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 issued AD CF-2005-10R2 affecting Bell 206 helicopters. Canada is the State of Design for these helicopters. As a result of a request from industry, CASA has amended the equivalent Australian AD to AD/BELL 206/158 Amendment 2 which will become effective on 25 October 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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to make regulations that are necessary for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 being a key set of regulations that establish the legal requirements for civil aviation safety. One such regulation is the issuance of airworthiness directives (ADs), which are legislative instruments used to mandate safety measures for specific types of aircraft or aeronautical products. The Civil Aviation Safety Authority (CASA), as Australia’s national airworthiness authority, issues these ADs to comply with international standards set by the International Civil Aviation Organization (ICAO) and to fulfill Australia's obligations under the Convention on International Civil Aviation. This legislative approach ensures that Australia maintains a robust framework for the continuing airworthiness of aircraft registered in the country.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations. These ADs are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve as a mechanism to maintain the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design has the overarching responsibility for the airworthiness of aircraft types, and the State of Registry must ensure the continuing airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, must respond to ADs issued by the State of Design and may issue corresponding Australian ADs to enforce these requirements on aircraft registered in Australia. The issuance of such ADs is made in accordance with the obligations under international conventions and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, establish the framework through which airworthiness directives (ADs) are issued. Under section 98 of the Act, the Governor-General is empowered to create regulations in the interest of air navigation safety, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
These ADs are critical in ensuring the continuing airworthiness of aircraft, a responsibility that ultimately lies with the State of Design as per Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to other States of Registry to maintain the airworthiness of the aircraft type. For an aircraft registered in Australia, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design. For instance, Transport Canada issued AD CF-2005-10R2 concerning Bell 206 helicopters, leading CASA to amend the corresponding Australian AD to AD/BELL 206/158 Amendment 2, effective from 25 October 2006.
Entities governed by these regulations, particularly CASA, are obligated to assess and, if necessary, issue ADs based on the information from the State of Design. This obligation ensures that all aircraft registered in Australia meet the required safety standards. Additionally, these obligations extend to ensuring compliance by aircraft operators and other stakeholders with the issued ADs, thus maintaining safety and regulatory standards across the aviation sector. Failure to comply with these ADs can lead to serious repercussions, including potential grounding of the aircraft or other enforcement actions by CASA.
In terms of penalties and consequences for breaches, the specific regulations do not detail maximum penalties within the provided text. However, the issuance of ADs and the failure to comply with them can result in civil or criminal penalties under broader aviation safety laws. Non-compliance might lead to fines, imprisonment, or other enforcement actions as prescribed by relevant legislation. The seriousness of these consequences underscores the importance of adhering to ADs to maintain the safety and integrity of air navigation.
