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 185/20 affecting Cessna 185 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, 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, enacted by the Australian Parliament, was established to ensure the safety and efficiency of civil aviation within Australia. This Act provides the legislative framework under which the Civil Aviation Safety Regulations 1998 were made to further detail the regulatory requirements for airworthiness and safety. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are legislative instruments as defined under the Legislative Instruments Act 2003. This regulatory mechanism ensures compliance with international standards set forth by the Convention on International Civil Aviation, particularly Annex 8, which mandates the State of Design to maintain the continuing airworthiness of aircraft types and for the State of Registry to enforce these standards domestically. CASA’s role is pivotal in this framework, as it must assess and, if necessary, mandate the requirements of foreign ADs for aircraft registered in Australia. In line with these obligations, CASA has cancelled AD/CESSNA 185/20 concerning Cessna 185 aircraft, effective from 3 July 2008, without the need for a replacement AD, in adherence to Australia’s international commitments.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, mandates the creation of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products. These directives apply to specific types of aircraft or aeronautical products as outlined in the regulations, and CASA is tasked with assessing and issuing these directives in accordance with the safety standards set forth by the State of Design and the Convention on International Civil Aviation. The application of these regulations extends across the Commonwealth of Australia, with CASA acting as the national airworthiness authority responsible for ensuring the continuing airworthiness of aircraft registered in Australia. The ADs are legislative instruments under the Legislative Instruments Act 2003 and can be issued without the need for consultation with the Australian public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The Act provides CASA with the authority to issue, modify, or cancel ADs as necessary to comply with international obligations and ensure the safety of air navigation.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) under section 98 of the Act (subsection 39.001(5)). These ADs are legislative instruments and are essential for ensuring the continuing airworthiness of aircraft and aeronautical products. Under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for providing necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry, such as CASA in Australia, is responsible for implementing these requirements within their jurisdiction.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties governed by the Act include the duty for CASA to assess and, if necessary, issue Australian ADs when a State of Design issues an AD affecting aircraft on the Australian Register. This ensures that Australian aircraft comply with international standards for airworthiness. Additionally, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft, ensuring that all aircraft operating within its jurisdiction meet the necessary safety standards.
Breach of the regulations or failure to comply with an AD may result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD could lead to civil penalties, including fines, and potentially criminal charges if the breach results in serious harm or death. The specific penalties for breaches are not detailed within the text, but they can be substantial, reflecting the critical importance of adhering to airworthiness directives. CASA, as the national airworthiness authority, has the responsibility to enforce compliance and take appropriate action against non-compliance to maintain the high safety standards required in civil aviation.
