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/DHA-3/3 affecting De Havilland DHA-3 (Drover) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHA-3/3. The cancellation will become effective on 20 November 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, Airframe and Structures, 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, is designed to regulate civil aviation in the interests of safety, efficiency, and economic development. It provides the framework for the safety oversight of aviation operations and the certification of aircraft and aeronautical products within Australia. The Act empowers the Governor-General to make regulations that are crucial for ensuring the safety of air navigation. The Civil Aviation Safety Regulations 1998, which are subordinate legislation made under the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products to maintain their airworthiness. These ADs serve as legislative instruments and must comply with the Legislative Instruments Act 2003. The issuance and management of ADs are governed by international standards under Annex 8 to the Convention on International Civil Aviation, where the State of Design has the responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must ensure the aircraft’s ongoing airworthiness. CASA, acting as Australia’s national airworthiness authority, must evaluate international ADs and, if necessary, issue Australian ADs to enforce the required safety measures. The authority to issue ADs and the process for their cancellation are outlined in the Civil Aviation Act 1988, reflecting Australia’s commitment to international civil aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) aimed at ensuring the safety of air navigation. These directives apply to specific types of aircraft or aeronautical products, and CASA, acting as Australia's national airworthiness authority, is responsible for issuing such directives when deemed necessary, particularly in response to ADs issued by the aircraft's State of Design. The geographic reach of these regulations is national, with the State of Registry of an individual aircraft also having responsibility for its continuing airworthiness under international agreements such as Annex 8 to the Convention on International Civil Aviation. Notably, ADs are legislative instruments that can be disallowed under the Acts Interpretation Act 1901, and they do not require a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. In specific instances, such as the cancellation of AD/DHA-3/3 for De Havilland DHA-3 (Drover) model aeroplanes, CASA has the authority to make these decisions based on the assessment of continuing airworthiness and the absence of unsafe conditions.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for airworthiness directives (ADs) in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations necessary for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901 and are regulated under the Legislative Instruments Act 2003.
Under the Convention on International Civil Aviation, the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. When an AD is issued by the State of Design, CASA must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. In this case, CASA has assessed and subsequently cancelled Australian AD/DHA-3/3, which affected De Havilland DHA-3 (Drover) model aeroplanes. The cancellation, effective from 20 November 2008, was due to the unsafe condition no longer existing, and no replacement AD was required.
Obligations under the Act and Regulations include ensuring that the State of Design provides all necessary information for the continuing airworthiness of aircraft types, and that the State of Registry implements measures to ensure the airworthiness of individual aircraft. CASA’s role involves assessing ADs issued by the State of Design and determining whether to issue an Australian AD. The obligations also encompass the requirement for CASA to cancel an AD when the unsafe condition it was addressing no longer exists.
The Civil Aviation Safety Regulations 1998 outline that ADs are not subject to consultation with the Australian public or the need for a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This decision is based on the nature of ADs as continuing airworthiness information, which does not necessitate public consultation or a comprehensive regulatory impact analysis. CASA’s decision to cancel AD/DHA-3/3 was made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, in accordance with subsection 84A(2) of the Act, ensuring the process is managed by appropriately qualified personnel.
Breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to various civil and criminal consequences. For example, failing to comply with an AD can result in penalties for aircraft operators, including fines and potential criminal charges. The specific penalties for breaches of these regulations can vary depending on the severity of the violation and the context in which it occurs. In some cases, significant non-compliance can lead to substantial fines or imprisonment, reflecting the critical nature of air safety regulations.
