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/3 affecting Pacific Aerospace Corporation 750XL aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/750XL/3, 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 - 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, enacted by the Commonwealth Parliament, addresses the need for regulations concerning the safety of air navigation in Australia. The Act provides the authority for the Governor-General to make regulations that are essential for maintaining the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. These ADs are crucial for ensuring that aircraft remain in a safe condition for operation, in line with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs are issued by CASA, Australia's national airworthiness authority, in response to directives from the aircraft's State of Design or as a result of Australia's obligations under international conventions. This legislative framework ensures that Australia's aviation safety regulations are consistent with global standards, thereby enhancing the safety of air navigation within Australian territory.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs) for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 provides that the Civil Aviation Safety Authority (CASA) may issue ADs for kinds of aircraft or aeronautical products, which are considered legislative instruments. The ADs are mandated by Australia’s obligations under the Convention on International Civil Aviation, particularly through Annex 8 which outlines the responsibilities of the State of Design and the State of Registry for ensuring the continuing airworthiness of aircraft. CASA must assess ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to comply with international obligations. The ADs do not require consultation with the Australian public or a Regulatory Impact Statement as they are issued in response to international directives. The ADs are issued by CASA under the authority of the Act and are intended to maintain the safety standards required under international aviation agreements.
Key Provisions
The Civil Aviation Act 1988, through section 98, grants the Governor-General the authority to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument, and by extension, a legislative instrument under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that ADs are officially recognised instruments designed to maintain the highest safety standards in civil aviation.
Under the obligations outlined in the Act and the Regulations, CASA must take several steps when an AD is issued by the State of Design, such as New Zealand in the case of the Pacific Aerospace Corporation 750XL aircraft. CASA is required to assess the information provided in the foreign AD and determine whether it is necessary to issue a corresponding Australian AD. This process is part of CASA’s responsibility to ensure the continuing airworthiness of aircraft registered in Australia. As per Annex 8 of the Convention on International Civil Aviation, CASA must align with the international obligations and standards set by the State of Design, ensuring that all necessary safety measures are implemented domestically.
Failure to comply with the ADs issued by CASA can result in significant legal consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict requirements on aircraft operators, manufacturers, and maintenance providers. Non-compliance with these directives can lead to enforcement actions, including the suspension or revocation of airworthiness certificates, fines, and potential criminal charges. The seriousness of these penalties underscores the importance of adhering to the ADs, which are designed to prevent accidents and maintain the safety of air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for issuing and enforcing airworthiness directives. CASA, as the national airworthiness authority, is tasked with assessing international ADs and issuing corresponding Australian ADs to ensure compliance with safety standards. The legal consequences for non-compliance are severe, highlighting the critical role of ADs in maintaining the safety and integrity of Australia’s civil aviation system.
