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 US FAA has issued AD 2008-05-05 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/317, which will become effective on 8 April 2008.
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, 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 address the need for comprehensive legislation governing the safety and regulation of civil aviation within Australia. This Act was brought into effect to ensure the safety of air navigation and to provide a legislative framework for the Australian Civil Aviation Authority (CASA) to exercise its regulatory functions. The Act empowers the Governor-General to make regulations in the interest of air navigation safety, with a particular focus on ensuring the continuing airworthiness of aircraft. In line with this objective, the Civil Aviation Safety Regulations 1998 were established, which among other things, allow CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as mandated under section 98 of the Civil Aviation Act 1988. These directives are crucial for maintaining safety standards in accordance with international obligations under the Convention on International Civil Aviation. The ADs are considered legislative instruments, subject to disallowance and review as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for the regulation of airworthiness directives (ADs) in Australia, ensuring safety in air navigation as mandated under section 98 of the Act. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, as outlined in subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901. Such directives are essential for the continuing airworthiness of aircraft, aligning with the responsibilities of the State of Design and the State of Registry as prescribed under Annex 8 of the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is mandated to assess information from the State of Design and issue corresponding Australian ADs when necessary. For instance, in response to the US Federal Aviation Administration's AD 2008-05-05 for Boeing B737 model aircraft, CASA issued AD/B737/317, which became effective on 8 April 2008. This process is conducted without public consultation, as the ADs are a direct response to international obligations and the issuing of ADs by the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. This legal basis allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998 for specific kinds of aircraft or aeronautical products. Such ADs serve as a critical mechanism for maintaining the continuing airworthiness of aircraft types and products, ensuring that they meet safety standards set forth by the regulatory framework.
The obligations imposed by these regulations primarily fall on CASA, which must assess any relevant ADs issued by the State of Design and, where necessary, issue corresponding Australian ADs to enforce these requirements on aircraft registered in Australia. This obligation ensures that the State of Registry adheres to international standards set by the Convention on International Civil Aviation, particularly those outlined in Annex 8, which places the responsibility for continuing airworthiness on the State of Design. For instance, when the US Federal Aviation Administration (FAA) issues an AD for a Boeing B737 model, CASA must evaluate this directive and, if appropriate, issue a corresponding Australian AD to ensure compliance.
Failure to comply with these ADs can lead to significant consequences. While specific penalties are not detailed in the text, the general legal framework suggests that non-compliance could result in civil or criminal penalties. Such penalties might include fines or imprisonment, depending on the severity of the breach and the specific provisions of the Civil Aviation Act and associated regulations. The seriousness of these potential penalties underscores the importance of adhering to ADs to maintain the safety and airworthiness of aircraft operating within Australian airspace.
Moreover, because ADs are considered legislative instruments under the Legislative Instruments Act 2003, they carry the authority of law and are subject to disallowance procedures as outlined in the Acts Interpretation Act 1901. This legislative status ensures that ADs are issued and enforced within a robust legal framework, providing a clear mandate for CASA to act in the interest of aviation safety. The absence of a Regulatory Impact Statement and public consultation reflects the urgent and critical nature of these directives, which are issued in response to international obligations and the immediate need to address safety issues identified by the State of Design.
