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.
Transport Canada has issued AD CF-2007-05 affecting Bombardier DHC-8-400 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/130, which will become effective on 2 August 2007.
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, enacted by the Australian Parliament, provides the framework for the regulation of civil aviation in Australia, with the primary objective of ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations, including the issuance of airworthiness directives (ADs), to maintain the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail the processes and requirements for ADs, which are legislative instruments under the Legislative Instruments Act 2003. These directives are critical in ensuring the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation, where the State of Design retains overall responsibility for the airworthiness of an aircraft type, while the State of Registry ensures the airworthiness of individual aircraft. The Civil Aviation Safety and Standards Agency (CASA) issues Australian ADs in response to those issued by the relevant State of Design, thereby fulfilling Australia’s international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. This regulatory framework applies to all types of aircraft registered in Australia, thereby impacting aircraft owners, operators, and maintenance providers within the country. Geographically, the legislation applies on a national scale, aligning with Australia's obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates the State of Design's responsibility for the continuing airworthiness of aircraft types. CASA, as the national airworthiness authority, assesses and may issue Australian ADs in response to ADs from the relevant State of Design. This process ensures that Australian registered aircraft meet international safety standards. The issuance of an AD, such as AD/DHC-8/130 for Bombardier DHC-8-400 model aircraft, does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review, given its basis in international obligations and the nature of the regulatory instrument.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 contain provisions that allow for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, given their disallowable nature under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these regulations are twofold. Firstly, the State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure the continuing airworthiness of that type. Secondly, the State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, is required to assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian-registered aircraft meet international safety standards.
There are significant consequences for non-compliance with ADs. Under section 96 of the Civil Aviation Act 1988, it is an offence to operate an aircraft in a manner that contravenes a direction issued under the Act, which includes ADs. The maximum penalty for such an offence is a fine of up to 200 penalty units, which, as of 2023, equates to approximately AUD 42,500 for individuals and AUD 212,500 for corporations. Additionally, under section 98 of the Act, CASA has the authority to issue a notice directing the operator of the aircraft to comply with the AD, and failure to comply can result in the grounding of the aircraft, thus preventing it from operating until the necessary compliance measures are taken.
Furthermore, CASA has the authority to take legal action against those who fail to comply with ADs, which can result in both civil and criminal penalties. Civil penalties can include fines and the imposition of compliance orders, while criminal penalties can include imprisonment. For example, under section 91 of the Act, an individual who knowingly contravenes an AD can be fined up to 200 penalty units and/or imprisoned for up to two years. Corporations can face even higher penalties, with fines reaching up to 10,000 penalty units and imprisonment for up to five years. These stringent measures underscore the importance of adhering to ADs to ensure the safety of air navigation.
