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 2006-0174 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/A320/187, Amendment 1, which will become effective on 12 April 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 Acting Manager, Systems and New Technologies 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 legislative framework for the regulation of civil aviation in Australia, primarily focusing on ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General is empowered to create regulations that serve the interests of air navigation safety, including the issuance of airworthiness directives. Complementing the Act, the Civil Aviation Safety Regulations 1998 establish the procedures for such directives, allowing the Civil Aviation Safety Authority (CASA) to issue them for specific types of aircraft or aeronautical products. These directives are integral to maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry under international conventions such as Annex 8 to the Convention on International Civil Aviation. The issuance of an Australian airworthiness directive, such as AD/A320/187, Amendment 1, reflects CASA’s commitment to ensuring that Australian-registered aircraft meet international safety standards. This process is conducted in adherence to Australia’s obligations under international civil aviation agreements and is managed by CASA without public consultation, as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. The authority to issue such directives is granted under section 98 of the Civil Aviation Act 1988, enabling CASA to implement regulations in the interests of air navigation safety. These directives are considered legislative instruments as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these ADs is in line with Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to maintain the continuing airworthiness of aircraft types and to provide necessary information to States of Registry. The State of Registry, in this case CASA, must then ensure the ongoing airworthiness of individual aircraft on the Australian Register by issuing corresponding ADs when necessary. For example, following an AD issued by the European Aviation Safety Authority (EASA) for Airbus A318, A319, A320, and A321 models, CASA has issued Australian AD/A320/187, Amendment 1, effective from 12 April 2007. This process ensures that Australia meets its international obligations and maintains high safety standards in civil aviation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations, which includes the issuance of airworthiness directives (ADs) under regulation 39.001 of the Regulations. ADs are legislative instruments that pertain to specific types of aircraft or aeronautical products and are designed to address safety concerns. According to subregulation 39.001(5), ADs are disallowable instruments under the Acts Interpretation Act 1901, meaning they can be subject to disallowance by Parliament.
The obligations imposed by these regulations on parties and entities are primarily related to ensuring the continuing airworthiness of aircraft. The State of Design is responsible for providing necessary information to ensure the airworthiness of aircraft types, as per Annex 8 to the Convention on International Civil Aviation. The State of Registry must then develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. In Australia, the Civil Aviation Safety Authority (CASA) is the national airworthiness authority and is tasked with assessing ADs issued by States of Design and issuing corresponding Australian ADs where necessary. This ensures that all aircraft registered in Australia comply with the relevant safety standards.
Breaches of the requirements set out in airworthiness directives can lead to significant consequences. Non-compliance with ADs can result in serious safety risks, potentially leading to accidents or incidents. While specific offences, penalties, or civil/criminal consequences for breach are not detailed in the provided text, it is reasonable to infer that such non-compliance would be taken very seriously under the regulatory framework. The serious nature of air safety suggests that penalties could include fines, sanctions against operators, and potential legal action against individuals or entities that fail to adhere to the mandated airworthiness directives.
