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-2007-12 affecting Bell 230 series helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 222/42 which will become effective on 25 October 2007.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia with a focus on safety, efficiency, and the orderly development of air transport. This Act provides the legislative framework under which the Civil Aviation Safety Regulations 1998 were developed, aiming to ensure the continuing airworthiness of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations in the interest of air navigation safety. The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products. These directives are legislative instruments that must be assessed and potentially implemented by CASA to comply with international obligations under the Convention on International Civil Aviation, ensuring that Australia meets its responsibilities as a State of Registry. The policy objective is to maintain and enhance the safety standards of civil aviation in alignment with international best practices.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides a framework for the regulation of airworthiness directives (ADs) in Australia, thereby ensuring the safety of air navigation. Under the Act, the Governor-General has the authority to make regulations for the purposes of the Act, and these regulations can include the issuance of ADs by the Civil Aviation Safety Authority (CASA) for specified types of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs must align with international obligations, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design is responsible for the continuing airworthiness of aircraft types and must provide necessary information to ensure such airworthiness. As Australia’s national airworthiness authority, CASA must assess any ADs issued by the State of Design and, if deemed appropriate, issue corresponding Australian ADs to mandate the requirements domestically. This process does not require public consultation, as it is driven by international obligations and the specific need to address identified safety issues.
Key Provisions
The Civil Aviation Act 1988, through section 98, allows the Governor-General to create regulations aimed at ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulation ensures that ADs are considered legislative instruments under the Legislative Instruments Act 2003, and they are subject to disallowance as per section 46A of the Acts Interpretation Act 1901. These ADs are vital for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as outlined in Annex 8 of the Convention on International Civil Aviation.
The obligations imposed by these provisions primarily rest on CASA as Australia's national airworthiness authority. CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements stipulated by the original AD. This ensures that Australian-registered aircraft meet international safety standards. CASA's role also includes ensuring that any ADs issued under the Civil Aviation Safety Regulations 1998 are in line with Australia's obligations under international aviation conventions. Given the complexity and technical nature of these directives, CASA has the authority to issue them without public consultation, as determined by the Office of Best Practice Regulation, which has also ruled that ADs do not require a Regulatory Impact Statement.
The Civil Aviation Safety Regulations 1998 outline several consequences for breaches of ADs. Firstly, non-compliance with an AD can result in severe civil and criminal penalties. For instance, if an operator fails to comply with an AD, CASA can issue a Notice of Unauthorized Operation (NOUO), which can lead to the grounding of the aircraft in question. Under section 90 of the Civil Aviation Act 1988, individuals or corporations found guilty of contravening an AD can face fines and imprisonment. The specific penalties can vary but often include substantial fines and up to two years in prison for individual offenders, and greater penalties for corporate offenders. These stringent measures underscore the importance of adhering to ADs for maintaining aviation safety.
