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/BELL 206/32 affecting Bell 206A and AB 206A model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the safety of civil aviation in Australia, including the regulation of aircraft and aeronautical products to ensure their airworthiness. The Act empowers the Governor-General to make regulations that support the Act's objectives, particularly in relation to the safety of air navigation. One such regulation, regulation 39.001 of the Civil Aviation Safety Regulations 1998, enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that must be assessed and potentially adopted by the State of Registry to ensure the continuing airworthiness of aircraft registered in Australia, aligning with international standards under Annex 8 of the Convention on International Civil Aviation. CASA, as the national airworthiness authority, plays a critical role in evaluating ADs issued by States of Design and determining their applicability in Australia.
Scope and Application
The Civil Aviation Act 1988 applies to all persons and entities involved in civil aviation within Australia, including aircraft operators, pilots, maintenance personnel, and aviation service providers. The Act, alongside the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are legislative instruments aimed at ensuring the continuing airworthiness of aircraft. The ADs are issued under the authority granted by regulation 39.001 of the Civil Aviation Safety Regulations 1998, with specific reference to Annex 8 of the Convention on International Civil Aviation. The ADs are applicable nationally and align with international standards set by the International Civil Aviation Organization (ICAO). The State of Registry, which in the context of Australia is CASA, is responsible for ensuring the airworthiness of individual aircraft registered within Australia. The ADs can be issued for specific types of aircraft or aeronautical products and, when issued by the State of Design, require CASA to assess and potentially issue corresponding ADs for aircraft registered in Australia. The cancellation of AD/BELL 206/32 for the Bell 206A and AB 206A model aircraft exemplifies the application of this process. The AD was cancelled following the determination that the unsafe condition it addressed no longer existed, and this action was taken in accordance with Australia's obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the mechanisms by which airworthiness directives (ADs) are issued and managed. Section 98 of the Act empowers the Governor-General to create regulations for air navigation safety, while regulation 39.001 of the Safety Regulations permits the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) specifies that ADs are disallowable instruments under the Acts Interpretation Act 1901 and, therefore, are legislative instruments under the Legislative Instruments Act 2003. This framework ensures that ADs are formally recognised and enforceable as part of the regulatory system.
The obligations under this legislation require the State of Design to maintain the continuing airworthiness of an aircraft type and to provide necessary information to States of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. For Australia, this means that when a State of Design issues an AD, CASA must review the information and, if deemed necessary, issue an Australian AD to enforce the required safety measures. The State of Registry, in this case CASA, is tasked with ensuring the continuing airworthiness of aircraft registered in Australia, thereby fulfilling their responsibilities under Annex 8.
There are specific obligations for both the State of Design and the State of Registry to ensure that ADs are issued and enforced appropriately. The State of Design must identify and communicate any safety issues related to an aircraft type, while the State of Registry, represented by CASA, must assess these communications and issue corresponding ADs where necessary. This collaborative approach ensures that safety standards are uniformly applied across all aircraft registered within the State of Registry.
Regarding the consequences of non-compliance, the Civil Aviation Act 1988 and associated regulations do not specify explicit offences, penalties, or civil/criminal consequences for breaching ADs. However, the enforcement of ADs is critical for maintaining air safety, and failure to comply with these directives can lead to severe operational and safety risks. While the Act does not detail maximum penalties for non-compliance with ADs, the overarching regulatory framework implies that non-compliance could result in significant legal and operational repercussions, including potential grounding of aircraft and other enforcement actions by CASA.
