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 2008-23-09 affecting Boeing B727 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B727/214, which will become effective on 15 January 2009.
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 & Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a framework for the regulation of civil aviation in Australia, addressing the need for a cohesive and comprehensive legislative foundation to ensure safety and efficiency in the industry. The Act empowers the Governor-General to make regulations for the purposes of the Act, particularly in relation to the safety of air navigation. One such regulation, detailed in the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. The ADs issued by CASA, such as AD/B727/214 for Boeing B727 model aircraft, reflect the authority's role in ensuring that international safety standards are effectively implemented within Australia. This legislative framework and regulatory approach are essential for fulfilling Australia's commitment to international aviation safety standards while ensuring the safe operation of aircraft within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 provides the legislative framework for the regulation of air navigation safety in Australia, and under this Act, the Civil Aviation Safety Regulations 1998 permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments designed to ensure the continuing airworthiness of aircraft, and are issued by CASA in accordance with Australia's obligations under the Convention on International Civil Aviation. When a State of Design issues an AD, CASA is required to assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. For example, in response to the US Federal Aviation Administration's AD 2008-23-09 affecting Boeing B727 model aircraft, CASA issued Australian AD/B727/214, which became effective on 15 January 2009. Given the international nature of these directives and the lack of public consultation required, no Regulatory Impact Statement is deemed necessary for these ADs.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation, particularly through the issuance of airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations in the interests of safety, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. An AD, as defined in subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus, it is a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and Regulations primarily focus on maintaining the continuing airworthiness of aircraft. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has the responsibility to provide necessary information to ensure the airworthiness of an aircraft type. Consequently, the State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA must assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design.
In the case of the Boeing B727 model aircraft, the US Federal Aviation Administration (FAA) issued AD 2008-23-09. Given that the USA is the State of Design, CASA has assessed this directive and subsequently issued Australian AD/B727/214, effective from 15 January 2009. This AD, issued due to Australia’s obligations under the Convention on International Civil Aviation and in response to the relevant State of Design’s directive, did not undergo public consultation. The Office of Best Practice Regulation has also determined that such ADs do not require a Regulatory Impact Statement.
The AD in question was made by the Manager, Airframes & Structures in the Airworthiness Engineering Group on behalf of CASA, in accordance with subsection 84A(2) of the Act. The issuance of ADs carries significant implications, including potential civil and criminal consequences for non-compliance. Failure to adhere to the directives can result in severe penalties, reflecting the critical importance of these regulations in maintaining aviation safety standards.
