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 269/26 Amendment 16 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/16 Amendment 16. 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 Australian Parliament, serves as the primary legislative framework for regulating civil aviation in Australia, with the overarching goal of ensuring the safety of air navigation. One of its key provisions allows the Governor-General to make regulations under section 98, thereby facilitating the creation of safety standards. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions by empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft and aeronautical products, as stipulated under regulation 39.001. These ADs, which are legislative instruments as per the Legislative Instruments Act 2003, are essential for maintaining the continuing airworthiness of aircraft as per international standards set by the Convention on International Civil Aviation. In line with these international obligations, CASA has the responsibility to assess and, if necessary, issue Australian ADs based on directives from the State of Design, ensuring compliance with safety requirements.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to make regulations that contribute to 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 ADs for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and review as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, respectively. The ADs are integral to the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which requires States of Design to provide necessary information to ensure the airworthiness of aircraft types registered in other states, including Australia. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and issue Australian ADs when necessary, ensuring compliance with international standards and obligations. The process is rigorous and ensures that Australian-registered aircraft meet stringent safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for ensuring the safety of air navigation, with specific focus on airworthiness directives (ADs). Under section 98 of the Act, the Governor-General is empowered to create regulations that support the Act, particularly those related to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in subregulation 39.001(5) and further elaborated in the Legislative Instruments Act 2003. The ADs serve as a key mechanism for maintaining the continuing airworthiness of aircraft, a responsibility that lies with the State of Design, as per Annex 8 to the Convention on International Civil Aviation.
The obligations placed on parties under these regulations are significant. The State of Design has the overarching responsibility to provide all necessary information to ensure the continuing airworthiness of a type of aircraft, which must then be assessed and acted upon by the State of Registry, in this case CASA. When an AD is issued by the State of Design, CASA must evaluate this information and, if necessary, issue a corresponding Australian AD to enforce the requirements. This process ensures that Australian-registered aircraft meet the safety standards set forth by international conventions. The most recent example involves the Schweizer (Hughes) 269 series helicopters, where CASA issued and subsequently cancelled an AD due to the resolution of the unsafe condition.
Failure to comply with the requirements set out in ADs can result in severe consequences. The Civil Aviation Act 1988 does not explicitly detail the penalties for non-compliance with ADs, but non-compliance can lead to significant civil and criminal liabilities. Civil penalties can include fines, while criminal penalties can include imprisonment. The seriousness of these consequences underscores the importance of adhering to the ADs issued by CASA. The regulatory process, as illustrated by the cancellation of AD/HU 269/26 Amendment 16, demonstrates the rigorous measures taken to ensure that Australian aviation remains compliant with international safety standards.
