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 EASA has issued AD 2007-0023 affecting Airbus A330 model aircraft. EASA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A330/63, Amendment 1, which will become effective on 15 March 2007. 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, New Technologies and Systems, 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 legislative framework for the regulation of civil aviation in Australia, aiming to ensure the safety, efficiency, and orderly development of civil aviation. One of the key provisions of the Act is the authority it grants for the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which are legislative instruments. These directives serve to mandate safety requirements for specific types of aircraft and aeronautical products, aligning with the obligations Australia has under the Convention on International Civil Aviation. The ADs are issued by the Civil Aviation Safety Authority (CASA) following assessment of directives from the State of Design or in response to identified safety issues. The objective of these regulations is to maintain the continuing airworthiness of aircraft registered in Australia, ensuring compliance with international safety standards. The process for issuing ADs is designed to be efficient and responsive, reflecting the critical need for rapid implementation of safety measures without the requirement for public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988, as amended and complemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. These ADs are legislative instruments that apply to aircraft or aeronautical products, aimed at ensuring the safety of air navigation. The application of ADs is comprehensive, encompassing all aircraft registered within Australia and subject to the oversight of CASA. Notably, these regulations extend their reach internationally in alignment with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design holds overall responsibility for the continuing airworthiness of aircraft types, requiring them to furnish necessary information to the States of Registry. CASA, as Australia’s national airworthiness authority, must therefore evaluate such information and issue corresponding Australian ADs if deemed necessary. For instance, in response to the European Union Aviation Safety Agency (EASA) issuing AD 2007-0023 concerning Airbus A330 aircraft, CASA has issued Australian AD/A330/63, Amendment 1, effective from 15 March 2007, superseding the previous directive. This process does not involve public consultation or require a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) (sections 98 and 39.001 respectively). Section 98 allows the Governor-General to create regulations for the safety of air navigation, while regulation 39.001 enables the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments under the Acts Interpretation Act 1901 (subsection 39.001(5)).
The obligations imposed by these regulations are significant for the entities involved. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide all necessary information to ensure the aircraft’s airworthiness to the States of Registry (Annex 8 to the Convention on International Civil Aviation). The State of Registry, in turn, is tasked with ensuring the continuing airworthiness of individual aircraft, either by developing or adopting requirements to this effect (Annex 8). In Australia, CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements. This process ensures that all aircraft registered in Australia comply with internationally recognised airworthiness standards.
Failure to comply with the requirements of an AD can lead to serious consequences. Although specific offences and penalties are not detailed in the provided text, breaches of ADs typically result in civil or criminal penalties. In Australia, CASA can enforce these directives through various means, including fines and other regulatory actions, to ensure compliance. While the maximum penalties are not explicitly stated in the excerpt, non-compliance with ADs can result in severe repercussions, including potential grounding of the aircraft, which could have significant operational and safety implications.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a clear framework for issuing and enforcing ADs, ensuring the continuing airworthiness of aircraft in Australia. These regulations impose clear obligations on both the State of Design and the State of Registry to provide and enforce the necessary measures for maintaining airworthiness. Failure to comply with these directives can result in significant consequences, underscoring the importance of adherence to these safety standards.
