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-2005-133 affecting EADS SOCATA TBM 700 model aircraft. France is the State of Design for this model. CASA has assessed this AD and has issued Australian AD/TBM 700/43 which will become effective on 17 August 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 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 Australian Parliament, establishes the legal framework for the regulation of civil aviation in Australia, focusing on safety and efficiency. This Act empowers the Governor-General to make regulations that safeguard air navigation, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, made under the authority of the Act, allow CASA to issue these directives for particular kinds of aircraft or aeronautical products, ensuring that they meet safety standards. The issuance of these directives is a legislative instrument, subject to disallowance and review processes.
In the context of international civil aviation, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. When a State of Design issues an airworthiness directive, CASA must evaluate the information and, if necessary, issue an Australian airworthiness directive to enforce the requirements. This process is exemplified by the issuance of Australian AD/TBM 700/43 in response to the French DGAC's AD F-2005-133 for the EADS SOCATA TBM 700 model aircraft, reflecting Australia's adherence to international conventions and obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to the issuance of airworthiness directives (ADs) in the context of ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve as a mechanism for ensuring the continuing airworthiness of aircraft as per the requirements laid out in Annex 8 to the Convention on International Civil Aviation. Specifically, the State of Design holds the responsibility for the airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of an individual aircraft registered within its jurisdiction. In the case of Australian-registered aircraft, CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce these requirements. This process ensures that Australian aviation standards remain aligned with international obligations and safety protocols.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (39.001(1)). These ADs are intended to ensure the continued airworthiness of aircraft and are issued when there is a need to address safety issues or compliance with airworthiness standards. Subregulation 39.001(5) further clarifies that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and hence, it is a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. This means that while ADs have the force of law, they are subject to disallowance by Parliament if necessary.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and other relevant authorities are significant. Under Annex 8 to the Convention on International Civil Aviation, the State of Design—in this case, France for the EADS SOCATA TBM 700 model aircraft—has the overarching responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to the State of Registry to ensure the aircraft's airworthiness. In Australia, CASA, as the national airworthiness authority, is responsible for assessing any ADs issued by the State of Design and, if deemed appropriate, issuing corresponding Australian ADs. For example, following the issuance of AD F-2005-133 by the French DGAC, CASA issued Australian AD/TBM 700/43 to mandate the requirements for the TBM 700 model aircraft registered in Australia.
Failure to comply with the airworthiness directives can lead to severe consequences. If an aircraft operator fails to adhere to the requirements set out in an AD, they may be putting the safety of the aircraft and its occupants at risk. Under the Civil Aviation Act 1988, non-compliance with ADs can result in civil penalties, including fines and potential prosecution. The severity of the penalty can depend on the nature and extent of the non-compliance, but it is essential for aircraft operators to strictly follow the ADs to avoid any legal repercussions. Additionally, CASA has the authority to take enforcement actions, including grounding non-compliant aircraft, which can have significant operational and financial impacts on the operators.
The legislative framework surrounding airworthiness directives is designed to ensure that all stakeholders, including aircraft manufacturers, operators, and regulatory authorities, work collaboratively to maintain the highest safety standards. Given the international nature of aviation, harmonised standards and requirements are crucial. The regulations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust structure for the issuance and enforcement of ADs, thereby contributing to the overall safety of civil aviation.
