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 European Aviation Safety Authority (EASA) has issued AD 2007-0303 affecting British Aerospace BAe 146 and Avro 146-RJ model aircraft. EASA acts on behalf of the United Kingdom, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BAe 146/132, which will become effective on 13 March 2008.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish and regulate the safety of civil aviation within Australia, addressing the need for comprehensive governance and oversight of air navigation and aircraft safety. The Act empowers the Governor-General to issue regulations in the interests of aviation safety, with the Civil Aviation Safety Regulations 1998 further detailing these provisions. One of the key mechanisms under this legislative framework is the issuance of airworthiness directives (ADs), which are regulatory instruments used to ensure the continuing airworthiness of aircraft. These ADs are issued by the Civil Aviation Safety Authority (CASA) under the authority granted by regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs serve to implement the international standards set by the International Civil Aviation Organization (ICAO) and ensure compliance with the obligations of the Convention on International Civil Aviation. This legislative approach reflects Australia's commitment to harmonising its aviation safety regulations with international standards, thereby enhancing the safety of air navigation and protecting public interests.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. These directives are integral in ensuring the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The State of Design holds primary responsibility for the airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure compliance with airworthiness requirements. This is exemplified in the issuance of AD/BAe 146/132 by CASA, which responds to an AD issued by the European Aviation Safety Authority (EASA) on behalf of the United Kingdom, the State of Design for the British Aerospace BAe 146 and Avro 146-RJ model aircraft. The issuance of this AD adheres to Australia’s obligations under the Convention on International Civil Aviation and does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) aimed at ensuring the safety of air navigation. Specifically, section 98 of the Act allows the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Regulations empowers CASA to issue ADs for specific kinds of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, consequently, as legislative instruments under section 6 of the Legislative Instruments Act 2003.
These provisions impose obligations on CASA and other entities to ensure the continuing airworthiness of aircraft registered in Australia. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to the relevant States of Registry. In Australia, CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs. This process ensures that Australian aircraft comply with international safety standards and maintain airworthiness.
Non-compliance with the airworthiness directives issued under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant legal consequences. Offences related to the operation of aircraft not meeting the mandated airworthiness standards may be prosecuted under the Act. Penalties for breaches can include substantial fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, but they are intended to enforce strict compliance with airworthiness requirements to safeguard public safety.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust regulatory framework for ensuring the airworthiness of aircraft through the issuance of ADs. These regulations mandate that CASA and other relevant entities adhere to international standards and maintain strict oversight of aircraft operations. Failure to comply with these directives can lead to significant civil and criminal penalties, underscoring the importance of adhering to the prescribed airworthiness requirements.
