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 has issued AD 2006-12-11 affecting Boeing 737 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/289, which will become effective on 3 August 2006.
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, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes a regulatory framework aimed at ensuring the safety and efficiency of civil aviation in Australia. 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 is detailed in the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as a legislative instrument under the Acts Interpretation Act 1901, designed to maintain the continuing airworthiness of aircraft in accordance with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia's national airworthiness authority, is tasked with issuing these directives when necessary, ensuring compliance with the obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, through the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This regulatory mechanism is integral to maintaining safety standards in air navigation, as mandated by the Act. These ADs serve as legislative instruments, and they are issued in response to international obligations under the Convention on International Civil Aviation, specifically Annex 8, which outlines the responsibility of the State of Design for the continuing airworthiness of aircraft types. In Australia, CASA acts as the national airworthiness authority, tasked with ensuring that aircraft registered in Australia meet these international safety standards. When a State of Design, such as the United States for Boeing 737 series aircraft, issues an AD, CASA evaluates the directive and, if deemed necessary, issues a corresponding Australian AD to enforce the required safety measures. This process ensures that Australian-registered aircraft comply with international safety protocols, thereby safeguarding public safety in air travel.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together facilitate the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, section 98 of the Act allows the Governor-General to make regulations for safety, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for certain aircraft or aeronautical products (sections 98, 39.001). According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus are legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs are a critical tool for maintaining the continuing airworthiness of aircraft, aligning with Annex 8 of the Convention on International Civil Aviation.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose specific duties on the parties involved. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to the State of Registry to ensure the aircraft's continuing airworthiness (Annex 8). The State of Registry, in this case CASA, must then assess this information and issue an Australian AD if deemed necessary. This process is mandated by the international convention and ensures that Australian aircraft comply with international safety standards. CASA, as the national airworthiness authority, is obligated to evaluate ADs issued by the State of Design and subsequently issue Australian ADs to mandate the necessary safety requirements.
Failure to comply with ADs can result in significant consequences. While specific offences and penalties for non-compliance are not detailed in the provided text, it is clear that non-compliance with ADs can lead to severe civil or criminal penalties. Given the critical nature of airworthiness directives in ensuring the safety of air navigation, breaches can potentially result in the grounding of aircraft, legal action, and financial penalties. Although the maximum penalties are not specified in the text, the seriousness of non-compliance with such safety regulations underscores the importance of adhering to ADs.
