ADVISORY CIRCULAR

AC No: 20-27D

Date: 6/22/90

Initiated
by: AIR-200

Subject: CERTIFICATION AND OPERATION OF AMATEUR-BUILT AIRCRAFT

1. PURPOSE. This advisory circular (AC) provides guidance
concerning the building, certification, and operation of
amateur-built aircraft of all types; explains how much
fabrication and assembly the builder must do for the aircraft to
be eligible for amateur-built certification; and describes the
Federal Aviation Administration (FAA) role in the certification
process.

2. CANCELLATIONS. Advisory Circular 20-27C, Certification and
Operation of Amateur-Built Aircraft, dated April 1, 1983, is
cancelled.

3. BACKGROUND. The Federal Aviation Regulations (FAR) provide
for the issuance of FAA Form 8130-7, Special Airworthiness
Certificate, in the experimental category to permit the operation
of amateur-built aircraft. Federal Aviation Regulations 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.

4. DEFINITION. As used herein, the term "office" means the FAA
Flight Standards District Office (FSDO), Manufacturing Inspection
District Office (MIDO), or Manufacturing Inspection Satellite
Office (MISO) that may perform the airworthiness inspection and
certification of an amateur-built aircraft.

5. FAA INSPECTION CRITERIA.

a. The amateur-built program was designed to permit
person(s) to build an aircraft solely for educational or


P S Advisory Circular # 20-27D Page: 2
02/05/97 15:39 AYCEHKT AYOPB32
Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 2 of 36 ================================

recreational purposes. The FAA has always permitted amateur
builders freedom to select their own designs. The FAA does not
formally approve these designs since it is not practicable to
develop design standards for the multitude of unique design
configurations generated by kit manufacturers and amateur
builders.

b. In the past, the FAA inspected amateur-built aircraft
at several stages during construction. These inspections were
commonly called precover inspections. The FAA also inspected the
aircraft upon completion, before the initial issuance of the
special airworthiness certificate, for the purpose of showing
compliance with FAR section 91.42(b) (new FAR section 91.319),
and again before issuance of the unlimited duration FAA Form
8130-7. After reassessing the need for these inspections, the
FAA in 1983 decided to perform only on inspection prior to
initial flight test.

NOTE: FAR Part 91 has been revised effective August 18,
1990. Both old and new FAR sections are referenced in this
AC.

c. Since 1983, FAA inspections of amateur-built aircraft
have been limited to ensuring the use of acceptable workmanship
methods, techniques, practices, and issuing operating limitations
necessary to protect persons and property not involved in this
activity.

d. In recent years, amateur builders have adopted a
practice whereby they call upon persons having expertise with
aircraft construction techniques, such as the Experimental
Aircraft Association (EAA) Technical Counselors (reference
paragraph 6. (a)) to inspect particular components, e.g., wing
assemblies, fuselages, etc., prior to covering, and to conduct
other inspections, as necessary. This practice is an effective
means of ensuring construction integrity.

e. 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) and are
authorized to charge for their services. These charges are set
by the DAR and are not governed by the FAA. The amateur-builder
may contact the local FAA office to locate a DAR.

f. In view of the foregoing considerations, the FAA has
concluded that safety objectives, relative to the amateur-built
program, can continue to be met by the use of the following


P S Advisory Circular # 20-27D Page: 3

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 3 of 36 ================================

criteria:

(1) Amateur builders should have knowledgeable persons
(i.e., FAA certificated mechanics, EAA Technical Counselors,
etc.) perform precover inspections and other inspections as
appropriate. In addition, builders should document the
construction using photographs taken at appropriate times prior
to covering. The photographs should clearly show methods of
construction and quality of workmanship. Such photographic
records should be included with the builder's log or other
construction records.

(2) The FAA inspector or DAR will conduct an
inspection of the aircraft prior to the issuance of the initial
FAA Form 8130-7 to enable the applicant to show compliance with
FAR section 91.42(b) (new FAR section 91.319). This inspection
will include a review of the information required by FAR section
21.193, the aircraft builder's logbook, and an examination of the
completed aircraft to ensure that proper workmanship has been
used in the construction of the aircraft. Also, the appropriate
operating limitations will be prescribed at this time in
accordance with FAR section 91.42 (new FAR section 91.319).

