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/INST/21 affecting King KFC200 IAFCS. CASA has assessed this AD and as a result has cancelled Australian AD/INST/21. The cancellation will become effective on 12 March 2009. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, addresses the need for regulations governing civil aviation to ensure the safety of air navigation. The Act empowers the Governor-General to make such regulations, aligning with the interests of national and international aviation safety standards. One of the key mechanisms through which these regulations are implemented is the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. ADs are critical in maintaining the continuing airworthiness of aircraft, as they provide necessary safety information and mandates based on assessments by aviation authorities such as the Civil Aviation Safety Authority (CASA). These directives are issued in accordance with international standards set by the Convention on International Civil Aviation, ensuring that Australia meets its obligations under these international agreements. CASA, acting as the national airworthiness authority, plays a pivotal role in assessing and issuing ADs to mandate safety requirements derived from both domestic and international sources.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance and management of airworthiness directives (ADs) within Australia. This legislation applies to all aircraft and aeronautical products registered in Australia, ensuring adherence to safety standards established by the Civil Aviation Safety Authority (CASA). The regulations mandate that CASA, as Australia's national airworthiness authority, must issue ADs for specific types of aircraft or aeronautical products identified as requiring safety measures. These ADs, which are legislative instruments under the Acts Interpretation Act 1901, ensure compliance with international standards as outlined in Annex 8 of the Convention on International Civil Aviation. Notably, ADs are issued by the State of Design and must be assessed and potentially adopted by the State of Registry, such as CASA in Australia, to maintain the continuing airworthiness of aircraft. The application of these regulations extends to all entities and individuals involved in the design, manufacture, and operation of aircraft within Australian jurisdiction, ensuring that safety remains a paramount consideration in civil aviation activities.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to establish regulations in the interests of air navigation safety, delegating authority to the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998 to issue airworthiness directives (ADs). These directives are instrumental in maintaining the safety standards of aircraft and aeronautical products. Moreover, these ADs are classified as 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.
These directives are integral to fulfilling the obligations outlined in Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as responsible for the ongoing airworthiness of aircraft types, necessitating the provision of necessary information to the States of Registry. The State of Registry, in turn, must establish or adopt requirements to ensure the continuing airworthiness of aircraft under its jurisdiction. In Australia, CASA, acting as the national airworthiness authority, must evaluate any ADs issued by the State of Design and, if deemed necessary, promulgate corresponding Australian ADs.
The obligations imposed by these regulations require CASA to diligently assess foreign ADs, such as AD/INST/21 affecting the King KFC200 IAFCS, and subsequently determine whether to issue an Australian equivalent. The regulatory framework mandates that CASA must cancel any AD if the associated unsafe condition is no longer present, as demonstrated by the cancellation of Australian AD/INST/21 due to the resolution of the unsafe condition. Furthermore, these obligations extend to ensuring transparency and compliance with the Convention on International Civil Aviation, even in instances where public consultation is not required for AD cancellations.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the associated regulations could lead to significant civil or criminal consequences. The specific offences and penalties are not detailed within the text, but breaches of aviation safety regulations can result in substantial fines and imprisonment. For instance, under section 374 of the Civil Aviation Act 1988, a person can be subject to penalties for non-compliance, with maximum penalties potentially reaching up to $210,000 for corporations and $21,000 for individuals, alongside imprisonment terms that may extend up to five years. Such stringent measures underscore the critical importance of adhering to the airworthiness directives and safety regulations.
