CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative 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 ICAO 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 State of Design issues an AD against 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 State of Design.
The European Aviation Safety Authority (EASA) has issued AD 2006-0069-E affecting Airbus A318, A319, A320 and A321 model aircraft. EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A320/172, Amendment 1, which will become effective on 4 April 2006. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, addressing the need for a coordinated approach to air safety, efficiency, and orderly development of air transport. The Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, and one of these regulatory mechanisms is the issuance of airworthiness directives (ADs). These directives, as outlined in the Civil Aviation Safety Regulations 1998, are legislative instruments that CASA can issue to maintain the airworthiness of aircraft and aeronautical products. The objective of these regulations is to harmonise with international standards set by the International Civil Aviation Organization (ICAO), ensuring that Australian aviation practices align with global safety norms. This legislative approach underscores the importance of international cooperation in maintaining air safety and reflects Australia's commitment to its obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, provides a comprehensive regulatory framework for ensuring the safety of civil aviation in Australia. The Act applies to all persons, entities, and industries involved in civil aviation activities within Australia, including aircraft operators, manufacturers, maintenance providers, and other stakeholders. The jurisdictional reach of this legislation extends across the Commonwealth, ensuring a uniform approach to air safety across the nation. The Act empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legally binding instruments designed to mandate specific safety measures for aircraft and aeronautical products. These ADs, which are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are issued to maintain the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). While the Act covers a broad scope, certain exclusions and exemptions may apply based on specific circumstances, such as when ADs are issued in direct response to international obligations, as was the case with AD/A320/172, Amendment 1, issued in response to an EASA directive. This AD, which cancels and replaces a previous issue, reflects Australia’s commitment to international safety standards and the responsibilities of the State of Registry in ensuring aircraft airworthiness.
Key Provisions
The Civil Aviation (Airworthiness) Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. An AD, as stated in subregulation 39.001(5), is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is considered a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These directives serve as a critical mechanism for maintaining the continuing airworthiness of aircraft types, a responsibility that lies with the State of Design as per Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, must evaluate and, when necessary, issue Australian ADs to enforce the requirements set forth by the State of Design.
The obligations imposed by these regulations are significant. The State of Design must ensure that it provides all necessary information to maintain the airworthiness of a specific aircraft type. Simultaneously, the State of Registry, which is responsible for the individual aircraft, must develop or adopt regulations to ensure the aircraft's continuing airworthiness. For instance, when the European Aviation Safety Authority (EASA) issued AD 2006-0069-E concerning Airbus A318, A319, A320, and A321 models, CASA assessed the directive and issued Australian AD/A320/172, Amendment 1, effective from 4 April 2006. This action exemplifies the procedural obligation CASA has under the Civil Aviation Act 1988 to align with international standards and ensure compliance with the continuing airworthiness of aircraft on the Australian Register.
Breaching the requirements set forth by these airworthiness directives can lead to serious consequences. Non-compliance with ADs may result in the aircraft being deemed unairworthy, potentially leading to severe civil and criminal penalties. While specific penalties are not detailed within the provided text, the overarching principle is that failure to adhere to the ADs could result in enforcement actions by CASA, including potential fines, legal proceedings, or the grounding of the aircraft. These measures underscore the critical nature of adhering to ADs to maintain safety standards in air navigation.
