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 2008-10-07 affecting Boeing 747 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B747/379, which will become effective on 3 July 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, 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 is a foundational piece of Australian legislation that provides the regulatory framework for civil aviation in the country. Enacted to address the need for comprehensive safety and regulatory standards within the aviation sector, the Act empowers the Governor-General to make regulations that ensure the safety of air navigation. In particular, the Act grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in the Civil Aviation Safety Regulations 1998. The overarching aim of the Act is to uphold the highest standards of safety and airworthiness in line with international conventions, particularly those set forth by the International Civil Aviation Organization (ICAO). This legislative instrument is integral to Australia's compliance with global aviation safety standards, ensuring that the nation's aviation industry adheres to internationally recognised practices and requirements.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, as made under section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring compliance with safety regulations. Regulation 39.001 of these regulations specifically allows CASA to mandate requirements for maintaining the airworthiness of aircraft in Australia. An AD is considered a legislative instrument under subregulation 39.001(5) and the Acts Interpretation Act 1901, subject to disallowance under section 46A. These directives are integral to the continuing airworthiness of aircraft as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds primary responsibility for an aircraft type’s airworthiness. In Australia, CASA, as the national airworthiness authority, must evaluate ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce these requirements on aircraft registered within Australia. This regulatory framework ensures that Australian aircraft meet international safety standards, although no public consultation is required for ADs issued in response to international obligations.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, as applied to the issue of airworthiness directives (ADs), include sections 98 and 84A. Section 98 allows the Governor-General to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. Section 84A pertains to the process of issuing legislative instruments, which includes ADs. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specified kinds of aircraft or aeronautical products. The ADs are designed to ensure that the aircraft remain in a safe condition for operation and must be complied with by the relevant parties.
The obligations and requirements imposed by this legislation on the parties it governs are substantial. The State of Design, which is responsible for the continuing airworthiness of a particular aircraft type, must provide all necessary information to ensure the safety and airworthiness of the aircraft. This includes issuing ADs to address any identified safety issues. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. CASA, as Australia’s national airworthiness authority, must assess any foreign ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to ensure compliance with international safety standards. The operators of affected aircraft must adhere to these ADs to maintain the airworthiness of their aircraft.
The Act also outlines the consequences for non-compliance with ADs. Any breach of an AD can lead to severe civil and criminal penalties. While the specific penalties are not detailed in the text, it is clear that the enforcement of ADs is critical for maintaining aviation safety. Non-compliance could result in significant financial penalties and potential criminal charges for individuals or companies responsible for the oversight of the aircraft. The issuance of ADs under this legislation is a regulatory tool to ensure that all stakeholders, including aircraft manufacturers, operators, and regulatory authorities, are aligned in their efforts to maintain the highest standards of aviation safety.
