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 65/7 Amendment 1 affecting Beechcraft A65 and 65-B80 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 65/7 Amendment 1. The cancellation will become effective on 3 July 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, establishes the legislative framework for ensuring the safety and efficiency of civil aviation in Australia. To further operationalise the provisions of this Act, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed regulatory requirements, including the issuance of airworthiness directives. This legislative instrument was designed to address the need for consistent and enforceable standards to ensure the continuing airworthiness of aircraft, thereby fulfilling the safety obligations outlined in international conventions such as the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) plays a critical role in this framework by issuing airworthiness directives that mandate specific safety measures for aircraft types registered in Australia. The objective of these directives is to maintain the highest safety standards in accordance with both national and international aviation safety protocols.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, specifically the Civil Aviation Safety Regulations 1998, govern the issuance of airworthiness directives (ADs) in Australia. The Act applies to entities involved in civil aviation, particularly the Civil Aviation Safety Authority (CASA), which is responsible for ensuring the safety of air navigation in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises CASA to issue ADs for specific types of aircraft or aeronautical products, thereby extending the regulatory framework to ensure continuing airworthiness. The scope of these directives is further defined by subregulation 39.001(5), which classifies ADs as disallowable instruments under the Acts Interpretation Act 1901, thus recognising their status as legislative instruments. These directives are integral to fulfilling Australia’s obligations under international agreements, such as Annex 8 to the Convention on International Civil Aviation, which mandates that States of Design provide necessary information to States of Registry to maintain airworthiness. The geographic reach of the ADs is effectively national, as CASA, acting on behalf of Australia, must issue corresponding directives when required by the State of Design. The application of these regulations is thus broad, affecting both domestic and international aviation entities operating within Australia.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to enact regulations intended to ensure the safety of air navigation. Under this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
In practice, the State of Design, which is the country responsible for the design of the aircraft, has the primary responsibility for the continuing airworthiness of an aircraft type. This responsibility includes providing necessary information to ensure the aircraft remains airworthy, and this information is usually communicated through ADs. The State of Registry, which is the country where the aircraft is registered, must also ensure the continuing airworthiness of the aircraft by developing or adopting appropriate requirements. For aircraft registered in Australia, CASA is tasked with assessing ADs issued by States of Design and, if necessary, issuing Australian ADs to enforce these requirements.
In a specific instance, CASA issued AD/BEECH 65/7 Amendment 1 concerning the Beechcraft A65 and 65-B80 models. Following an assessment, CASA decided to cancel this directive, effective from 3 July 2008. This cancellation was due to the unsafe condition no longer existing, and no replacement AD was required. The cancellation was made in accordance with Australia's obligations under the Convention on International Civil Aviation, and no consultation with the Australian public or a Regulatory Impact Statement was necessary as determined by the Office of Best Practice Regulation. The directive was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, pursuant to subsection 84A(2) of the Act.
Non-compliance with ADs can lead to serious consequences. Under the Civil Aviation Act 1988, an aircraft cannot be flown unless it complies with applicable ADs. Failure to comply with these requirements can result in severe penalties, including fines of up to $504,000 for individuals and $2.5 million for corporations, as stipulated in section 31 of the Act. Additionally, CASA has the authority to take enforcement actions such as grounding non-compliant aircraft, which can significantly disrupt aviation operations.
