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/HU 269/77 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/77. 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, Airframe and Structures, 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, governs the regulation of civil aviation in Australia and is intended to ensure the safety of air navigation. This legislation provides the framework for the Civil Aviation Safety Regulations 1998, which detail the requirements for airworthiness directives (ADs). These regulations allow the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products to address safety issues. The ADs are legislative instruments subject to disallowance and are in line with international standards set by the International Civil Aviation Organization (ICAO). The policy objective of these regulations is to maintain the continuing airworthiness of aircraft in accordance with international obligations, ensuring that Australian authorities take appropriate actions when ADs are issued by States of Design. CASA’s role is to assess and, if necessary, mandate the requirements of these international ADs for aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, as amended, provides the legal framework for the regulation of civil aviation safety in Australia. Under section 98 of this Act, the Governor-General is empowered to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. The Civil Aviation Safety Regulations 1998, which are subordinate instruments under this Act, further delineate the responsibilities and processes for ensuring airworthiness. Regulation 39.001 of these regulations grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specified kinds of aircraft or aeronautical products. These ADs serve as legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are intended to mandate specific requirements to maintain the airworthiness of aircraft registered in Australia, in compliance with international standards set by the International Civil Aviation Organization (ICAO). The ADs are typically issued in response to identified safety issues and are a critical tool in ensuring that aircraft meet continuing airworthiness standards. The Act and its regulations apply nationally, extending Australia's responsibilities under international aviation agreements to ensure that all aircraft operating within its jurisdiction meet stringent safety standards.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, outline the process and authority for issuing airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the Act, which includes the issuance of ADs for ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the power to issue these ADs for specific kinds of aircraft or aeronautical products. Furthermore, under subregulation 39.001(5), ADs are classified as disallowable instruments, thereby making them subject to the scrutiny and requirements outlined in section 46A of the Acts Interpretation Act 1901. This classification also means that ADs are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to act as the national airworthiness authority for Australia. When an AD is issued by the State of Design, CASA must assess the information provided to determine its relevance and necessity for the Australian Register. This involves evaluating whether the AD should be adopted or adapted to create an Australian AD that enforces the same safety measures. The State of Registry also has the responsibility to ensure the continuing airworthiness of individual aircraft registered within its jurisdiction, which includes adhering to any relevant ADs.
The Act and associated regulations establish clear penalties and consequences for non-compliance with ADs. Under the Civil Aviation Act 1988, failure to comply with an airworthiness directive can result in severe civil or criminal consequences. Specifically, the Act may impose penalties for breaches, although the exact penalties are not detailed in the provided text. Additionally, the Convention on International Civil Aviation mandates that States of Design and States of Registry uphold stringent safety standards, and failure to meet these obligations can lead to further international repercussions.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for the issuance and enforcement of airworthiness directives, ensuring that the safety of air navigation is maintained. CASA’s role is pivotal in assessing and implementing these directives, thereby safeguarding the continuing airworthiness of aircraft registered in Australia. The consequences of non-compliance are significant, reinforcing the critical importance of adhering to these regulatory requirements.
