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.
The Civil Aviation Safety Authority or its predecessors issued AD/DHC-2/1 affecting all De Havilland DHC-2 (Beaver) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-2/1. The cancellation will become effective on 23 October 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 Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, governs the regulation of civil aviation in Australia with a focus on safety and efficiency. This Act empowers the Governor-General to make regulations for the purposes of the Act, ensuring that air navigation safety is prioritised. Under the Act, the Civil Aviation Safety Regulations 1998 were established to provide further detail on safety standards and procedures. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, thus enabling CASA to address safety concerns and maintain airworthiness. The process for issuing and cancelling ADs, such as the recent cancellation of AD/DHC-2/1 for De Havilland DHC-2 (Beaver) model aeroplanes, is conducted in accordance with Australia’s obligations under international conventions, particularly Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for the continuing airworthiness of aircraft to the States of Design and Registry.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory authority is grounded in section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations aimed at ensuring the safety of air navigation. These airworthiness directives are legislative instruments as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, aligning with Annex 8 of the Convention on International Civil Aviation. The State of Design holds primary responsibility for ensuring the airworthiness of aircraft types, while the State of Registry is tasked with implementing specific requirements to maintain airworthiness. The issuance and cancellation of ADs, such as the case with AD/DHC-2/1 for De Havilland DHC-2 (Beaver) model aeroplanes, are conducted in compliance with these international and domestic regulatory frameworks. Notably, the cancellation of such directives does not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to establish regulations that ensure the safety of air navigation. This act serves as the foundation for the Civil Aviation Safety Regulations 1998, which are designed to maintain safety standards across the aviation industry. Regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. This regulatory provision is crucial in maintaining the safety and airworthiness of aircraft operating within Australia. The ADs, as per subregulation 39.001(5), are considered disallowable instruments under the Acts Interpretation Act 1901, and therefore they are legislative instruments as outlined in section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant for both CASA and the entities they govern. CASA has the responsibility to issue ADs when necessary to ensure the continuing airworthiness of aircraft types. The State of Design must provide all necessary information to support the airworthiness of a type of aircraft to the State of Registry, in accordance with Annex 8 to the Convention on International Civil Aviation. The State of Registry, in turn, is responsible for the ongoing airworthiness of individual aircraft, which includes developing or adopting requirements to maintain these standards. These obligations ensure that both the design and registry states work collaboratively to uphold the highest safety standards in aviation.
Failure to comply with the requirements set forth in the Civil Aviation Safety Regulations 1998 can result in serious consequences. Offences under these regulations can lead to both civil and criminal penalties. Civil penalties may include fines and other sanctions imposed by CASA, while criminal penalties could involve imprisonment and fines, depending on the severity of the breach. The maximum penalties for non-compliance are outlined in the relevant sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. These stringent measures underscore the importance of adhering to airworthiness directives and the overarching regulations designed to protect public safety in aviation.
