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/ENST 28/3 affecting Enstrom F-28 series helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/ENST 28/3. The cancellation will become effective on 27 August 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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, provides the legislative framework for ensuring the safety of air navigation in Australia. One of the key provisions of the Act allows the Governor-General to make regulations aimed at enhancing the safety of air navigation, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs, which are legislative instruments, are designed to mandate requirements for the continuing airworthiness of aircraft and aeronautical products as per the standards set by the State of Design and adopted by the State of Registry. The Civil Aviation Safety Regulations 1998 further outline the process and authority for CASA to issue ADs to ensure compliance with international standards as established by the Convention on International Civil Aviation. The policy objective underpinning these regulations is to maintain and improve the safety standards in civil aviation by ensuring that all aircraft and aeronautical products meet the necessary airworthiness criteria.
Scope and Application
The Civil Aviation Act 1988 and associated Civil Aviation Safety Regulations 1998 provide the framework for ensuring the safety of air navigation in Australia, and under these laws, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) to maintain the airworthiness of aircraft. ADs are legislative instruments that apply to specific types of aircraft or aeronautical products and are issued when necessary to address safety concerns. CASA, as Australia’s national airworthiness authority, must assess and, if appropriate, mandate the requirements of ADs issued by the State of Design, ensuring that these directives align with Australia's obligations under international agreements such as the Convention on International Civil Aviation. The issuance, assessment, and cancellation of ADs are integral to the continuing airworthiness of aircraft registered in Australia, and they are managed in accordance with the legislative framework provided by the Civil Aviation Act and its regulations. The application of these directives is broad, encompassing all aircraft types and products within the Australian jurisdiction, and they do not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further stipulates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they qualify as legislative instruments under section 6 of the Legislative Instruments Act 2003. This means that ADs have the force of law and are subject to legislative scrutiny.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties involved are significant. The State of Design, which is the country where the aircraft was designed, has the primary responsibility for ensuring the continuing airworthiness of the aircraft type. This entails providing necessary information to the States of Registry, which are the countries where the individual aircraft are registered. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of aircraft within its jurisdiction. CASA, as Australia’s national airworthiness authority, has the duty to assess the ADs issued by the State of Design and, if deemed appropriate, issue Australian ADs to enforce the necessary requirements.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various civil and criminal consequences. The specific offences, penalties, and consequences for non-compliance are not detailed within the provided text. However, the overarching framework suggests that breaches of these regulations could lead to enforcement actions by CASA, including fines, suspension or revocation of airworthiness certificates, and potentially criminal charges in cases of severe non-compliance that result in safety hazards or violations of air navigation safety standards. The exact penalties would depend on the nature and severity of the breach, as well as the specific provisions of related legislation.
