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 2000-25-07 affecting Boeing 737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/262, which will become effective on 22 December 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 regulate civil aviation in Australia, ensuring safety and efficiency in the industry. One of its provisions allows the Governor-General to make regulations that promote the safety of air navigation. Specifically, under section 98, the Civil Aviation Safety Regulations 1998 were established, which permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. The purpose of ADs is to maintain the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The enactment of this Act and its regulations addresses the need for a robust framework to manage and oversee the safety of civil aviation in Australia, fulfilling the country’s obligations under international conventions and ensuring the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the safety and airworthiness of aircraft and aeronautical products within Australia. Under this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) as legislative instruments, ensuring compliance with international standards and obligations as stipulated in Annex 8 to the Convention on International Civil Aviation. The ADs apply to specific types of aircraft or aeronautical products and are issued in response to identified safety issues. These directives are mandated by the State of Design, which must provide necessary information to ensure continuing airworthiness. The State of Registry, CASA in the case of Australia, must assess this information and issue corresponding Australian ADs where necessary. The issuance of these ADs does not require public consultation or a Regulatory Impact Statement, as they are aligned with international obligations and safety standards.
The geographic reach of these regulations is national, and they apply to all aircraft registered in Australia, regardless of where they are manufactured. The application is not limited by state or territory boundaries but adheres to international conventions. While the Act broadly applies to the aviation industry and all entities involved in the manufacture, maintenance, and operation of aircraft, specific ADs target particular aircraft types or products based on identified safety concerns. There are no stated exclusions or exemptions in the issuance of ADs, which are critical for maintaining the safety and airworthiness of aircraft. The authority to extend or restrict the application of ADs can be found in subordinate instruments, ensuring flexibility in addressing emerging safety issues.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 98 of the Civil Aviation Act 1988 enables the Governor-General to make regulations in the interest of air navigation safety. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments per section 6 of the Legislative Instruments Act 2003.
The Civil Aviation Safety Regulations 1998 and Annex 8 to the Convention on International Civil Aviation outline the obligations of the State of Design and the State of Registry. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure airworthiness to appropriate States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. In this context, when a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
In the case of the Boeing 737 model aircraft, the United States Federal Aviation Administration (FAA) issued AD 2000-25-07. CASA assessed this AD and subsequently issued Australian AD/B737/262, effective from 22 December 2005. As this AD is issued due to Australia’s obligations under the Convention on International Civil Aviation and in response to an AD from the relevant State of Design, no public consultation was undertaken on this AD. Furthermore, the Office of Regulatory Review determined that ADs do not require a Regulatory Impact Statement. The AD was 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.
The issuance of ADs imposes specific obligations on CASA and aircraft operators. CASA must ensure that ADs issued in response to international directives are assessed and, if deemed necessary, translated into Australian ADs. Aircraft operators are obligated to comply with ADs by following the specified maintenance, inspection, and repair actions within the prescribed timeframes. Failure to comply with ADs can lead to serious safety risks and may result in aircraft being grounded. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the penalties for non-compliance with ADs, which may include fines and potential criminal charges. The severity of the penalties can depend on the nature of the non-compliance and the impact on aviation safety.
