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/T53/8 affecting AlliedSignal (Lycoming) turbine engines T53 series. CASA has assessed this AD and as a result has cancelled Australian AD/T53/8. The cancellation will become effective on 30 July 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, enacted by the Commonwealth Parliament, provides the legislative framework for the regulation of civil aviation in Australia. In addressing the need for maintaining the safety and airworthiness of aircraft, the Act empowers the Governor-General to issue regulations, including the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products. These directives are crucial for ensuring that aircraft remain airworthy and safe for operation, and are a legislative instrument under the Legislative Instruments Act 2003. The Civil Aviation Act 1988 thus plays a pivotal role in upholding international aviation safety standards, as it enables CASA to act on directives issued by aircraft design states and to mandate specific requirements for aircraft registered in Australia, thereby fulfilling Australia's obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for issuing airworthiness directives (ADs) in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs to ensure the continuing airworthiness of aircraft and aeronautical products. These ADs apply to all aircraft registered in Australia, irrespective of their type or use, and are intended to address safety concerns identified by the State of Design or by CASA. Geographic reach extends to all airspace within Australia’s jurisdiction, including territorial waters and designated airspace over international waters where Australian-registered aircraft are operating. The Act and regulations do not specify exclusions or exemptions from the application of ADs, although certain conditions or circumstances may be addressed in individual directives. Subordinate instruments, such as specific ADs, may extend or restrict the application of the regulations, and these are issued by CASA in accordance with its statutory powers. The process of issuing and cancelling ADs is subject to international obligations under the Convention on International Civil Aviation, and as such, may not always involve public consultation or detailed regulatory impact assessments.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance and management of airworthiness directives (ADs), as detailed in section 98 and regulation 39.001 respectively. These directives are tools used to ensure the safety and airworthiness of aircraft and aeronautical products, and they are legislative instruments as per subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. Under these regulations, the Civil Aviation Safety Authority (CASA) can issue ADs that are binding on aircraft owners and operators, ensuring that any identified safety issues are addressed.
The obligations imposed by these regulations include the requirement for the State of Design to provide necessary information for the continuing airworthiness of an aircraft type to the States of Registry, as per Annex 8 to the Convention on International Civil Aviation. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft registered within its jurisdiction. When an AD is issued by a State of Design, CASA, as Australia's national airworthiness authority, is tasked with assessing this information and, if appropriate, issuing an Australian AD to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft comply with international safety standards.
Failure to comply with an airworthiness directive can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in a range of civil and criminal penalties. For example, if an aircraft is operated in a manner that contravenes an AD, the operator may face fines and potential imprisonment. The severity of the penalty often depends on the nature of the offence and the potential risk posed to safety. In some cases, CASA may also suspend or revoke an aircraft's certificate of airworthiness, effectively grounding the aircraft until the required actions are taken to bring it into compliance with the AD.
The Civil Aviation Safety Regulations 1998 also outline specific offences and penalties for non-compliance with ADs. For instance, section 39.049 of the regulations states that an aircraft must not be operated in a manner that contravenes an AD. If an offence is committed, the maximum penalty can include fines and imprisonment, with the exact amount determined by the seriousness of the offence and the risk it poses to aviation safety. CASA is responsible for enforcing these regulations, and it has the authority to take enforcement actions against non-compliant aircraft operators. This includes issuing fines, suspending or revoking airworthiness certificates, and pursuing legal action where necessary to ensure compliance with the ADs.
