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 US FAA has issued AD 2006-24-05 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/353, which will become effective on 15 February 2007.
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, Airframes 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 a comprehensive legal framework for civil aviation in Australia, addressing various aspects of air navigation, safety, and regulation. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. One significant regulation under this Act is the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs, which are legislative instruments, are critical for maintaining the continuing airworthiness of aircraft and ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). The process of issuing these ADs is integral to Australia's obligations under the Convention on International Civil Aviation, particularly in aligning with the responsibilities of the State of Design and the State of Registry for individual aircraft.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, establish the legislative framework governing airworthiness directives (ADs) in Australia. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products to ensure the safety of air navigation, as per section 98 of the Act. Such ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are subject to disallowance. They also fall under the purview of the Legislative Instruments Act 2003. These ADs primarily apply to aircraft registered within Australia, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of aircraft types and mandates the State of Registry to enforce these standards. CASA, acting as Australia’s national airworthiness authority, is required to assess and, if necessary, issue Australian ADs in response to directives from the State of Design. This process ensures compliance with international obligations and maintains the safety standards of aircraft operating within Australian jurisdiction.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Under these provisions, the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. It is important to note that these ADs, as per subregulation 39.001(5), are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, in accordance with section 6 of the Legislative Instruments Act 2003, they are considered legislative instruments.
The obligations imposed by these regulations on CASA and other parties are substantial. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type. This responsibility includes the provision of necessary information to the State of Registry to ensure the aircraft's airworthiness. The State of Registry, in turn, must develop or adopt appropriate requirements to maintain the continuing airworthiness of the aircraft within its jurisdiction. When an AD is issued by a State of Design, such as the United States Federal Aviation Administration (FAA) in the case of AD 2006-24-05 for Boeing B747 model aircraft, CASA must assess the directive and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements outlined by the State of Design.
The consequences for non-compliance with these airworthiness directives are significant. Although the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail offences, penalties, or consequences for breaching ADs, the overarching legal framework provides a basis for enforcement. Failure to comply with an AD could result in severe civil or criminal penalties, including fines and imprisonment, as provided under other sections of the Civil Aviation Act 1988. Additionally, the authority to enforce compliance is granted under section 84A of the Act, which empowers CASA to take appropriate action against entities that do not adhere to the mandated airworthiness requirements.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for the issuance and enforcement of airworthiness directives. CASA's role in assessing and issuing these directives is crucial in maintaining the safety standards of aircraft registered in Australia. The obligations on the State of Design and State of Registry, as well as the potential legal consequences for non-compliance, underscore the importance of adhering to these regulations.
