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 issued AD/GENERAL/55 amendment 2 in 2000. CASA has assessed this AD and as a result has cancelled Australian AD/GENERAL/55 amendment 2. The cancellation will become effective on 25 October 2007. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled thereby reducing the regulatory load on Australian operators no consultation with the Australian public has taken place. 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 regulate civil aviation in Australia, ensuring the safety and efficiency of air navigation, among other objectives. The Act provides the legal framework under which the Civil Aviation Safety Regulations 1998 were also established. One of the significant aspects of this regulatory framework is the issuance of airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft and aeronautical products. This is achieved through regulation 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue such directives. The Civil Aviation Safety Regulations 1998 also stipulate that ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The policy objective behind these regulations is to align with international standards set by the International Civil Aviation Organization (ICAO), particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and the State of Registry in maintaining the airworthiness of aircraft. The Civil Aviation Safety Authority, acting on behalf of the Australian government, plays a crucial role in assessing and, if necessary, issuing ADs to ensure compliance with these international standards.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, apply to entities and persons involved in civil aviation operations within Australia. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) which are legislative instruments that ensure the safety and airworthiness of aircraft. The ADs are typically issued by the State of Design of an aircraft type and mandate requirements for the continuing airworthiness of aircraft registered in Australia. CASA, as the national airworthiness authority, assesses the information from the State of Design and, if appropriate, issues corresponding Australian ADs. These directives cover various aspects of aircraft maintenance and operation, and their compliance is mandatory for all affected parties. The application of these regulations extends to all aircraft and aeronautical products registered in Australia, ensuring that safety standards are uniformly enforced across the country. While ADs are a significant regulatory tool, they are subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, as interpreted through the Civil Aviation Safety Regulations 1998, establish the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for aircraft or aeronautical products. Specifically, section 98 of the Act empowers the Governor-General to create regulations for air safety, while regulation 39.001 allows CASA to issue ADs for certain types of aircraft or aeronautical products. These ADs are formally recognised as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are considered legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations and requirements imposed by this Act and its associated regulations are primarily centred around ensuring the continuing airworthiness of aircraft. According to Annex 8 to the Convention on International Civil Aviation, the State of Design, which is responsible for the aircraft type, must provide necessary information to ensure airworthiness. The State of Registry, which is the country where the aircraft is registered, must adopt or develop requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft comply with international standards for air safety.
In the context of the AD/GENERAL/55 amendment 2 issued by CASA in 2000, the authority has assessed the directive and decided to cancel it, effective from 25 October 2007. The cancellation is due to the unsafe condition that the AD was addressing no longer existing, thus negating the need for a replacement AD. Since the cancellation reduces the regulatory load on Australian operators, there was no need for consultation with the Australian public. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, made the AD in accordance with subsection 84A(2) of the Act.
The legislation also outlines the consequences for breaches of the ADs. While the specific offences, penalties, or consequences for non-compliance are not detailed in the provided text, it is clear that adherence to ADs is critical for ensuring air safety. Failure to comply with an AD could result in severe civil or criminal penalties, reflecting the importance of the regulations in maintaining the safety of air navigation. CASA, as the enforcing body, would be responsible for taking action against non-compliance, which could include fines, grounding of aircraft, or other regulatory actions to ensure compliance and uphold safety standards.
