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.
CASA issued AD/PA-22/34, affecting Piper PA-22 model aircraft, in 1989. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been modified long ago.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes in the Airworthiness Engineering Branch, 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 in Australia, addressing issues related to the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were also formulated, enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These regulations are in line with international standards, particularly Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, plays a critical role in ensuring that aircraft on the Australian Register meet safety standards by issuing relevant ADs based on information from the State of Design. This legislative framework ensures that Australian aviation practices align with international safety standards while maintaining a regulatory burden that is proportionate to the risks involved.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide a comprehensive framework for the regulation of civil aviation in Australia, encompassing the issuance of airworthiness directives (ADs) for the purpose of ensuring safety in air navigation. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments themselves, mandate specific requirements necessary for the continuing airworthiness of aircraft, thereby ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). The application of these ADs extends to all aircraft registered in Australia, thereby affecting aircraft manufacturers, operators, and maintenance organisations within the jurisdiction. The geographic reach of these regulations is national, applying uniformly across Australia, and they do not include specific exclusions or thresholds beyond those types of aircraft or aeronautical products specifically identified in the ADs. Additionally, the authority to issue ADs may be extended or refined through subordinate instruments, ensuring the ongoing adaptation of regulations to technological advancements and safety considerations.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to enact regulations that are vital for the safety of air navigation. Complementing this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. It is important to note that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments governed by the provisions of the Legislative Instruments Act 2003.
Under the obligations imposed by Annex 8 to the Convention on International Civil Aviation, the State of Design, which is the country where an aircraft type is designed, bears the responsibility for ensuring the continuing airworthiness of the aircraft. This includes providing any necessary information to the States of Registry, which are the countries where the aircraft are registered. In Australia, CASA, as the national airworthiness authority, must assess the information provided by the State of Design and, if appropriate, issue an Australian AD to mandate the requirements for ensuring the continuing airworthiness of aircraft. The State of Registry, on the other hand, is responsible for the day-to-day oversight of the aircraft’s airworthiness within its jurisdiction.
CASA issued an airworthiness directive, AD/PA-22/34, concerning Piper PA-22 model aircraft, in 1989. After reviewing the directive, CASA has decided to cancel it, effective from 3 July 2008. This cancellation has been made without the need for public consultation, as it results in a reduction of the regulatory burden. Additionally, the Office of Best Practice Regulation has confirmed that ADs do not require a Regulatory Impact Statement. The cancellation of the AD does not necessitate a replacement, as all affected aircraft would have already been modified according to the previous requirements.
Failure to comply with airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines, and in severe cases, criminal charges. The specific penalties depend on the nature and severity of the breach, but they can include substantial fines for corporations and individuals. Additionally, CASA has the authority to take enforcement actions, such as grounding non-compliant aircraft, which can have significant operational and financial repercussions for operators.
