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 80-13-14, affecting Cessna 310R model aircraft, in 1980. The United States is the State of Design for this type. As a result of a request from the Senate Standing Committee on Rules and Ordnances, CASA has amended the equivalent Australian AD to correct a typographical error. The amended AD, AD/CESSNA 310/58 Amendment 1, will become effective on 28 August 2008. 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 Best Practice Regulation 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 Branch, 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, with a strong emphasis on safety and international compliance. This Act empowers the Governor-General to create regulations, such as airworthiness directives (ADs), that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 further detail the mechanisms by which ADs can be issued, and these regulations are designed to ensure the continuing airworthiness of aircraft types. The problem or gap this legislation addresses is the need for a regulatory framework that ensures aircraft safety and compliance with international standards, particularly in the context of continuing airworthiness. The Act is overseen by the Australian Parliament, and the policy objective is to maintain the highest safety standards in civil aviation through stringent regulatory measures.
The issuing of airworthiness directives falls under the authority of the Civil Aviation Safety Authority (CASA), Australia's national airworthiness authority, which is mandated to enforce regulations that comply with the Convention on International Civil Aviation. When a State of Design, such as the United States, issues an AD affecting a type of aircraft registered in Australia, CASA is obligated to review and, if necessary, issue a corresponding AD to mandate those requirements domestically. This process ensures that Australian-registered aircraft meet international safety standards and that the public is protected by consistent and rigorous regulatory oversight. The ADs are considered legislative instruments and are issued without public consultation due to their international obligations and the nature of the regulatory process.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are made in accordance with section 84A(2) of the Civil Aviation Act 1988. ADs serve as a crucial means of ensuring the continuing airworthiness of aircraft and are issued in alignment with the responsibilities of the State of Design and the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs to enforce the requirements of foreign ADs, ensuring compliance with international standards. For instance, CASA amended the Australian AD for the Cessna 310R model aircraft in response to an AD issued by the United States Federal Aviation Administration, correcting a typographical error and ensuring that the Australian AD aligns with the international directive. These regulations apply to all aircraft registered in Australia and are issued without public consultation, as they are necessitated by international obligations and the specific requirements of aircraft design and registry states.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, outlines the framework within which airworthiness directives (ADs) are issued and managed in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that ensure the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. An AD is a legislative instrument under section 6 of the Legislative Instruments Act 2003, and it is a critical tool for maintaining the continuing airworthiness of aircraft as per Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and the Regulations are significant for both CASA and the States of Registry. CASA, as Australia’s national airworthiness authority, must assess any AD issued by a State of Design and, if deemed necessary, issue an equivalent Australian AD. This process ensures that Australian aircraft meet the continuing airworthiness standards set forth by international agreements. The State of Registry of an individual aircraft must develop or adopt requirements to ensure the continuing airworthiness of that aircraft, ensuring compliance with both domestic and international standards.
Failure to comply with an AD can result in severe consequences. The Act provides for civil and criminal penalties for breaches. Civil penalties can include fines, and in severe cases, criminal penalties can result in imprisonment. The exact penalties are determined by the severity of the breach and the specific provisions of the Act and Regulations. These provisions are designed to ensure that all parties involved in the aviation industry adhere to the stringent safety standards necessary to protect the public and maintain the integrity of air navigation systems.