(3) An FAA inspector or DAR may elect to issue
amateur-built airworthiness certificates on a one-time basis to
the builder for showing compliance with FAR section 91.42(b) (new
FAR section 91.319) and continued operation under FAR section
21.191(g). Under this procedure, the aircraft will be inspected
by the FAA only once prior to flight testing. The airworthiness
certificate will be issued, but its validity will be subject to
compliance with the operating limitations. The limitations will
provide for operation in an assigned flight test area for a
certain number of hours before the second part of the limitations
becomes effective, releasing the aircraft from the test area.

6. DESIGN AND CONSTRUCTION.

a. Many individuals who desire to build their own aircraft
have little or no experience with respect to aeronautical
practices, workmanship or design. An excellent source for advice
in such matters is the EAA located in Oshkosh, Wisconsin. (See
appendix 1.) The EAA is an organization established for the
purpose of promoting amateur aircraft building and giving
technical advice and assistance to its members. The EAA has
implemented a Technical Counselors Program whose aim is to ensure
the safety and dependability of amateur-built aircraft. Most EAA
Technical Counselors are willing to inspect amateur-built
aircraft projects and offer constructive advice regarding

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 4 of 36 ================================

workmanship and/or design.

b. Any choice of engines, propellers, wheels, other
components, and any choice of materials may be used in the
construction of amateur-built aircraft. However, it is strongly
recommended that FAA-approved components and established aircraft
quality material be used, especially in fabricating parts
constituting the primary structure, such as wing spars, critical
attachment fittings, and fuselage structural members. Inferior
materials, whose identity cannot be established, should not be
used. The use of major sections (i.e., wings, fuselage,
empennage, etc.) from type certificated aircraft may be used in
the construction as long as the sections are in a condition for
safe operation. These sections are to be considered by the FAA
inspector or DAR in determining the major portion in FAR section
21.191(g), but no credit for fabrication and assembly would be
given the builder for these sections. It is recommended that
builders contact their local FAA office to coordinate the use of
such sections.

c. The design of the cockpit or cabin of the aircraft
should avoid, or provide for padding on, sharp corners or edges,
protrusions, knobs and similar objects which may cause injury to
the pilot or passengers in the event of an accident. It is
strongly recommended that Technical Standard Order (TSO) approved
or equivalent seat belts be installed along with approved
shoulder harnesses.

d. An engine installation should ensure that adequate fuel
is supplied to the engine in all anticipated flight attitudes.
Also, a suitable means, consistent with the size and complexity
of the aircraft, should be provided to reduce fire hazard
wherever possible, including a fireproof firewall between the
engine compartment and the cabin. When applicable, a carburetor
heat system should also be provided to minimize the possibility
of carburetor icing.

e. Additional information and guidance concerning
acceptable fabrication and assembly are provided in AC 43.13-1A,
Acceptable Methods, Techniques, and Practices - Aircraft
Inspection and Repair, and AC 43.13-2A, Acceptable Methods,
Techniques, and Practices - Aircraft Alterations. These
publications are available from the U.S. Government Printing
Office.

f. The builder should obtain the services of a qualified
aeronautical engineer or consult with the designer of purchased
plans or construction kits, as appropriate, to discuss the


P S Advisory Circular # 20-27D Page: 5

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 5 of 36 ================================

proposal if the aircraft design is modified during construction.

