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 United States Federal Aviation Administration issued AD 2005-25-09 affecting Pratt and Whitney PW4000 series engines. The United States is the State of Design for these engine types. In response CASA issued AD/PW4000/11 Amdt 1. In addition FAA AD 2005-25-09 superseded previous ADs including FAA AD 99-08-15 which was referenced in AD/PW4000/6. As a result AD/PW4000/6 is no longer required as the unsafe condition is addressed by AD/PW4000/11 Amdt 1. The cancellation of AD/PW4000/6 will become effective on 11 January 2010.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. The Office of Regulatory Review 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, enacted by the Australian Parliament, addresses the need for comprehensive regulation of civil aviation within Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to create regulations, such as the Civil Aviation Safety Regulations 1998, that pertain to the safety of air navigation. Under this legislative framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are critical in maintaining the continuing airworthiness of aircraft as mandated by international conventions, including Annex 8 to the Convention on International Civil Aviation. This legislative mechanism ensures that CASA, as Australia’s national airworthiness authority, can mandate safety requirements when necessary, often in response to directives issued by the aircraft's State of Design. The enactment of such regulations is aimed at upholding the highest safety standards in civil aviation, aligning with international obligations and practices.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, applies to entities and individuals involved in civil aviation operations within Australia, including aircraft operators, manufacturers, and maintenance organisations. The Act and Regulations mandate adherence to airworthiness directives (ADs), which are legislative instruments issued by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products. These ADs are designed to address specific safety concerns and are informed by the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the primary responsibility for continuing airworthiness. CASA, as Australia’s national airworthiness authority, is required to assess and, if necessary, issue Australian ADs in response to ADs issued by the States of Design to ensure compliance with international safety standards. The ADs apply to all aircraft registered in Australia and are critical in maintaining the safety of air navigation. The issuance and cancellation of these directives are conducted under the authority granted by the Act and the Regulations, without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, particularly section 98, allow the Governor-General to create regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These regulations underscore the importance of maintaining airworthiness standards to ensure the safety of aircraft in Australian airspace.
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, imposes specific obligations on various parties to ensure the ongoing airworthiness of aircraft. The State of Design, typically the country where the aircraft is designed, is responsible for providing necessary information to ensure continuing airworthiness, as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is required to assess information from the State of Design and, if necessary, issue Australian ADs to enforce the mandated requirements. The State of Registry, which is the country where the aircraft is registered, must develop or adopt measures to ensure the continuing airworthiness of aircraft. These obligations ensure that all stakeholders, including designers, manufacturers, and regulatory bodies, collaborate to maintain high safety standards.
Breaches of the Civil Aviation Act 1988 and the associated regulations can lead to significant legal consequences. While the specific offences and penalties are not detailed in the provided text, it is clear that failing to comply with airworthiness directives can result in severe repercussions. Civil penalties could include fines, while criminal penalties might involve imprisonment, reflecting the seriousness of ensuring air safety. Additionally, non-compliance can result in the grounding of aircraft, which would have substantial operational and financial implications for airlines and other aviation stakeholders. The stringent requirements and potential penalties underscore the importance of adhering to the regulations set forth by CASA and the obligations under international conventions.
