateur-builders. Like all AC material, this AC is not
mandatory and does not constitute a regulation. It is issued for
guidance purposes and to outline a method of compliance with the
applicable FAR. In lieu of following this method without
deviation, a person may elect to follow an alternate method,
provided the alternate method is also found by the FAA, to be an
acceptable means of complying with the requirements of the FAR.
Since the method of compliance presented in this AC is not
mandatory, the terms "shall" and "must" used herein apply only to
a person who chooses to follow this particular method without
deviation. This AC does not change regulatory requirements and
does not authorize changes in, or deviations from, regulatory
requirements.

f. FAA Order 8130.2, Airworthiness Certification of Aircraft
and Related Products.
3. BACKGROUND.
a. The FAR provides for the issuance of a special
airworthiness certificate in the experimental category for the
purpose of operating amateur-built aircraft. Title 14 CFR part
21, section 21.191(g), defines an amateur-built aircraft as "an
aircraft THE MAJOR PORTION of which has been FABRICATED AND
ASSEMBLED BY PERSONS who undertook the construction project
SOLELY FOR THEIR OWN EDUCATION OR RECREATION" (emphasis added).
b. The FAA, in partnership with the Experimental Aircraft
Association (EAA) and the Small Aircraft Manufacturers
Association (SAMA), saw a need to address the practice of
fabrication and assembly of amateur-built aircraft for profit.
The aircraft were designed as kits and/or plans-built, with the
intent that they would be constructed by amateur-builders for
their own education or recreation.
4. DEFINITIONS. As used in this advisory circular, the
following definitions apply:
a. Aircraft Evaluation. The evaluation performed for the
purpose of determining if a specific amateur-built aircraft meets
the major portion requirement of section 21.191(g).
b. Builder Center. A place where amateur-builders can
obtain instruction, help, and support during construction of
their aircraft.
c. Commercial Assistance. Assistance in the building of an
amateur-built aircraft in exchange for compensation. This does
not include one builder helping another.
d. Compensation. Payment by the amateur-builder applicant
in cash, services, or other tender, to any person who provides
assistance on a commercial basis in the building of an aircraft.
e. Checklist. The FAA Form 8000-38, Fabrication/Assembly

============================ Text Page 3 of 23 ================================
Operation Checklist, is used by the FAA as an aid in determining
if a manufacturer's aircraft kit meets the major portion
requirements of section 21.191(g). It is also used for
determining if a completed aircraft is eligible for certification
as an amateur-built aircraft (sample in appendix 1).
f. Kit-Built Aircraft. An aircraft that is constructed from
a manufactured kit that may include some major sub-assemblies
and/or pre-assembled components.
g. Kit Evaluation. An evaluation by the FAA to determine if
an aircraft built from, and according to, the kit instructions
will meet the major portion requirement of section 21.191(g).
h. Letter of Eligibility. A letter provided by the FAA to
an aircraft kit manufacturer advising that the aircraft kit
requested to be evaluated meets the major portion requirement of
section 21.191(g).
i. Major Portion. As related to a special airworthiness
certificate issued for the purpose of operating amateur-build
aircraft, major portion means that when the aircraft is
completed, the majority of the fabrication and assembly tasks
have been performed by the amateur builder(s) who submit the
application for certification.
j. Person. An individual, firm, partnership, corporation,
company, association, joint-stock association, or governmental
entity. It includes a trustee, receiver, assignee, or similar
representative of any of them.
k. Plans-Built Aircraft. An aircraft that is constructed
exclusively from plans/blueprints without the aid of purchased
major sub-assemblies or preassembled kit components. This also
includes aircraft of a builder's original design.
l. Unacceptable Commercial Assistance. Any commercial
assistance that reduces the work performed by the amateur-builder
to less than the major portion of the aircraft construction.
5. EVALUATION OF KITS, COMPLETED KIT-BUILT, AND PLANS-BUILT
AIRCRAFT. The evaluation to determine compliance with the major
portion construction requirement of the FAR is usually performed
by an FAA Aviation Safety Inspector (ASI) from a Manufacturing
Inspection District Office (MIDO) or a Flight Standards District
Office (FSDO). Additionally, a Designated Airworthiness
Representative (DAR) may be authorized to evaluate a completed
plans-built aircraft intended for certification as an
P S Advisory Circular # 20-139 Page: 4