7. CONSTRUCTION KITS.

a. Construction kits containing raw materials and some
prefabricated components may be used in building an amateur-
built aircraft. However, aircraft which are assembled entirely
from kits composed of completely finished prefabricated
components, parts and precut and predrilled materials are not
considered to be eligible for certification as amateur-built
aircraft since the major portion of the aircraft would not have
been fabricated and assembled by the builder.

b. An aircraft built from a kit may be eligible for
amateur-built certification, provided the major portion has been
fabricated and assembled by the amateur builder. Kit owner(s)
may jeopardize eligibility for amateur-built certification under
FAR section 21.191(g) if they allow someone else to build the
aircraft. The major portion of such kits may consist of raw
stock such as lengths of wood, tubing, extrusions, etc., which
may have been cut to an approximate length. A certain quantity
of prefabricated parts such as heat treated ribs, bulkheads or
complex parts made from sheet metal, fiber glass, or polystyrene
would also be acceptable, provided the kit still meets the major
portion of the fabrication and assembly requirement, and the
amateur builder satisfies the FAA inspector or DAR that
completion of the aircraft kit is not merely an assembly
operation.

CAUTION: Purchasers of partially completed kits should
obtain all fabrication and assembly records from the
previous owner(s). This may enable the builder who
completes the aircraft to be eligible for amateur-built
certification.

c. Various material/part kits for the construction of
aircraft are available nationally for use by aircraft builders.
Advertisements tend to be somewhat vague and may be misleading as
to whether a kit is eligible for amateur-built certification. It
is not advisable to order a kit before verifying with the local
FAA office if the aircraft, upon completion, may be eligible for
certification as amateur-built under existing rules and
established policy.

d. It should be noted the FAA does not certify aircraft
kits or approve kit manufacturers. However, the FAA does perform
evaluations of kits which have potential for national sales
interest, but only for the purpose of determining if an aircraft


P S Advisory Circular # 20-27D Page: 6

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 6 of 36 ================================

built from the kits will meet the major portion criteria. A list
of these kits is maintained at the local FAA office for
information to prospective builders.

8. REGISTRATION AND MARKING INFORMATION. Federal Aviation
Regulations section 21.173 requires that all U.S. civil aircraft
be registered before an airworthiness certificate can be issued.
Federal Aviation Regulations Part 47, Aircraft Registration,
prescribes the requirements for registering civil aircraft. The
basic procedures are as follows:

a. A builder wishing to register an aircraft must first
obtain a registration number assignment (N-number) from the FAA
Aircraft Registry. (See appendix 1 for the address of the
Aircraft Registry.) This number will eventually be displayed on
the aircraft. It is not necessary to obtain a registration
number in the early stages of the project. Builders intending to
obtain a special number of their choice must submit a letter (see
appendix 2) listing up to 5 possible registration numbers
desired. Under FAR Part 47, a special registration number will
cost $10 and may be reserved for no longer than 1 year. Renewal
is necessary each year with an additional $10 fee. If a special
number is being requested along with registration, an additional
$5 fee is required. Although this reservation does not apply to
numbers assigned at random by the Aircraft Registry, it is
recommended that application for registration number assignment
in either case be made 60 to 90 days prior to completion of
construction.

b. To apply for either a random or special registration
number assignment, the owner of an amateur-built aircraft must
provide information required by the Aircraft Registry by properly
completing an Aeronautical Center (AC) Form 8050-88, Affidavit of
Ownership for Amateur-Built Aircraft (see appendix 3). The
affidavit establishes the ownership of the aircraft; therefore,
all aircraft information must be given. If the aircraft is built
from an eligible kit, the builder should also submit a signed
bill of sale from the manufacturer of the kit as evidence of
ownership. If AC Form 8050-2, Aircraft Bill of Sale, is used,
the word "aircraft" should be deleted and the word "kit" inserted
in its place. (See appendix 4.)

c. After receipt of the applicant's letter requesting a
special or random number assignment, the Aircraft Registry will
send a form letter to the applicant giving the number assigned
(this does not constitute registration of the aircraft), a blank
AC Form 8050-1, Aircraft Registration Application, and other
registration information. All instructions must be carefully

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 7 of 36 ================================

followed to prevent return of the application and delay in the
registration process.

d. The applicant must complete and return the white
original and green copy of the Aircraft Registration Application
(with N-number) to the Aircraft Registry as soon as possible,
accompanied with a fee of $5 by check or money order payable to
the FAA (see appendix 5). The pink copy of the application is to
be retained by the applicant and carried in the aircraft as
temporary authority to operate without registration for a maximum
of 90 days or until receipt of AC Form 8050-3, Certificate of
Aircraft Registration. If AC Form 8050-3 is not received in the
90-day period, the builder must obtain written authority from the
Aircraft Registry for continued operation. However, if the
recommendations in paragraph 8.a through 8.d above are followed,
the applicant should have received AC Form 8050-3 before the
airworthiness inspection.

