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 EASA has issued AD 2007-0085 affecting Turbomeca Arriel 2B1 engines. The EASA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/ARRIEL//26, which will become effective on 5 April 2007.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations, including the issuance of airworthiness directives (ADs), to maintain the safety of air navigation. In the context of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, which serve as legislative instruments to enforce continuing airworthiness standards. In response to the State of Design's obligation under Annex 8 of the Convention on International Civil Aviation, CASA assesses and, if necessary, issues Australian ADs to align with the directives issued by other contracting states. This process ensures that Australian aircraft meet international safety standards and complies with Australia's commitments under the Convention.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives serve as legislative instruments, as outlined under subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The issuance of ADs is grounded in Australia's obligations under Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design holds responsibility for the continuing airworthiness of aircraft types, while the State of Registry ensures the airworthiness of individual aircraft. Consequently, when a State of Design, such as the European Aviation Safety Agency (EASA), issues an AD, CASA must evaluate this information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements of the originating State of Design. This legislative framework ensures that Australian aircraft maintain international safety standards, although the specific ADs do not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 provides a legislative framework for civil aviation in Australia, with section 98 granting the Governor-General the power to make regulations for the Act’s purposes. One such regulation, 39.001 under the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified aircraft types or aeronautical products. These ADs are considered disallowable instruments, and therefore legislative instruments as per section 6 of the Legislative Instruments Act 2003. This regulatory mechanism is essential to maintain the safety standards in the aviation industry, ensuring that all aircraft and related products meet necessary safety criteria.
Under these regulations, the State of Design has overarching responsibilities for the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. This involves providing all necessary information to the States of Registry to ensure the ongoing airworthiness of the aircraft. The State of Registry, in turn, is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. For example, when the European Aviation Safety Agency (EASA), as the State of Design for Turbomeca Arriel 2B1 engines, issues an AD, CASA must assess this information and, if necessary, issue an Australian AD to implement the requirements of the EASA directive.
The Civil Aviation Safety Regulations 1998 impose specific obligations on CASA and the State of Registry to ensure that aircraft maintain their airworthiness. CASA must evaluate any ADs issued by the State of Design and, where appropriate, issue corresponding Australian ADs to enforce the safety directives. This process underscores the collaborative nature of international aviation safety, where national authorities work in concert to uphold global safety standards. The ADs themselves are legally binding, requiring operators to comply with the specified safety measures to maintain the airworthiness of their aircraft.
Failure to comply with an AD can result in severe consequences, including both civil and criminal penalties. While the specific penalties are not detailed in the provided text, it is known that breaches of aviation regulations can lead to significant fines, suspension or revocation of aircraft operating certificates, and potential criminal charges for serious violations. These measures are in place to ensure that all stakeholders adhere to the stringent safety requirements designed to protect public safety and maintain the integrity of the aviation industry. The regulatory framework thus serves to deter non-compliance and to enforce adherence to safety standards rigorously.
