CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 Emergency AD 2005-04-51 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/B747/324. Because of the potential seriousness of the defect, and the need for urgent action, this AD has been made effective on 18 February 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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, 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 and to ensure the safety of air navigation. One of the mechanisms through which this is achieved is via the issuance of airworthiness directives (ADs), which are legislative instruments made under the Act and the Civil Aviation Safety Regulations 1998. These directives mandate specific requirements to maintain the airworthiness of aircraft and aeronautical products, ensuring that they meet safety standards. In this context, the Civil Aviation (Airworthiness Directives) Instrument 2005 (F2005L00351) was introduced to address an urgent safety issue identified by the United States Federal Aviation Administration (FAA) concerning Boeing 747 model aircraft. Given the international obligations under the Convention on International Civil Aviation and the need for prompt action, the Civil Aviation Safety Authority (CASA), acting as Australia's national airworthiness authority, assessed the information and issued an Australian AD to mandate the requirements set by the FAA. This directive was made effective on 18 February 2005, reflecting the urgency of the situation.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for ensuring the safety of air navigation in Australia. Under this Act, the Governor-General can make regulations that pertain to the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as legislative instruments, subject to disallowance and the Legislative Instruments Act 2003. The application of these ADs extends to any aircraft registered in Australia, thereby impacting both domestic and international entities operating within Australia's jurisdiction. While the Act does not specify particular exclusions or thresholds, the necessity of issuing an AD is dictated by the potential seriousness of a defect and the urgency required to address it. The issuance of an AD is driven by the obligations under the Convention on International Civil Aviation, particularly those concerning the continuing airworthiness of aircraft, and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Governor-General to make regulations in the interests of the safety of air navigation, and allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Regulation 39.001(5) of the Civil Aviation Safety Regulations 1998 further clarifies that an AD is a disallowable instrument and thus, a legislative instrument under the Legislative Instruments Act 2003. This regulatory framework is established to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with international standards under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions include the responsibility of the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types and the duty of the State of Registry to develop or adopt requirements for the continuing airworthiness of individual aircraft. For example, when the United States, as the State of Design for Boeing 747 model aircraft, issues an AD, CASA, as Australia’s national airworthiness authority, must assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements. This process is integral to maintaining safety standards and ensuring compliance with international obligations.
In terms of potential breaches and consequences, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish legal frameworks that can result in civil or criminal penalties for non-compliance with ADs. While the specific penalties are not detailed in the provided text, breaches of safety regulations can typically result in fines, imprisonment, or both, depending on the severity and intent behind the violation. The Act ensures that those who fail to comply with ADs face appropriate consequences to uphold the high standards of air safety and public protection.
Furthermore, the legislative process for issuing ADs, as detailed in the Civil Aviation Safety Regulations 1998, requires CASA to act promptly in response to international safety directives without the need for public consultation or a Regulatory Impact Statement, especially in cases of urgent safety concerns. This streamlined process underscores the importance of rapid response in addressing potential safety hazards, ensuring that aircraft continue to meet necessary safety standards without unnecessary delay.
