Explanatory Statement

Civil Aviation Safety Regulations 1998

AD/BEECH 55/79 Amdt 4 - Wing Bolt, Nut and Fitting

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 subsection 33 (3) of the Acts Interpretation Act 1901, where an Act confers a power to make, grant or issue any instrument of a legislative or administrative character (including rules, regulations or by-laws), the power shall be construed as including a power exercisable in the like manner and subject to the like conditions (if any) to repeal, rescind, revoke, amend, or vary any such instrument.

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 issued AD/BEECH 55/79 to correct an unsafe condition related to wing bolt nuts and fittings on Textron Aviation (formerly Beechcraft) 55, 58 and 95-55 series aircraft in 1996. The State of Design for these types, the United States of America Federal Aviation Administration (FAA), has not yet taken action to correct this unsafe condition. CASA subsequently issued AD/BEECH 55/79 Amdt 2 in 2002 to add an explanatory note to the Requirement section and add additional fittings to the parts requiring inspection and AD/BEECH 55/79 Amdt 3 in 2021 to not make provision for the use of an AMOC and retain the existing requirement for inspections to be carried out in accordance with the aircraft manufacturer’s instructions. AD/BEECH 55/79 Amdt 4 is issued to extend the compliance time for Requirement 1 of the AD by two months whilst a proposed airworthiness directive process is conducted for AD/BEECH 55/79 Amdt 5. This AD repeals and replaces the previous AD on this subject.

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.

Beechcraft Baron Shop Manual 55-590000-13 Revision E17 and Baron Maintenance Manual 102-590000-5 Revision A23, are incorporated by reference in the AD. For subsection 98 (5D) of the Act, the technical documents are incorporated as they exist on the date of commencement of this AD.

The technical documents incorporated into this AD, are not freely available, and are proprietary, copyright, fee-for-service documents, prepared on a commercial basis. They 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 documents available, in its Canberra or regional offices, by arrangement, and, in keeping with the proprietary nature of the documents, for viewing only, to any aircraft operator who is affected by the direction instrument, or to any interested person.

Consultation

This AD is being made at the request of industry, in particular an operator of the Beechcraft 55 series aircraft. As this AD amendment is of a minor or machinery nature and does not substantially alter existing arrangements apart from providing industry with additional time for compliance with Requirement 1 of the AD by two months whilst a proposed airworthiness directive process is conducted for AD/BEECH 55/79 Amdt 5, 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 the economic and cost impact of the instrument is not significant. The requirements of the instrument apply to holders of certificates of registration of relevant aircraft. The instrument will no cost impact for affected aircraft operators.

Impact on categories of operations

The instrument is likely to have a beneficial effect on operations conducted by the relevant aircraft because it extends the compliance period for aircraft operators.

Impact on regional and remote communities

The instrument will not have a negative impact on regional and remote communities and may reduce the maintenance costs of individuals and businesses operating Textron (Beechcraft) aircraft in those 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 instrument has been made by a delegate of CASA relying on the power of delegation under subregulation 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 10 May 2022.

Civil Aviation Safety Authority

Overview

The Civil Aviation Safety Regulations 1998, amended by AD/BEECH 55/79 Amdt 4, were enacted to address an unsafe condition concerning wing bolt nuts and fittings on Textron Aviation (formerly Beechcraft) 55, 58, and 95-55 series aircraft. This amendment was introduced by the Civil Aviation Safety Authority (CASA), following a request from industry. The objective of this legislative instrument is to extend the compliance period for aircraft operators by two months, allowing them additional time to comply with the airworthiness directive while CASA conducts a proposed process for AD/BEECH 55/79 Amdt 5. This amendment aims to ensure continued airworthiness and safety standards in the aviation sector, maintaining the overarching policy objective of prioritising the safety of air navigation.

