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/DHA-3/27 affecting De Havilland DHA-3 (Drover) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHA-3/27. The cancellation will become effective on 20 November 2008. 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 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, with a strong emphasis on safety. It empowers the Governor-General to make regulations that serve the interests of safe air navigation, thereby ensuring the integrity of Australia's civil aviation system. The Civil Aviation Safety Regulations 1998, made under section 98 of the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to maintain the safety standards of aircraft and aeronautical products. These ADs are legislative instruments subject to disallowance and must comply with the Legislative Instruments Act 2003. The process for issuing and cancelling ADs is driven by the need to uphold Australia's obligations under the Convention on International Civil Aviation, particularly the responsibilities of the State of Design and State of Registry concerning the continuing airworthiness of aircraft. The cancellation of an AD, such as the one affecting De Havilland DHA-3 (Drover) model aeroplanes, is a direct response to the resolution of an unsafe condition, and no public consultation or Regulatory Impact Statement is required in such cases.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These regulations apply to entities involved in the aviation industry, including aircraft manufacturers, operators, and maintenance providers, as well as individuals such as pilots and engineers. Geographically, the application of these regulations extends nationally within Australia, reflecting the Commonwealth's jurisdiction over civil aviation. The issuance of ADs is subject to international obligations under the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and the State of Registry for continuing airworthiness. While ADs are legislative instruments that can be disallowed under certain conditions, they do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The Manager, Airframe and Structures, within CASA’s Airworthiness Engineering Group, has the authority to issue these directives in accordance with the Act, ensuring compliance with both national and international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This legislative framework is designed to maintain the safety standards of aircraft operating within Australian airspace. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is classified as a legislative instrument according to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations require CASA to act on ADs issued by the State of Design, which holds overall responsibility for the continuing airworthiness of an aircraft type. The State of Registry, in this case CASA, must ensure that the necessary requirements to maintain airworthiness are developed or adopted. When a State of Design issues an AD, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements. This process ensures that the safety and airworthiness of aircraft registered in Australia are maintained in line with international standards as outlined in Annex 8 to the Convention on International Civil Aviation.
Breach of the obligations outlined in the Civil Aviation Safety Regulations 1998 can result in significant consequences. While specific penalties are not detailed within the text provided, non-compliance with ADs can lead to severe civil or criminal consequences. The safety and regulatory framework established by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are designed to prevent accidents and ensure that all parties adhere to stringent safety standards. Failure to comply with these regulations can result in enforcement actions by CASA, which may include fines, revocation of airworthiness certificates, or other punitive measures designed to uphold the high safety standards required in civil aviation.
