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 New Zealand CAA has issued AD DCA/750XL/5 affecting Pacific Aerospace 750 XL model aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/750XL/5, which will become effective on 7 July 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 - Airframes, 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 for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation and related activities. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. One such regulation, regulation 39.001 of the Civil Aviation Safety Regulations 1998, enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These directives are legislative instruments and play a crucial role in maintaining the continuing airworthiness of aircraft, in line with international obligations under the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, issues these directives to mandate specific requirements when necessary, often in response to directives issued by the State of Design or due to international obligations. This process ensures that Australian aviation standards are consistent with international practices, safeguarding the safety of air navigation.
Scope and Application
The Civil Aviation Regulations 1998, specifically under regulation 39.001, provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) in relation to certain kinds of aircraft or aeronautical products. This regulation is grounded in section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations for the safety of air navigation. The application of this Act and its regulations extends to all aircraft registered in Australia, as well as to any aeronautical products manufactured or maintained within Australia or imported into the country. The ADs issued under this regulatory framework are legislative instruments as per the Legislative Instruments Act 2003 and must comply with the requirements set out in Annex 8 to the Convention on International Civil Aviation, which pertains to the continuing airworthiness of aircraft. CASA, as Australia's national airworthiness authority, is obligated to assess ADs issued by the State of Design and, where necessary, issue corresponding Australian ADs to ensure compliance with international standards and the safety of air navigation.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act allows the Governor-General to make regulations, and regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This legislative framework is designed to maintain high safety standards in air navigation and ensure the continuing airworthiness of aircraft. An AD is a legislative instrument under section 46A of the Acts Interpretation Act 1901 and is considered a disallowable instrument. This means that while ADs are legally binding, they can be reviewed and potentially disallowed by Parliament.
The obligations imposed by the Act and regulations on parties and entities include ensuring that the State of Design provides necessary information for continuing airworthiness, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case New Zealand, must issue ADs to maintain the airworthiness of the aircraft type. CASA, as Australia’s national airworthiness authority, has the responsibility to assess any ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to mandate these requirements. For example, CASA has issued Australian AD/750XL/5 in response to the New Zealand AD DCA/750XL/5 affecting the Pacific Aerospace 750 XL model aircraft. This process ensures that Australian-registered aircraft meet international safety standards.
There are specific obligations for the State of Registry, which in this context is Australia. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft on its register. This includes implementing any ADs issued by the State of Design and ensuring compliance by operators of affected aircraft. CASA’s role is crucial in this regard, as it must evaluate the necessity of issuing Australian ADs and communicate these requirements effectively to relevant stakeholders. The AD/750XL/5 is an example of this process in action, where CASA has taken the necessary steps to align Australian regulations with international standards.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 also establish the consequences for non-compliance with ADs. Failure to comply with an AD can result in severe penalties, including fines and potential criminal charges. The specific penalties depend on the severity of the non-compliance and the potential risk posed to air safety. CASA has the authority to enforce these regulations and can take action against individuals or entities that fail to adhere to the mandated airworthiness requirements. This enforcement mechanism is vital in maintaining the high safety standards required in air navigation and ensuring the continuing airworthiness of aircraft in Australia.
