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 180/53 affecting Cessna 180 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 3 July 2008. 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, 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 by the Australian Parliament, serves to regulate the safety and efficiency of civil aviation in Australia. This legislation was introduced to ensure the safety of air navigation and to address the need for comprehensive regulations governing the civil aviation sector. Under this Act, the Civil Aviation Safety Regulations 1998 were established, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are critical for maintaining the continuing airworthiness of aircraft and are issued in compliance with international standards set by the Convention on International Civil Aviation. The enactment of the Civil Aviation Act 1988 and subsequent regulations was driven by the need to uphold high safety standards in civil aviation, ensuring both national and international compliance with airworthiness requirements. The ADs, which are legislative instruments, reflect Australia's commitment to international civil aviation obligations and the continuous improvement of air safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, which are considered legislative instruments, are integral to maintaining the continuing airworthiness of aircraft, as per the requirements set out in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to ensure compliance, and the State of Registry must implement these directives to ensure the safety of individual aircraft within its jurisdiction. In the case of Australia, CASA, as the national airworthiness authority, is tasked with assessing and, if necessary, issuing ADs that align with the directives of the State of Design. The AD/CESSNA 180/53, which previously affected Cessna 180 aircraft, has been reviewed and subsequently cancelled by CASA, effective from 3 July 2008, due to Australia’s international obligations under the Convention on International Civil Aviation, without the need for public consultation or a Regulatory Impact Statement. This cancellation was authorised by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, acting on behalf of CASA, in accordance with the provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations for the Act's purposes, particularly in the interest of air navigation safety. This framework allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. Importantly, an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and a legislative instrument under section 6 of the Legislative Instruments Act 2003, as per subregulation 39.001(5). These directives are essential for maintaining the continuing airworthiness of aircraft types, a responsibility that the State of Design must uphold under Annex 8 of the Convention on International Civil Aviation, ensuring the provision of necessary information to the States of Registry.
Entities governed by this legislation, such as CASA and the States of Registry, have distinct responsibilities. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design regarding ADs and issue Australian ADs if appropriate. States of Registry are mandated to develop or adopt requirements to ensure the continuing airworthiness of individual aircraft within their registry. The State of Design has the overarching responsibility for the airworthiness of an aircraft type and must provide relevant information to the States of Registry. These obligations are crucial for maintaining safety standards in civil aviation.
Failure to comply with the requirements set out in the ADs could lead to severe consequences. The Civil Aviation Act 1988 does not explicitly detail the penalties for non-compliance with ADs, but generally, non-compliance with aviation safety regulations can result in significant penalties. Such penalties may include fines and other civil or criminal sanctions. It is also worth noting that the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, which might imply that these directives are issued with a focus on immediate safety rather than economic impact assessments.
