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 issued AD 009-02-2000, affecting BAe 146 model aircraft, in March 2000. The UK is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to incorporate a new revision to the related Service Bulletin. The amended AD, AD/BAe 146/66 Amendment 3, will become effective on 1 September 2005. 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes 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 was enacted to provide a comprehensive legislative framework for the regulation of civil aviation in Australia, addressing the need for safety and efficiency in air navigation. This legislation empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, which includes the issuance of airworthiness directives (ADs). The ADs are critical for maintaining the continuing airworthiness of aircraft types registered in Australia, aligning with international standards as stipulated under Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further operationalise this by allowing the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft or aeronautical products, which are classified as legislative instruments under the Legislative Instruments Act 2003. The policy objective of this regulatory approach is to ensure that aircraft registered in Australia meet the highest safety standards, both domestically and internationally, by synchronizing Australian requirements with those of the aircraft's State of Design.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives, which are considered legislative instruments, are integral to ensuring the continuing airworthiness of aircraft and are issued in accordance with international standards set forth by the International Civil Aviation Organization (ICAO). The State of Design holds primary responsibility for an aircraft type's airworthiness and must provide necessary information to the State of Registry, which is obligated to develop or adopt requirements to ensure the aircraft's ongoing airworthiness. CASA, acting as Australia's national airworthiness authority, must evaluate information from the State of Design and, when appropriate, issue corresponding Australian ADs to enforce the requirements. This legislative framework ensures that Australian aircraft comply with international safety standards and that ADs are issued in response to directives from the relevant State of Design, often without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for ensuring the safety and airworthiness of aircraft operating in Australia. Specifically, 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 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments, as stipulated in subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. In the context of international aviation, the State of Design, such as the UK in the case of BAe 146 model aircraft, holds the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to appropriate States of Registry. Australia, as a State of Registry, is obligated to ensure the continuing airworthiness of registered aircraft, and CASA, acting as the national airworthiness authority, must issue Australian ADs in response to directives from the State of Design.
The obligations imposed by these regulations on parties and entities include the responsibility of CASA to review and, if necessary, issue Australian ADs in response to ADs issued by the State of Design. For example, following the issuance of UK CAA AD 009-02-2000, CASA amended the corresponding Australian AD to incorporate a new revision to the related Service Bulletin. This process is critical to maintaining the safety and airworthiness standards of aircraft registered in Australia. The State of Registry must also ensure that all aircraft operators comply with the ADs issued, which may include conducting necessary inspections, repairs, or modifications to aircraft to meet the specified airworthiness requirements. Additionally, aircraft manufacturers and operators must be diligent in adhering to the ADs, ensuring that their aircraft meet the requisite safety standards.
Breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly the requirements set forth in the ADs, can result in significant consequences. Non-compliance with an AD can lead to severe penalties, both civil and criminal. Civil penalties may include fines and the possibility of grounding aircraft that do not meet the required airworthiness standards. Criminal penalties can be imposed in more serious cases, where non-compliance is deemed to have endangered the safety of air navigation. The exact penalties depend on the nature and severity of the breach, but they can include substantial fines and imprisonment for individuals found guilty of serious violations. The enforcement of these regulations is vital to maintaining the high safety standards required in the aviation industry.
