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.
Transport Canada has issued AD CF-2003-05R1 affecting Bombardier CL600-2B19 aircraft. Canada is the State of Design for these aircraft. CASA has assessed this AD and has issued Australian AD/CL-600/80, which will become effective on 30 August 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting 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 Commonwealth Parliament, establishes the framework for civil aviation regulation in Australia, focusing on ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to create regulations that support the objectives of the Act, specifically in maintaining the safety of air navigation. One significant regulation under this Act is the Civil Aviation Safety Regulations 1998, which among other provisions, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The authority to issue ADs is a critical tool in ensuring that aircraft meet continuing airworthiness standards, particularly in response to international obligations under the Convention on International Civil Aviation.
The issuance of ADs, such as the Australian AD/CL-600/80 in response to Transport Canada’s AD CF-2003-05R1, reflects Australia’s commitment to international standards and the collaborative approach to aviation safety. This process underscores the importance of adhering to directives issued by the State of Design and ensuring that these are appropriately implemented within Australia's regulatory framework. The legislative process for these directives, which are considered legislative instruments under the Legislative Instruments Act 2003, involves CASA’s assessment and subsequent issuance of an Australian AD, demonstrating a structured and internationally compliant approach to aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives, which are legislative instruments, are typically issued in response to safety issues identified by the State of Design and must be assessed and potentially mandated by CASA, Australia’s national airworthiness authority, for aircraft registered in Australia. Such directives are integral to maintaining the continuing airworthiness of aircraft as required under international conventions, such as Annex 8 to the Convention on International Civil Aviation, and thus are issued without public consultation or the need for a Regulatory Impact Statement. The ADs are implemented based on the obligations under international agreements and the directives issued by the relevant State of Design, ensuring that Australian aviation safety standards align with global safety protocols.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, grants the Governor-General the authority to create regulations that serve the Act's purpose and ensure the safety of air navigation. This is further operationalised through regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. The ADs are legally recognised as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003. These ADs are integral to maintaining the continuing airworthiness of aircraft, which is a responsibility of the State of Design under Annex 8 to the Convention on International Civil Aviation.
The obligations under the Civil Aviation Safety Regulations 1998 place the State of Design in a position of primary responsibility for ensuring the continuing airworthiness of an aircraft type. This involves providing necessary information to the appropriate States of Registry to maintain safety standards. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction. When a State of Design issues an AD, CASA, as Australia's national airworthiness authority, must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements stipulated by the State of Design. This ensures that Australian-registered aircraft comply with international safety standards.
The issuance of airworthiness directives is not without its legal implications. If any party fails to comply with the ADs issued by CASA, they may face civil or criminal consequences. While specific penalties are not detailed within the given text, it is understood that non-compliance could lead to enforcement actions by CASA. The Civil Aviation Safety Regulations 1998 do not require consultation with the Australian public for ADs issued in response to international obligations, as these are generally pre-determined by international conventions and agreements. Moreover, the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement, streamlining the process of issuing these directives to swiftly address safety concerns.
The ADs are crafted by authorised personnel within CASA, such as the Acting Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, in accordance with subsection 84A(2) of the Act. This structure ensures that ADs are issued with the necessary expertise and authority, maintaining the integrity and safety of air navigation in Australia. The process of issuing and enforcing ADs is thus a well-defined and legally backed mechanism to uphold aviation safety standards in alignment with international obligations.
