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/CESSNA 180/28 Amendment 1, affecting Cessna 180 model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as normal maintenance practices now address the unsafe condition.
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 ensure the safety and efficiency of civil aviation in Australia. The Act provides the legal framework for the regulation of civil aviation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This legislation was introduced to address the need for a comprehensive regulatory approach to air safety, ensuring that aircraft and aeronautical products meet the required safety standards. The Civil Aviation Safety Regulations 1998 further elaborate on the implementation of these directives, empowering CASA to issue ADs for specific types of aircraft or aeronautical products. The policy objective of this legislation is to maintain and enhance the safety of air navigation by ensuring that all aircraft within Australia's jurisdiction comply with stringent airworthiness standards. The ADs serve as a critical tool for communicating necessary safety measures and updates to aircraft operators and the aviation industry.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to any entities and individuals involved in the aviation industry in Australia, including aircraft manufacturers, operators, and regulatory authorities such as the Civil Aviation Safety Authority (CASA). These regulations are concerned with ensuring the safety of air navigation and the continuing airworthiness of aircraft registered in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These directives are legislative instruments that, under the Legislative Instruments Act 2003, must be prepared, registered, and tabled in accordance with relevant legislative requirements. The geographic reach of these regulations is national, as they pertain to all aircraft registered in Australia, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The Act and its regulations do not specify any exclusions or exemptions but rely on the international standards and best practices to ensure air safety. The application and enforcement of these regulations may be further detailed through subordinate instruments, which may extend or restrict their application based on specific safety needs or technological advancements.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, grants the Governor-General the authority to make regulations for the Act, focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. It is crucial to note that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, thus, are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the regulations on the parties involved are significant. The State of Design, responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure the safety of the aircraft to appropriate States of Registry. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and, if deemed necessary, issue an Australian AD to enforce the State of Design's requirements. Furthermore, the State of Registry is mandated to develop or adopt requirements to ensure the continuing airworthiness of individual aircraft.
The Civil Aviation Safety Regulations 1998, specifically subregulation 39.001(5), outline that ADs are the primary means of continuing airworthiness information and are issued by most International Civil Aviation Organization (ICAO) Contracting States. These ADs ensure that the necessary safety measures are implemented and maintained. In the case of the AD/CESSNA 180/28 Amendment 1, CASA issued this directive affecting Cessna 180 model aircraft in 1972. Following a review, CASA decided to cancel the AD, effective from 3 July 2008, as the unsafe condition addressed by the AD is now managed through normal maintenance practices. This cancellation reduces the regulatory burden without necessitating a replacement AD.
Regarding the consequences of non-compliance, the Civil Aviation Act 1988 and the associated regulations do not explicitly detail specific offences, penalties, or civil/criminal consequences for breaches of ADs in the provided text. However, failure to comply with ADs could potentially lead to severe safety risks, and CASA might take enforcement actions against the non-compliant party, which could include fines, legal proceedings, or other regulatory measures to ensure compliance and maintain aviation safety standards.
