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 Transport Canada has issued AD CF-2005-14R1 affecting Bombardier DHC-8-400 model aircraft. Canada is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DHC-8/101, Amendment 1, which will become effective on 3 August 2006. This AD cancels and replaces the previous issue.
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 Commonwealth Parliament, serves to regulate civil aviation in Australia and ensure the safety and efficiency of air navigation within the country. This Act empowers the Governor-General to create regulations that uphold the safety of air navigation, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA) to maintain the continuing airworthiness of aircraft types registered in Australia. In line with international obligations under the Convention on International Civil Aviation, particularly Annex 8, the State of Design is responsible for ensuring the airworthiness of aircraft types, while the State of Registry must enforce these requirements. CASA, acting on behalf of Australia, issues Australian airworthiness directives in response to directives from the State of Design, thereby ensuring compliance with international standards and maintaining the safety of aircraft operating in Australian airspace.
The Civil Aviation Safety Regulations 1998 further detail the regulatory framework under which CASA can issue these directives. Specifically, regulation 39.001 allows CASA to issue airworthiness directives for certain types of aircraft or aeronautical products, which are considered legislative instruments under the Acts Interpretation Act 1901. This particular AD/DHC-8/101, Amendment 1, issued by CASA, replaces the previous directive in response to AD CF-2005-14R1 from Transport Canada, and will become effective on 3 August 2006. Given that this AD arises from international obligations and has been assessed by CASA, no public consultation was required, and it was deemed unnecessary to prepare a Regulatory Impact Statement. The AD was issued by the Manager, New Technologies and Systems, on behalf of CASA, in accordance with the provisions of the Civil Aviation Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, enable the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), mandated by the Civil Aviation Act 1988. These directives apply to specific types of aircraft or aeronautical products to ensure the continuing safety and airworthiness of these aircraft within Australia. The authority to issue such directives stems from Australia's commitment to the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design the responsibility for maintaining an aircraft type's airworthiness. Consequently, CASA, as Australia's national airworthiness authority, is tasked with assessing foreign ADs issued by the State of Design and, if necessary, issuing corresponding Australian ADs. The geographic reach of these regulations is national, applying to all aircraft registered in Australia, and they do not require public consultation or a Regulatory Impact Statement. Any exclusions, exemptions, or thresholds are determined through subordinate instruments, which further define the application and enforcement of these ADs.
Key Provisions
The primary sections relevant to the issuance of airworthiness directives (ADs) under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include sections 98 and 39.001, respectively. Section 98 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. The ADs are legislative instruments as per the Legislative Instruments Act 2003. These ADs serve as a crucial means of ensuring the continuing airworthiness of aircraft types and are mandated under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other entities include the assessment and potential issuance of Australian ADs in response to ADs issued by the State of Design. For instance, CASA must review ADs from the State of Design, such as Transport Canada’s AD CF-2005-14R1 for Bombardier DHC-8-400 model aircraft, and issue corresponding Australian ADs, like AD/DHC-8/101, Amendment 1. The State of Registry, in this case, Australia, has the responsibility to ensure the continuing airworthiness of the aircraft registered within its territory, which necessitates the implementation of these ADs. Furthermore, the ADs must be issued in alignment with the obligations under international conventions and without the need for public consultation, as determined by the Office of Regulatory Review.
The issuance of ADs is governed by stringent regulatory frameworks and does not require public consultation due to their alignment with international civil aviation conventions. Additionally, these ADs are not subject to a Regulatory Impact Statement. The process of issuing an AD involves CASA’s Manager of New Technologies and Systems, who acts on behalf of CASA in accordance with subsection 84A(2) of the Civil Aviation Act 1988. Failure to comply with these ADs could lead to serious safety implications, although the specific civil or criminal penalties are not detailed in the text. The overarching goal is to ensure the safety and airworthiness of aircraft within Australia, in line with international standards and obligations.
