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/BELL 206/86 affecting Bell 206L and 206L-1 model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 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, Airframes in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation within the country. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety. Complementing the Civil Aviation Act 1988, the Civil Aviation Safety Regulations 1998 were enacted to further specify the regulatory requirements concerning aircraft and aeronautical products, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives, as legislative instruments, are critical in maintaining the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. CASA's responsibility includes assessing and, if necessary, issuing Australian ADs based on directives from the State of Design, ensuring that Australian-registered aircraft meet international safety standards.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. Specifically, under regulation 39.001, CASA has the authority to issue ADs for particular types of aircraft or aeronautical products, which are considered legislative instruments and can be disallowed under certain conditions. The Act applies to the State of Design, which holds the primary responsibility for the continuing airworthiness of aircraft types, and to the State of Registry, which must ensure the airworthiness of individual aircraft. When a State of Design issues an AD, CASA must assess this information and, if appropriate, issue an Australian AD. The geographic reach of these regulations is national, with CASA acting as Australia’s authority for airworthiness matters. This legislative framework is aligned with international standards set by the International Civil Aviation Organization under Annex 8 to the Convention on International Civil Aviation. The AD/BELL 206/86 concerning Bell 206L and 206L-1 model aircraft was issued and subsequently cancelled by CASA due to the resolution of the unsafe condition, effective from 23 October 2008. The cancellation of this AD was made in accordance with the requirements of the Civil Aviation Act 1988, without public consultation or the need for a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. In conjunction with this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that the continuing airworthiness of aircraft is managed effectively and consistently with international standards.
Under the obligations set out in the Act and Regulations, CASA must assess any airworthiness directives issued by the State of Design, particularly those that pertain to aircraft types registered in Australia. When an AD is issued by a State of Design, CASA is required to evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the requirements specified by the State of Design. This ensures that the continuing airworthiness of aircraft is maintained in line with international obligations and safety standards. The State of Registry, which is the country where the aircraft is registered, has the primary responsibility for ensuring that the aircraft remains airworthy, and must adopt or develop appropriate requirements to meet these standards.
The Act and Regulations also establish the consequences for non-compliance with airworthiness directives. While specific civil or criminal penalties are not detailed within the text provided, it is clear that failure to adhere to an AD could lead to significant safety risks. Such non-compliance might result in legal action, potentially including fines or other penalties as determined by relevant authorities. The seriousness of airworthiness issues necessitates stringent adherence to ADs, as they are crucial for maintaining the safety of air navigation and the integrity of aircraft operations.
In the particular case of AD/BELL 206/86, which was issued for Bell 206L and 206L-1 model aircraft, CASA has determined that the unsafe condition that originally prompted the AD has been resolved. Consequently, CASA has cancelled this AD, effective from 23 October 2008, and no replacement AD is required. This cancellation aligns with Australia's international obligations under the Convention on International Civil Aviation and has been executed without public consultation or the need for a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was made by the Manager, Airframes in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
