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
The Civil Aviation Safety Authority or its predecessors issued AD/DHC-2/16 affecting De Havilland DHC-2 (Beaver) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-2/16. The cancellation will become effective on 23 October 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 framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation and the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations for these purposes, thereby enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) as stipulated in the Civil Aviation Safety Regulations 1998. The ADs, as legislative instruments, are crucial for maintaining the safety standards of aircraft and aeronautical products, aligning with Australia’s obligations under the Convention on International Civil Aviation. The cancellation of a specific AD, such as AD/DHC-2/16 for De Havilland DHC-2 (Beaver) model aeroplanes, demonstrates CASA's commitment to safety by addressing and rectifying any identified unsafe conditions, thereby ensuring compliance with international aviation standards without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation, with a particular focus on the airworthiness of aircraft and aeronautical products. Regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are intended to ensure the continuing airworthiness of these items. These ADs are legislative instruments that must comply with the Legislative Instruments Act 2003. The application of these directives is in line with the obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types and the State of Registry as responsible for the airworthiness of individual aircraft. This legislative framework applies to all aircraft and aeronautical products within Australia and is aimed at maintaining the highest standards of safety in air navigation. The application of these regulations extends to all relevant entities, including aircraft manufacturers, operators, and maintenance providers, ensuring that all persons and industries involved in civil aviation adhere to the specified safety requirements.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance and management of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations in the interests of air navigation safety. Regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products, ensuring compliance with safety standards. Section 39.001(5) of the Regulations further classifies ADs as disallowable instruments under the Acts Interpretation Act 1901, meaning they are subject to parliamentary scrutiny.
The obligations imposed by these provisions require CASA to act in accordance with international standards set by the Convention on International Civil Aviation, particularly under Annex 8, which mandates the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types. The State of Registry is responsible for ensuring the ongoing airworthiness of individual aircraft, developing or adopting the necessary requirements to maintain safety standards. The Civil Aviation Safety Authority, as the enforcing body, must issue ADs when unsafe conditions are identified and ensure these directives are adhered to by aircraft operators.
In terms of potential consequences, breaches of ADs may lead to enforcement actions by CASA. Non-compliance with ADs can result in significant safety risks, potentially leading to grounding of the affected aircraft until the required actions are taken. While the specific Civil Aviation Safety Regulations 1998 do not outline explicit civil or criminal penalties for non-compliance with ADs, CASA can impose administrative penalties, including fines, as well as take legal action against individuals or companies that fail to comply with safety directives. The maximum penalties for such breaches can vary, but they are designed to ensure compliance and uphold the highest safety standards in civil aviation.
