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 German LBA issued AD D-2004-352 R4 EASA reference 2005-2514, affecting Hoffmann aircraft Propellers in 2005. Germany is the State of Design for Hoffmann Propellers. As a result of a request from industry, CASA has amended the equivalent Australian AD to Amendment 3. The amended AD, AD/PHOF/2 Amendment 3, will become effective on 7 July 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 Section Head - Systems, 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, aims to ensure the safety of air navigation and provide a regulatory framework for civil aviation. The Act empowers the Governor-General to make regulations for these purposes, thereby facilitating the implementation of safety measures and standards. One significant regulation under this Act is the Civil Aviation Safety Regulations 1998, which among other provisions, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative instrument is integral to maintaining the continuing airworthiness of aircraft, aligning with international standards under Annex 8 to the Convention on International Civil Aviation, and ensuring that Australia meets its obligations as a Contracting State. The process of issuing ADs reflects a collaborative approach, where CASA, as the national airworthiness authority, responds to directives from the State of Design and mandates appropriate requirements for aircraft registered in Australia.
Scope and Application
The Civil Aviation Regulations 1998 under the Civil Aviation Act 1988 provide the framework for issuing airworthiness directives (ADs) that mandate safety measures and maintenance requirements for aircraft and aeronautical products registered in Australia. These directives apply to aircraft types and aeronautical products, targeting their continued airworthiness as mandated by the State of Design and enforced by the State of Registry, which, in Australia's case, is the Civil Aviation Safety Authority (CASA). This regulatory reach ensures compliance with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which outlines the continuing airworthiness obligations of the respective states. ADs are legislative instruments that CASA issues in response to directives from the State of Design, and they apply to all aircraft and aeronautical products within Australia's jurisdiction. While ADs are issued under the authority of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, they do not require public consultation or a Regulatory Impact Statement, as they are aligned with international obligations and designed to maintain safety standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for particular types of aircraft or aeronautical products. The ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003 and are subject to disallowance under section 46A of the Acts Interpretation Act 1901.
The Act and regulations impose significant obligations on CASA and other parties involved in the issuance and compliance with ADs. CASA, as Australia's national airworthiness authority, is required to assess information from the State of Design when it issues ADs and, if appropriate, issue corresponding Australian ADs to enforce the design state's requirements. This ensures that aircraft registered in Australia meet the necessary airworthiness standards. Additionally, the State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to ensure compliance with ADs. The State of Design, in this case Germany for Hoffmann Propellers, is responsible for issuing ADs for aircraft types it designs and must provide necessary information to States of Registry to ensure continuing airworthiness.
Failure to comply with ADs can result in severe consequences. The Civil Aviation Act 1988 and associated regulations may impose offences, penalties, and civil or criminal consequences for non-compliance. For example, operators who fail to adhere to ADs may face fines, imprisonment, or both, depending on the severity of the breach. The specific penalties are not detailed in the provided text, but they are likely to be severe given the importance of airworthiness for public safety. Furthermore, non-compliance with ADs can lead to the grounding of aircraft, which can have significant economic and operational impacts on the aviation industry.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for the issuance and enforcement of ADs in Australia. These regulations ensure that aircraft meet necessary safety standards by requiring CASA to issue corresponding ADs when prompted by the State of Design. The obligations imposed on CASA, States of Registry, and operators are critical for maintaining airworthiness, and non-compliance can result in significant penalties and operational disruptions.
