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.
CASA issued AD/MSR/19 affecting Aerospatiale Rallye model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes 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 safety and efficiency in the industry. One of the mechanisms established by the Act is the ability for the Governor-General to make regulations that serve the interests of air navigation safety. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This legislative framework responds to the international 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 individual aircraft. CASA, acting as Australia’s national airworthiness authority, must therefore evaluate and, where necessary, issue ADs to ensure compliance with safety standards. This process ensures that Australian aviation maintains high safety standards in line with international protocols.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to the issuance of airworthiness directives (ADs) as instruments to ensure the safety of air navigation. Specifically, under the Act, the Governor-General can make regulations, and under the Regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for particular types of aircraft or aeronautical products. ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these ADs aligns with international standards set by the International Civil Aviation Organization (ICAO) and involves the responsibility of the State of Design for continuing airworthiness, as well as the State of Registry for individual aircraft. In this context, CASA acts on behalf of Australia’s national airworthiness authority, ensuring compliance with international mandates and local safety requirements.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for ensuring the safety of air navigation, including the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interest of safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue ADs for specific types of aircraft or aeronautical products. These directives, which are legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003, are a critical tool for maintaining airworthiness in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, must review and, if necessary, issue Australian ADs to implement the requirements of the State of Design. This ensures that Australian-registered aircraft meet the necessary safety standards. The process involves CASA assessing information from the State of Design and, if appropriate, issuing an Australian AD to mandate compliance with safety requirements.
There are specific obligations and requirements imposed on parties and entities governed by the Act. The State of Design must provide necessary information to ensure the continuing airworthiness of aircraft types. The State of Registry must develop or adopt requirements to ensure the airworthiness of individual aircraft. CASA, on behalf of Australia, must assess and implement ADs issued by the State of Design. The Manager, Airframes in the Airworthiness Engineering Branch, is responsible for making ADs in accordance with subsection 84A(2) of the Act. Failure to comply with these obligations can lead to serious safety issues and potential liabilities.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 also establish consequences for breaches of airworthiness requirements. While specific penalties are not detailed in the text, non-compliance with ADs can result in severe civil or criminal consequences. For instance, operating an aircraft that does not meet airworthiness standards can lead to fines, imprisonment, or both. Additionally, CASA can take enforcement actions such as grounding aircraft or imposing other restrictions to ensure compliance with safety regulations. It is crucial for all parties involved to adhere to these requirements to maintain the high safety standards expected in civil aviation.
