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 FAA has issued AD 2005-03-02 affecting Boeing Model 737 aircraft. USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/237, which will become effective on 14 April 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, enacted by the Parliament of Australia, was introduced to ensure the safety of air navigation and to establish a framework for the regulation of civil aviation within Australia. The Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft, ensuring they meet safety standards both nationally and internationally. The ADs are legislative instruments subject to disallowance, and they are issued in compliance with international obligations under the Convention on International Civil Aviation. This legislative framework allows CASA to act on ADs issued by the State of Design and to issue corresponding Australian ADs to mandate the necessary requirements on aircraft registered in Australia. The process is designed to uphold the safety standards set by the international community and to address any safety issues identified by the relevant State of Design.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) which are essential for ensuring the continuing airworthiness of aircraft registered in Australia. Under these legislative instruments, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products, thereby enforcing safety standards mandated by the State of Design. These directives are legislative instruments and serve to ensure compliance with international standards set by the International Civil Aviation Organization (ICAO). The ADs are typically issued in response to an AD issued by the State of Design, such as the Federal Aviation Administration (FAA) for U.S.-designed aircraft, and are designed to maintain the safety of air navigation within Australia. This legislative framework ensures that CASA, as Australia’s national airworthiness authority, can mandate necessary requirements derived from international obligations, without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework for airworthiness directives (ADs) under section 98 and regulation 39.001, respectively. Regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003 classify these ADs as disallowable instruments and legislative instruments, respectively. In essence, ADs are legally binding mandates aimed at ensuring the continuing airworthiness of aircraft.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties such as CASA and the State of Registry are substantial. The State of Design, in this case, the United States, bears the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to the State of Registry. In Australia, CASA acts as the national airworthiness authority and must assess the information provided by the State of Design. If an AD is deemed necessary, CASA must then issue a corresponding Australian AD to ensure compliance with the airworthiness standards. This process is particularly evident in the case of the Boeing 737 aircraft, where CASA issued AD/B737/237 following the Federal Aviation Administration's (FAA) AD 2005-03-02.
Failure to comply with the ADs can lead to serious consequences. Under section 98 of the Civil Aviation Act 1988, CASA has the authority to enforce compliance with ADs, and non-compliance can result in significant penalties. The exact nature of these penalties is not detailed in the provided text, but generally, violations of airworthiness regulations can lead to civil or criminal penalties, including fines and imprisonment. Additionally, non-compliance can result in the grounding of aircraft, which has severe operational and financial implications for airlines and other aviation entities.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for issuing and enforcing ADs to ensure the continuing airworthiness of aircraft. The obligations placed on CASA and the State of Registry are clear, and the potential consequences of non-compliance are significant, underscoring the critical importance of adhering to these regulations.
