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/RRP-C/2 affecting Rolls Royce (Blackburn) Cirrus series engines. CASA has assessed this AD and as a result has cancelled Australian AD/RRP-C/2. The cancellation will become effective on 2 July 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 robust legal framework governing civil aviation safety in Australia. This Act empowers the Governor-General to create regulations that ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998, which were also introduced under the authority of the Civil Aviation Act 1988, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products. These ADs, which are considered legislative instruments, are instrumental in maintaining the continuing airworthiness of aircraft, aligning with international standards as outlined in Annex 8 of the Convention on International Civil Aviation. This legislative framework ensures that both the State of Design and the State of Registry have clearly defined responsibilities, with CASA acting as the national airworthiness authority to enforce these standards domestically.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) responsible for ensuring the continuing airworthiness of aircraft on the Australian Register. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products. These directives, which are considered legislative instruments under the Legislative Instruments Act 2003, are a common means of continuing airworthiness information as per Annex 8 to the Convention on International Civil Aviation. The State of Design of an aircraft has the primary responsibility for ensuring continuing airworthiness and must provide necessary information to the States of Registry, which must then implement these requirements. In the instance of AD/RRP-C/2 concerning Rolls Royce (Blackburn) Cirrus series engines, CASA cancelled the Australian AD after assessing the information from the State of Design and determining that the unsafe condition no longer existed, thus no longer necessitating the directive. The cancellation of this AD, aligning with Australia's international obligations, did 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 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act empowers the Governor-General to make regulations that contribute to the safety of air navigation, and regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legislative instruments, as defined in section 6 of the Legislative Instruments Act 2003.
Under the Civil Aviation Safety Regulations 1998, CASA is mandated to issue ADs for aircraft or aeronautical products on the Australian Register when necessary to ensure their continuing airworthiness. This is in line with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design has overall responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must ensure the continuing airworthiness of individual aircraft. In this context, when a State of Design issues an AD, CASA must assess the information and, if deemed necessary, issue an Australian AD to mandate the requirements of the State of Design.
The obligations imposed by the Act and the Regulations on the parties involved are stringent and focus on maintaining the highest safety standards. CASA, as the national airworthiness authority, must rigorously evaluate ADs issued by States of Design and determine whether these require an Australian AD. If a directive is issued, it must be communicated effectively to all relevant stakeholders, including aircraft operators and maintenance providers. These stakeholders are then required to comply with the ADs within specified timeframes to ensure that the safety measures are implemented promptly and effectively.
Failure to comply with ADs can lead to significant legal consequences. Section 94 of the Civil Aviation Act 1988 imposes penalties for non-compliance with ADs. The penalties can include substantial fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, with maximum penalties specified in the relevant sections of the Act. Additionally, CASA has the authority to take enforcement actions, such as grounding aircraft that do not comply with ADs, to prevent any potential safety risks. The enforcement actions are designed to ensure that all parties adhere strictly to the safety regulations, thereby maintaining the overall safety of air navigation.
