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/AA-5/5 affecting Gulfstream AA-5 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-5/5. The cancellation will become effective on 4 June 2009. 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 regulate civil aviation within Australia, ensuring safety and efficiency in air navigation. Under this Act, the Governor-General has the authority to establish regulations to maintain air navigation safety, as seen in the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments for ensuring the continuing airworthiness of aircraft and aeronautical products. This legislative framework aligns with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design provide necessary information to ensure an aircraft type's continuing airworthiness. In the case of the Gulfstream AA-5 model aircraft, CASA issued and subsequently cancelled AD/AA-5/5, reflecting the resolution of the unsafe condition identified. This action was taken in accordance with Australia's international commitments and CASA's role as the national airworthiness authority, without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Governor-General to enact regulations for the safety of air navigation. Specifically, regulation 39.001 of these regulations mandates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs, as detailed in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, thus, legislative instruments according to section 6 of the Legislative Instruments Act 2003. The regulations apply to all entities involved in the operation, maintenance, and oversight of aircraft registered in Australia, ensuring compliance with international standards set forth by the International Civil Aviation Organization (ICAO) under Annex 8 of the Convention on International Civil Aviation. The ADs are primarily issued by the State of Design and are subject to assessment and potential issuance by CASA, Australia's national airworthiness authority, to maintain the continuing airworthiness of aircraft registered in Australia. This legislative framework ensures that all relevant parties adhere to the necessary safety standards and practices to prevent unsafe conditions in civil aviation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for ensuring the safety and airworthiness of aircraft operating in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations necessary for the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, and are subject to disallowance as per section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these regulations are significant for the entities they govern. The State of Design, responsible for the type design of an aircraft, must provide any necessary information to ensure the continuing airworthiness of that type to States of Registry, as stipulated under Annex 8 to the Convention on International Civil Aviation. Similarly, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft registered within its territory. In Australia, CASA, as the national airworthiness authority, is tasked with assessing information from the State of Design and issuing Australian ADs if necessary. This was exemplified in the case of AD/AA-5/5 affecting Gulfstream AA-5 model aircraft, which CASA assessed and subsequently cancelled, as the unsafe condition no longer existed.
Failure to comply with ADs can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in both civil and criminal penalties. Civil penalties can include fines, while criminal penalties can result in imprisonment. The exact penalties depend on the nature and severity of the breach, but the Act provides for significant deterrents to ensure compliance with airworthiness standards.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for ensuring the safety and airworthiness of aircraft in Australia. CASA’s role in issuing and enforcing ADs is central to this framework, with significant obligations and consequences for non-compliance. The cancellation of AD/AA-5/5 demonstrates the dynamic nature of airworthiness management, where directives are issued or rescinded based on the evolving safety landscape.
