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 US FAA has issued AD 2008-10-03 affecting Bell 205 model helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 205/74, which will become effective on 21 May 2008.
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 was enacted to provide a comprehensive legislative framework for civil aviation in Australia, addressing various aspects related to the safety and regulation of air navigation. This Act empowers the Governor-General to create regulations for the Act's purposes, particularly focusing on the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the processes and requirements for maintaining airworthiness, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are legislative instruments that serve to ensure the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Act and accompanying regulations establish a clear framework for regulatory oversight and the maintenance of safety standards in Australian civil aviation.
The policy objective underpinning this legislation is to harmonise Australia's civil aviation safety practices with international standards, ensuring the safe operation of aircraft both domestically and in alignment with global conventions. By issuing airworthiness directives, CASA fulfills its role as the national airworthiness authority, enforcing necessary safety measures in response to directives issued by the aircraft's State of Design. This legislative approach underscores the importance of international cooperation in maintaining air safety, ensuring that Australian regulations and practices are consistent with global best practices.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation as mandated under section 98 of the Act. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. Such ADs, which are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, are legislative instruments as per section 6 of the Legislative Instruments Act 2003. This legislation applies to all aircraft registered in Australia, requiring the State of Registry to ensure the continuing airworthiness of these aircraft, in accordance with international standards set by the International Civil Aviation Organization (ICAO). The Act and its regulations extend to all entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers. There are no specific exclusions or thresholds mentioned within the scope of these regulations, though the issuance of ADs is guided by international conventions and obligations under the ICAO.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework within which airworthiness directives (ADs) are issued and managed in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to create regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. An AD, as outlined in subregulation 39.001(5), is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and, thus, a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations under this legislation primarily rest on CASA, which acts as Australia’s national airworthiness authority. When the State of Design issues an AD, CASA is required to assess the information and, if necessary, issue a corresponding Australian AD to enforce the requirements. This ensures that Australian aircraft meet international standards for airworthiness. In the case of the US Federal Aviation Administration’s (FAA) AD 2008-10-03 for Bell 205 model helicopters, CASA has assessed the directive and issued Australian AD/BELL 205/74, which will become effective on 21 May 2008. Given the international obligations under the Convention on International Civil Aviation, no public consultation was necessary for this AD, and the Office of Best Practice Regulation has determined that such directives do not require a Regulatory Impact Statement.
The issuing of an AD is carried out by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988. Failure to comply with the requirements set out in an AD can have significant consequences. The Civil Aviation Safety Regulations 1998 and related legislation may impose civil and criminal penalties for non-compliance. These penalties can include fines and imprisonment for serious breaches, reflecting the critical nature of air safety. The exact penalties depend on the severity of the breach and are determined according to the specific provisions of the relevant legislation. The overarching aim of these provisions is to ensure that all aircraft operating in Australian airspace meet the highest safety standards.
