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 French DGAC has issued AD F-2004-123 R1 affecting A319, A320 and A321 model aircraft. France is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A320/160, Amendment 1, which will become effective on 1 September 2005. 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, enacted by the Australian Parliament, governs the regulation of civil aviation to ensure safety and efficiency. In line with this objective, the Civil Aviation Safety Regulations 1998 were established to provide detailed safety standards and procedures, including the issuance of airworthiness directives (ADs) under regulation 39.001. ADs are legislative instruments that mandate the requirements for the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), acting as Australia's national airworthiness authority, is responsible for issuing these ADs when necessary, such as in response to directives issued by the aircraft's State of Design, ensuring compliance with international standards and Australia's obligations under the Convention. This particular AD, issued by CASA in response to a French AD concerning A319, A320, and A321 model aircraft, was made without public consultation as it directly addresses international obligations and safety requirements.
Scope and Application
The Civil Aviation Act 1988, as amended, provides the legislative framework for civil aviation safety in Australia, with the Civil Aviation Safety Regulations 1998 detailing the mechanisms for ensuring the airworthiness of aircraft and aeronautical products. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments that become effective upon issuance, in accordance with the provisions of the Legislative Instruments Act 2003. The issuance of ADs is a critical mechanism for enforcing continuing airworthiness, aligning with obligations under the Convention on International Civil Aviation and the requirements set by the State of Design. In cases where an AD is issued by a foreign State of Design, such as the French DGAC's AD F-2004-123 R1 affecting A319, A320 and A321 model aircraft, CASA is mandated to review and, if necessary, issue a corresponding Australian AD to ensure compliance and safety within the Australian jurisdiction. This process is governed by the obligations under international conventions and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are sections 98 and 39.001 respectively. Section 98 allows the Governor-General to make regulations that are in the interests of the safety of air navigation. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. This regulation underscores CASA's role in ensuring that aviation safety standards are met, and that any necessary modifications or requirements are enforced to maintain the airworthiness of aircraft.
The Civil Aviation Safety Regulations 1998 impose specific obligations on CASA and other entities involved in civil aviation. For example, CASA is mandated to assess information provided by the State of Design and, if necessary, issue an Australian AD to ensure compliance with international standards. This includes taking into account ADs issued by other states, such as the French DGAC's AD F-2004-123 R1 affecting A319, A320, and A321 model aircraft. The State of Registry, which in the case of Australia is CASA, is responsible for ensuring that all aircraft registered in Australia meet continuing airworthiness requirements. This involves adopting or developing the necessary regulatory requirements to address any identified safety issues.
Any breaches of the regulations set forth in the Civil Aviation Safety Regulations 1998 can lead to serious civil and criminal consequences. Although specific offences and penalties are not detailed in the text, general aviation regulations often include provisions for hefty fines and potential imprisonment for individuals and corporations that fail to comply with ADs. Non-compliance with airworthiness directives can result in the grounding of aircraft, which not only poses safety risks but also has significant financial implications for airlines and other aviation stakeholders. The severity of the penalties underscores the importance of adhering to these regulations to maintain the high safety standards required in the aviation industry.
The ADs themselves are considered legislative instruments under the Legislative Instruments Act 2003. This means that they have the force of law and must be adhered to by all relevant parties. Given their legislative status, ADs are subject to disallowance procedures as outlined in the Acts Interpretation Act 1901. This legal framework ensures that the ADs are carefully scrutinised and that any potential issues can be addressed before they are implemented. The AD issued by CASA, such as AD/A320/160, Amendment 1, becomes effective on a specified date and replaces any previous directives, thereby ensuring that the most current safety requirements are being followed.
