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 2006-22-15 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/B747/323, Amendment 2, which will become effective on 2 August 2007. This AD cancels and replaces the previous issue.
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 the regulation of civil aviation in Australia, addressing the need for clear and effective governance to ensure the safety and efficiency of the aviation industry. This Act grants the Governor-General the authority to make regulations in the interest of air navigation safety, as exemplified by the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments designed to maintain the continuing airworthiness of aircraft, in alignment with international standards set by the Convention on International Civil Aviation. This legislative framework ensures that Australia meets its international obligations and maintains high safety standards within its national airspace.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, authorise the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. These directives apply to specific kinds of aircraft or aeronautical products and are aligned with the requirements under Annex 8 to the Convention on International Civil Aviation. The ADs are issued in response to continuing airworthiness information provided by the State of Design and are subject to assessment by CASA, which acts as Australia's national airworthiness authority. Once assessed, CASA issues corresponding Australian ADs to mandate the requirements of the original State of Design. For instance, in response to a US Federal Aviation Administration AD affecting Boeing B747 model aircraft, CASA issued Australian AD/B747/323, Amendment 2. This AD, which cancels and replaces the previous issue, will become effective on 2 August 2007. Notably, the issuance of ADs does not require consultation with the Australian public nor a Regulatory Impact Statement, as they are deemed necessary under Australia's obligations under the Convention on International Civil Aviation. The ADs are legislative instruments and are made by CASA under the authority of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) in Australia, as outlined in section 98 and regulation 39.001 respectively. Under these provisions, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific types of aircraft or aeronautical products. These directives are legislative instruments, as stated in subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. The ADs serve to maintain the continuing airworthiness of aircraft, aligning with international standards set by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the primary responsibility for ensuring airworthiness. The State of Registry, in this case CASA, must then adopt and enforce these requirements for individual aircraft registered in Australia.
The obligations imposed by these ADs are significant. For instance, the State of Design, which in the case of Boeing B747 aircraft is the United States, is responsible for issuing ADs based on safety concerns. CASA, as Australia’s national airworthiness authority, must review these directives and, if deemed necessary, issue corresponding Australian ADs to ensure compliance. This process ensures that Australian-registered aircraft meet the international safety standards set by the State of Design. Additionally, under Annex 8, the State of Registry must implement and enforce these requirements to guarantee the continuing airworthiness of all aircraft within its jurisdiction. This includes conducting inspections, maintenance, and ensuring that all necessary modifications are carried out in accordance with the ADs.
Failure to comply with ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can result in imprisonment. The specific penalties are not detailed in the provided text, but they are significant enough to ensure adherence to the safety regulations. Additionally, operating an aircraft that does not comply with an AD can lead to the aircraft being grounded, which can have severe operational and financial repercussions for the aircraft owner or operator. Therefore, it is imperative that all stakeholders, including aircraft manufacturers, operators, and maintenance personnel, are fully aware of and comply with the requirements of any ADs issued under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998.
