AD/CJ610/7 – State of Design Airworthiness Directives

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. Under subsection 98 (5D) of the Act, a legislative instrument made under 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.

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. When a foreign State of Design issued an AD before 1 October 2009 for a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the foreign State of Design.

The United States of America Federal Aviation Administration (FAA) issued ADs 75‑19-05, 80-08-06R1, 85-18-03, 97‑25-08, 98-23-06 and 2001-10-12 affecting General Electric CJ610 series engines in 1975, 1981, 1985, 1997, 1998 and 2001 respectively. The United States of America is the State of Design for this engine series. As an aircraft fitted with this engine series has now been registered in Australia, and as the FAA ADs pre-date automatic acceptance of foreign ADs under Part 39 of CASR, CASA has issued AD/CJ610/7 to mandate the requirements of FAA ADs 75‑19-05, 80-08-06R1, 85-18-03, 97‑25-08, 98-23-06 and 2001-10-12.

Consultation

As AD/CJ610/7 is being made in accordance with CASA’s obligations under Annex 8 to the Convention on International Civil Aviation, 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 and the operator of the one affected aircraft currently on the Australian aircraft register should already be compliant with the AD. The requirements of the instrument apply to holders of certificates of registration of relevant aircraft.

Impact on categories of operations

The instrument is likely to have no effect on operations conducted by the relevant aircraft because the aircraft should already be compliant with the AD.

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 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 15 July 2022.

[Instrument number AD/CJ610/7]

Civil Aviation Safety Authority

Overview

The Civil Aviation Safety Regulations 1998, enacted to implement the Convention on International Civil Aviation, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). AD/CJ610/7, introduced under section 98 of the Civil Aviation Act 1988, mandates the requirements of pre-existing US Federal Aviation Administration (FAA) ADs for General Electric CJ610 series engines, given the registration of an aircraft fitted with this engine series in Australia. The policy objective is to ensure the continuing airworthiness of aircraft by adopting international safety standards, thereby safeguarding air navigation safety. This legislative instrument, made by a delegate of CASA, commenced on 15 July 2022 and aligns with human rights, as outlined in the Statement of Compatibility with Human Rights. The Civil Aviation Safety Regulations 1998 were introduced by the Australian Parliament to ensure that civil aviation operations within Australia meet international safety standards as outlined in the Convention on International Civil Aviation. AD/CJ610/7 was issued by CASA to address the need for compliance with pre-existing FAA ADs for General Electric CJ610 series engines, following the registration of an aircraft equipped with such engines in Australia. The directive is intended to maintain the safety of air navigation by ensuring that all relevant aircraft comply with the specified safety requirements. The instrument does not require a Regulation Impact Statement and is compatible with human rights, as it does not engage any of the applicable rights or freedoms.

Scope and Application

The AD/CJ610/7, an airworthiness directive issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Safety Regulations 1998, applies to aircraft registered in Australia that are fitted with General Electric CJ610 series engines. This directive mandates compliance with specific airworthiness directives previously issued by the Federal Aviation Administration (FAA) of the United States of America. These FAA directives, which pre-date the automatic acceptance of foreign ADs under Part 39 of the Civil Aviation Safety Regulations, concern the inspection and replacement of various engine components such as the accessory drive horizontal, turbine disks, turbine torque rings, combustion liner assemblies, and the removal of unapproved parts from service. As an Australian legislative instrument, AD/CJ610/7 extends to any aircraft registered in Australia that utilises the CJ610 series engines, regardless of the aircraft's origin or operator. The directive incorporates by reference the technical details from the FAA directives, ensuring that the requirements remain up to date with the FAA's evolving standards. Given that only one aircraft of this type is registered in Australia, the economic and cost impact of the directive is considered minimal, and it is anticipated that the aircraft operator will already be compliant with the mandated requirements. AD/CJ610/7 does not create any significant implications for human rights, as it does not engage any of the rights or freedoms recognised or declared in the international instruments listed in the Human Rights (Parliamentary Scrutiny) Act 2011.

Key Provisions

The main operative sections of the Civil Aviation Safety Regulations 1998, as amended by AD/CJ610/7, mandate the requirements of the Federal Aviation Administration (FAA) airworthiness directives (AD) for General Electric CJ610 series engines. These directives include AD 75-19-05, AD 80-08-06R1, AD 85-18-03, AD 97-25-08, AD 98-23-06, and AD 2001-10-12, which provide instructions for the inspection, replacement, and removal of specific engine components. The regulations are made under section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998, ensuring that the FAA ADs apply to aircraft registered in Australia. The directives are incorporated into Australian regulations by reference, meaning they are updated as they exist from time to time. The obligations imposed by AD/CJ610/7 primarily concern aircraft operators and owners of aircraft equipped with General Electric CJ610 series engines. Operators must ensure compliance with the FAA ADs by conducting necessary inspections, replacements, and removals of specified engine parts as outlined in the directives. This includes adhering to the technical instructions provided in the FAA ADs, which are accessible online. The Civil Aviation Safety Authority (CASA) is responsible for issuing and enforcing these requirements to maintain the continuing airworthiness of aircraft. Failure to comply with the requirements of AD/CJ610/7 may result in significant civil and criminal penalties. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to enforcement actions, including fines and potential criminal charges for individuals responsible for the aircraft. The maximum penalties for non-compliance can be severe, reflecting the critical nature of air safety regulations. CASA is empowered to take enforcement action against non-compliant aircraft, which can include grounding the aircraft until the necessary compliance measures are taken. CASA has determined that the economic and cost impact of AD/CJ610/7 is minimal, as the one affected aircraft currently registered in Australia should already be compliant with the FAA ADs. The directive is intended to ensure that the aircraft continues to meet safety standards, and it is not expected to impose significant additional costs or burdens on operators. The instrument has been carefully considered to align with the principles of best practice regulation, ensuring that the requirements are proportionate and justifiable.
