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 French DGAC has issued AD UF-2005-144 affecting AS 365 and SA 365 model helicopters. France is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DAUPHIN/81, which will become effective on 10 August 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, 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 Commonwealth Parliament, aims to ensure the safety and efficiency of civil aviation within Australia. This legislation establishes the framework for regulating the aviation industry, including the issuance of airworthiness directives (ADs) to maintain the safety standards of aircraft. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, with CASA being the national airworthiness authority responsible for implementing these regulations. The policy objective of the Act is to uphold the highest standards of safety in civil aviation, aligning with international conventions such as the Convention on International Civil Aviation, which places responsibility on the State of Design for the continuing airworthiness of aircraft types.
In line with these objectives, the Civil Aviation Safety Regulations 1998 provide CASA with the authority to issue ADs for specific aircraft or aeronautical products, ensuring that Australian regulations reflect international safety standards. The issuance of ADs is critical in maintaining the continuing airworthiness of aircraft registered in Australia, as it allows for the implementation of safety measures mandated by the State of Design. This process ensures that Australian aviation practices are consistent with international obligations and safety standards, thereby safeguarding the public and promoting efficient air navigation.
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, as per regulation 39.001. This regulatory framework ensures the safety of air navigation and mandates that ADs are issued in response to continuing airworthiness concerns identified by the State of Design or State of Registry. These directives serve as legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and regulated as per the Legislative Instruments Act 2003. The application of these directives extends to any aircraft registered within Australia, necessitating CASA to issue Australian ADs when corresponding foreign directives are applicable. For instance, following the issuance of an AD by the French Directorate General for Civil Aviation (DGAC) affecting AS 365 and SA 365 model helicopters, CASA issued Australian AD/DAUPHIN/81, effective from 10 August 2005. Given that these directives align with Australia's obligations under the Convention on International Civil Aviation, they do not require public consultation or a Regulatory Impact Statement. This legislative and regulatory structure ensures that all aircraft operating within Australia meet stringent safety standards, facilitating compliance with international aviation safety protocols.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act empowers the Governor-General to make regulations for the Act's purposes and in the interests of safety, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for 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, making them legislative instruments according to the Legislative Instruments Act 2003.
These regulations impose certain obligations on the parties involved. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure the safety of the aircraft, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is responsible for the individual aircraft's continuing airworthiness, must develop or adopt requirements to ensure the aircraft's airworthiness. CASA, as Australia's national airworthiness authority, must assess the ADs issued by the State of Design and, if appropriate, issue Australian ADs to mandate the requirements of the State of Design.
Failure to comply with ADs may result in civil and criminal consequences. The specific penalties are not detailed in the provided text, but the Act and Regulations imply that non-compliance could lead to significant legal ramifications. Given the critical nature of airworthiness directives, breaches may be subject to both civil penalties, such as fines, and criminal penalties, including imprisonment, depending on the severity and impact of the non-compliance.
In the specific case of AD/DAUPHIN/81 issued by CASA in response to French DGAC's AD UF-2005-144, no public consultation was necessary due to Australia's obligations under the Convention on International Civil Aviation. Additionally, the Office of Regulatory Review determined that ADs do not require a Regulatory Impact Statement, streamlining the process for issuing these critical safety measures. The AD was 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, ensuring that the directive follows due process and aligns with regulatory standards.