Doc #: 20-139 COMMERCIAL ASSISTANCE DURING CONSTRUCTION OF
Effective: 04/03/1996 AMATEUR-BUILT AIRCRAFT
============================ Text Page 4 of 23 ================================
amateur-built.
a. Initial Evaluation of Kits.
(1) Aircraft kit manufacturers requesting a kit
evaluation should submit a letter to the local FAA Manufacturing
office. The purpose of the evaluation is to determine if the
completed aircraft is capable of meeting the major portion
requirements of section 21.191(g).
(2) When the kit is evaluated using the checklist as a
guide and found to comply with the major portion requirement of
section 21.191(g), a Letter of Eligibility is sent to the kit
manufacture. The kit is then acceptable to be included in the
Listing of Eligible Amateur-Built Aircraft Kits. This letter
SHOULD NOT be construed to mean the kit or its manufacturer is
FAA certified, certificated, or approved, and it is not
appropriate to represent it as such.
(3) The listing is published by the FAA's Engineering
and Manufacturing Branch, AFS-610, P.O. Box 25082, Oklahoma City,
OK 73125, telephone number, (405) 954-4103. This information is
also available in electronic format through Fed World in
Springfield, VA by calling (703) 487-4608 or through the internet
via: http//www.fedworld.gov/. The purpose of the listing is to
assist the amateur-builder, the ASI, or the DAR by eliminating
the duplication or evaluations for the major portion
determination.
(4) If the kit manufacturer later offers an option or
makes changes to the kit that decreases the amount of fabrication
and assembly required by the builder, the manufacturer should
request a new Letter of Eligibility. The kit manufacturer would
provide a revised checklist and a description of the option or
change to the FAA with drawing and/or photos as necessary. If
the FAA determines that the revised kit still meets the major
portion requirement, the FAA will issue a new Letter of
Eligibility for the amended checklist without conducting a
physical inspection or complete re-evaluation of the kit. If the
FAA determines that the option or change was of sufficient
magnitude, a physical inspection and re-evaluation of the kit
will be performed.
b. Completed Kit-Built Aircraft. When a kit has been
evaluated and published in the listing of eligible amateur-built
aircraft kits, and no commercial assistance was used in the
construction of the aircraft using the evaluated kit, the ASI or
DAR will not be required to make another major portion rule

