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.
Transport Canada has issued AD CF-2009-32 affecting Bell Helicopter Textron Canada 430 series helicopters. Canada is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/BELL 430/14, which will become effective on 14 August 2009.
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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, provides a legal framework for ensuring the safety and regulation of civil aviation in Australia. This Act was enacted to address the need for comprehensive oversight and regulation of airworthiness, safety, and security within the civil aviation sector. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations necessary 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 certain types of aircraft or aeronautical products. These directives are legislative instruments that play a crucial role in maintaining the continuing airworthiness of aircraft, as mandated by international standards under the Convention on International Civil Aviation. CASA issues these directives to ensure compliance with international obligations and to maintain the safety standards required for Australian-registered aircraft.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation, with specific focus on the issuance of airworthiness directives (ADs) for aircraft and aeronautical products. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs serve as legislative instruments, subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft, a responsibility that falls both on the State of Design and the State of Registry under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, must issue Australian ADs when a State of Design issues relevant directives, ensuring compliance with international safety standards. This process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The ADs are issued by CASA under the authority of the Civil Aviation Act 1988, specifically by the Manager, Future Technology and Regulatory Trends, within the Standards Development and Future Technology Division.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, as referenced in regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products (39.001(1)). An AD is a legislative instrument, which means it is subject to disallowance and scrutiny under the Legislative Instruments Act 2003 (39.001(5)). The primary purpose of an AD is to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. When CASA issues an AD, it does so based on the requirements and information provided by the State of Design, and it must be assessed to ensure it meets the necessary safety standards for Australian conditions.
The obligations imposed by these regulations on CASA and the State of Registry are significant. CASA must evaluate the ADs issued by the State of Design, such as Transport Canada's AD CF-2009-32 for the Bell Helicopter Textron Canada 430 series helicopters, to determine if they need to be adapted or implemented as Australian ADs (AD/BELL 430/14). The State of Registry, which in this case is Australia, must ensure that the aircraft on its register comply with the continuing airworthiness requirements stipulated by these directives. This includes implementing the ADs in a timely manner and ensuring all necessary actions are taken to maintain the safety standards of the aircraft in question.
Any breach of the regulations governing ADs could result in serious consequences. While specific offences and penalties are not detailed in the provided text, non-compliance with ADs could potentially lead to significant civil or criminal liabilities under the broader framework of the Civil Aviation Act 1988. Given the critical nature of airworthiness directives, failure to adhere to these requirements could compromise the safety of air navigation, potentially resulting in severe penalties or legal action against the responsible parties. The maximum penalties for such breaches would depend on the specific provisions of the Civil Aviation Act and other relevant legislation, but they could include substantial fines or imprisonment for serious infractions.
