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/RAD/46 affecting Bendix/King VN 411B VHF navigation receivers. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/46. The cancellation will become effective on 9 April 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, provides a legal framework for the regulation of civil aviation within Australia. It aims to ensure the safety and efficiency of civil aviation operations in Australia, including the issuance of airworthiness directives to maintain the safety of aircraft. The Civil Aviation Safety Regulations 1998 further elaborate on the implementation of these directives, allowing the Civil Aviation Safety Authority (CASA) to issue such directives for specific kinds of aircraft or aeronautical products. This legislative instrument is designed to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), ensuring that Australia meets its obligations under the Convention on International Civil Aviation. The Act allows CASA to issue and cancel airworthiness directives based on assessments of continuing airworthiness, in accordance with international obligations and domestic safety requirements. The process of issuing or cancelling an airworthiness directive is intended to ensure that the continuing airworthiness of aircraft on the Australian Register is maintained, in line with international standards and domestic safety objectives.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, outlines the regulatory framework for civil aviation safety in Australia, with a particular focus on ensuring the continuing airworthiness of aircraft. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to address safety concerns. These ADs are legislative instruments, subject to disallowance and parliamentary scrutiny, and are intended to align with international standards set by the International Civil Aviation Organization (ICAO). The geographic reach of these regulations is national, as CASA operates as Australia’s primary authority for civil aviation safety, overseeing both the State of Design and State of Registry responsibilities for aircraft registered in Australia. The Act applies to all aircraft operators, manufacturers, and maintenance providers within Australia, ensuring compliance with safety standards mandated by CASA. Any exclusions or exemptions from these regulations would be specified in the subordinate instruments issued by CASA, and while the primary focus is on safety, the legislative process ensures transparency and accountability in the regulation of civil aviation activities.
Key Provisions
The Civil Aviation Act 1988, and specifically section 98, provides the authority for the Governor-General to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. Essentially, ADs are tools that ensure the continuing airworthiness of aircraft and aeronautical products, aligning with the obligations of the State of Design and State of Registry as per Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and the associated regulations primarily fall on CASA, as Australia’s national airworthiness authority. When a State of Design issues an AD against a type of aircraft registered in Australia, CASA must evaluate the information provided and, if necessary, issue an Australian AD to enforce the requirements set forth by the State of Design. This ensures that the aircraft on the Australian register meet the safety standards stipulated by international conventions and agreements. Moreover, CASA must ensure that any ADs issued are in line with Australia’s obligations under the Convention on International Civil Aviation and that they adhere to the established safety regulations.
Failure to comply with the requirements set out in ADs can lead to various civil and criminal consequences. While the specific offences and penalties for breaching ADs are not detailed in the provided text, it is understood that non-compliance can result in significant regulatory action, including fines and potential criminal charges, depending on the severity of the breach and its impact on safety. The exact penalties would be determined based on the relevant aviation regulations and safety standards in place.
In the specific case of AD/RAD/46, which pertained to Bendix/King VN 411B VHF navigation receivers, CASA assessed the situation and determined that the unsafe condition no longer existed. Consequently, the Australian AD/RAD/46 was cancelled, effective from 9 April 2009. As this cancellation was due to Australia’s obligations under the Convention on International Civil Aviation, there was no requirement for public consultation or the preparation of a Regulatory Impact Statement. The AD was issued 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.
