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/PA-28/71 affecting Piper PA-28 model aircraft, in 1978. 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 all affected aircraft would have been modified long ago.
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 establish a comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation and operations. The Civil Aviation Safety Regulations 1998 complement this Act by detailing specific safety requirements, including the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations necessary for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. The policy objective is to maintain the highest standards of airworthiness, ensuring that aircraft and aeronautical products remain safe throughout their operational life. The authority to issue and cancel ADs is vested in CASA, which acts as the national airworthiness authority, ensuring compliance with both domestic and international standards as set out in Annex 8 to the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, mandate requirements necessary for the continuing airworthiness of aircraft. The State of Registry, in this case CASA, has the responsibility of ensuring that aircraft registered in Australia comply with these directives. The Civil Aviation Act 1988 and the associated regulations apply to all aircraft registered in Australia, their operators, and relevant personnel, with CASA acting as the national airworthiness authority. The geographic reach of these regulations is national, as they pertain to aircraft operating within Australian airspace. While the Act and its subordinate regulations broadly apply to all relevant entities and conduct, specific ADs may target particular aircraft types or products based on identified safety concerns. Any exclusions or exemptions would typically be detailed within the specific ADs themselves, rather than in the overarching Act or regulations.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework within which airworthiness directives (ADs) are issued and managed in Australia. According to section 98 of the Civil Aviation Act 1988, the Governor-General can make regulations to ensure the safety of air navigation, which includes the issuance of ADs. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs 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.
The obligations imposed by these regulations require the State of Design, which is responsible for the continuing airworthiness of an aircraft type, to provide necessary information to ensure the aircraft's safety. The State of Registry, which is the country where the aircraft is registered, must adopt or develop requirements to ensure the continuing airworthiness of the aircraft. CASA, as Australia’s national airworthiness authority, is tasked with assessing the information provided by the State of Design and issuing an Australian AD if necessary. This process ensures that Australian-registered aircraft meet international safety standards.
In specific instances, CASA may cancel an existing AD. For example, AD/PA-28/71, issued in 1978 for Piper PA-28 model aircraft, has been reviewed and is set to be cancelled on 3 July 2008. The decision to cancel this AD was made because all affected aircraft have already been modified, and no further regulatory action is required. Since the cancellation reduces the regulatory burden, no consultation with the Australian public was deemed necessary. The Office of Best Practice Regulation has also determined that such cancellations do not require a Regulatory Impact Statement.
Failure to comply with ADs or other regulations can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines, and in some cases, criminal charges. The exact penalties depend on the nature and severity of the breach but can include substantial financial penalties and imprisonment. CASA enforces these regulations rigorously to maintain the high safety standards expected in civil aviation.
