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 Emergency AD 2009-0012-E affecting Airbus A330 series aircraft. The EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A330/95, Amendment 2, which will become effective on 18 January 2009. 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 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, enacted to ensure the safety and efficiency of civil aviation in Australia, provides the framework under which the Civil Aviation Safety Regulations 1998 operate. One critical aspect of these regulations is the issuance of airworthiness directives, which are legislative instruments designed to ensure that aircraft and aeronautical products meet safety standards. The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue such directives, aligning with the obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design holds responsibility for the continuing airworthiness of an aircraft type. When a State of Design, such as France for the Airbus A330 series, issues an airworthiness directive, CASA, as Australia’s national airworthiness authority, is required to evaluate this information and issue a corresponding Australian AD if necessary. This process ensures that Australian aircraft meet international safety standards, reflecting the policy objective of maintaining the highest level of safety in civil aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation in Australia. Under these regulations, CASA is empowered to issue ADs for specific kinds of aircraft or aeronautical products to maintain or restore airworthiness. An AD is a legislative instrument that can be disallowed under the Acts Interpretation Act 1901, and it operates under the broader international obligation of Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds primary responsibility for the continuing airworthiness of aircraft types and must provide necessary information to States of Registry. In the case of Australian-registered aircraft, CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce these safety requirements. For instance, following the issuance of an Emergency AD by the European Aviation Safety Agency (EASA) concerning Airbus A330 series aircraft, CASA has issued its own AD to address the same safety concerns for aircraft registered in Australia. This process ensures compliance with international standards and obligations, and it is conducted without public consultation as ADs do not require a Regulatory Impact Statement. The ADs are issued by the Manager, Systems and New Technologies within CASA's Airworthiness Engineering Group, as per the provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance of airworthiness directives (ADs), which are legislative instruments designed to ensure the safety of aircraft in air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. Essentially, these provisions enable CASA to mandate safety requirements for aircraft types registered in Australia, aligning with international standards set by the International Civil Aviation Organization (ICAO).
The obligations placed on CASA under this legislative framework are significant. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA is mandated to assess this information. If appropriate, CASA must issue an Australian AD to enforce the requirements specified by the State of Design. This obligation ensures that Australian aircraft meet international safety standards and are maintained in a state of continuing airworthiness. The State of Registry, which in this case is Australia, is also responsible for ensuring the continuing airworthiness of aircraft registered within its jurisdiction. Therefore, CASA must act promptly and decisively in reviewing, approving, and issuing ADs to maintain safety standards.
Failure to comply with an AD can lead to severe legal consequences. The Civil Aviation Act 1988 and associated regulations impose strict requirements on aircraft operators, manufacturers, and other relevant parties to adhere to ADs. Non-compliance can result in both civil and criminal penalties. For instance, failure to adhere to an AD may lead to the grounding of an aircraft, and in more severe cases, could result in prosecution under the Act. The maximum penalties for such offences can include substantial fines and, in some instances, imprisonment. These measures underscore the importance of adhering to ADs to ensure the highest safety standards in civil aviation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for the issuance and enforcement of airworthiness directives. CASA’s role in assessing and issuing ADs is critical in ensuring that aircraft registered in Australia meet international safety standards. The obligations on aircraft operators and other parties to comply with these directives are stringent, with significant penalties for non-compliance, reinforcing the importance of adhering to these safety measures.
