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 Civil Aviation Safety Authority or its predecessors issued AD/RAD/37 affecting Narco Nav VHF receivers. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/37. The cancellation will become effective on 9 April 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Systems and New Technologies, 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 provide a legislative framework for the regulation of civil aviation in Australia, with the overarching objective of ensuring the safety and efficiency of air navigation. Section 98 of the Act grants the Governor-General the authority to make regulations that serve the interests of air navigation safety, including the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998 further define the regulatory mechanisms through which these directives are implemented, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue such directives for specific types of aircraft or aeronautical products. This legislative structure ensures that CASA, as Australia’s national airworthiness authority, can mandate safety requirements in alignment with international standards, as stipulated under Annex 8 of the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, encompasses a broad range of entities and activities related to civil aviation within Australia, including the issuance of airworthiness directives (ADs). These regulations empower the Civil Aviation Safety Authority (CASA), the national airworthiness authority of Australia, to issue ADs for particular types of aircraft or aeronautical products to ensure the safety of air navigation. Such ADs are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve to maintain the continuing airworthiness of aircraft as stipulated by the Convention on International Civil Aviation, specifically Annex 8, which places the responsibility on the State of Design and the State of Registry to provide and implement necessary safety information. CASA, acting under these regulations, is required to assess and, if appropriate, issue Australian ADs in response to ADs issued by the State of Design to mandate the requirements for aircraft on the Australian Register. The geographic and jurisdictional reach of these regulations is national, affecting all entities involved in civil aviation within Australia. The Act and its subordinate regulations extend their application through the issuance of ADs and do not explicitly state exclusions or exemptions, though their implementation is guided by international conventions and agreements.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations necessary for the safety of air navigation. This includes the issuance of airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD is a legislative instrument, disallowable under section 46A of the Acts Interpretation Act 1901, as per subregulation 39.001(5). These directives are pivotal for maintaining the continuing airworthiness of aircraft types and aeronautical products, and they are issued by the Civil Aviation Safety Authority (CASA) in accordance with Annex 8 of the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft was designed, is responsible for the continuing airworthiness of an aircraft type, and must provide necessary information to ensure this airworthiness. Conversely, the State of Registry, which is the country where the aircraft is registered, must implement requirements to ensure the continuing airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and, if appropriate, issue an Australian AD to enforce the requirements.
The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA to assess any AD issued by a State of Design for aircraft on the Australian Register and to issue an Australian AD if necessary. This ensures that the continuing airworthiness of aircraft is maintained according to international standards. The cancellation of AD/RAD/37 affecting Narco Nav VHF receivers by CASA exemplifies this process, as it was cancelled on 9 April 2009 because the unsafe condition it addressed no longer existed. As this cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation, no public consultation was required, and no Regulatory Impact Statement was deemed necessary by the Office of Best Practice Regulation. The AD was issued by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
The Civil Aviation Safety Regulations 1998 also include provisions for the enforcement of airworthiness directives. Failure to comply with an AD can result in severe consequences, including the grounding of aircraft and legal penalties. Under section 11 of the Civil Aviation Act 1988, CASA can take enforcement action against any person who does not comply with an AD. This can include fines, imprisonment, or both. The maximum penalties for non-compliance with an AD can be substantial, reflecting the critical importance of air safety. Additionally, any person who knowingly contravenes an AD may face criminal charges, which can result in significant fines and imprisonment terms as prescribed by the Act. The regulations underscore the importance of adhering to ADs to ensure the safety and airworthiness of aircraft, with strict enforcement mechanisms in place to address any breaches.
