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 87-17-10 affecting GENERAL DYNAMICS (Convair) Models 340 and 440 aircraft. The United States is the State of Design for these aircraft models. CASA has assessed this AD and has issued Australian AD/CONVAIR/24, which will become effective on 8 June 2006.
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 ensure the safety of air navigation and provide a regulatory framework for civil aviation in Australia. Under this Act, the Governor-General has the authority to make regulations for air navigation safety, including the issuance of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. ADs serve as a means to mandate requirements for the continuing airworthiness of aircraft, ensuring compliance with international standards as stipulated in Annex 8 of the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) assumes the role of the national airworthiness authority, responsible for assessing ADs issued by the States of Design and issuing corresponding Australian ADs when necessary. This legislation aims to harmonise Australia's aviation safety standards with international practices, thereby enhancing the overall safety of air navigation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of 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. This legislative framework applies to all entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers, with the overarching goal of ensuring the safety of air navigation. The geographic scope of these regulations is national, as they are enforced across Australia. The issuance of ADs is mandatory when corresponding directives are issued by the State of Design, as per international obligations under the Convention on International Civil Aviation. These ADs are legislative instruments and are subject to disallowance provisions under the Acts Interpretation Act 1901. Importantly, no public consultation is required for such ADs as they stem from international obligations and are in direct response to directives issued by the State of Design. Additionally, CASA has determined that these ADs do not necessitate a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to make regulations to ensure the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a legislative instrument under the Legislative Instruments Act 2003 and are critical for maintaining the continuing airworthiness of aircraft, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure that the aircraft remain airworthy. Consequently, when a State of Design, such as the United States, issues an AD for a type of aircraft registered in Australia, CASA is required to assess this information and, if necessary, issue a corresponding Australian AD to enforce the requirements outlined by the State of Design.
Under the Civil Aviation Safety Regulations 1998, the State of Registry, which in this case is Australia, bears the responsibility for ensuring the continuing airworthiness of individual aircraft registered within its jurisdiction. This obligation entails developing or adopting specific requirements that must be met to maintain the airworthiness of aircraft registered in Australia. Therefore, when CASA issues an Australian AD, such as AD/CONVAIR/24 in response to the United States FAA’s AD 87-17-10, it mandates the requirements of the State of Design for aircraft models 340 and 440 registered in Australia. This process ensures that Australian aircraft meet international safety standards and that the safety of air navigation is consistently upheld.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 must comply with the issued ADs. This includes aircraft operators, maintenance organisations, and other relevant stakeholders who must adhere to the requirements specified in the ADs to ensure their aircraft remain airworthy. Failure to comply with an AD can result in serious safety risks, potentially leading to aircraft being grounded or prohibited from operating until the necessary actions are taken to meet the AD requirements. CASA monitors compliance with ADs to ensure that all aircraft registered in Australia meet the required safety standards.
In the event of non-compliance with the provisions of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998, including failure to adhere to an AD, there can be significant consequences. The Act provides for both civil and criminal penalties for breaches, with the specific penalties depending on the nature and severity of the offence. For instance, under the Act, individuals or organisations found guilty of contravening an AD may face fines, imprisonment, or both. The maximum penalties can be substantial, reflecting the importance of maintaining high safety standards in the aviation industry. These legal repercussions underscore the critical nature of adhering to ADs and other regulatory requirements to ensure the safety of air navigation.
