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/AUS/4 affecting Auster/Beagle A.61 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AUS/4. The cancellation will become effective on 30 July 2009. 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 Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the safety and efficiency of civil aviation in Australia. The Act empowers the Governor-General to make regulations that ensure the safety of air navigation, which includes the issuance of airworthiness directives (ADs) as stipulated in the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments under the Acts Interpretation Act 1901 and are used to mandate requirements to maintain the continuing airworthiness of aircraft. The Civil Aviation Safety Authority (CASA) acts on behalf of the Australian government as the national airworthiness authority, issuing and cancelling ADs in accordance with Australia's obligations under the Convention on International Civil Aviation. The policy objective is to ensure that aircraft operating within Australia meet international safety standards, thus maintaining the safety of air navigation and the integrity of the Australian Register.
Scope and Application
The Civil Aviation Act 1988 and associated Civil Aviation Safety Regulations 1998 provide the legal framework for the regulation of civil aviation in Australia, particularly concerning the safety and airworthiness of aircraft. Under this Act, the Governor-General is empowered to make regulations to ensure the safety of air navigation, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments that mandate compliance with safety standards, and they can be issued in response to identified safety issues with specific aircraft types or components. The application of ADs is not limited to Australian-registered aircraft but extends to ensuring that international standards and obligations under the Convention on International Civil Aviation are met. The State of Design, typically the manufacturer of the aircraft, has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, such as Australia, must ensure that the aircraft remains airworthy by adopting and enforcing relevant ADs. This regulatory approach ensures that the safety standards applicable to aircraft are consistently applied across all jurisdictions, with CASA playing a crucial role in enforcing these standards in Australia.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to establish regulations that aim to enhance the safety of air navigation. This legislative framework is further detailed in regulation 39.001 of the Civil Aviation Safety Regulations 1998, which grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they fall within the legislative instruments category as defined in the Legislative Instruments Act 2003. The ADs are a critical tool for ensuring that aircraft maintain their airworthiness, as stipulated by Annex 8 to the Convention on International Civil Aviation.
Under the Act and its regulations, CASA, as Australia’s national airworthiness authority, is tasked with the responsibility of assessing the information provided by the State of Design when an AD is issued against an aircraft type registered in Australia. If necessary, CASA must issue its own AD to enforce the requirements specified by the State of Design. This process ensures that the continuing airworthiness of aircraft registered in Australia is maintained in accordance with international standards. The State of Registry holds the ultimate responsibility for the airworthiness of each individual aircraft, which involves developing or adopting the necessary requirements to uphold airworthiness.
An example of this regulatory process is seen in AD/AUS/4, which affected Auster/Beagle A.61 series aeroplanes. CASA assessed the AD and, finding that the unsafe condition it addressed no longer existed, decided to cancel the directive. This cancellation became effective on 30 July 2009, and no replacement AD was deemed necessary. Given that the cancellation was in compliance with Australia’s obligations under the Convention on International Civil Aviation, there was no requirement for public consultation or the preparation of a Regulatory Impact Statement. The AD was issued by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of compliance, entities and individuals subject to ADs must adhere to the specified requirements to maintain the airworthiness of their aircraft. Failure to comply with an AD can lead to serious safety implications, potentially resulting in aircraft being grounded or prohibited from flight. Under the Civil Aviation Act 1988, non-compliance with ADs may be subject to civil and criminal penalties. The severity of these penalties can vary, with potential fines and imprisonment for breaches that result in significant safety risks. The specific penalties are outlined in the Act and can be severe, reflecting the importance of airworthiness and safety in aviation.
