Appendix 2

COMMONWEALTH OF AUSTRALIA - SPECIAL REQUIREMENTS SECTION 1 - INTRODUCTION. A new bilateral agreement between Australia and the United States (US) came into effect by the Exchange of Notes in December 1974 and June 1975 and superseded the agreement of 1959 relating to the reciprocal acceptance of aeronautical products. The manner in which this agreement will be implemented is described below.

A. Administration and Procedures The procedures which must be followed to obtain Australian certification are dealt with in the current issue of Part 100 of Australian Air Navigation Orders.

(2) A US Export Certificate of Airworthiness for export to Australia (or agreed alternative) with pertinent data will be required in connection with any Class I product and engine modules exported from the United States to Australia. Class II and Class III products to be eligible for installation on certificated civil aircraft registered in Australia must be processed in accordance with the applicable provisions of Part 21 of the United States Federal Aviation Regulations.

(3) Where the issue of an Export Certificate of Airworthiness is relevant, the certificate shall be issued within a period of 90 days or 50 operating hours, whichever is the lesser period, immediately preceding the date of application for Australian certification or validation, as appropriate, except as otherwise acceptable to Australia in a particular case. The Export Certificate of Airworthiness shall be accompanied by a document

e.g., aircratt logbook), furnished by the applicant, which contains entries identifying those applicable FAA Airworthiness Directives (AD's) with which compliance has been achieved. This document shall also identify those AD's containing repetitive compliance requirements, and when compliance is next due to be satisfied. All applicable FAA AD's must have been complied with prior to issuance of the US Export Certificate of Airworthiness.

(4) The applicant for a US Export Certificate of Airworthiness is also responsible for satisfying all other Australian Special Requirements (identified in section 2), as appropriate, for the particular product being exported to Australia and all applicable sections of FAR 21, Subpart L, before the US Export Certificate of Airworthiness can be issued.

(5) Copies of Australian Air Navigation Orders may be perused at the various regional offices of the Federal Aviation Administration or at the office of the Transport Attache, Embassy of Australia, 160- Massachusetts Avenue, N.N., Washington, D.C. 20036, or may be obtained by mail from the Secretary, Department of Transport, Box 18390, G.P.O. Melbourne, Victoria 3001, Australia.

Appendix 2 B. Acceptance of Aircraft

(1) In accordance with paragraph (4) of the Australia/Us bilateral agreement, an aircraft exported to Australia must comply with the Section of Air Navigation Orders Part 10l specifies an acceptable basis for type certification against the CAR's or FAR's, lists certain additional validation requirements and requires compliance to be demonstrated with all applicable Airworthiness Directives issued by the FAA and the Australian Department of Transport. In addition, documentation requirements are specified with respect to first-of-type and subsequent aircraft, with provision for certain additional data relating to service history to be supplied in the case of used aircraft.

(2) Australia will require to become conversant with the design of all fixed wing aircraft in excess of 5700 kg (12,566 lbs.) weight, and all multi-engine rotorcraft offered for Australian certification. Additionally, the Department of Transport may require to evaluate certain other aircraft which have unusual design features. The Department of Transport may then issue special conditions to cover certain features which would otherwise not meet the standards implicit in the Australian Air Navigation Orders.

(3) Once the Australian standard for certification has been determined, and, where necessary, Australian special conditions have been notified, Australia will in accordance with paragraph 9(h) (ii) of the Australia/US bilateral agreement accept aircraft and rotorcraft to the standard defined in these special conditions, together with the applicable FAA Airworthiness Directives and Australian Airworthiness Directives while they continue in production. Modifications to the aircraft may also be made provided the requirements used as the basis of Australian certification are complied with, or alternatively that the Department of Transport otherwise agrees that the modifications made are acceptable.

(4) Aircraft may be issued with Australian certificates of airworthiness in one or more of the following categories:

Transport;

Normal;

Utility;

Acrobatic;

Agricultural;

Developmental; and Special.

The Sections of Air Navigation Orders Part 101 relevant to civil aircraft constructed in the United States of America, its territories and possessions and exported to Australia are:

There are other Sections of Air Navigation Orders relating to aircraft designed against the British Civil Airworthiness Requirements, while the requirements for the Special Category are advised as special conditions to suit individual cases not provided for in the other categories.

