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 2008-0120 affecting Eurocopter AS355 model helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian
AD/AS 355/98, which will become effective on 28 August 2008.
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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 is pivotal legislation in Australia, enacted to ensure the safety and efficiency of civil aviation within the country. This Act empowers the Governor-General to create regulations conducive to air navigation safety, thereby enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) as stipulated in the Civil Aviation Safety Regulations 1998. These directives are crucial in maintaining the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia's national airworthiness authority, plays a vital role in evaluating and issuing ADs in response to directives from the State of Design, ensuring compliance with ICAO's Annex 8 and other international obligations. This regulatory framework underscores the importance of international cooperation in maintaining aviation safety standards, with CASA acting on behalf of Australia in the global aviation community.
Scope and Application
The Civil Aviation Act 1988 applies to various entities within the aviation sector, including aircraft operators, manufacturers, and maintenance providers, as well as individuals such as pilots and air traffic controllers. The Act's provisions govern the safety and regulation of civil aviation in Australia, impacting the conduct and transactions related to aircraft operations and air navigation. The Civil Aviation Safety Regulations 1998 further specify the requirements for airworthiness and operational safety, extending the reach of the Act to ensure compliance with international standards. Airworthiness directives (ADs) issued under regulation 39.001 of these Regulations are considered legislative instruments and apply to specific types or models of aircraft registered in Australia. These ADs mandate actions necessary to maintain airworthiness and are issued in response to safety concerns identified by the State of Design or under Australia's obligations under the Convention on International Civil Aviation. Notably, ADs do not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and urgency.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Governor-General to issue regulations in the interest of air navigation safety (section 98). Regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft or aeronautical products, and these directives are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 (subregulation 39.001(5)). This classification makes them legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations of the parties governed by these provisions are substantial. The State of Design, such as France for the Eurocopter AS355 model helicopters, has the primary responsibility for ensuring the continuing airworthiness of an aircraft type, and must provide necessary information to the States of Registry, like Australia. The State of Registry, represented by CASA in Australia, must develop or adopt requirements to ensure the airworthiness of individual aircraft within its jurisdiction. When an AD is issued by the State of Design, CASA must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures alignment with international standards and the Convention on International Civil Aviation.
Failure to comply with the requirements set out in these ADs can lead to serious consequences. The Civil Aviation Safety Regulations 1998 do not specify explicit penalties for non-compliance with ADs, but non-compliance with CASA regulations can result in enforcement actions such as fines, suspension, or revocation of airworthiness certificates. These actions can lead to significant operational disruptions and potential safety risks. Furthermore, civil or criminal liabilities may arise if non-compliance results in accidents or incidents, with penalties varying depending on the severity and circumstances of the breach.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the safety of air navigation through the issuance and enforcement of airworthiness directives. These regulations impose significant responsibilities on both the State of Design and the State of Registry, with CASA acting as the national airworthiness authority in Australia. Non-compliance with these directives can lead to severe enforcement actions and potential civil or criminal liabilities.
