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 UK CAA has issued AD 05-08-98 affecting BAe Jetstream 4100 model aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/J4100/7, which will become effective on 20 February 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, enacted by the Australian Parliament, governs various aspects of civil aviation in Australia, including the safety and airworthiness of aircraft. This Act facilitates the regulation of air navigation safety and allows the Governor-General to make regulations for these purposes. The Civil Aviation Safety Regulations 1998, which were made under the authority of the Act, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs serve as a means to ensure the continuing airworthiness of aircraft types, aligning with international standards set by the International Civil Aviation Organization (ICAO). In accordance with the Legislative Instruments Act 2003, ADs are considered legislative instruments, and their issuance does not require public consultation or a Regulatory Impact Statement when issued in response to international obligations or directives from the State of Design.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These ADs, which are legislative instruments, are critical for ensuring the continuing airworthiness of aircraft and aeronautical products within Australia and are mandated by Australia’s obligations under the Convention on International Civil Aviation. The State of Design, responsible for the overall airworthiness of a specific aircraft type, issues initial ADs, and CASA, as Australia’s national airworthiness authority, assesses these directives and, if appropriate, issues Australian ADs to enforce the necessary requirements. The ADs are issued by CASA on behalf of the Australian Government and apply to all relevant aircraft and aeronautical products within Australia, ensuring compliance with international safety standards. The process of issuing these directives does not involve public consultation as it is driven by international obligations and the need to maintain safety standards, and it is deemed not to require a Regulatory Impact Statement.
Key Provisions
The key sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) as a means of ensuring the safety of air navigation. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. Subregulation 39.001(5) further classifies ADs as disallowable instruments under the Acts Interpretation Act 1901 and as legislative instruments under the Legislative Instruments Act 2003.
The obligations imposed by the Act and Regulations centre on the responsibilities of ensuring the continuing airworthiness of aircraft. The State of Design, in this case, the UK, has the primary responsibility for providing necessary information to ensure the airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, must assess the information provided by the State of Design and, if necessary, issue an Australian AD to enforce the requirements. The State of Registry of an individual aircraft, which is Australia in this context, must develop or adopt requirements to ensure the continuing airworthiness of aircraft on the Australian Register. This collaborative approach ensures that international safety standards are upheld and appropriately implemented within Australia.
Breaches of airworthiness directives can lead to significant civil and criminal consequences. While the specific provisions of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 do not detail specific offences or penalties within this excerpt, the general framework of the Act implies that non-compliance with ADs could result in enforcement actions by CASA. Such actions might include fines, suspension or revocation of aircraft certificates, or other regulatory sanctions. The severity of these penalties could vary depending on the nature and extent of the non-compliance, but the overarching goal is to ensure that airworthiness standards are strictly adhered to for the safety of air navigation.
