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 Civil Aviation Safety Authority or its predecessors issued AD/FU24/54 affecting Fletcher FU24-954 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/FU24/54. The cancellation will become effective on 7 May 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, addresses the safety and regulation of civil aviation within Australia. This legislation provides the legal framework for the Civil Aviation Safety Authority (CASA) to oversee the safety of air navigation and aircraft. One key aspect of this regulation is the issuance of airworthiness directives (ADs), which are legislative instruments designed to ensure that aircraft and aeronautical products meet the necessary safety standards. In line with international standards under the Convention on International Civil Aviation, the State of Design has the responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry is tasked with maintaining the airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs in response to international directives to safeguard the safety of aircraft registered in Australia. The AD/FU24/54 affecting Fletcher FU24-954 model aircraft, issued by CASA, was subsequently cancelled as the unsafe condition it addressed no longer existed, reflecting Australia's adherence to international civil aviation obligations.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) for aircraft and aeronautical products, with the overarching goal of ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, ensuring compliance with safety standards. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, and its issuance aligns with Australia's commitments under the Convention on International Civil Aviation, specifically Annex 8, which mandates the State of Design to maintain the continuing airworthiness of aircraft types. The State of Registry, in this case, CASA, is responsible for ensuring the continuing airworthiness of aircraft registered in Australia and must act on ADs issued by the State of Design. This regulatory framework applies to all aircraft registered in Australia and involves entities such as aircraft manufacturers, operators, and maintenance service providers. The scope of the Act and regulations is national, and they extend to all aircraft types and aeronautical products used in Australian airspace. There are no stated exclusions or exemptions in the issuance of ADs, and the regulations do not specify thresholds for their application, relying instead on the necessity to maintain airworthiness and safety.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are instrumental in maintaining the safety of air navigation, as outlined in section 98 of the Civil Aviation Act 1988. An AD is legally considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is also recognised as a legislative instrument under the Legislative Instruments Act 2003. This legislative framework ensures that ADs are formal and enforceable mechanisms for ensuring the continuing airworthiness of aircraft.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and other parties include the assessment and potential issuance of Australian ADs when a State of Design issues an AD against an aircraft type registered in Australia. The State of Design, typically the country where the aircraft was designed, is responsible for providing necessary information to ensure the continuing airworthiness of the aircraft type. Correspondingly, the State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. This includes reviewing ADs issued by the State of Design and determining whether an Australian AD is necessary.
Failing to comply with airworthiness directives can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD may result in civil penalties, including fines. The maximum penalty for contravening an AD can be substantial, reflecting the critical nature of these directives for aviation safety. Additionally, continued operation of an aircraft in violation of an AD may lead to enforcement actions by CASA, which could include grounding the aircraft or other regulatory measures to ensure compliance. These stringent measures underscore the importance of adhering to ADs to maintain the safety and airworthiness of aircraft.
