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 United States FAA issued AD 2008-26-06 affecting Rolls Royce Corporation AE3007A series engines. The United States is the State of Design for this engine series. CASA has amended the equivalent Australian AD to AD/AE 3007/6 Amendment 1 which will become effective on 12 March 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 Regulatory Review 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 was enacted to provide a comprehensive legislative framework for civil aviation in Australia, ensuring safety, efficiency, and orderly development. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. One such regulation, regulation 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These ADs are critical in maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The authority to issue such ADs stems from the overarching responsibility of the State of Design for continuing airworthiness and the duty of the State of Registry to ensure the safety of individual aircraft. This legislative instrument was introduced to address the need for harmonised international standards and effective national regulation to ensure the safety of air navigation in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products, thereby ensuring compliance with safety standards. These directives are legislative instruments under the Legislative Instruments Act 2003 and serve to maintain the continuing airworthiness of aircraft registered in Australia, in line with international obligations under the Convention on International Civil Aviation. The application of these ADs extends to all aircraft and aeronautical products within the Australian jurisdiction, with CASA mandated to assess and, where necessary, issue Australian ADs in response to directives from the State of Design, such as the United States for the Rolls Royce Corporation AE3007A series engines. These regulations do not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and the imperative to swiftly address safety concerns. The issuance of such directives underscores the responsibility of both the State of Design and the State of Registry to ensure the safety of air navigation.
Key Provisions
The Civil Aviation (Safety) Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority is exercised under section 98 of the Civil Aviation Act 1988, with the aim of ensuring the safety of air navigation. Each AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and, as such, constitutes a legislative instrument as per section 6 of the Legislative Instruments Act 2003. The issuing of these directives is further aligned with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design bears responsibility for the ongoing airworthiness of aircraft types and must provide necessary information to ensure this for the appropriate States of Registry.
The obligations imposed by these regulations are multifaceted. The State of Design must issue ADs to ensure the continuing airworthiness of aircraft types, while the State of Registry—which in Australia is CASA—must assess this information and, if necessary, issue a corresponding Australian AD to enforce the State of Design’s requirements. This process ensures that all aircraft registered in Australia meet the safety standards dictated by the State of Design. Additionally, the ADs must be issued in response to international standards and conventions, as seen with the recent amendment to the Australian AD for Rolls Royce Corporation AE3007A series engines, following the issuance of AD 2008-26-06 by the United States Federal Aviation Administration.
Given the international nature of aviation safety, non-compliance with these ADs can have serious consequences. The ADs are designed to mandate specific actions or modifications to aircraft to prevent safety hazards. While the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement and no public consultation is mandated, failure to comply with these directives can result in severe penalties. These may include civil or criminal sanctions, reflecting the high stakes involved in ensuring the safety of air navigation. The maximum penalties for such breaches are significant, underscoring the critical nature of adhering to the ADs issued by CASA.
The legislative framework is designed to ensure that all stakeholders—including aircraft manufacturers, operators, and regulatory authorities—are aligned in their efforts to maintain the highest standards of aviation safety. CASA’s role in issuing and enforcing ADs is central to this process, ensuring that all aircraft operating in Australian airspace meet the necessary safety standards. The rigorous process for issuing these directives reflects the importance of international cooperation and adherence to global aviation safety standards.
