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 or its predecessors issued AD/AA-1/18 affecting Gulfstream AA-1 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-1/18. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, 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 regulate civil aviation and ensure the safety of air navigation, empowers the Governor-General to make regulations in the interests of safety. Under this authority, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 also specify that ADs are disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. This regulatory framework is aligned with Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of aircraft types and mandates information sharing with States of Registry. CASA, as Australia’s national airworthiness authority, must evaluate and, if necessary, issue Australian ADs in response to ADs from the State of Design, ensuring compliance with international standards and obligations.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 establish a framework for the regulation of airworthiness, including the issuance of airworthiness directives (ADs). Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular kinds of aircraft or aeronautical products to ensure the continuing airworthiness of aircraft registered in Australia. These directives are legislative instruments and must comply with the Legislative Instruments Act 2003. The ADs are typically issued in response to the obligations of the State of Design under Annex 8 to the Convention on International Civil Aviation, which places responsibility on the State of Design for the continuing airworthiness of an aircraft type. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and issue corresponding ADs if necessary. The scope of the ADs extends to all entities and persons involved in the maintenance, operation, and oversight of affected aircraft within Australia. While the ADs are issued in accordance with international obligations, they do not require consultation with the Australian public or a Regulatory Impact Statement as per the Office of Best Practice Regulation. The issuance and cancellation of ADs, such as AD/AA-1/18 for Gulfstream AA-1 model aircraft, are managed by CASA, reflecting the dynamic nature of airworthiness regulation in response to evolving safety concerns and international standards.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to enact regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are legislative instruments in accordance with the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are multifaceted. The State of Design holds primary responsibility for ensuring the continuing airworthiness of an aircraft type, as outlined in Annex 8 of the Convention on International Civil Aviation. This includes providing necessary information to the States of Registry to maintain airworthiness. The State of Registry must then develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess this information and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design.
Breaching the requirements set forth in an AD can result in significant consequences. Non-compliance with an AD can lead to the grounding of an aircraft, as the AD outlines specific safety measures that must be adhered to. Under section 84A(3) of the Civil Aviation Act 1988, any person who contravenes an AD may be liable for civil or criminal penalties. The specific penalties depend on the nature and severity of the breach but can include fines and imprisonment. The maximum penalties for breaches are set out in section 84A(4) of the Act, which can vary based on the specific contraventions involved.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for ensuring the safety and airworthiness of aircraft through the issuance of ADs. These regulations impose significant obligations on both the State of Design and the State of Registry, as well as on CASA, to maintain high safety standards. The consequences for non-compliance with these directives are serious, encompassing both civil and criminal penalties.
