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 European Aviation Safety Authority (EASA) has issued AD 2008-0010R1 affecting Airbus A330 series aircraft. The EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A330/84, Amendment 1, which will become effective on 17 October 2008. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting 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 comprehensive legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation and the regulation of aircraft. It empowers the Governor-General to make regulations for air navigation safety, including the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are issued by the Civil Aviation Safety Authority (CASA) in response to international obligations and requirements set forth in the Convention on International Civil Aviation. The objective of these regulations is to harmonise Australia's aviation safety standards with those of other ICAO Contracting States, particularly in ensuring that aircraft types registered in Australia meet international safety standards. Given the nature of ADs, which are typically issued in response to specific safety concerns raised by the State of Design, no public consultation is required, and they do not necessitate a Regulatory Impact Statement. The AD in question, AD/A330/84, Amendment 1, issued by CASA in response to an AD from the European Aviation Safety Authority affecting Airbus A330 series aircraft, exemplifies this regulatory approach.
Scope and Application
The Civil Aviation Act 1988, as amended and implemented through the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia, which are legislative instruments designed to ensure the safety and airworthiness of aircraft. Regulation 39.001 of these regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs concerning specific types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the responsibility to the State of Design to provide necessary information for airworthiness. In Australia, CASA, acting as the national airworthiness authority, must assess and implement these directives when issued by the relevant State of Design, such as the European Aviation Safety Authority for Airbus A330 series aircraft. The ADs are issued under the authority of the Governor-General and are not subject to public consultation or a Regulatory Impact Statement, reflecting their urgent nature and the reliance on international safety standards.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, authorises the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. These directives are regulatory instruments that pertain to specific types of aircraft or aeronautical products, aimed at ensuring the safety of air navigation. Pursuant to subregulation 39.001(5), ADs are classified as disallowable instruments under the Acts Interpretation Act 1901, and therefore, as legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The Civil Aviation Safety Regulations 1998 impose obligations on the Civil Aviation Safety Authority (CASA) to assess ADs issued by the State of Design—the country where the aircraft was originally designed—and to issue corresponding Australian ADs when necessary. This ensures that the continuing airworthiness of aircraft registered in Australia complies with international standards. The State of Registry, which is Australia in this context, must develop or adopt requirements to maintain the airworthiness of aircraft. The process requires CASA to evaluate ADs from the State of Design, such as the European Aviation Safety Authority's AD 2008-0010R1 affecting Airbus A330 series aircraft, and subsequently issue Australian AD/A330/84, Amendment 1, effective from 17 October 2008.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are required to adhere to the provisions of ADs, which may include mandatory modifications, inspections, or operational restrictions on aircraft to mitigate safety risks. These regulations ensure that aircraft remain airworthy throughout their operational life by enforcing compliance with updated safety standards and requirements. Operators must implement the mandated changes or face potential legal consequences for non-compliance.
Failure to comply with an AD can result in significant legal repercussions. Civil penalties may include fines up to $66,000 for individuals and $330,000 for corporations, as stipulated under regulation 17.003 of the Civil Aviation Safety Regulations 1998. Additionally, CASA can take enforcement actions such as grounding non-compliant aircraft, which could lead to operational disruptions and financial losses for operators. Criminal penalties may also apply if the non-compliance results in serious safety incidents or breaches that endanger public safety.
