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 French DGAC has issued AD F-2005-189 affecting AIRBUS A320 model aircraft. France is the State of Design for these aircraft. CASA has assessed this AD and has issued Australian AD/A320/188, which will become effective on 19 January 2006.
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 Manager, New Technologies and Systems, 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, enacted by the Commonwealth Parliament, governs the regulation of civil aviation in Australia, with the primary aim of ensuring the safety and efficiency of air navigation. As part of its legislative framework, the Civil Aviation Safety Regulations 1998 were also enacted, providing a comprehensive set of rules and standards for aviation safety. One of the key mechanisms under this regulatory framework is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This process ensures that all aircraft and aeronautical products meet the necessary safety standards, thereby addressing the need for continuous oversight and management of airworthiness issues in compliance with international standards set by the International Civil Aviation Organization (ICAO). The ADs serve to bridge any safety gaps identified by the State of Design or State of Registry, ensuring that Australian aviation remains compliant with global aviation safety standards.
Scope and Application
The Civil Aviation Act 1988 applies to all aspects of civil aviation in Australia, including the regulation of aircraft, aeronautical products, and the safety of air navigation. The Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which provide the authority to issue airworthiness directives (ADs) to ensure the safety and airworthiness of aircraft. The ADs, which are legislative instruments, apply to the types of aircraft or aeronautical products specified in the regulations and are designed to address safety issues identified by the State of Design or State of Registry. The Act’s jurisdictional reach is national, with the Civil Aviation Safety Authority (CASA) serving as the national airworthiness authority responsible for assessing international ADs and issuing corresponding Australian ADs when necessary. This process is mandated by international obligations under the Convention on International Civil Aviation, and as such, consultation with the Australian public is not required for such ADs. The ADs are issued by CASA under the authority granted by the Act and are intended to ensure compliance with international standards and safety requirements.
Key Provisions
The Civil Aviation Act 1988 (section 98) allows the Governor-General to make regulations that are in the interest of air navigation safety. Pursuant to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority is crucial for ensuring the safety and airworthiness of aircraft operating in Australia. Subregulation 39.001(5) clarifies that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments. Additionally, the ADs must align with the obligations set forth in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type.
In practical terms, the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type to the States of Registry. The State of Registry, in turn, is responsible for the ongoing airworthiness of individual aircraft within its jurisdiction. When the State of Design issues an AD, such as AD F-2005-189 affecting AIRBUS A320 model aircraft, CASA evaluates this information and, if deemed necessary, issues an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian aircraft meet the safety standards set by the relevant international and national authorities.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to diligently assess any ADs issued by the State of Design. CASA must ensure that these directives are appropriately adopted and implemented in Australia to maintain the safety and airworthiness of aircraft registered in the country. The State of Registry is obligated to develop or adopt requirements that ensure the continuing airworthiness of aircraft under its jurisdiction. This includes complying with ADs issued by CASA in response to ADs from the State of Design.
Failure to comply with the requirements set out in an airworthiness directive can lead to significant consequences. While the specific offences, penalties, and consequences for breach are not detailed in the text, it is clear that non-compliance with ADs can result in severe civil and criminal penalties. The enforcement of these directives is critical to maintaining the high standards of safety required in the aviation industry. Adhering to ADs is not merely a regulatory obligation but a fundamental aspect of ensuring the safety of all individuals involved in air navigation.