C. Acceptance of Engines, Auxiliary Power Units and Propellers

(1) Aircraft engines, auxiliary power units and propellers which are exported to Australia as spares - i.e., not as parts of a particular aircraft - to be eligible for use on Australian aircraft must comply with the type design, be new or newly overhauled as defined in Part 21 of the United States FAR's and have a relevant logbook. Before installation in, or fitment to, an aircraft in Australia, such products are required to conform with any applicable Australian Airworthiness Directives.

(2) A United States Export Certificate of Airworthiness will be accepted as evidence that an engine, auxiliary power unit or propeller conforms with the type design and is either new or newly overhauled as the case may be.

Page 21OCROpen in PDF

Appendix 2 Engines, auxiliary power units and propeller need not incorporate modifications or manufacturers' service documents made mandatory by Australian Airworthiness Directives prior to export of the product to Australia. However, since it may be difficult to determine in Australia whether the product complies with the mandatory documents, information as to the modification status of a particular product would be of help to the Australian user. An appropriate statement either in a logbook or separately issued by the person or organization issuing the United States export certificate of airworthiness will be accepted as evidence of the modification status.

D. Acceptance of Appliances and Components

(1) Items classified as Class II and Class III products by FAR 21 (Subpart L, Section 21.321) and which are exported to Australia as spares -

i.e., not as parts of a particular aircraft - must conform to the type design and must be new or newly overhauled as defined in FAR 2l in order to be eligible for use on Australian aircraft. Before installation in, or fitment to, an aircraft in Australia, such products are required to conform with any applicable Australian Airworthiness Directives.

(2) An Airworthiness Approval Tag, FAA Form 8130-3, issued in accordance with the requirements of FAR 21, or other document specified in Air Navigation Orders Part 100* or otherwise specified or approved by the Department of Transport, will be accepted as evidence that the products conform with the type design and are either new or newly overhauled.

(3) Products need not incorporate modifications or manufacturers' service documents made mandatory by Australian Airworthiness Directives.

However, since it may be difficult to determine in Australia whether the product complies with the mandatory documents, information as to the modification status of a product would be of help to the Australian user.

A statement by the person issuing the airworthiness approval tag or alternative document will be accepted as evidence of the modification status of the products.

Page 22OCROpen in PDF

Appendix 2 SECTION 2 - SPECIAL REQUIREMENTS The following identifies those special administrative requirements which must be satisfied at the time of export, for a particular product to be eligible for Australian airworthiness acceptance or validation.

A. Aircraft, First of a Particular Type or Model

(1) An Export Certificate of Airworthiness may be issued when it has been demonstrated to the responsible region of the FAA that the aircraft complies with the requirements of the apropriate Section of Part 101 of Air Navigation Orders. Alteratively, such an Export Certificate of Airworthiness may be issued when it has been demonstrated to the Department of Transport that the aircraft complies with the appropriate Section of Part 101 of Air Navigation Orders and the Department of Transport has advised the responsible region of the FAA in writing of its acceptance of the aircraft.

The Section against which the aircraft has been demonstrated to comply should be endorsed in the Export Certificate of Airworthiness. The following guidance is offered:

(1) Export airworthiness approval of aircraft located outside the United States of America, its territories or possessions will be subject to the provisions of subparagraph (b)(2), Section 21.325, Part 21, of the Federal Aviation Regulations.

(ii) Compliance with the requirements of Air Navigation Orders may be demonstrated to an authorized officer or officers of the Australian Department of Transport. These officers will normally visit the United States to assess compliance only in the case of aeroplanes of maximum takeoff weight greater that 5700 kg (12,566 lbs.) or multi-engine rotorcraft.

