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/CHA/19 affecting Bellanca 8GCBC model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CHA/19. The cancellation will become effective on
7 May 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 was enacted to address the need for a comprehensive framework governing civil aviation in Australia, focusing primarily on the safety of air navigation. The Act empowers the Governor-General to make regulations in the interests of safety, as seen with the subsequent establishment of the Civil Aviation Safety Regulations 1998. Under these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs), which serve as critical tools for ensuring the continuing airworthiness of aircraft and aeronautical products. These ADs are legislative instruments that align with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information for the maintenance of airworthiness. CASA, acting as Australia’s national airworthiness authority, assesses the information from the State of Design and issues Australian ADs to enforce the required safety measures. In this context, CASA has recently cancelled the Australian AD/CHA/19 for Bellanca 8GCBC model aeroplanes, reflecting its commitment to maintaining safety standards in compliance with international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for the regulation of airworthiness directives (ADs) in Australia, which are legislative instruments under the authority of the Governor-General and CASA. The Act applies to all persons and entities involved in civil aviation within Australia, including aircraft manufacturers, operators, and maintenance providers, and mandates their compliance with safety regulations. The application of these regulations extends nationally, aligning with international standards set by the International Civil Aviation Organization (ICAO) under the Convention on International Civil Aviation. The State of Design and the State of Registry of an aircraft both play crucial roles in maintaining the continuing airworthiness of aircraft types and individual aircraft, respectively. CASA, as Australia’s national airworthiness authority, issues Australian ADs in response to ADs from the State of Design to ensure compliance with safety standards. Notably, the cancellation of AD/CHA/19 for the Bellanca 8GCBC model aeroplanes was made in accordance with Australia’s international obligations and did not require public consultation or a Regulatory Impact Statement. This cancellation reflects the dynamic nature of safety regulations, where directives may be revoked when the conditions warranting their issuance are resolved.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to enact regulations for the Act’s purposes and to ensure the safety of air navigation. This provision forms the basis for the Civil Aviation Safety Regulations 1998, which include the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (regulation 39.001). Importantly, these ADs are considered legislative instruments as they are disallowable under section 46A of the Acts Interpretation Act 1901, and they fall under the purview of the Legislative Instruments Act 2003 (section 6).
Under the Civil Aviation Safety Regulations 1998, the State of Design has a primary responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to ensure the ongoing airworthiness of a type to the relevant States of Registry (subregulation 39.001(5)). The State of Registry, on the other hand, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within their jurisdiction. When a State of Design issues an AD, the State of Registry must assess the information and, if appropriate, issue an equivalent AD to enforce the safety requirements. In Australia, the Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority and must comply with these regulations by issuing or cancelling ADs as required.
For example, CASA issued AD/CHA/19 for Bellanca 8GCBC model aeroplanes, but subsequently cancelled this AD after determining that the unsafe condition no longer existed. This cancellation was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, and thus no public consultation or Regulatory Impact Statement was required. The AD cancellation was made effective on 7 May 2009 by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, under subsection 84A(2) of the Act.
Failure to comply with the ADs can result in significant consequences, including civil and criminal penalties. Civil Aviation Safety Regulations 1998 outline the regulatory framework that governs these consequences. The specific offences and penalties can vary, but they often include fines and imprisonment for individuals and corporations found guilty of non-compliance. The maximum penalties can be substantial, reflecting the importance of ensuring air safety and the potential risks associated with non-compliance.
