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, the Civil Aviation Safety Authority (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 engine 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, including the continuing airworthiness of propellers installed in aircraft.
CASA or its predecessors issued AD/PR/13 affecting Dowty-Rotol propellers. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 19 November 2009. No replacement AD is required.
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, New Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia. This legislation aims to ensure the safety of air navigation and the continuing airworthiness of aircraft and aeronautical products. Under this Act, the Governor-General has the authority to make regulations in the interest of aviation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are designed to address potential safety issues with specific aircraft or aeronautical products. The ADs are legislative instruments, subject to disallowance, and must comply with international standards, particularly those set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further detail the process for issuing ADs and their regulatory status. This legislative framework underscores Australia's commitment to maintaining high safety standards in civil aviation, both domestically and in alignment with international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. This authority extends to mandating the necessary actions to maintain the airworthiness of these items, thereby ensuring compliance with safety standards. An AD is a legislative instrument, which means it carries the force of law and must adhere to the scrutiny and disallowance processes outlined in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of ADs is influenced by international obligations under the Convention on International Civil Aviation, specifically Annex 8, which assigns responsibility to the State of Design for the continuing airworthiness of engine types and to the State of Registry for the ongoing airworthiness of individual aircraft. This regulatory framework is designed to maintain a high standard of safety across the aviation sector, with CASA playing a pivotal role in its implementation within Australia. The cancellation of AD/PR/13 affecting Dowty-Rotol propellers, as announced by CASA, exemplifies the dynamic nature of this regulatory process, which is responsive to both national and international aviation safety requirements.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows CASA to issue ADs for certain kinds of aircraft or aeronautical products. These directives are formal regulatory tools designed to maintain the airworthiness of aircraft, ensuring they meet the required safety standards.
Under these provisions, CASA has issued, reviewed, and subsequently cancelled AD/PR/13 concerning Dowty-Rotol propellers. This action was taken in alignment with Australia’s obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design (in this case, Australia) has the overall responsibility for the continuing airworthiness of engine types and must provide necessary information to the States of Registry. The State of Registry is then responsible for ensuring the continuing airworthiness of individual aircraft, including the propellers installed in them. Given these international obligations, CASA determined that cancelling the AD was necessary, with the cancellation becoming effective on 19 November 2009. No replacement AD is required as a result of this cancellation.
In terms of obligations, CASA, as the regulatory authority, must ensure that ADs are issued, reviewed, and updated or cancelled as necessary to maintain the safety standards of air navigation. The State of Registry, typically Australia in this context, is obligated to ensure that aircraft and their components meet the standards set forth by CASA and comply with international conventions. These obligations are critical to maintaining the safety and integrity of civil aviation within Australia.
For breaches of the provisions set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, there are potential civil and criminal consequences. Although specific penalties are not detailed in the provided text, it is well-established within Australian law that non-compliance with aviation safety regulations can lead to significant penalties, including fines and imprisonment. The exact penalties would depend on the severity of the breach and the specific regulatory provisions violated.
