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.
CASA issued AD/RES/16, affecting certain types of safety harness end fittings in 1984. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 22 November 2007. No replacement AD is required, as the original unsafe condition no longer exists, the affected parts having long been removed from service.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes in the Airworthiness Engineering Branch, 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, ensuring safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, as demonstrated by the Civil Aviation Safety Regulations 1998. One such regulation, 39.001, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are critical for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. In this context, CASA plays a pivotal role in assessing and implementing ADs to safeguard Australian-registered aircraft, ensuring they meet the necessary safety standards.
Scope and Application
The Civil Aviation Act 1988, and its associated Civil Aviation Safety Regulations 1998, apply to entities involved in the design, manufacture, and operation of aircraft within Australia. The Act, particularly under section 98, empowers the Governor-General to enact regulations in the interest of air navigation safety, with CASA (Civil Aviation Safety Authority) being tasked with implementing these regulations. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows CASA to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments and serve as crucial mechanisms for maintaining the continuing airworthiness of aircraft, as per international standards set by Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in Australia is CASA, holds the responsibility for ensuring the airworthiness of aircraft registered within its jurisdiction. The scope of these regulations is broad, covering various types of aircraft and aeronautical products, but they do not require public consultation or a Regulatory Impact Statement when cancelling an AD, as seen in the case of AD/RES/16, which has been cancelled due to the original unsafe condition no longer existing.
Key Provisions
Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that support the Act's purpose of ensuring the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulation is recognised as a legislative instrument under the Legislative Instruments Act 2003. ADs are a critical means by which the continuing airworthiness of aircraft is ensured, as stipulated in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions on CASA and other relevant authorities include ensuring that ADs are issued when necessary to maintain airworthiness. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to the State of Registry, which is then tasked with developing or adopting requirements to maintain the airworthiness of individual aircraft. For instance, when a State of Design issues an AD against an aircraft type on the Australian Register, CASA must assess the information and issue an Australian AD if appropriate. The State of Registry must also implement the requirements set forth in these ADs.
Failure to comply with ADs can result in serious consequences, including potential criminal or civil penalties. While the specific penalties are not detailed in the given text, it is known that non-compliance with safety regulations can lead to substantial fines and other legal repercussions. The regulatory framework is designed to ensure that aircraft remain airworthy and safe for operation, and any breach of these regulations can have significant implications for those involved.
In the case of AD/RES/16, which was issued in 1984 concerning certain types of safety harness end fittings, CASA has determined that the directive can be cancelled as the unsafe condition it addressed no longer exists. This cancellation will take effect on 22 November 2007, and no replacement AD is necessary. The decision to cancel the AD was made without public consultation, as it reduces the regulatory burden, and the Office of Best Practice Regulation has confirmed that a Regulatory Impact Statement is not required. The AD cancellation was authorised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in line with subsection 84A(2) of the Act.
