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 2006-0198 affecting Short Brothers SD3-30 model aircraft. The EASA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/SD3-30/48, which will become effective on 26 October 2006.
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 for the regulation of civil aviation in Australia, ensuring safety and efficiency in the sector. The 1988 Act empowers the Governor-General to make regulations to safeguard air navigation, with the Civil Aviation Safety Regulations 1998 further detailing the mechanisms for maintaining airworthiness standards. The introduction of airworthiness directives (ADs) under this regulatory framework addresses the need for ongoing safety oversight and compliance with international standards set by the Convention on International Civil Aviation. ADs are critical for ensuring that aircraft continue to meet necessary safety standards, with the Civil Aviation Safety Authority (CASA) responsible for issuing Australian ADs in response to directives from the State of Design. This legislative and regulatory structure ensures that Australia meets its international obligations while maintaining the highest standards of aviation safety domestically.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for ensuring the safety of air navigation in Australia, with a particular focus on the continuing airworthiness of aircraft and aeronautical products. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) that mandate specific requirements for certain types of aircraft. These ADs are considered legislative instruments and serve to implement international standards set by the International Civil Aviation Organization (ICAO) under Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the ongoing airworthiness of an aircraft type, issues ADs that may be adopted or adapted by States of Registry, such as Australia. CASA, as the national airworthiness authority, evaluates these directives and may issue Australian ADs to enforce the requirements on aircraft registered in Australia. The issuance of such directives is a direct response to international obligations and is not subject to public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The ADs are issued by CASA on behalf of the Governor-General under the authority granted by the Act, ensuring that Australian aviation safety standards align with international best practices.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. This regulatory power is vital for maintaining and enhancing the safety standards of aviation within Australia.
Entities governed by these regulations, including aircraft manufacturers, operators, and maintenance service providers, bear the responsibility of ensuring compliance with ADs. The State of Design has the primary obligation to ensure the continuing airworthiness of aircraft types, providing necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, must evaluate this information and, if necessary, issue corresponding Australian ADs. This ensures that Australian-registered aircraft meet the international safety standards stipulated by their respective States of Design.
Non-compliance with ADs can lead to significant legal consequences. Under the Civil Aviation Act 1988, breaches of ADs can result in both civil and criminal penalties. Civil penalties can include fines, while criminal penalties may involve imprisonment, reflecting the seriousness of ensuring air safety. The maximum penalties are specified in the relevant sections of the Act and can vary based on the severity of the breach.
It is also important to note that ADs issued under these regulations are considered legislative instruments, subject to disallowance under the Acts Interpretation Act 1901. This means that ADs must be reviewed and approved in accordance with the provisions of the Legislative Instruments Act 2003. The process ensures that ADs are formally and properly enacted, maintaining the integrity and enforceability of aviation safety regulations.
