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 2009-0076 Corrected affecting Airbus A330 model aircraft. The EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A330/101, which will become effective on 4 June 2009.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, 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, with a focus on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of air navigation safety. A significant aspect of these regulations is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which enables the Civil Aviation Safety Authority (CASA) to mandate specific safety requirements for certain types of aircraft or aeronautical products. The policy objective of these regulations is to maintain the highest standards of safety and airworthiness in Australian civil aviation, aligning with international obligations under the Convention on International Civil Aviation.
The issuance of an AD, such as the one concerning the Airbus A330 model aircraft by CASA following an AD issued by the European Aviation Safety Authority (EASA), underscores the importance of international cooperation and adherence to global standards in ensuring aircraft safety. Given the nature of these directives, which are based on assessments by the relevant State of Design and do not require public consultation or a Regulatory Impact Statement, CASA exercises its authority under section 84A(2) of the Act to implement necessary safety measures swiftly and efficiently.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, with the aim of ensuring the safety of air navigation as mandated by the Civil Aviation Act 1988. These ADs are legislative instruments that are subject to disallowance under the Acts Interpretation Act 1901 and are regulated by the Legislative Instruments Act 2003. The application of these directives is grounded in international obligations, particularly under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design with the primary responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, is obligated to evaluate ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure compliance with safety requirements. For instance, in response to EASA's AD 2009-0076 affecting Airbus A330 model aircraft, CASA issued AD/A330/101, which reflects Australia's commitment to international aviation safety standards. This process does not involve public consultation as it is governed by international conventions and is aimed at maintaining the highest safety standards within Australia’s airspace.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the ADs are significant. According to Annex 8 of the Convention on International Civil Aviation, the State of Design—the country where the aircraft type was designed—bears the primary responsibility for the continuing airworthiness of that aircraft type. This includes providing necessary information to ensure the aircraft's airworthiness to the appropriate States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When the State of Design issues an AD, such as the one issued by the European Aviation Safety Authority (EASA) for Airbus A330 model aircraft, CASA must assess the information and, if necessary, issue a corresponding Australian AD. This ensures that Australian operators of the affected aircraft types comply with the required safety standards.
The ADs carry significant consequences for non-compliance. Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, failure to comply with an AD can result in various civil and criminal penalties. Civil penalties may include fines, and in severe cases, criminal penalties may apply, such as imprisonment for individuals found in breach of the regulations. These penalties are intended to enforce adherence to the safety standards set forth by the ADs, ensuring the safety of air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for issuing airworthiness directives to maintain the safety of aircraft. The ADs, which are legislative instruments, impose specific obligations on States of Design and Registry to ensure aircraft airworthiness. Non-compliance with these directives can lead to civil and criminal penalties, emphasizing the importance of adherence to these regulations.
