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 2008-0127 affecting SAAB AB SF340A and 340B model aircraft. The EASA acts on behalf of Sweden, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/SF340/107, 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, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation within Australia, ensuring the safety and efficiency of the nation's aviation industry. It grants the Governor-General the authority to make regulations, including the issuance of airworthiness directives (ADs), under section 98 to maintain the safety of air navigation. The Act aims to ensure that all civil aviation activities in Australia comply with international standards, particularly those set by the International Civil Aviation Organization (ICAO). In this context, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft and aeronautical products, ensuring they meet safety standards.
This legislative framework is designed to address the need for harmonised international aviation safety standards and to mandate CASA's role in issuing ADs in response to directives from States of Design or other relevant authorities. By issuing AD/SF340/107 in response to EASA's AD 2008-0127, CASA ensures that Australian operators of SAAB AB SF340A and 340B aircraft comply with necessary safety measures, reflecting Australia's commitment to international aviation safety protocols. The AD process is streamlined to avoid unnecessary public consultation, as it is directly tied to international obligations and specific safety concerns identified by the State of Design.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives apply to the types of aircraft or aeronautical products specified within the regulations and are a legislative instrument under the Legislative Instruments Act 2003. The ADs are essential for ensuring the continuing airworthiness of aircraft, aligning with the responsibilities of the State of Registry and State of Design as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is responsible for assessing and issuing these directives when necessary, thereby ensuring compliance with international standards and obligations. The issuance of an AD, such as the Australian AD/SF340/107 for the SAAB AB SF340A and 340B model aircraft, is made in accordance with the Civil Aviation Act 1988, without the requirement for public consultation or a Regulatory Impact Statement, reflecting its alignment with international agreements and obligations.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 set out the framework for the issuance of airworthiness directives (ADs) in Australia, as stipulated in section 98 of the Act and regulation 39.001 of the Regulations. ADs are legislative instruments that the Civil Aviation Safety Authority (CASA) can issue to ensure the continuing airworthiness of specific types of aircraft or aeronautical products. These directives are essential for maintaining safety standards in air navigation and are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design overall responsibility for the airworthiness of aircraft types and mandates the provision of necessary information to States of Registry.
The obligations under this Act and the Regulations primarily fall on CASA, as the national airworthiness authority. When an AD is issued by the State of Design, such as the European Aviation Safety Authority (EASA) for the SAAB AB SF340A and 340B model aircraft, CASA must evaluate the directive and, if necessary, issue an Australian AD to implement the requirements outlined by the State of Design. This ensures that the aircraft registered in Australia comply with international safety standards. The State of Registry, in this case, Australia, must also develop or adopt requirements to maintain the continuing airworthiness of aircraft, ensuring they meet the mandated safety standards set forth in the ADs.
The Act and the Regulations do not specify particular offences, penalties, or consequences for non-compliance with ADs. However, the failure to adhere to an AD can lead to significant safety risks and potential legal consequences, as ADs are critical for maintaining the airworthiness of aircraft. CASA has the authority to enforce compliance through various means, including audits, inspections, and legal action against operators who fail to comply with the directives. Non-compliance can result in severe penalties, including fines and the grounding of aircraft, ultimately impacting the safety and operations of the aviation industry.
CASA's issuance of an AD, such as the Australian AD/SF340/107 for the SAAB AB SF340A and 340B models, is conducted under the authority granted by section 84A(2) of the Civil Aviation Act 1988. Given that these ADs are issued in response to international obligations and the directives of the State of Design, there is no requirement for public consultation or the preparation of a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This streamlined process ensures that ADs are issued promptly to address safety issues without unnecessary delays.