9. IDENTIFICATION AND REGISTRATION MARKS. When applying for an
airworthiness certificate for an amateur-built aircraft, the
builder must show in accordance with FAR section 21.182 that the
aircraft displays the nationality and registration markings
required by FAR Part 45. The following is a summary of the FAR
Part 45 requirements:

a. The aircraft must be identified by means of a fireproof
identification plate that is etched, stamped, engraved, or marked
by some other approved fireproof marking as required by FAR
section 45.11. The identification plate must include the
information required by FAR section 45.13.

b. The identification plate must be secured in such a
manner that it will not likely be defaced or removed during
normal service, or lost or destroyed in an accident. Aircraft
built and certificated after March 7, 1988, must have the
identification plate located on the exterior either adjacent to
and aft of the rear-most entrance door or on the fuselage near
the tail surfaces and must be legible to a person standing on the
ground (reference FAR section 45.11.)

c. The name on the identification plate must be that of
the amateur builder, not the designer, plans producer, or kit
manufacturer. The serial number can be whatever the builder
wishes to assign, provided it is not the same as other aircraft
serial numbers.

d. The builder should refer to FAR sections 45.22 and
45.25, which define specific requirements for the location of


P S Advisory Circular # 20-27D Page: 8
02/05/97 15:39 AYCEHKT AYOPB32
Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 8 of 36 ================================

registration marks on fixed-wing aircraft. The location of
registration marks for non-fixed wing aircraft are specified in
FAR section 45.27. These registration marks must be painted on
or affixed by any means insuring a similar degree of permanence.
Decals are also acceptable. The use of tape which can be peeled
off, or water soluble paint, such as poster paint, is not
considered acceptable.

e. Most amateur-built aircraft are required to display
nationality and registration marks with a minimum height of 3
inches. However, if the maximum cruising speed of the aircraft
exceeds 180 knots calibrated air speed (207 miles per hour), the
registration marks must be at least 12 inches high. The builder
should refer to FAR section 45.29, which defines the minimum size
and proportions for nationality and registration marks on all
types of aircraft.

f. The registration marks displayed on the aircraft must
consist of the Roman capital letter "N" (denoting United States
nationality) followed by the registration number of the aircraft.
(Registration marks may not exceed five symbols following the
prefix letter "N".) These symbols may be all numbers (e.g.,
N-10000); one to four numbers and one suffix letter (e.g.,
N-1000A); or one to three numbers and two suffix letters (e.g.,
N-100AB). Any suffix letter used in the marks must also be a
Roman capital letter. The letters "I" and "O" may not be used.
The first zero in a number must always be preceded by at least
one of the numbers 1 through 9. In addition, the word
"experimental" must also be displayed on the aircraft near each
entrance (interior or exterior) to the cabin or cockpit in
letters not less than 2 inches nor more than 6 inches in height.

g. If the configuration of the aircraft prevents marking
in compliance with any of the above requirements, the builder
should contact an FAA office regarding approval of a different
marking procedure under FAR section 45.22(d). It is strongly
recommended that any questions regarding registration marking be
discussed and resolved with a local FAA inspector or DAR before
the marks are affixed to the aircraft.

