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 206/97 Amendment 2 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 was enacted to provide for the safety and efficiency of civil aviation and the regulation of air navigation services in Australia. This Act was introduced to address the need for comprehensive legislation governing civil aviation within the country, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. One such regulation, made under the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. The issuance and assessment of ADs are crucial for maintaining the continuing airworthiness of aircraft, aligning with Australia’s obligations under the Convention on International Civil Aviation. The ADs are legislative instruments that CASA, as Australia’s national airworthiness authority, issues to ensure compliance with international standards and safety requirements.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act empowers the Governor-General to issue regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these regulations extends to ensuring compliance with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design holds responsibility for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry, including Australia. CASA, as the national airworthiness authority, must evaluate and, if necessary, issue Australian ADs to enforce the requirements set by the State of Design. This regulatory process ensures that Australian-registered aircraft meet international safety standards, thereby safeguarding the safety of air navigation within Australia's jurisdiction.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework for the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs). Under section 98 of this Act, the Governor-General has the power to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for certain kinds of aircraft or aeronautical products. Section 39.001(5) of these regulations further specifies that an AD is a disallowable instrument, and therefore a legislative instrument under the Legislative Instruments Act 2003.
An AD is a directive issued to ensure the continuing airworthiness of aircraft types, and it is a crucial tool under Annex 8 to the Convention on International Civil Aviation. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to the States of Registry, which in turn are responsible for the individual aircraft's continuing airworthiness. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
In this context, CASA issued AD/BELL 206/97 Amendment 2, which affected Bell 206 model aircraft. However, this AD has been cancelled as of 23 October 2008, due to the resolution of the unsafe condition it was intended to address. Consequently, there was no need for public consultation on the cancellation, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD was 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.
The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA to ensure that all ADs issued are in line with international standards and obligations under the Convention on International Civil Aviation. Any failure to comply with an AD can lead to serious safety consequences and may result in enforcement actions by CASA. Although specific offences and penalties for non-compliance with ADs are not detailed in the text, such non-compliance could potentially lead to civil penalties, criminal charges, or both, depending on the severity of the breach and the potential risk posed to aviation safety.
