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.
State of Design ADs issued on or after 1 October 2009 are defined as ADs per Civil Aviation Safety Regulations Part 39.001A.
CASA issued AD/DAUPHIN/71 Amdt 1 affecting Eurocopter SA 360 and SA 365 series helicopters. The EASA issued AD 2010-0014 on 26 January 2010 which supersedes the requirements of AD/DAUPHIN/71 Amdt 1 and as such this AD has been cancelled. The EASA acts on behalf of France which is the state of design for these helicopters. The cancellation will become effective on 9 February 2010.
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, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation and to provide a framework for regulating civil aviation in Australia. The Act empowers the Governor-General to make regulations, which include the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives serve to maintain the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The objective of the Act is to promote the safety of air navigation, ensuring that aircraft are maintained in a safe and airworthy condition. As part of its role, CASA assesses airworthiness directives issued by the State of Design and may issue corresponding directives for aircraft registered in Australia, thus fulfilling its mandate under the Act. The Act's provisions and the subsequent regulations underscore the importance of stringent safety measures and the collaborative efforts between various states to uphold these standards.
Scope and Application
The Civil Aviation Act 1988, as amended, grants the Governor-General the authority to create regulations that promote 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 specified types of aircraft or aeronautical products. These ADs, which are legislative instruments, serve as a means to ensure the ongoing airworthiness of aircraft, in line with Annex 8 of the Convention on International Civil Aviation. The State of Design, typically the country where an aircraft type is designed, holds the primary responsibility for the continuing airworthiness of that type and must furnish necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, evaluates this information and issues Australian ADs when required. The ADs are applicable to the specific aircraft or aeronautical products they target, ensuring compliance with safety standards.
The application of these regulations is geographically focused on Australia, with CASA acting on behalf of the Australian government to enforce airworthiness directives. Any exclusions or exemptions from these regulations are not explicitly detailed in the provided text, though the nature of ADs suggests they are highly targeted and specific to the safety needs of particular aircraft types. The application of ADs is also influenced by international agreements and the responsibilities of the State of Design and the State of Registry, which ensures a coordinated approach to aircraft safety on a global scale. The ADs issued by CASA are subject to cancellation or amendment when superseded by equivalent directives from other jurisdictions, as demonstrated by the cancellation of AD/DAUPHIN/71 Amdt 1 due to the issuance of EASA AD 2010-0014.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act, the Governor-General is empowered to create regulations to safeguard air navigation, and regulation 39.001 of the Regulations permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument, making it a legislative instrument under the Legislative Instruments Act 2003.
These airworthiness directives are critical in maintaining the safety and airworthiness of aircraft. The State of Design, which is the country where the aircraft type is designed, has the primary responsibility for the continuing airworthiness of the aircraft type. This responsibility includes providing necessary information to ensure airworthiness to the State of Registry, which is the country where the individual aircraft is registered. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the required safety measures. This regulatory process ensures that Australian-registered aircraft meet international safety standards.
Compliance with these ADs is mandatory for all parties governed by the Civil Aviation Safety Regulations. Operators of affected aircraft must adhere to the specified maintenance and operational requirements outlined in the ADs to ensure that their aircraft remain airworthy. Failure to comply with an AD can result in serious safety risks and legal consequences. CASA has the authority to take enforcement actions against non-compliance, which may include fines and other penalties. The maximum penalties for breaches of ADs can be substantial, reflecting the critical nature of air safety regulations.
While issuing an AD, CASA is not required to consult with the Australian public, as determined by the Office of Best Practice Regulation. Furthermore, ADs do not necessitate a Regulatory Impact Statement. The ADs are developed and issued by authorised personnel within CASA, such as the Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, in accordance with section 94(1) of the Act. This ensures that ADs are issued by qualified individuals who understand the implications and requirements of airworthiness directives.
