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/CESSNA 310/23 affecting Cessna 310 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/23. The cancellation will become effective on 8 May 2008. 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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to regulate civil aviation and ensure the safety of air navigation, empowers the Governor-General to make regulations for the Act's purposes, specifically under section 98. The Civil Aviation Safety Regulations 1998 further elaborate on these regulations, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as legislative instruments, are subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Civil Aviation Act 1988, through CASA, implements obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design of an aircraft type holds responsibility for ensuring its continuing airworthiness. CASA, as Australia’s national airworthiness authority, must assess information provided by the State of Design and, if necessary, issue Australian ADs to enforce these requirements. In this context, CASA has cancelled the Australian AD/CESSNA 310/23 for Cessna 310 aircraft, effective from 8 May 2008, as the unsafe condition it was addressing no longer exists.
Scope and Application
The Civil Aviation Act 1988, in conjunction with 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, as per regulation 39.001. This Act applies to entities involved in the operation and maintenance of aircraft registered in Australia, mandating adherence to safety standards and procedures. These regulations extend to the national jurisdiction of Australia and align with the international standards set by the International Civil Aviation Organization (ICAO). The Act imposes obligations on the State of Design to provide continuing airworthiness information and on the State of Registry to ensure the airworthiness of aircraft. Notably, ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. The application of these regulations may be extended or restricted through subordinate instruments, ensuring flexibility in addressing evolving safety concerns. While the Act broadly applies to all relevant entities, specific exclusions or exemptions are not detailed within the scope of this particular AD cancellation.
Key Provisions
The Civil Aviation Act 1988, as amended and supported by the Civil Aviation Safety Regulations 1998, provides a robust framework for ensuring the safety of civil aviation in Australia. Section 98 of the Act empowers the Governor-General to make regulations that support the overarching goal of air navigation safety. Regulation 39.001 under the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are intended to address any safety issues that may arise during the operational life of an aircraft.
The obligations under the Act require CASA to meticulously assess the continuing airworthiness of aircraft registered in Australia. When an AD is issued by the State of Design, CASA must evaluate this directive and, if necessary, issue a corresponding Australian AD to ensure compliance with the safety requirements. This process underscores the shared responsibility between the State of Design and the State of Registry in maintaining the airworthiness of aircraft, as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, is tasked with ensuring that individual aircraft meet safety standards.
Failure to comply with the provisions of the Act and the associated regulations can lead to significant consequences. Although specific offences and penalties are not detailed within this particular piece of legislation, the overarching framework of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide for substantial penalties for non-compliance. Offences under these Acts can result in both civil and criminal penalties, including fines and imprisonment, depending on the severity of the breach. The legislative instruments, such as ADs, are designed to enforce compliance and mitigate risks associated with aviation safety.
In summary, the Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides a comprehensive regulatory environment to maintain and ensure the safety of civil aviation in Australia. CASA's role in issuing and enforcing ADs is crucial to upholding these safety standards, and non-compliance can result in serious legal repercussions. The legislative process also reflects Australia's commitment to international aviation safety standards, as outlined in the Convention on International Civil Aviation.
