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/CON/58 affecting all Teledyne Continental Motors piston engines. CASA has assessed this AD and as a result has cancelled Australian AD/CON/58. 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 provide a comprehensive framework for the regulation of civil aviation in Australia, addressing gaps in aviation safety and regulation that existed prior to its introduction. The Act grants the Governor-General the authority to make regulations necessary for the safety of air navigation, which includes the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. This legislative framework ensures that Australia meets its international obligations under the Convention on International Civil Aviation, particularly with respect to the continuing airworthiness of aircraft. The Act also mandates that CASA, as Australia’s national airworthiness authority, must assess and respond to airworthiness directives issued by States of Design, thereby ensuring that Australian aircraft meet international safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) playing a pivotal role in ensuring the continuing airworthiness of aircraft registered in Australia. The Act applies to all entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers, as well as to all aircraft and aeronautical products registered or operated within Australia. The ADs, as legislative instruments, extend to mandating safety requirements for specific types of aircraft or aeronautical products based on the assessment of continuing airworthiness by CASA. These directives are made in accordance with international standards set by the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design is responsible for providing continuing airworthiness information to the States of Registry, including Australia. CASA, as Australia’s national airworthiness authority, must evaluate the information provided by the State of Design and, if necessary, issue an Australian AD to enforce the required safety measures. The application of these regulations is nationwide, covering all aircraft within Australia’s jurisdiction, and there are no specific exclusions mentioned in the text. The legislative process for ADs is governed by the Legislative Instruments Act 2003, which recognises ADs as disallowable instruments, subject to certain parliamentary procedures.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 detail the processes for issuing airworthiness directives (ADs). Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments under the Acts Interpretation Act 1901, meaning they are considered legislative instruments. This regulatory framework is established to ensure compliance with the Convention on International Civil Aviation, particularly Annex 8, which designates the State of Design as responsible for the continuing airworthiness of aircraft types and mandates the dissemination of necessary information to States of Registry.
The obligations imposed by these regulations are primarily centred on ensuring the continuing airworthiness of aircraft. The State of Design is tasked with providing necessary information to maintain airworthiness, while the State of Registry must develop or adopt requirements to ensure this. In Australia, CASA assumes the role of the national airworthiness authority and is responsible for assessing information from the State of Design and issuing Australian ADs as necessary. This process is exemplified by the issuance and subsequent cancellation of Australian AD/CON/58, which affected all Teledyne Continental Motors piston engines. CASA assessed the AD and determined that the unsafe condition had been resolved, leading to the cancellation of the AD without the need for a replacement.
There are no public consultations required for the issuance or cancellation of ADs, as determined by the Office of Best Practice Regulation, which found that ADs do not necessitate a Regulatory Impact Statement. The creation and amendment of ADs are carried out by CASA officials, specifically the Manager Systems and New Technologies within the Airworthiness Engineering Group, in accordance with subsection 84A(2) of the Civil Aviation Act 1988. This process ensures that ADs are issued or cancelled based on safety considerations and compliance with international standards.
The consequences of non-compliance with ADs are significant. Failure to adhere to an AD can result in various civil and criminal penalties. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines. Additionally, serious violations may result in criminal penalties, including imprisonment. The maximum penalties for offences under the Act can vary depending on the severity of the breach and the specific provisions of the Act. These measures underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
