CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 FAA has issued AD 2005-03-01 affecting Boeing Model 747 aircraft. USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/325, which will become effective on 14 April 2005.
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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, 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 the legal framework for civil aviation safety and regulation. The Act aims to ensure the safety and efficiency of civil aviation within Australia and to meet international standards and obligations. One of the mechanisms through which this is achieved is the issuance of airworthiness directives (ADs). ADs are regulatory instruments that mandate the maintenance, repair, or alteration of aircraft to ensure continuing airworthiness, in accordance with the requirements set forth under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are crucial in maintaining the safety standards expected by the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and State of Registry in ensuring aircraft safety. The Civil Aviation (Safety Authority) Act 1990 empowers the Civil Aviation Safety Authority (CASA) to issue ADs, thereby allowing Australia to uphold its international commitments and ensure the safety of its airspace.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) under the oversight of the Civil Aviation Safety Authority (CASA). The Act applies to entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and aviation authorities, to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific kinds of aircraft or aeronautical products. These directives are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are subject to the provisions of the Legislative Instruments Act 2003. The geographic reach of these regulations is national, extending to all civil aviation activities within Australia. There are no stated exclusions or exemptions in this context, as the primary focus is on maintaining the continuing airworthiness of aircraft in accordance with international standards, particularly those set by the International Civil Aviation Organization (ICAO). While the Act provides the overarching authority, further details and specific requirements may be outlined in subordinate instruments issued by CASA.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to create regulations that serve the safety of air navigation. These regulations are further specified in the Civil Aviation Safety Regulations 1998. For instance, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and hence, an AD is considered a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
Under the Civil Aviation Regulations 1998, CASA has the authority to issue airworthiness directives to ensure the continuing airworthiness of aircraft types registered in Australia. This responsibility is rooted in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. The State of Registry, in this case CASA, must adopt requirements to ensure the continuing airworthiness of aircraft. When the State of Design issues an AD, CASA assesses the information and, if necessary, issues an Australian AD to enforce the requirements of the State of Design.
In practical terms, if the Federal Aviation Administration (FAA) issues an AD affecting a type of aircraft registered in Australia, such as the Boeing Model 747, CASA evaluates the AD. If the AD is deemed necessary, CASA issues an Australian AD, such as AD/B747/325, which becomes effective on a specified date. Given that this AD is a response to international obligations under the Convention on International Civil Aviation, there is no requirement for public consultation in Australia. Additionally, the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
Breaching the requirements of an AD can lead to significant legal consequences. While the Act does not explicitly outline specific offences or penalties for non-compliance with ADs, general aviation regulations and safety standards are strictly enforced. Non-compliance with ADs can result in the grounding of the aircraft, fines, and potential criminal charges for operators who fail to adhere to mandatory safety directives. CASA has the authority to take enforcement actions against non-compliant aircraft or operators, which can include revocation of airworthiness certificates and other regulatory penalties.
