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/BEECH 55/24 affecting all Beechcraft 55, 58 and 95-55 model aircraft fitted with electrical fuel vent heaters. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 55/24. The cancellation will become effective on 5 June 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, provides the legal framework for ensuring the safety of air navigation within Australia. It empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which, among other things, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Registry under Annex 8 of the Convention on International Civil Aviation. This particular legislative instrument addresses the need for Australia to align with international standards and practices for ensuring aircraft safety, by allowing CASA to issue or cancel ADs based on assessments of safety information provided by States of Design. The policy objective is to ensure that Australian aviation standards are consistent with international obligations and practices, thereby enhancing the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively establish the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation in Australia. Under these regulations, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products, which are legislative instruments subject to disallowance. The State of Design of an aircraft holds primary responsibility for its continuing airworthiness, while the State of Registry, in this case CASA as Australia’s national airworthiness authority, must ensure compliance with these standards. This legislative and regulatory structure is designed to align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation. The scope of these ADs encompasses all relevant aircraft registered in Australia, and their application is integral to maintaining the safety standards necessary for Australian airspace.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 revolve around the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act allows the Governor-General to make regulations for the purposes of the Act, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Notably, under subregulation 39.001(5), an AD is considered a disallowable instrument as per section 46A of the Acts Interpretation Act 1901, thus classifying it as a legislative instrument according to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions require the State of Design to maintain the continuing airworthiness of aircraft types and provide necessary information to States of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and, if appropriate, issue Australian ADs to mandate the requirements. This regulatory framework ensures that safety measures are consistently applied across different jurisdictions.
Any failure to comply with ADs may lead to civil or criminal consequences. While specific penalties are not detailed in the provided text, it is clear that non-compliance with airworthiness directives could result in serious safety risks and legal ramifications. The Civil Aviation Safety Regulations 1998, along with other related legislation, likely include provisions for fines, enforcement actions, and potential criminal charges for those who violate ADs, thereby protecting public safety in the aviation sector.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for the issuance and enforcement of ADs. These regulations ensure that aircraft maintain their airworthiness, with CASA playing a critical role in assessing and implementing these directives. Non-compliance with ADs could lead to severe penalties, highlighting the importance of adherence to these safety standards.