(2) In some circumstances it may be impossible or undesirable to show that an aircraft complies with all the requirements of the appropriate Section of Part 10l of Air Navigation Orders until the aircraft arrives in Australia. Similarly it may be more appropriate that modification to achieve compliance with the Air Navigation Orders be deferred until the aircraft arrives in Australia. In these circumstances an Export Certificate of Airworthiness may be issued when it has been demonstrated to the responsible region of the FAA that the aircraft complies with much of the requirements of the appropriate Section of Part 101 of the Air Navigation Orders as are desired and the requirements not complied with are clearly established. The Export Certificate of Airworthiness will be endorsed with those exceptions and with the applicable Section of Air Navigation Orders Part 101 against which the demonstration has been made. The following guidance is offered:

(i) Circumstances in which it may not be possible to demonstrate compliance with the requirements before export include the following:

Page 23OCROpen in PDF

Appendix 2

(a) Those where interpretations or assessments have to be given by the Department of Transport and where an authorized officer is not available in the United States to perform these functions; and

(b) Those where demonstrations of radio communication/ navigation and other electronic equipment need to be given using Australian ground aids.

(11) There are some circumstances where compliance can only be demonstrated or modification can only be performed by the manufacturer in which cases the applicant should note the possibility of difficulties developing later, should he proceed without that compliance.

LETES of Airworthiness, if it has been issued for no longer than 90 days or 50 (111) In the circumstances concerned, the US Export Certificate operating hours, will be validated, if so requested, to permit the aircraft to be flown to Australia. An Australian Certificate of Airworthiness will be issued for the aircraft only when it has been demonstrated to the Department of Transport that the previously unfulfilled requirements have been complied with or agreement has been reached with the Australian applicant as to a program of compliance.

(3) In some cases it may not be possible, before export of an aircraft to Australia, to provide all the documents and data required, by the relevant Section of Part 101 of Air Navigation Orders. In these cases an Export Certificate of Airworthiness may be issued when as many of the documents and data as possible are supplied to the responsible region of the FAA and documents and data not supplied are clearly defined. The Export Certificate of Airworthiness will be endorsed with those exceptions and with the applicable Section of Air Navigation Orders, Part 101 againat which the supply of documents and data has been assessed. The following guidance is offered:

(1) The documents and data required by the Air Navigation Orders to be supplied to the Department of Transport, include data on each aircraft as well as on the aircraft type. These latter documents are only required when the aircraft is the first of its type to be imported into Australia.

chaser (on the basis of information furnished to the purchaser by the Australian Department of Transport), or from a representative of the Department of Transport, as to whether an aircraft is the first of its type or model to be imported into Australia.

(111) Practically all of the documents and data concerned can only be supplied by the manufacturer. An applicant should, therefore, note the possibility of difficulties developing later should he proceed without that material.

Page 24OCROpen in PDF

Appendix 2 In the circumstances concerned, the United States Export Certificate of Airworthiness may be validated, if so requested, to permit the aircraft to be flown to Australia. An Australian Certificate of Airworthiness will be issued for the aircraft only when the remaining agreement has been reached with the Australian applicant as to a program for supply of the material.

(4) Supplementary Type Certificates must be approved additionally by the Australian Department of Transport. Request for approval should be accompanied by such substantiating data as may have been required by or submitted to the Federal Aviation Administration.

B. Aircraft Not First of a Particular Type or Model

(1) An Export Certificate of Airworthiness may be issued either when it has been demonstrated to the responsible region of the FAA that the aircraft complies with the requirements of the appropriate Section of Part 101 of Air Navigation Orders, or when compliance with the appropriate section of Part 101 of Air Navigation Orders has not been demonstrated, provided the Export Certificate of Airworthiness is endorsed accordingly. The Section against which the aircraft has or has not been demonstrated to comply, as the case may

(2) The documents and data required by the Air Navigation Orders to be supplied to the Department of Transport need only appertain to the individual aircraft (not to the type or model). A copy of a Flight Manual is required to be submitted to the Department of Transport prior to the issue of an Australian Certificate of Airworthiness.

C. Aircraft Products and Components

(1) _ In the case of FAA Class I products - a United States of America, Federal Aviation Administration Form 8130-4 (Export Certificate of Airworthiness);

In the case of FAA Class II products - a United States of America, Federal Aviation Administration Form 8130-3 (Airworthiness Approval Tag);

(3) In the case of FAA Class III products -

(i) A United States of America, Federal Aviation Administration Form 8130-3 (Airworthiness Approval Tag); or

(ii) A document issued by the manufacturer of the component and which contains a certification to the effect that the component was manufactured under -

(a) A Production Certificate granted under United States of America, Federal Aviation Regulations Part 21, Subpart G;
