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 369/4 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/4. The cancellation will become effective on 4 June 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 Australian Parliament, serves to regulate civil aviation within Australia to ensure the safety of air navigation. The Act empowers the Governor-General to create regulations under section 98, which are intended to uphold the safety standards necessary for air navigation. Among these regulations are the Civil Aviation Safety Regulations 1998, which enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as stipulated under regulation 39.001. The ADs, being legislative instruments, are subject to disallowance under section 46A of the Acts Interpretation Act 1901, and their creation follows the guidelines set out in the Legislative Instruments Act 2003. These directives are crucial in maintaining the continuing airworthiness of aircraft, in line with the obligations under Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design the responsibility for providing necessary information to the States of Registry to ensure the ongoing safety and airworthiness of aircraft types.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs) to ensure the safety of aircraft. Specifically, under section 98 of the Act, the Governor-General can make regulations for the purposes of the Act, which includes the issuance of ADs by the Civil Aviation Safety Authority (CASA) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments and are crucial for maintaining the continuing airworthiness of aircraft types. The State of Design is responsible for the airworthiness of an aircraft type, and Australia, as a State of Registry, must adhere to these directives and, where necessary, issue Australian ADs to enforce the requirements. The scope of this Act extends to all aircraft registered in Australia, and the regulations apply to entities such as aircraft manufacturers, operators, and maintenance providers. The geographic reach of this legislation is national, as it governs civil aviation within Australia, though it also aligns with international standards set by the Convention on International Civil Aviation. The Act does not require public consultation or a Regulatory Impact Statement for ADs, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation (s 98, reg 39.001). These directives are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 (s 46A) and the Legislative Instruments Act 2003 (s 6). An AD is a formal instruction issued by CASA to address safety issues with specific types of aircraft or aeronautical products, aligning with international standards under Annex 8 of the Convention on International Civil Aviation. The State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry must implement the necessary requirements for individual aircraft.
The obligations under the Act and Regulations require CASA to assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to maintain safety standards (Annex 8). For example, CASA assessed and subsequently cancelled Australian AD/HU 369/4 concerning McDonnell Douglas (Hughes) 369 series Helicopters, as the unsafe condition no longer existed. This action aligns with Australia's obligations under the Convention on International Civil Aviation, which necessitates that no consultation with the public was required for this cancellation. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The Manager Systems and New Technologies, in the Airworthiness Engineering Group, issued this AD on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The Act and Regulations also outline the consequences for non-compliance with ADs. Failure to comply with an AD can result in serious safety risks and may lead to enforcement actions against the aircraft operator. Under the Civil Aviation Act 1988, CASA has the authority to take action against non-compliant operators, which may include fines, suspension or revocation of an operator's certificate, and other administrative penalties. In severe cases, criminal charges may be brought against individuals responsible for non-compliance, leading to imprisonment. The exact penalties depend on the nature and severity of the breach, but they serve as a deterrent to ensure adherence to airworthiness directives and the maintenance of high safety standards in aviation.
