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 206/67 affecting Bell 206 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, Systems and New Technologies 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 provide a comprehensive framework for the regulation of civil aviation in Australia, establishes the legislative foundation for ensuring the safety and efficiency of civil aviation operations. The Act empowers the Governor-General to issue regulations, including those pertaining to airworthiness directives (ADs), under section 98, thereby addressing gaps in aviation safety management by providing clear guidelines and mandates. Complementing this, the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft types or aeronautical products, ensuring that these regulations align with international standards set forth in Annex 8 of the Convention on International Civil Aviation. The policy objective of these regulations is to maintain the highest standards of airworthiness, reflecting Australia's commitment to international civil aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations in the interests of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and regulation under the Legislative Instruments Act 2003. The ADs are essential for maintaining the continuing airworthiness of aircraft and are issued in compliance with international standards set by the International Civil Aviation Organization (ICAO). The State of Design is responsible for providing necessary information to ensure the airworthiness of aircraft types, while the State of Registry, in this case CASA, must implement these directives within Australia. This regulatory framework ensures that Australian aviation remains compliant with international obligations and maintains high safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together facilitate the issuance of airworthiness directives (ADs) which are key regulatory instruments for ensuring the safety of aircraft and aeronautical products. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that promote the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations under these provisions require the State of Design to take primary responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 of the Convention on International Civil Aviation. This includes providing necessary information to States of Registry to ensure the aircraft's continued airworthiness. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of individual aircraft registered within its jurisdiction. For example, if a State of Design issues an AD for a type of aircraft on the Australian Register, CASA, as Australia's national airworthiness authority, must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
In the context of the Bell 206 model aircraft, CASA issued AD/BELL 206/67, which was subsequently assessed and cancelled due to the resolution of the unsafe condition. This cancellation took effect on 23 October 2008, and no replacement AD was required as the unsafe condition no longer existed. Given that this AD was cancelled in accordance with Australia's obligations under the Convention on International Civil Aviation, no public consultation was conducted, and the Office of Best Practice Regulation determined that ADs do not necessitate a Regulatory Impact Statement. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
The consequences for non-compliance with ADs are significant, as they are integral to ensuring the safety of aviation operations. While the specific penalties for breaches of ADs are not detailed in the provided text, non-compliance with regulatory directives under the Civil Aviation Act 1988 could result in civil or criminal penalties, including fines and potential imprisonment, depending on the severity of the breach and its impact on safety. CASA is responsible for enforcing these regulations and ensuring adherence to ADs to maintain the high safety standards required in the aviation industry.