Scope and Application

The Civil Aviation Safety Regulations 1998 Amendment Instrument AD/BEECH 55/79 Amdt 4 applies to holders of certificates of registration for Textron Aviation (formerly Beechcraft) 55, 58 and 95-55 series aircraft in Australia. This legislation is enacted under the authority of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, with the aim of ensuring the continuing airworthiness of these aircraft by correcting an unsafe condition related to wing bolt nuts and fittings. The instrument extends the compliance time for Requirement 1 of the AD by two months whilst a proposed airworthiness directive process is conducted for AD/BEECH 55/79 Amdt 5. This amendment is intended to provide additional time for aircraft operators to comply with the AD without any significant economic or cost impact, as determined by the Civil Aviation Safety Authority (CASA). The instrument does not apply to any particular person, a particular aircraft, or a particular aeronautical product, and is not subject to sunsetting provisions. The instrument incorporates by reference the Beechcraft Baron Shop Manual 55-590000-13 Revision E17 and Baron Maintenance Manual 102-590000-5 Revision A23, which are not freely available and are proprietary, copyright, fee-for-service documents. CASA will make the relevant sections of these technical documents available, by arrangement and for viewing only, to any aircraft operator who is affected by the direction instrument, or to any interested person. This legislative instrument is compatible with human rights, as it does not raise any human rights issues. Subordinate instruments may further extend or restrict the application of this legislation, and the Civil Aviation Safety Authority (CASA) may issue airworthiness directives for specific kinds of aircraft or aeronautical products under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The instrument also incorporates by reference 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. The instrument is intended to have an enduring operation, and therefore it would not be appropriate for it to be subject to sunsetting.

Key Provisions

Section 98 of the Civil Aviation Act 1988 (the Act) empowers the Governor-General to make regulations to implement provisions of the Convention on International Civil Aviation relating to safety, among other things. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 (CASR) enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (AD) for aircraft or aeronautical products. An AD is a legislative instrument unless it applies to a particular person, aircraft, or aeronautical product, as per sections 98(5B) and (5BA) of the Act. Subsection 98(5D) of the Act allows legislative instruments to apply, adopt, or incorporate matters from existing instruments or writings, even if those writings do not yet exist at the time of the instrument's creation. This provision allows the AD to incorporate technical documents, such as the Beechcraft Baron Shop Manual and Maintenance Manual, by reference. The AD imposes specific obligations on the parties it governs. Aircraft operators holding certificates of registration for Textron Aviation (formerly Beechcraft) 55, 58, and 95-55 series aircraft must ensure compliance with the requirements outlined in AD/BEECH 55/79 Amdt 4. This includes extending the compliance time for Requirement 1 of the AD by two months while CASA conducts a proposed airworthiness directive process for AD/BEECH 55/79 Amdt 5. The AD requires adherence to the aircraft manufacturer's instructions for inspections and maintenance of wing bolt nuts and fittings to correct an unsafe condition. CASA, as a current subscriber to the technical documents incorporated by reference, will make relevant sections available for viewing upon request by affected aircraft operators or interested parties, in line with the proprietary nature of these documents. Failure to comply with the AD may result in civil or criminal consequences. While specific penalties are not outlined in the AD, non-compliance with ADs generally could lead to enforcement actions by CASA, including fines, suspension or revocation of aircraft certificates, and potential criminal charges. The AD is intended to have enduring operation and is not subject to sunsetting provisions, as it is designed to correct an unsafe condition and ensure the continuing airworthiness of affected aircraft. CASA has determined that the economic and cost impact of the AD is not significant, as the requirements apply only to holders of certificates of registration for relevant aircraft and do not impose additional costs on affected operators. The AD is compatible with human rights as it does not engage any of the applicable rights or freedoms, as per the Statement of Compatibility with Human Rights. This compatibility ensures that the AD does not raise any human rights issues and aligns with the principles of best practice regulation of the Australian Government. The AD was made by a delegate of CASA, relying on the power of delegation under subregulation 11.260(1) of CASR and subsection 94(1) of the Act, and it commenced on 10 May 2022.