10. CERTIFICATION STEPS. The following procedures are in the
general order to be followed in the certification process:

a. Initial Step. The prospective builder should contact
the nearest FAA office to discuss the plans for building the
aircraft with an FAA inspector. During this contact, the type of
aircraft, its complexity and/or materials should be discussed.
The FAA may provide the prospective builder with any guidance


P S Advisory Circular # 20-27D Page: 9

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 9 of 36 ================================

necessary to ensure a thorough understanding of applicable
regulations.

b. Registration. Detailed procedures are in paragraph 8
of this AC. This must be done before submitting an FAA Form
8130-6, Application for Airworthiness Certificate, under FAR
section 21.173 to an FAA inspector or DAR.

c. Marking. The registration number (N-number) assigned
to the aircraft and an identification plate must be affixed in
accordance with FAR section 21.182 and Part 45, Identification
and Registration Marking. Detailed procedures are in paragraphs
8 and 9 of this AC.

d. Application. The builder may apply for a special
airworthiness certificate by submitting the following documents
and data to the nearest FAA office or to the DAR.

(1) Federal Aviation Administration Form 8130-6 (see
appendix 6).

(2) Enough data, such as photographs or three-view
drawings, to identify the aircraft.

(3) A notarized FAA Form 8130-12, Eligibility
Statement - Amateur-Built Aircraft, certifying the major portion
was fabricated and assembled for education or recreation, and
that evidence is available to support this statement. Evidence
will be provided to the FAA Inspector or DAR upon request. (See
appendix 7.)

(4) A letter identifying the aircraft and the area
over which the aircraft will be tested should accompany the
application. (See appendix 8.)

11. AIRCRAFT INSPECTION. The applicant should be prepared to
furnish the following to the FAA inspector or DAR:

a. An aircraft complete and ready to fly except for
cowlings, fairings, and panels opened for inspection.

b. An Aircraft Registration Certificate, AC Form 8050-3,
or the pink copy of Aircraft Registration Application, AC Form
8050-1 (with N-number).

c. Evidence of inspections, such as logbook entries signed
by the amateur builder, describing all inspections conducted
during construction of the aircraft in addition to photographic


P S Advisory Circular # 20-27D Page: 10
02/05/97 15:39 AYCEHKT AYOPB32
Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 10 of 36 ===============================

documentation of construction details. This will substantiate
that the construction has been accomplished in accordance with
acceptable workmanship methods, techniques, and practices. It is
recommended that this evidence be documented in some form (e.g.,
the Service and Maintenance Manual available from the EAA).

d. A logbook for the aircraft, engine, and propeller to
allow for review of service records and recording of inspection
and certification by the FAA inspector or DAR.

12. FAA INSPECTION AND ISSUANCE OF AIRWORTHINESS CERTIFICATE.

a. After inspection of the documents and data submitted
with the application, the applicant should expect the FAA
inspector or DAR to inspect the aircraft. Upon a determination
that the aircraft has been properly constructed, the FAA
inspector or DAR may issue an FAA Form 8130-7, together with
appropriate operating limitations. The applicant should expect
the FAA inspector or DAR to verify that all required markings are
properly applied, including the following placard which must be
displayed in the cabin or the cockpit at a location in full view
of all passengers. (Placard not applicable to single-place
aircraft.)

"PASSENGER WARNING - THIS AIRCRAFT IS AMATEUR-BUILT AND DOES
NOT COMPLY WITH FEDERAL SAFETY REGULATIONS FOR STANDARD
AIRCRAFT"

b. Details concerning flight test areas are contained in
paragraph 13. The operating limitations are a part of the
airworthiness certificate and must be displayed with the
certificate when the aircraft is operated. It is the
responsibility of the pilot to conduct all flights in accordance
with the operating limitations, as well as the General Operating
and Flight Rules in FAR Part 91.

c. In the case of a limited duration airworthiness
certificate, upon satisfactory completion of operations in
accordance with FAR section 91.42(b) (new FAR section 91.319), in
the assigned test area, the owner of the aircraft may apply to
the local FAA office or a DAR for amended operating limitations
by submitting another FAA Form 8130-6, along with a letter
requesting amendment of operating limitations. Prior to issuance
of the amended limitations and a new FAA Form 8130-7, the
applicant should expect the FAA inspector or DAR to review the
flight log to determine whether corrective actions have been
taken on any problems encountered during the testing and that the
aircraft's condition for safe operation has been established.

