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 2005-16-01 affecting Boeing 747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/333, which will become effective on 27 October 2005.
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 legislative framework for the regulation of civil aviation in Australia, with a focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act, and these regulations can include the issuance of airworthiness directives (ADs) to ensure the safety of aircraft. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. The authority to issue these directives is grounded in international obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design is responsible for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry, including Australia. CASA, as Australia’s national airworthiness authority, must then assess this information and issue corresponding ADs to ensure compliance with international safety standards. The process of issuing such directives is intended to align with international best practices and to uphold the high safety standards expected within the Australian civil aviation sector.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia, ensuring compliance with international standards and the continuing airworthiness of aircraft. The Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and under regulation 39.001, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. The State of Design, which in this case is the United States for Boeing 747 model aircraft, holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and issue corresponding Australian ADs to mandate the required safety measures. This process is conducted without public consultation and does not require a Regulatory Impact Statement, as determined by the Office of Regulatory Review. ADs are integral to adhering to international agreements such as Annex 8 of the Convention on International Civil Aviation, and are issued in response to directives from the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to enact regulations for the Act’s purposes and in the interests of air navigation safety. This authority allows for the creation of detailed regulatory frameworks that ensure the safe operation of aircraft. One significant regulation, 39.001 of the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the power to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are formal instructions aimed at ensuring the continued airworthiness of aircraft, aligning with international standards set out in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act on CASA and other entities are substantial. CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design, which in the case of Boeing 747 aircraft, is the United States. If deemed appropriate, CASA is required to issue corresponding Australian ADs to mandate the necessary actions to maintain airworthiness. For example, following the issuance of US FAA AD 2005-16-01 for Boeing 747 aircraft, CASA has issued Australian AD/B747/333. This process ensures that Australian aircraft meet international safety standards. Additionally, the State of Registry, which in this context is Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction.
Failure to comply with the ADs can lead to significant legal consequences. Although the specific offences, penalties, or civil/criminal consequences are not detailed in the provided text, it is clear that non-compliance with ADs can result in enforcement actions by CASA. These actions might include grounding of non-compliant aircraft, fines, or other regulatory penalties. The statutory framework ensures that all parties adhere to safety standards, thereby maintaining the high level of safety within Australian civil aviation. The regulatory approach underscores the importance of stringent compliance to prevent any compromise on the safety of air navigation.
