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 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.
CASA or its predecessors issued AD/TPE 331/21 affecting Honeywell TPE 331 engines in 1975. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 24 September 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, Future 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 regulate civil aviation in Australia and to ensure the safety of air navigation, with the overarching aim of protecting the public from the risks associated with civil aviation. The Act provides the legal framework for the Civil Aviation Safety Authority (CASA) to issue regulations aimed at maintaining the highest safety standards in aviation. One such regulation, the Civil Aviation Safety Regulations 1998, empowers CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. ADs are a key regulatory tool used by CASA to communicate safety-critical information and ensure that aircraft remain in a safe condition for operation. The Civil Aviation Act 1988 thus addresses the need for a robust regulatory system to manage the complexities and inherent risks of civil aviation, aligning with Australia's obligations under international agreements such as the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, as stipulated in regulation 39.001. This legislative framework ensures that ADs are issued in the interests of air navigation safety, with such directives being classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and legislative instruments under section 6 of the Legislative Instruments Act 2003. These directives align with the continuing airworthiness requirements set forth in Annex 8 to the Convention on International Civil Aviation, whereby the State of Design and the State of Registry bear responsibilities for the ongoing airworthiness of aircraft. The ADs serve as a critical means of communication for maintaining airworthiness standards across international borders. CASA's issuance of these directives is underpinned by Australia's international obligations and domestic safety mandates, ensuring that the regulations are both comprehensive and globally compliant. The cancellation of specific ADs, such as AD/TPE 331/21 concerning Honeywell TPE 331 engines, is executed in accordance with Australia's adherence to international aviation conventions and does not necessitate public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations that support the Act's primary aim of ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants CASA the authority to issue ADs for specific kinds of aircraft or aeronautical products. This regulatory power is crucial for maintaining and ensuring the ongoing airworthiness of aircraft, thereby safeguarding public safety in aviation. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and, as such, are legislative instruments in accordance with the Legislative Instruments Act 2003.
The obligations imposed by these regulations on CASA and other relevant parties are substantial. CASA is mandated to issue ADs as necessary to maintain the airworthiness of aircraft and aeronautical products. The State of Design, which is the country where the aircraft was originally designed, bears the responsibility for ensuring the continuing airworthiness of an aircraft type, including providing necessary information to States of Registry. The State of Registry, on the other hand, is responsible for the ongoing airworthiness of individual aircraft and must implement requirements to uphold this responsibility. This division of responsibilities ensures a comprehensive approach to maintaining airworthiness standards across different jurisdictions and stakeholders.
Failure to comply with the provisions of ADs can lead to severe consequences, including potential criminal and civil penalties. Although specific penalties are not detailed in the text provided, non-compliance with ADs generally results in violations that can be prosecuted under the Civil Aviation Act 1988 and related regulations. These violations can carry significant penalties, reflecting the high stakes involved in ensuring the safety and airworthiness of aircraft. The cancellation of an AD, such as AD/TPE 331/21 affecting Honeywell TPE 331 engines, signifies the importance of adhering to regulatory requirements and the potential for regulatory actions to evolve in response to international obligations and safety standards.