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 11 of 36 ===============================

Reinspection of the aircraft may be necessary.

d. Refer to paragraph 13d. (1) and (2) for the processing
of unlimited duration airworthiness certificates.

13. FLIGHT TEST AREAS.

a. Amateur-built airplanes and rotorcraft will initially
be limited to operation within an assigned flight test area for
at least 25 hours when a type certificated (FAA-approved)
engine/propeller combination is installed, or 40 hours when a
noncertificated (i.e., modified type certificated or automobile)
engine/propeller combination is installed. Amateur-built
gliders, balloons, dirigibles and ultralight vehicles built from
kits evaluated by the FAA and found eligible to meet requirements
of FAR section 21.191(g), for which original airworthiness
certification is sought, will be limited to operation within an
assigned flight test area for at least 10 hours of satisfactory
operation, including at least five takeoffs and landings.

b. The desired flight test area should be requested by the
applicant and, if found acceptable by the FAA inspector or DAR,
will be approved and specified in the operating limitations. It
will usually encompass the area within a 25-statute mile radius
(or larger depending on the type of aircraft) from the aircraft's
base of operation or in a designated test area established by the
local FAA office. The area selected by the applicant and
submitted to the FAA for approval should not be over densely
populated areas or in congested airways, so that the flight
testing, during which passengers may not be carried, would not
likely impose any hazard to persons or property on the ground.
Advisory Circular 90-89, Amateur-Built Aircraft Flight Testing
Handbook, contains recommended procedures for the flight testing
of amateur-built aircraft. It is strongly recommended that
amateur builders obtain a copy of this AC and follow its
guidance.

c. The carrying of passengers will not be permitted while
the aircraft is restricted to the flight test area. It is
suggested that a tape recorder, for example, be used by the pilot
for recording readings, etc. Flight instruction will not be
allowed in the aircraft while in the flight test area.

d. In those instances where the unlimited duration special
airworthiness certificate was issued, the operating limitations
may be prescribed in two phases in the same document as follows:

(1) For the Phase I limitations, the applicant will


P S Advisory Circular # 20-27D Page: 12

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 12 of 36 ===============================

receive from the certificating FAA inspector or DAR all those
operating limitations, as appropriate, for the applicant to
demonstrate compliance with FAR section 91.42(b) (new FAR section
91.319) in the assigned test area. This would further include a
limitation requiring the owner/operator to endorse the aircraft
logbook with a statement certifying when the aircraft has been
shown to comply with FAR section 91.42(b) (new FAR section
91.319). The owner/operator may then operate in accordance with
Phase II.

(2) For the Phase II limitations, the applicant will
receive from the certificating FAA inspector or DAR all those
operating limitations, as appropriate, to the issuance of an
unlimited duration FAA Form 8130-7 for the operation of an
amateur-built aircraft. Appendix 9 contains a sample of typical
operating limitations that may be issued. For special
conditions, these may vary for each aircraft.

14. SAFETY PRECAUTION RECOMMENDATIONS.

a. All Aircraft.

(1) The pilot should become thoroughly familiar with
the brake tests, engine operation, and ground handling
characteristics of the aircraft by conducting taxi tests before
attempting flight operations. Liftoff is not permitted during
taxi tests without an airworthiness certificate.

(2) Before the first flight of an amateur-built
aircraft, the pilot should take precautions to ensure that
emergency equipment and personnel are readily available in the
event of an accident.

(3) Violent or acrobatic maneuvers should not be
attempted until sufficient flight experience has been gained to
establish that the aircraft is satisfactorily controllable
throughout its normal range of speeds and maneuvers. Those
maneuvers successfully demonstrated while in the test area may
continue to be permitted by the FAA when the operating
limitations are modified to eliminate the test area. All
maneuvers satisfactorily conducted are to be documented in the
aircraft logbook by the pilot.

