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 United States FAA has issued AD 97-01-10 affecting Boeing 737 model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/271, which will become effective on 19 January 2006.
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, New Technologies and Systems, 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 a coordinated approach to safety, efficiency, and economic growth in the aviation sector. This legislation grants the Civil Aviation Safety Authority (CASA) the authority to issue regulations, including airworthiness directives, to ensure the safety of air navigation as outlined in section 98. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA is empowered to issue airworthiness directives for specific types of aircraft or aeronautical products. This authority is exercised in accordance with international standards set by the International Civil Aviation Organization (ICAO), specifically under Annex 8, which assigns responsibility for continuing airworthiness to the State of Design. In the case of international airworthiness directives, such as the one issued by the United States Federal Aviation Administration (FAA) affecting Boeing 737 models, CASA assesses the directive and, if necessary, issues a corresponding Australian airworthiness directive to align with international obligations and maintain the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations necessary for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. This regulatory power is exercised under the broader obligations of Australia as a signatory to the Convention on International Civil Aviation, where the State of Design retains overall responsibility for the continuing airworthiness of an aircraft type. CASA, acting as Australia’s national airworthiness authority, is mandated to assess any relevant ADs issued by States of Design and, if deemed necessary, issue corresponding Australian ADs to ensure compliance with international safety standards. This process ensures that aircraft registered in Australia meet the necessary safety requirements, thereby maintaining the safety of air navigation as intended by the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for the issuance and management of airworthiness directives (ADs). According to section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifies that the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. Under subregulation 39.001(5), an AD is considered a disallowable instrument under the Acts Interpretation Act 1901, and thus a legislative instrument in accordance with the Legislative Instruments Act 2003.
The obligations under this legislation are primarily concerned with maintaining the continuing airworthiness of aircraft. The State of Design, which is responsible for the initial airworthiness of a particular aircraft type, must provide necessary information to ensure its continuing airworthiness. This responsibility is codified under Annex 8 to the Convention on International Civil Aviation. The State of Registry, on the other hand, is responsible for the ongoing airworthiness of individual aircraft registered within its jurisdiction. When a State of Design issues an AD, the State of Registry, in this case CASA as Australia's national airworthiness authority, must assess this information and, if necessary, issue a corresponding AD for aircraft registered in Australia. This ensures that Australian aircraft meet the safety standards set by the relevant State of Design.
Failure to comply with an AD can have serious legal consequences. Although the specific penalties are not detailed in the provided text, generally, non-compliance with ADs can result in both civil and criminal penalties. Civil penalties can include fines and other financial penalties, while criminal penalties can include imprisonment. The severity of the penalty often depends on the nature of the breach and its impact on aviation safety. Additionally, non-compliance can lead to the grounding of aircraft, which can have significant financial and operational repercussions for airlines and other aviation entities.
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. These regulations impose specific obligations on the States of Design and Registry to ensure the safety of aircraft, and they provide the legal basis for CASA to issue ADs in response to international safety requirements. Failure to comply with these directives can result in severe civil and criminal penalties.
