Explanatory Statement

Civil Aviation Safety Regulations 1998

AD/YA-1/6 – Pilot’s Safety Harness Attachment - Modification

Legislation

Under section 98 of the Civil Aviation Act 1988 (the Act), the Governor-General may make regulations for the purpose of carrying out and giving effect to the provisions of the Convention on International Civil Aviation relating to safety, amongst other things. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998 (CASR), the Civil Aviation Safety Authority (CASA) may issue an airworthiness directive (AD) for a kind of aircraft or aeronautical product. Under subsections 98 (5B) and (5BA) of the Act, an AD is a legislative instrument unless it is expressed to apply in relation to a particular person, a particular aircraft or a particular aeronautical product.

Subsection 98 (5D) of the Act provides that a legislative instrument made under the Act or the regulations may apply, adopt or incorporate any matter contained in any instrument or other writing as in force or existing from time to time, even if the other instrument or writing does not yet exist when the legislative instrument is made.

Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most International Civil Aviation Organization Contracting States.

The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft.

CASA has issued AD/YA-1/6 to reinstate a requirement for the modification of the pilot’s safety harness attachment on Yeoman Aircraft YA-1 250R series aircraft.

As Australia is the State of Design for the type, CASA is required to develop, and to transmit to other States of Registry, an AD to correct the problem. The AD requires a one-time modification of the pilot’s safety harness attachment.

Documents Incorporated by Reference

Under subsection 14 (2) of the Legislation Act 2003 (the LA), unless the contrary intention appears, a legislative instrument may not incorporate any matter contained in an instrument or other writing as existing from time to time. Subsection 98 (5D) of the Act provides that, despite section 14 of the LA, a legislative instrument made under the Act or the regulations may apply, adopt or incorporate any matter contained in any instrument or other writing as in force or existing from time to time.

Yeoman Aircraft Service Bulletin (SB) YA1-SB-006 dated 16 December 1964 provides instructions for the modification of the pilot’s safety harness attachment on Yeoman Aircraft YA-1 250 and YA-1 250R series aircraft. For subsection 98 (5D) of the Act, the technical document is incorporated as in force on the commencement date of this AD. The technical document is not freely available.

The technical document incorporated into this AD, which is not freely available, is a proprietary, copyright, fee-for-service document, prepared on a commercial basis. It can be purchased from the aircraft or component manufacturer by subscription.

As a matter of practicality, it would not be possible for aircraft operators to operate aircraft in Australian and foreign airspace without having their own subscription access to relevant technical documents of the aircraft or engine manufacturer. Nevertheless, as a current subscriber for the documents, CASA will make the relevant sections of the incorporated technical document available, in its Canberra or regional offices, by arrangement, and, in keeping with the proprietary nature of the document, for viewing only, to any aircraft operator who is affected by the instrument, or to any interested person.

Consultation

This AD is being re-made because the previously made AD on this subject lapsed with the introduction of the Legislative Instruments Act. As the re-making simply reinstates an AD previously made, with which aircraft should already be compliant, it is CASA’s view that it was not necessary or appropriate to undertake any further consultation under section 17 of the Legislation Act 2003.

Sector risk, economic and cost impact

Subsection 9A (1) of the Act states that, in exercising its powers and performing its functions, CASA must regard the safety of air navigation as the most important consideration. Subsection 9A (3) of the Act states that, subject to subsection (1), in developing and promulgating aviation safety standards under paragraph 9 (1) (c), CASA must:

(a) consider the economic and cost impact on individuals, businesses and the community of the standards; and

(b) take into account the differing risks associated with different industry sectors.

The cost impact of a standard refers to the direct cost (in the sense of price or expense) which a standard would cause individuals, businesses and the community to incur. The economic impact of a standard refers to the impact a standard would have on the production, distribution and use of wealth across the economy, at the level of the individual, relevant businesses in the aviation sector, and the community more broadly. The economic impact of a standard could also include the general financial impact of that standard on different industry sectors.

The economic and cost impact of the instrument has been determined by:

(a) the identification of individuals and businesses affected by the instrument;

(b) consideration of how the requirements to be imposed on individuals and businesses under the instrument will be different compared to existing requirements;

(c) a valuation of the impact, in terms of direct costs on individuals and businesses affected by the instrument to comply with the different requirements. This valuation is consistent with the principles of best practice regulation of the Australian Government.

CASA has assessed that there is no increase in economic or cost impact of the instrument. This AD is being re-made because the previously made AD on this subject lapsed with the introduction of the Legislative Instruments Act. The requirements of the instrument apply to holders of certificates of registration of relevant aircraft. The instrument will have zero net cost effect to operators over the previous instrument.

Impact on categories of operations

The instrument is likely to have no effect on operations conducted by the relevant aircraft because it will introduce no additional maintenance burden on aircraft owners over the previous instrument.

Impact on regional and remote communities

The instrument will not have a negative impact on regional and remote communities.

Regulation Impact Statement

A Regulation Impact Statement (RIS) is not required because ADs are covered by a standing agreement between CASA and the Office of Best Practice Regulation under which a RIS is not required for ADs (OBPR id. 14507).

Statement of Compatibility with Human Rights

A Statement of Compatibility with Human Rights is at Attachment 1.

Making and commencement

The AD has been made by a delegate of CASA relying on the power of delegation under sub regulation 11.260 (1) of CASR and subsection 94 (1) of the Act.

As an instrument relating to aviation safety made under CASR, Part 4 of Chapter 3 of the Legislation Act 2003 (sunsetting of legislative instruments) does not apply to this instrument (item 15 of the table in section 12 of the Legislation (Exemptions and Other Matters) Regulation 2015). The instrument requires that the action set out in the instrument, that relates to aircraft or aeronautical products, be taken to correct an unsafe condition. As such, the instrument is intended to have enduring operation and it would not be appropriate for it to be subject to sunsetting.

The instrument commences on 29 April 2022.

[Instrument number AD/YA-1/6]

Attachment 1

Statement of Compatibility with Human Rights

Prepared in accordance with Part 3 of the
Human Rights (Parliamentary Scrutiny) Act 2011

AD/YA-1/6 – Pilot’s Safety Harness Attachment - Modification

This legislative instrument is compatible with the human rights and freedoms recognised or declared in the international instruments listed in section 3 of the Human Rights (Parliamentary Scrutiny) Act 2011.

Overview of the legislative instrument

The legislative instrument is an airworthiness directive (AD). AD/YA-1/6 has been issued to reinstate a requirement for the modification of the pilot’s safety harness attachment on Yeoman Aircraft YA-1 250R series aircraft.

As Australia is the State of Design for the type, the Civil Aviation Safety Authority (CASA) is required to develop, and to transmit to other States of Registry, an AD to correct the problem. The AD sets out a required one-time remedial action to modify the pilot’s safety harness attachment.

Human rights implications

This legislative instrument does not engage any of the applicable rights or freedoms.

Conclusion

This legislative instrument is compatible with human rights as it does not raise any human rights issues.
