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 206/17 Amendment 1 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 by the Parliament of Australia, establishes the framework for ensuring the safety and efficiency of civil aviation within Australia. It was introduced to address the need for comprehensive regulation of civil aviation to protect public safety and maintain the integrity of the national airspace. Under this Act, the Civil Aviation Safety Regulations 1998 were subsequently created, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft. These directives are crucial for maintaining the safety standards of aircraft registered in Australia and are issued in accordance with international conventions, such as Annex 8 to the Convention on International Civil Aviation. The ADs serve as a means for the State of Design and the State of Registry to communicate necessary safety information and actions to ensure that aircraft remain airworthy throughout their operational life.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes a framework for the regulation of airworthiness directives (ADs) in Australia. Under this legislative framework, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs concerning types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, which are legislative instruments, are issued pursuant to the authority conferred by section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998. Such ADs must align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, which governs the continuing airworthiness of aircraft. The State of Design, typically the country where the aircraft is designed, has the primary responsibility for issuing continuing airworthiness information, while the State of Registry, where the aircraft is registered, is responsible for ensuring compliance with these directives. This legislative scope applies nationally across Australia and involves entities such as aircraft manufacturers, operators, and CASA, ensuring a consistent approach to aviation safety. While ADs are issued under this regulatory scheme, there are no stated exclusions or exemptions in the provided text, and their issuance is subject to international obligations and national safety standards.
Key Provisions
The Civil Aviation Act 1988 provides the legislative foundation for regulating airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to issue regulations that promote the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and are subject to disallowance. Moreover, under Annex 8 of the Convention on International Civil Aviation, the State of Design holds responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is tasked with ensuring the continuing airworthiness of individual aircraft within its jurisdiction.
In compliance with these provisions, CASA, as Australia’s national airworthiness authority, is obligated to evaluate ADs issued by States of Design. When an AD is issued by a State of Design for a type of aircraft registered in Australia, CASA must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards. The State of Registry, in this case, CASA, is responsible for developing or adopting the necessary requirements to ensure that aircraft continue to meet airworthiness standards.
An example of this process is seen in AD/BELL 206/17 Amendment 1, which affected Bell 206 model aircraft. CASA has assessed the AD and, due to Australia’s obligations under the Convention on International Civil Aviation, has cancelled this AD effective 23 October 2008. The cancellation was made without public consultation, as it was determined that ADs do not require a Regulatory Impact Statement. The Manager, Systems and New Technologies in the Airworthiness Engineering Group issued this AD on behalf of CASA in accordance with subsection 84A(2) of the Act.
Breaching the requirements of an AD can lead to significant legal consequences. If an operator fails to comply with an AD, CASA may take enforcement action, which can include fines or other penalties. The severity of the penalty depends on the nature and extent of the non-compliance. Under the Civil Aviation Act 1988, offences related to airworthiness can result in substantial fines, imprisonment, or both. Specifically, non-compliance with an AD can be prosecuted as an offence under section 24 of the Act, which can lead to penalties of up to $222,200 for corporations and $44,440 for individuals, as well as potential imprisonment terms. Therefore, it is crucial for aircraft operators and other relevant parties to adhere to all ADs to avoid these serious legal repercussions.
