CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 US FAA has issued AD 2004-26-02 affecting General Electric CF 34 engines. US is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CF34/9, which will become effective on 17 March 2005.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, 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, ensuring the safety, efficiency, and orderly development of civil aviation. This legislation was introduced to address the need for comprehensive regulation in the aviation sector to safeguard public safety and to ensure compliance with international aviation standards. The Act is administered by the Civil Aviation Safety Authority (CASA), which is responsible for implementing the provisions of the Act through regulations such as the Civil Aviation Safety Regulations 1998. These regulations empower CASA to issue airworthiness directives (ADs) as a means to mandate safety requirements for aircraft registered in Australia. The policy objective of the Civil Aviation Act 1988 is to maintain high standards of safety and efficiency in civil aviation, aligning Australia's practices with international norms as set forth by the International Civil Aviation Organization (ICAO).
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are essential for ensuring the continuing airworthiness of aircraft and are issued by CASA in accordance with Australia’s obligations under the Convention on International Civil Aviation. This legislative framework applies to all aircraft registered in Australia, irrespective of their State of Design, and mandates CASA’s role as the national airworthiness authority. ADs are considered legislative instruments under the Legislative Instruments Act 2003 and are issued without public consultation, as determined by the Office of Regulatory Review, which also concluded that these directives do not require a Regulatory Impact Statement. CASA's authority to issue such directives is exercised in response to ADs issued by the relevant State of Design, ensuring alignment with international standards and obligations.
Key Provisions
The Civil Aviation Act 1988 (Act) and the Civil Aviation Safety Regulations 1998 (Regulations) establish the framework for issuing airworthiness directives (ADs), as seen in section 98 and regulation 39.001 respectively. Section 98 allows the Governor-General to make regulations for air navigation safety, while regulation 39.001 enables the Civil Aviation Safety Authority (CASA) to issue ADs for aircraft or aeronautical products. Importantly, subregulation 39.001(5) specifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and thus a legislative instrument according to the Legislative Instruments Act 2003.
The obligations imposed by these provisions are significant for both CASA and the State of Registry of an aircraft. CASA, as Australia’s national airworthiness authority, must assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. This is outlined in Annex 8 to the Convention on International Civil Aviation, which places responsibility for continuing airworthiness on the State of Design and mandates that they provide necessary information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. These obligations ensure that airworthiness directives issued by States of Design are appropriately considered and implemented within Australia.
Breaches of airworthiness directives can lead to serious consequences, both civil and criminal. Although the specific details of penalties for non-compliance are not exhaustively covered in the provided text, it is clear that non-compliance can result in significant legal repercussions. The Civil Aviation Act 1988 and associated regulations likely contain provisions for enforcement actions, which could include fines, imprisonment, or both, depending on the severity and frequency of the breach. Given the critical nature of airworthiness directives in ensuring the safety of air navigation, violations can also result in grounding of aircraft, which has direct implications for public safety and operational integrity.
The process of issuing ADs such as AD/CF34/9, in response to AD 2004-26-02 from the US Federal Aviation Administration (FAA), demonstrates the international cooperation required under the Convention on International Civil Aviation. The AD/CF34/9 will become effective on 17 March 2005, reflecting Australia's commitment to maintaining international safety standards. The AD was issued without public consultation due to its basis in international obligations and the determination by the Office of Regulatory Review that such directives do not require a Regulatory Impact Statement. This streamlined process ensures timely responses to safety concerns, minimising potential risks while adhering to regulatory standards.
