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 F-1997-144-038 R1 affecting Eurocopter SA341 and SA342 model helicopters. France is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/GAZELLE/20, Amendment 1, which will become effective on 16 March 2006. This AD cancels and replaces the previous issue.
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 was enacted to establish and regulate civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. This Act empowers the Governor-General to create regulations that are essential for maintaining the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, specifically allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as a mechanism for the State of Registry to ensure the continuing airworthiness of aircraft registered within Australia, aligning with international standards under Annex 8 of the Convention on International Civil Aviation. The policy objective is to harmonise national regulations with international obligations to maintain high safety standards in civil aviation.
The issuance of ADs, such as the one for Eurocopter SA341 and SA342 model helicopters, reflects Australia's commitment to international standards and the necessity to respond to directives from the State of Design. CASA, acting as Australia’s national airworthiness authority, assesses and issues these directives to ensure compliance with international obligations without the need for public consultation. This process is overseen by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, in accordance with the legislative framework provided by the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, which are subsidiary legislation under the Civil Aviation Act 1988, establish the framework for issuing airworthiness directives (ADs) in Australia. These regulations apply to any person or entity involved in the design, manufacture, maintenance, or operation of aircraft and aeronautical products within Australia. The geographic reach of these regulations is national, as they govern activities across the Commonwealth of Australia. They also extend to international obligations under the Convention on International Civil Aviation, ensuring that Australian standards align with global safety requirements. The ADs issued under these regulations are legislative instruments that mandate compliance with specific safety standards, and they are designed to ensure the continuing airworthiness of aircraft registered in Australia. Although ADs are issued in response to international obligations and do not require public consultation or a Regulatory Impact Statement, they are meticulously assessed by the Civil Aviation Safety Authority (CASA) to ensure they meet national and international safety standards.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative framework is designed to ensure the safety of air navigation, aligning with section 98 of the Civil Aviation Act 1988. A key provision is subregulation 39.001(5), which classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and subsequently, as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003. These ADs are instrumental in maintaining the continuing airworthiness of aircraft, a responsibility that is primarily the purview of the State of Design under Annex 8 of the Convention on International Civil Aviation.
The obligations imposed by these regulations are significant. The State of Design, such as France in the case of Eurocopter SA341 and SA342 model helicopters, must issue ADs to ensure the continuing airworthiness of the aircraft types they design. This is a critical step, as these ADs provide necessary information to the States of Registry, such as Australia, to maintain airworthiness. CASA, acting as Australia's national airworthiness authority, has the duty to assess the information provided by the State of Design and, if necessary, issue corresponding Australian ADs. This ensures that Australian regulations are harmonised with international standards and practices.
Failure to comply with these ADs can lead to serious consequences. Although the specific penalties for non-compliance are not detailed in the provided text, it is reasonable to infer that violations could result in civil or criminal penalties, as is common in regulatory frameworks designed to ensure public safety. The seriousness of these potential penalties underscores the importance of adhering to the airworthiness directives issued under the Civil Aviation Safety Regulations 1998. The legislative process, as outlined, also ensures that these directives are issued with due consideration of international obligations and standards, further emphasising the critical role they play in maintaining the safety of air navigation.
