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 2008-0077 affecting Turbomeca ARRIEL series engines. EASA acts on behalf of France, the State of Design for this engine series. CASA has assessed this AD and has issued Australian AD/ARRIEL/29, which will become effective on 3 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 the safety of air navigation in Australia, ensuring compliance with international standards and fostering a safe and efficient aviation industry. This Act empowers the Governor-General to issue regulations that are critical for maintaining safety standards, and it delegates specific responsibilities to the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further detail the regulatory framework, including the issuance of airworthiness directives (ADs) as a means to mandate safety requirements for aircraft types and aeronautical products. ADs are legislative instruments that align with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which stipulates that the State of Design has a primary responsibility for ensuring the continuing airworthiness of aircraft. CASA, acting as Australia’s national airworthiness authority, must respond to ADs issued by the State of Design by issuing corresponding Australian ADs, where necessary, to ensure compliance with safety standards within the Australian Register. The AD process, as outlined, is intended to maintain the highest safety standards without the need for public consultation or a Regulatory Impact Statement, reflecting the international nature of the safety directives.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs concerning specific kinds of aircraft or aeronautical products. As stated in the Legislative Instruments Act 2003, ADs are considered legislative instruments, which means they carry the same legal authority as Acts of Parliament. The application of ADs is rooted in international obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the primary responsibility for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA as Australia’s national airworthiness authority, must ensure that any ADs issued by the State of Design are assessed and, if necessary, translated into Australian ADs. This process ensures compliance with international standards and obligations while maintaining the safety and airworthiness of aircraft registered in Australia. The issuance of ADs such as the Australian AD/ARRIEL/29, in response to EASA’s AD 2008-0077 concerning Turbomeca ARRIEL series engines, demonstrates the practical application of these regulations. Notably, due to the international nature of these directives and their technical basis, no public consultation or requirement for a Regulatory Impact Statement is mandated by the Office of Best Practice Regulation.
Key Provisions
The key operative sections of the Civil Aviation Safety Regulations 1998 include regulation 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulation is grounded in section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations to enhance the safety of air navigation. Additionally, subregulation 39.001(5) specifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they fall under the purview of the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA, as Australia's national airworthiness authority, to assess information provided by the State of Design and, if deemed necessary, issue corresponding Australian ADs to ensure the continuing airworthiness of aircraft registered in Australia. The State of Design, in this case France for the Turbomeca ARRIEL series engines, must provide information necessary for maintaining airworthiness. Meanwhile, the State of Registry, which for Australian aircraft is CASA, must implement the requirements stipulated in these ADs to ensure the ongoing safety of aircraft in their jurisdiction.
There are significant consequences for non-compliance with these ADs. Any breach of an AD can result in severe penalties, as the ADs are legally binding instruments. Although specific penalties are not detailed within the text, non-compliance with ADs can typically result in the grounding of affected aircraft, fines, and potentially criminal charges under the Civil Aviation Act 1988. Additionally, operators failing to adhere to ADs may face suspension or revocation of their aircraft's certificate of airworthiness, which is essential for legally operating the aircraft.
In summary, the ADs issued under these regulations are critical for maintaining the safety and airworthiness of aircraft within Australia. CASA's role in issuing and enforcing these directives ensures that aircraft meet the necessary safety standards as outlined by the State of Design and international aviation conventions. Failure to comply with these ADs can result in severe legal and financial repercussions for the aircraft operators.
