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 2005-23-07 affecting Boeing 727 model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B727/199, which will become effective on 13 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, 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 regulate civil aviation in Australia and ensure the safety of air navigation. Under section 98, the Governor-General is empowered to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. This authority is exercised through the Civil Aviation Safety Regulations 1998, which, among other provisions, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft as mandated by international standards, specifically Annex 8 to the Convention on International Civil Aviation, which places the responsibility on the State of Design for the continuing airworthiness of aircraft types. Consequently, when a State of Design issues an AD, CASA, as Australia's national airworthiness authority, must evaluate the information and, if necessary, issue a corresponding Australian AD. This legislative framework ensures that Australia complies with international obligations while safeguarding the safety and airworthiness of aircraft registered within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively provide the framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation in Australia. The Act applies to entities such as the Civil Aviation Safety Authority (CASA), which is Australia’s national airworthiness authority, and the aircraft owners or operators who must comply with the ADs issued by CASA. These regulations extend to all aircraft registered in Australia, irrespective of whether they are manufactured domestically or internationally, and thus cover a broad spectrum of aviation activities. The application of these regulations is not limited geographically within Australia but is in compliance with international standards set by the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and State of Registry. ADs, as legislative instruments, are subject to disallowance under the Acts Interpretation Act 1901, and they do not require public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review. The issuance of ADs by CASA is a direct response to obligations under international aviation agreements and is a critical tool in maintaining the continuing airworthiness of aircraft.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, allows the Governor-General to make regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003, as they are disallowable instruments as per section 46A of the Acts Interpretation Act 1901. This framework ensures that ADs are systematically issued to maintain the safety and airworthiness of aircraft.
The Act imposes certain obligations on CASA and other relevant authorities. For example, CASA must assess ADs issued by the State of Design, such as the United States Federal Aviation Administration (FAA), to ensure they meet the necessary safety standards. If appropriate, CASA must then issue an Australian AD to mandate the requirements of the State of Design for aircraft registered in Australia. This process underscores CASA’s role as Australia’s national airworthiness authority, ensuring compliance with international standards set forth in Annex 8 to the Convention on International Civil Aviation.
The State of Registry, which is responsible for the continuing airworthiness of individual aircraft registered in Australia, must also develop or adopt requirements to ensure compliance with ADs. This ensures that all aircraft operating within Australian airspace meet the necessary safety standards. Moreover, the State of Design must provide any necessary information to ensure the continuing airworthiness of an aircraft type, reinforcing the collaborative nature of international aviation safety efforts.
Failure to comply with ADs can lead to significant legal consequences. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, non-compliance with ADs could potentially lead to enforcement actions by CASA, including fines and other penalties. The severity of these penalties would depend on the nature and extent of the non-compliance, but they serve as a deterrent to ensure adherence to safety regulations. The overarching aim of these provisions is to maintain the highest safety standards in Australian civil aviation.
