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 French DGAC has issued AD F-2005-094 affecting Eurocopter Super Puma helicopters. France is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/S-PUMA/61, which will become effective on 1 September 2005.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes a comprehensive framework for the regulation of civil aviation within Australia. This legislation aims to ensure the safety and efficiency of civil aviation operations, with a particular emphasis on the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were also created to provide further detail on how the Act's provisions are to be implemented. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products to maintain the safety and airworthiness standards. The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, allow CASA to issue such directives, which are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are crucial in adhering to Australia's international obligations under the Convention on International Civil Aviation, ensuring the continuing airworthiness of aircraft as mandated by the State of Design and the State of Registry.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, under which the Civil Aviation Safety Authority (CASA) can mandate requirements for the continuing airworthiness of aircraft types registered in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue ADs for particular kinds of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. This authority is exercised in compliance with Australia’s international obligations under the Convention on International Civil Aviation, specifically Annex 8, which delineates the responsibilities of the State of Design and the State of Registry concerning the continuing airworthiness of aircraft types. When an AD is issued by the State of Design, CASA, as Australia's national airworthiness authority, is required to evaluate the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian registered aircraft meet international safety standards. The process does not involve public consultation, as it is governed by international obligations and CASA's duty to uphold air safety.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, facilitate the issuance of airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation. Regulation 39.001 of the 1998 Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and hence as legislative instruments according to section 6 of the Legislative Instruments Act 2003.
These provisions establish a framework where CASA, as the national airworthiness authority, has the responsibility to assess ADs issued by the State of Design and to mandate equivalent requirements within Australia if necessary. This ensures that Australian aircraft maintain their airworthiness in accordance with international standards and obligations under the Convention on International Civil Aviation, particularly Annex 8, which outlines the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia, thereby aligning with international standards and directives.
The obligations imposed on the parties governed by these provisions are significant. The State of Design, such as France for the Eurocopter Super Puma helicopters, is responsible for issuing ADs that address safety concerns and ensure the continuing airworthiness of the aircraft type. CASA, as the State of Registry for Australian-registered aircraft, must rigorously assess these ADs and issue corresponding Australian ADs when necessary. This involves evaluating the information provided by the State of Design and determining its applicability to aircraft on the Australian Register. Additionally, CASA must ensure that all ADs issued are compliant with international conventions and adequately address any identified safety issues.
There are specific consequences for breaches of these obligations. While the Act and Regulations do not detail specific civil or criminal penalties for failing to comply with ADs, non-compliance can result in severe consequences, including the grounding of aircraft, potential safety incidents, and legal actions against both manufacturers and operators. The issuance of ADs is governed by stringent international and national regulations designed to prevent such breaches, ensuring that all stakeholders adhere to the highest safety standards. The seriousness of these obligations underscores the critical importance of compliance in maintaining the safety and integrity of air navigation.
