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 Italian authority (ENAC) has issued AD 1998-186 affecting Agusta AB412 model helicopters. Italy is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 412/49, which will become effective on 16 March 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, 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 Parliament of Australia, was introduced to provide a legislative framework for the regulation of civil aviation, with a strong emphasis on safety. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation. Complementing the Act, the Civil Aviation Safety Regulations 1998 were established to provide detailed safety standards and procedures, including the issuance of airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft and aeronautical products. These regulations mandate that the Civil Aviation Safety Authority (CASA) must issue ADs to address safety concerns identified by the State of Design, in this case, Italy for the Agusta AB412 model helicopters. The issuance of the Australian AD/BELL 412/49 follows CASA’s assessment of the Italian AD 1998-186 and is made in accordance with the Act’s provisions to uphold international obligations under the Convention on International Civil Aviation. The AD has been determined to not require a Regulatory Impact Statement, and no public consultation has taken place as it is a direct response to an AD from the State of Design.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for ensuring the safety of air navigation in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) which are legislative instruments designed to maintain the continuing airworthiness of aircraft and aeronautical products. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables CASA to issue ADs for certain types of aircraft or aeronautical products, and these ADs are subject to disallowance under the Acts Interpretation Act 1901. The scope of these directives applies to all aircraft registered in Australia, thereby affecting both operators and manufacturers within the aviation industry. Geographically, the application of these regulations is national, as CASA is the designated authority for ensuring compliance with international standards set by the Convention on International Civil Aviation. There are no stated exclusions or exemptions within the text provided, though the ADs themselves may contain specific exclusions or thresholds relevant to the aircraft types and products they govern. The ADs are also issued without public consultation, as they are responses to international obligations and assessments by the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia. Section 98 of the Act allows the Governor-General to make regulations for air 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. Section 39.001(5) clarifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and consequently, a legislative instrument under the Legislative Instruments Act 2003. This legislative foundation ensures that ADs have a legal basis and are enforceable within Australia.
Under these regulations, CASA is required to assess any ADs issued by the State of Design (the country where the aircraft is designed) and, if necessary, issue corresponding Australian ADs. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry (where the aircraft is registered) is responsible for the airworthiness of individual aircraft. This dual responsibility ensures that safety standards are consistently applied across different jurisdictions and that aircraft remain airworthy throughout their operational lives.
The obligations imposed by these provisions include the need for CASA to review and, if necessary, issue Australian ADs in response to ADs from other countries. CASA must ensure that these directives align with Australian standards and are effectively implemented. This process is critical to maintaining the safety and airworthiness of aircraft operating in Australia. Furthermore, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft, ensuring that all necessary measures are taken to keep aircraft safe and compliant with regulatory standards.
Failure to comply with ADs can result in severe civil and criminal penalties. Under section 14 of the Civil Aviation Act 1988, an operator who fails to comply with an AD can face penalties, including fines and imprisonment. The specific penalties can vary depending on the severity of the breach and the circumstances of the case. The regulations underscore the importance of adhering to ADs, as non-compliance not only endangers public safety but also subjects operators to significant legal consequences.
