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/BEA 109/2 affecting Beagle A109 (Airedale) series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/BEA 109/2. The cancellation will become effective on 30 July 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 is the foundational piece of legislation governing civil aviation in Australia. Enacted by the Commonwealth Parliament, the Act aims to ensure the safety and efficiency of air navigation, and it provides the legal framework for the regulation of aviation safety standards in Australia. Under section 98 of this Act, the Governor-General has the authority to make regulations that further the interests of air navigation safety, including the issuance of airworthiness directives (ADs). These ADs, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998, mandate specific actions to maintain the airworthiness of aircraft. The Civil Aviation Safety Authority (CASA), acting as Australia’s national airworthiness authority, issues these ADs to comply with the continuing airworthiness requirements stipulated by Annex 8 to the Convention on International Civil Aviation. This process ensures that aircraft registered in Australia meet international safety standards, reflecting the policy objective of maintaining high levels of aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, with such directives being considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. These ADs serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation, where the State of Design holds overall accountability for an aircraft type's airworthiness and must furnish necessary information to States of Registry. In the case of Australia, CASA, as the national airworthiness authority, is tasked with assessing any ADs issued by States of Design and, when necessary, issuing corresponding Australian ADs to enforce the required safety measures. For instance, CASA has cancelled Australian AD/BEA 109/2, which affected the Beagle A109 (Airedale) series aeroplanes, as the unsafe condition it was addressing no longer exists, thereby reflecting Australia’s commitment to international civil aviation standards. This regulatory action does not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations that safeguard air navigation safety. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legally binding and are considered legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are primarily centred around ensuring the continuing airworthiness of aircraft. The State of Design, which is the country where the aircraft is designed, holds the primary responsibility for the ongoing airworthiness of the aircraft type, including providing necessary information to the States of Registry. The State of Registry, which is the country where the aircraft is registered, must then develop or adopt requirements to ensure the aircraft’s continuing airworthiness. For aircraft on the Australian Register, CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the required safety measures.
Failure to comply with the airworthiness directives can result in significant consequences. While the specific penalties are not detailed in the provided text, non-compliance with such directives typically results in civil or criminal penalties. These could include fines, enforcement actions, or even criminal charges depending on the severity and intent behind the breach. The exact penalties would be dictated by relevant aviation safety and regulatory laws, which may vary depending on the circumstances and jurisdiction.
In summary, the key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for issuing and enforcing airworthiness directives to ensure the safety and airworthiness of aircraft. The obligations on the State of Design and the State of Registry are critical in maintaining these standards, and CASA plays a pivotal role in ensuring that Australian-registered aircraft meet these safety requirements.