Doc #: 20-139 COMMERCIAL ASSISTANCE DURING CONSTRUCTION OF
Effective: 04/03/1996 AMATEUR-BUILT AIRCRAFT
============================ Text Page 5 of 23 ================================
determination for the completed aircraft.
c. Plans-Built Aircraft.
(1) During final inspection for compliance with section
21.191(g), a plans-built aircraft must be evaluated using the FAA
Form 8000-38 as a guide. If the builder intends to utilize
commercial assistance, the FAA Form 8000-38 can be submitted to
the FAA prior to construction, listing the tasks or processes for
which the commercial assistance is proposed. It should also show
the intended fabrication and assembly tasks the builder will
perform. On the basis of this pre-construction checklist, a
builder of a plans-built aircraft should be able to obtain an
evaluation in writing from the ASI or DAR of the effect that the
proposed commercial assistance will have on the major portion
requirement for the completed aircraft.
(2) A person may provide commercial assistance to a
builder of a plans-built aircraft or non-evaluated kit. This
assistance or task must be listed in the KIT MANUFACTURER column
on the checklist when the completed aircraft is presented for
evaluation/certification to the ASI or DAR.
6. COMMERCIAL ASSISTANCE NOT REQUIRING RE-EVALUATION OF THE
COMPLETED AIRCRAFT.
a. Commercial instructional assistance may be obtained by
the amateur builder in the fabrication or assembly of specific
parts and the completion of certain tasks or processes involved
in the construction of the aircraft. During all instructional
activity, the amateur-builder must be present to accomplish the
tasks and all subsequent fabrication and assembling of parts for
which commercial instruction is being rendered. Tasks completed
by the amateur-builder would be identified on the FAA Form
8000-38 under AMATEUR or in the assembly manual. For example,
assume fabrication of the wing ribs is listed on the checklist or
in the assembly manual as a task required to be completed by the
amateur-builder. Instructional activity could be provided to
build the first few ribs with the remainder to be completed by
the amateur-builder.
b. Commercial assistance may be obtained for non-checklist
items on a kit that has been evaluated by the FAA. A
non-checklist item is a task or process that is not listed in the
checklist. These items also include painting and the
installation of interior upholstery or avionics beyond basic
regulatory requirements. Such a task or process would not be
required to be personally completed by the amateur-builder for
P S Advisory Circular # 20-139 Page: 6
02/05/97 15:44 AYCEHKT AYOPB32
Doc #: 20-139 COMMERCIAL ASSISTANCE DURING CONSTRUCTION OF
Effective: 04/03/1996 AMATEUR-BUILT AIRCRAFT
============================ Text Page 6 of 23 ================================
the aircraft to receive an airworthiness certificate under
section 21.191(g).
c. The amateur-builder is not expected to have fabricated
every component that makes up the completed aircraft.
Non-checklist items include the fabrication of the engines,
propellers, wheels and brake assemblies, and standard aircraft
hardware. The installation of these items may be required to be
accomplished by the builder if they are checked in the AMATEUR
column on the checklist.
7. Commercial Assistance Requiring Re-evaluation of the
Completed Aircraft. If commercial assistance other than that
described in paragraph 6 is performed on the items listed in the
checklist under AMATEUR, on a evaluated kit, the major portion
evaluation previously performed by the FAA will be invalid for
that specific aircraft project. Consequently, it may result in a
complete re-evaluation of the fabrication and assembly of that
aircraft. This could put the amateur-built status of the
aircraft in jeopardy. In other words, the aircraft will be
treated as a non-evaluated kit and subject to complete evaluation
by the FAA when presented for certification as an amateur-built
aircraft. The builder may want to obtain a pre-construction
evaluation of proposed commercial assistance in writing from the
ASI or DAR to preclude certification problems at the completion
of a project.
8. Commercial Assistance on Incomplete Aircraft. Commercial
assistance does not include the instance where an incomplete
aircraft is sold to another builder and the second or subsequent
builder completes the aircraft. In such a case, the work
performed by the first builder will count toward completion of
the major portion by the second builder. The second or
subsequent builder should obtain as much detailed information and
documentation, e.g., logbooks, material receipts, pictures, etc.,
from the original builder as possible. This information will be
helpful in the FAA's determination for the major portion
requirement of the aircraft and eligibility of the subsequent
builder to meet the requirement for repairman certification under
section 65.104. The second builder may not be eligible for a
repairman certificate under section 65.104, unless it can be
shown to the satisfaction of the FAA that the individual has the
requisite skill to determine whether the aircraft is in a
condition for safe operation.
9. Non-Evaluated Kit Aircraft. An aircraft constructed from a
non-evaluated kit must be evaluated upon completion for
compliance with section 21.191(g), by the ASI or DAR using the
P S Advisory Circular # 20-139 Page: 7

============================ Text Page 7 of 23 ================================
procedures in the FAA Order 8130.2, Airworthiness Certification
of Aircraft and Related Products, and the FAA Form 8000-38, as a
guide.
10. ADDITIONAL INFORMATION. The FAA Form 8130-12, Eligibility
Statement, is one of the forms required to be submitted by the
applicant for a special airworthiness certificate for the purpose
of operating an amateur-built aircraft. It includes sections for
the registered owner and aircraft information along with the
applicant's declaration certifying that all statements and
answers are complete and true. It also provides notice of the
potential penalty that could be applied if false or fraudulent
statements are made. A sample of the FAA Form 8130-12 is located
in appendix 2.
11. INFORMATION SUPPLIED BY INDUSTRY TO PROSPECTIVE CUSTOMERS.
Kit manufacturers are encouraged to include a document explaining
the intent and purpose of the amateur-built rule in their
information packages. Prospective customers would then be made
aware of their responsibility and limitations under the FAR. The
information package should summarize the process used to
determine kit eligibility and the inspection of the completed
aircraft. It should also advise potential builders of the
statement they must sign certifying that they fabricated and
assembled the major portion of the aircraft. Additionally, the
customer should be advised of the need for and the availability
of flight training, as well as the value of participation in the
EAA Flight Advisor Program.
12. INFORMATION SUPPLIED BY INDUSTRY TO PURCHASERS. Kit
manufacturers are encouraged to include a copy of the
amateur-built regulation and to advise the purchaser of the
requirement for the applicant to certify that they fabricated and
assembled the major portion of the aircraft for their own
education or recreation. In addition to the aircraft assembly
manual, the kit manufacturer should reference this AC regarding
acceptable commercial assistance and the use of a builder center
for help and instruction during construction of an aircraft. The
manufacturers should inform purchasers of the help available to
them through various EAA programs, including: EAA
Chapters, Technical Counselors, and Flight Advisors.
