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 2008-0131 affecting Airbus A330 series 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/A330/89, which will become effective on 25 July 2008.
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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, aiming to ensure the safety of air navigation and to meet Australia's obligations under international conventions. The Act empowers the Governor-General to make regulations that support the Act's objectives, including the issuance of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products to ensure their continuing airworthiness. The Civil Aviation Act 1988 thus addresses the need for a coherent regulatory framework to manage the complexities of air safety and operational standards in line with international agreements. The policy objective underpinning the Act is to maintain high safety standards in civil aviation, reflecting Australia's commitment to international safety protocols and practices.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, aiming to ensure the safety of air navigation. These directives are legally binding instruments that mandate corrective or preventative measures to maintain the airworthiness of aircraft registered in Australia. ADs are issued in response to identified safety issues and are typically aligned with international standards set forth by the International Civil Aviation Organization (ICAO). The application of these directives extends to all aircraft registered in Australia, regardless of whether they are operated domestically or internationally, thereby ensuring a uniform approach to airworthiness across the nation. ADs are not subject to disallowance by Australian Parliament but are subject to review and challenge through judicial means. The issuance of these directives is largely driven by the obligations of the State of Design under the Convention on International Civil Aviation and the State of Registry’s duty to ensure the continuing airworthiness of aircraft within its jurisdiction.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, enable the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act grants the Governor-General the authority to make regulations in the interests of safety, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft types or aeronautical products. This regulatory framework aligns with international obligations under Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type and must share necessary information with the State of Registry.
Under these regulations, CASA is tasked with assessing information provided by the State of Design and, when necessary, issuing corresponding ADs for aircraft registered in Australia. This was exemplified by CASA's assessment and subsequent issuance of Australian AD/A330/89 in response to EASA's AD 2008-0131, which concerns Airbus A330 series aircraft. This process ensures that Australian aircraft comply with international safety standards, as the State of Registry (Australia) must adopt or develop requirements to ensure the continuing airworthiness of aircraft within its jurisdiction.
The obligations imposed on parties governed by these provisions include the State of Design’s responsibility to provide continuing airworthiness information, and the State of Registry’s duty to assess and implement these directives. Operators and owners of affected aircraft must comply with the ADs issued by CASA, ensuring that any necessary maintenance or modifications are carried out to meet the safety standards outlined in the AD. Failure to comply with these directives can result in serious consequences, including potential grounding of the aircraft and enforcement actions by CASA.
The Civil Aviation Safety Regulations 1998 also outline the legal status of ADs, classifying them as disallowable instruments under section 46A of the Acts Interpretation Act 1901. This means that ADs can be subject to disallowance by Parliament. Furthermore, as per section 6 of the Legislative Instruments Act 2003, ADs are legislative instruments. Any breach of the ADs can lead to civil or criminal penalties. For instance, under section 30 of the Civil Aviation Act 1988, a person who contravenes a regulation can be fined up to 120 penalty units for an individual and 600 penalty units for a body corporate, in addition to potential imprisonment. These stringent measures underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
