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/L200/5 affecting Morava L200 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/L200/5. The cancellation will become effective on
2 July 2009. 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to ensure the safety of air navigation, empowers the Governor-General to create regulations for the safety of air navigation, which includes the issuance of airworthiness directives. Pursuant to section 98 of this Act, the Civil Aviation Safety Regulations 1998 were established, with regulation 39.001 specifically authorising the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for types of aircraft or aeronautical products. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are critical for maintaining the continuing airworthiness of aircraft, a responsibility that lies with the State of Registry and the State of Design, as outlined in Annex 8 of the Convention on International Civil Aviation. The Act and its regulations thus provide a framework for ensuring that aircraft meet safety standards, with CASA acting on behalf of Australia to mandate these standards when necessary.
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) being the national airworthiness authority responsible for ensuring the continuing airworthiness of aircraft registered in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments that are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The State of Design, usually the country where the aircraft type is designed, is responsible for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry, including Australia. CASA must assess this information and, if necessary, issue Australian ADs to enforce the requirements of the State of Design. The issuance and cancellation of ADs are governed by Australia's obligations under the Convention on International Civil Aviation and do not typically require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 (the Act) and the Civil Aviation Safety Regulations 1998 (the Regulations) provide the framework for ensuring the safety and airworthiness of aircraft. Section 98 of the Act allows the Governor-General to make regulations for the purposes of the Act, particularly in the interests of the safety of air navigation. Regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments, as per subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901. Furthermore, under section 6 of the Legislative Instruments Act 2003, an AD is recognised as a legislative instrument.
The obligations and requirements imposed by these provisions are significant. The State of Design, which is the country where the aircraft type was designed, has the primary responsibility for ensuring the continuing airworthiness of the aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to the States of Registry, which are the countries where individual aircraft are registered. Australia, through CASA, must assess the ADs issued by the State of Design and, if necessary, issue its own ADs to ensure compliance with the safety requirements. In the case of AD/L200/5 affecting Morava L200 series aeroplanes, CASA assessed the AD and determined that the unsafe condition no longer existed, leading to the cancellation of the Australian AD.
There are no specific offences, penalties, or civil/criminal consequences outlined in the text for breaching the requirements of the ADs. However, failure to comply with an AD could potentially result in enforcement actions by CASA, which may include grounding the aircraft, imposing fines, or taking other regulatory actions to ensure compliance. While the maximum penalties are not detailed in the text, such breaches could have serious implications for aircraft operators and manufacturers, including safety risks and operational disruptions.
In conclusion, the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for maintaining the airworthiness of aircraft through the issuance of ADs. CASA plays a crucial role in ensuring that these directives are assessed and implemented in accordance with international standards, thereby safeguarding the safety of air navigation.
