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 Civil Aviation Safety Authority or its predecessors issued AD/BEECH 77/13 affecting Beechcraft 77 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 77/13. The cancellation will become effective on 3 July 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 ensure the safety of air navigation and to regulate the civil aviation industry in Australia. The Act provides the framework for the creation of regulations that govern various aspects of civil aviation, including the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products to maintain their airworthiness. This regulation aligns with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design is responsible for the continuing airworthiness of aircraft types and that States of Registry must ensure the ongoing airworthiness of individual aircraft registered within their jurisdictions. In the case of Australian registered aircraft, CASA acts on behalf of the State of Registry to issue such directives as necessary. The cancellation of a particular airworthiness directive affecting Beechcraft 77 model aircraft is a direct result of Australia’s commitment to international aviation safety standards, indicating that the unsafe condition identified in the original directive no longer exists.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These regulations mandate that CASA, as Australia’s national airworthiness authority, must ensure the continuing airworthiness of aircraft registered in Australia. When the State of Design, responsible for the continuing airworthiness of an aircraft type, issues an AD, CASA must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. For instance, CASA issued and subsequently cancelled Australian AD/BEECH 77/13 concerning Beechcraft 77 model aircraft, effective from 3 July 2008, as the unsafe condition no longer existed. This action aligns with Australia’s obligations under the Convention on International Civil Aviation and did not require consultation with the public or a Regulatory Impact Statement. The AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the Act.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, pertain to the issuance of airworthiness directives (ADs) under regulation 39.001 (paragraph 5). This regulation empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Importantly, ADs are recognised as legislative instruments under the Legislative Instruments Act 2003. This legal status means that ADs must adhere to the legislative process, ensuring that they are made and enforced in a manner consistent with other statutory requirements.
The obligations imposed by these provisions require the State of Design to take primary responsibility for the continuing airworthiness of an aircraft type, as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Design must provide essential information to the appropriate States of Registry to ensure that the aircraft maintain their airworthiness. In Australia, CASA, acting as the national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the required safety measures. This ensures that all aircraft registered in Australia comply with the continuing airworthiness standards set forth by international and domestic regulations.
Failure to comply with the ADs can lead to significant consequences. Firstly, under the Civil Aviation Act 1988, non-compliance with ADs can be considered an offence. Such breaches may result in civil or criminal penalties. While the specific penalties are not detailed in the text, it is known that non-compliance with safety regulations in aviation can lead to severe consequences, including fines, imprisonment, or both, depending on the severity of the breach and the jurisdictional provisions in place. Additionally, operational consequences may include grounding of the aircraft, suspension of flight operations, or revocation of airworthiness certificates, which can have substantial implications for aircraft operators and owners.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. The responsibilities are divided between the State of Design and the State of Registry, with CASA playing a crucial role in assessing and implementing these directives in Australia. Non-compliance with these directives can lead to significant civil and criminal penalties, underscoring the importance of adhering to these safety regulations.
