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 United States FAA has issued AD 2008-11-01 affecting Boeing 767 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B767/242, which will become effective on 3 July 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, Systems and New Technologies 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 legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of air navigation safety. Specifically, under section 98, the Civil Aviation Safety Regulations 1998 were developed to further delineate these regulations, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments that mandate compliance with specific airworthiness requirements for aircraft types and aeronautical products, reflecting Australia's commitment to international aviation safety standards as outlined in Annex 8 of the Convention on International Civil Aviation. The process involves CASA issuing ADs based on assessments of information provided by the State of Design, ensuring that Australian-registered aircraft meet continuing airworthiness standards.
The policy objective behind these regulations is to maintain the highest safety standards in civil aviation, in alignment with international obligations and best practices. This approach ensures that Australian aviation authorities can effectively respond to safety concerns and maintain the airworthiness of aircraft registered in Australia, thereby protecting passengers, crew, and the public. The ADs are issued under the authority of CASA, in accordance with the legislative framework provided by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, without the need for public consultation due to their international regulatory nature.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) empowered to mandate such directives under specific regulations. The application of these directives is pertinent to all aircraft and aeronautical products registered in Australia, encompassing both commercial and private entities within the aviation industry. The scope extends nationally, ensuring that all aircraft registered in Australia must comply with ADs issued by CASA. These regulations are not subject to exclusions or exemptions but are triggered by international obligations under the Convention on International Civil Aviation, specifically under Annex 8, which mandates that the State of Design and the State of Registry collaborate to maintain the continuing airworthiness of aircraft. In cases where the State of Design issues an AD, CASA must issue a corresponding Australian AD, as demonstrated by the issuance of AD/B767/242 in response to the United States Federal Aviation Administration’s AD 2008-11-01 for Boeing 767 series aircraft. The application of these regulations is further extended through subordinate instruments, which are legislative instruments themselves under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft. Specifically, section 98 of the Act empowers the Governor-General to make regulations, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and review under the Legislative Instruments Act 2003 and the Acts Interpretation Act 1901, respectively.
Under the Civil Aviation Safety Regulations 1998, CASA is mandated to issue airworthiness directives when the State of Design issues such directives for aircraft types registered in Australia. This process is governed by Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design bears the overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure this airworthiness. The State of Registry, in this case CASA, must then assess this information and issue corresponding Australian ADs as required. For example, following the issuance of United States Federal Aviation Administration (FAA) AD 2008-11-01 for Boeing 767 series aircraft, CASA issued Australian AD/B767/242, effective from 3 July 2008.
The obligations imposed by these regulations primarily fall on CASA, which must ensure the continuing airworthiness of aircraft registered in Australia. CASA must assess and implement ADs issued by the State of Design, ensuring that any necessary actions are mandated and enforced. This includes monitoring and ensuring compliance with ADs, which may involve inspections, maintenance requirements, or modifications to aircraft. Furthermore, CASA must communicate these requirements clearly to aircraft operators and ensure they understand and comply with the directives.
Failure to comply with airworthiness directives can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines. The maximum penalty for contravening an airworthiness directive is significant, reflecting the critical importance of adhering to safety standards. Additionally, non-compliance can result in criminal charges, with potential imprisonment for individuals or fines for corporations, further emphasising the seriousness with which these regulations are treated. CASA has the authority to take enforcement actions, including grounding non-compliant aircraft, to ensure that safety standards are upheld.
