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 European Aviation Safety Authority (EASA) has issued AD 2007-0106-E affecting ATR 42 model aircraft. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ATR 42/21, which will become effective on 25 October 2007.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, is designed to ensure the safety and efficiency of civil aviation in Australia. This legislation empowers the Governor-General to make regulations, including the Civil Aviation Safety Regulations 1998, which govern airworthiness and safety. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and oversight as per the Legislative Instruments Act 2003. The overarching objective of these provisions is to align Australian regulations with international standards, ensuring the continuing airworthiness of aircraft as mandated by the Convention on International Civil Aviation. CASA's role is to evaluate and, where necessary, issue Australian ADs in response to directives from the State of Design, such as the recent AD/ATR 42/21 issued in alignment with EASA's AD 2007-0106-E. This process reflects Australia's commitment to international safety standards and the efficient administration of civil aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific types of aircraft or aeronautical products, in line with the regulatory requirements for ensuring the safety of air navigation. This regulatory process is grounded in international conventions, specifically Annex 8 to the Convention on International Civil Aviation, which allocates responsibility for the continuing airworthiness of aircraft types to the State of Design and mandates that the State of Registry implement necessary measures to ensure compliance with airworthiness standards. Consequently, when a State of Design issues an AD, such as the European Aviation Safety Authority’s AD 2007-0106-E for ATR 42 model aircraft, CASA assesses the information and, if appropriate, issues a corresponding Australian AD, such as AD/ATR 42/21. These directives apply to all entities and persons involved in the operation and maintenance of the specified aircraft within Australia, ensuring adherence to nationally mandated safety standards. The jurisdictional reach of these regulations is national, extending uniformly across all states and territories of Australia, with no exclusions or exemptions specified in the given text. The issuance of ADs under these regulations is an integral part of maintaining aviation safety in accordance with both national legislation and international obligations.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish a framework for ensuring the safety of air navigation in Australia. Section 98 of the Act empowers the Governor-General to make regulations in the interest of air navigation safety, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs serve as critical tools for maintaining the continuing airworthiness of aircraft and are regarded as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Under these legislative provisions, CASA is tasked with the responsibility of assessing airworthiness directives issued by the State of Design—the country responsible for the design of the aircraft type—and issuing corresponding Australian ADs when necessary. This ensures that all aircraft registered in Australia comply with internationally recognised safety standards. The State of Registry, which is Australia in this context, must then implement these ADs to ensure the continuing airworthiness of the individual aircraft. This collaborative approach aligns with the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of both the State of Design and the State of Registry.
The obligations imposed on parties governed by these regulations are significant. CASA must rigorously assess any ADs issued by the State of Design and decide whether an Australian AD is necessary. If an AD is warranted, CASA must issue it, providing clear and specific directives to ensure compliance. The State of Registry, through CASA, must then ensure these directives are implemented by aircraft operators, thereby maintaining the airworthiness of all aircraft registered in Australia. Failure to comply with an AD can result in serious safety risks, and therefore, these obligations are paramount to public safety.
In terms of consequences for non-compliance, the Civil Aviation Act 1988 and associated regulations do not specify particular offences or penalties for failing to adhere to an airworthiness directive. However, non-compliance can lead to severe civil and criminal consequences, including fines and imprisonment, as per other provisions of the Act. The seriousness of these potential penalties underscores the critical importance of adhering to airworthiness directives. Ensuring compliance is not only a legal obligation but also a matter of public safety, given the high stakes involved in aviation safety.
