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 German LBA has issued AD 1998-343-3 affecting Dornier 328 model aircraft. Germany is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DO 328/62, which will become effective on 8 June 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 was enacted to provide for the regulation of civil aviation in Australia and to ensure the safety of air navigation, amongst other objectives. Under this Act, the Civil Aviation Safety Regulations 1998 were also created to further detail and implement the provisions of the Act, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations necessary for the purposes of the Act, specifically in the interests of air navigation safety. The policy objective of the Civil Aviation Act 1988, as demonstrated in the issuance of ADs, is to ensure the continuing airworthiness of aircraft in accordance with international standards and to meet Australia's obligations under the Convention on International Civil Aviation. This legislative framework allows CASA to issue ADs in response to directives issued by the State of Design, ensuring that Australian aircraft meet the necessary safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations apply to all aircraft and aeronautical products within Australia, and their primary objective is to ensure the continuing airworthiness of aircraft as mandated by the Convention on International Civil Aviation. CASA, as the national airworthiness authority, has the responsibility to assess airworthiness directives issued by the State of Design and, where appropriate, issue corresponding Australian ADs to enforce these requirements. The process for issuing such directives is streamlined and does not involve public consultation, as it is governed by international obligations and the need for immediate compliance with safety standards. ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The geographic reach of these regulations is national, ensuring that all aircraft registered in Australia comply with the continuing airworthiness standards set forth by international and domestic regulations.
Key Provisions
The Civil Aviation Act 1988 provides the foundational framework for the regulation of civil aviation in Australia, with specific reference to airworthiness directives under section 98. The Civil Aviation Safety Regulations 1998 further elaborate on this by detailing the process for issuing airworthiness directives (ADs) under regulation 39.001. According to subregulation 39.001(5), these ADs are considered disallowable instruments, thereby classifying them as legislative instruments in line with section 6 of the Legislative Instruments Act 2003. These directives are crucial as they mandate specific actions or conditions to ensure the continuing airworthiness of aircraft types, in compliance with Annex 8 to the Convention on International Civil Aviation.
The obligations under these regulations primarily fall on the Civil Aviation Safety Authority (CASA), which must assess and potentially issue Australian ADs in response to ADs from States of Design. For instance, when the German Luftfahrt-Bundesamt (LBA) issued AD 1998-343-3 concerning Dornier 328 model aircraft, CASA assessed the directive and issued the corresponding Australian AD/DO 328/62. This process underscores CASA’s role in ensuring that Australian-registered aircraft meet international safety standards. The State of Registry, in this case, Australia, is obligated to implement and enforce these ADs to maintain the airworthiness of the aircraft on its register.
Under the Civil Aviation Act 1988 and the associated regulations, failure to comply with airworthiness directives can lead to significant consequences. The Act does not explicitly outline specific offences, penalties, or civil/criminal consequences for non-compliance with ADs. However, non-compliance can lead to serious safety risks, and CASA has the authority to enforce compliance through various means, including grounding aircraft that do not meet the required standards. Although specific maximum penalties are not detailed within the explanatory statement, the overarching intent is to ensure that all stakeholders adhere strictly to the ADs to prevent potential hazards to flight safety.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for the issuance and enforcement of airworthiness directives, ensuring that Australian-registered aircraft meet international safety standards. CASA’s role in assessing and issuing these directives is pivotal, and compliance is mandatory to maintain the safety and airworthiness of aircraft operating within Australia. Non-compliance with these directives can result in significant safety risks and enforcement actions by CASA.