(4) The operating limitations issued by the FAA
inspector or DAR will require the aircraft to be operated in
accordance with applicable air traffic control and general
operating rules of FAR Part 91 as they apply to amateur-built
aircraft. Those operators who plan to operate under Instrument


P S Advisory Circular # 20-27D Page: 13

Doc #: 20-27D CERTIFICATION AND OPERATION OF AMATEUR-BUILT
Effective: 06/22/1990 AIRCRAFT
============================ Text Page 13 of 36 ===============================

Flight Rules are alerted to the specific requirements under FAR
sections 91.115 through 91.129 (new FAR section 91.173 through
91.187).

(5) Depending on the intended operation under FAR Part
91, the following FAR sections may be applicable:

a. FAR Section 91.33(b) (new FAR section 91.205)
Visual Flight Rules (day).

b. FAR Section 91.33(c) (new FAR section 91.205)
Visual Flight Rules (night).

c. FAR section 91.33(d) (new FAR section 91.205)
Instrument Flight Rules.

(6) Unless authorization to deviate is obtained from
Air Traffic Control, any aircraft that will be equipped with a
Mode C transponder shall have a calibrated airspeed/static
pressure system to prevent an error in altitude reporting.
(Reference FAR section 23.1323 and 23.1325.) The Mode C
transponder must be tested and inspected per FAR section 91.172
(new FAR section 91.413).

(7) An emergency locator transmitter is required to be
on board by FAR section 91.52 (new FAR section 91.207) upon
release from the flight test area. Single-place aircraft are
exempt from this requirement in accordance with FAR section
91.52(f)(9) (new FAR section 91.207).

b. Rotorcraft. The appropriately rated rotorcraft pilot
should be aware of the following operating characteristics:

(1) Operators of rotorcraft having fully articulated
rotor systems should be particularly cautious of "ground
resonance." This condition of rotor unbalance, if maintained or
allowed to progress, can be extremely dangerous and usually
results in structural failure.

(2) Tests showing that stability, vibration, and
balance are satisfactory should normally be completed with the
rotorcraft tied down, before beginning hover or horizontal flight
operations.

15. AMATEUR-BUILT AIRCRAFT CONSTRUCTED OUTSIDE THE UNITED STATES
AND PURCHASED BY U.S. CITIZENS.

Effective: 06/22/1990 AIRCRAFT
============================ Text Page 14 of 36 ===============================

procedures for obtaining airworthiness certification for
amateur-built operations are as follows:

(1) The previous owner should have conducted or had a
condition/annual type inspection performed on the aircraft within
30 days of the new U.S. owner applying for certification. This
inspection shall be recorded in the aircraft records.

(2) The previous owner should obtain documentation
from their Civil Aviation Authority that verifies the aircraft
is/was originally certificated in that country as an
amateur-built, and that the aircraft meets the requirements of
FAR section 21.191(g). This documentation should be furnished to
the new owner.

b. The new owner of such aircraft shall present the FAA
inspector or DAR with a properly completed FAA Form 8130-6, along
with the following documentation:

(1) All letters and records of inspections called for
in paragraph 15.a. (1) and (2).

(2) Proper documentation of registration in accordance
with FAR section 47.

(3) A letter of request to accompany the FAA Form
8130-6.

c. The applicant should expect the FAA inspector or DAR
to:

(1) Conduct a thorough review of all documentation
called for under paragraphs 15 a and b.

(2) Determine the amateur-built eligibility of the
aircraft presented.

(3) Inspect the aircraft like any other amateur-built
aircraft, since these airworthiness certifications are considered
original.

(4) If the aircraft is found to be eligible and
inspection is satisfactory, issue the FAA Form 8130-7 with proper
operating limitations. If the required flight time has not been
met or there is some question regarding the aircraft's flight
capability, the certificating representative may require flight
testing.

(5) Advise that the condition inspection on the
aircraft can only be performed by the original builder.

16. REPAIRMAN CERTIFICATION. The aircraft builder may be
certificated as a repairman if the builder is the primary builder
of the aircraft and can satisfactorily prove requisite skill in
determining whether the aircraft is in condition for safe
operation. This certification can be obtained by making
application to the local FAA office after the satisfactory
completion of required flight hours in the test area. Each
certificate is issued for a particular aircraft. (See appendix
10.)
