CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 Emergency ADs UF-2005-102 and UF-2005-103 affecting AS 350 Ecureuil and EC 130 model aircraft. France is the State of Design for these types. CASA has assessed these ADs and has issued Australian AD/ECUREUIL/112, covering both types, which will become effective on 20 June 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 Section Head - Airframes Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive regulatory framework governing civil aviation in Australia, ensuring the safety and efficiency of air navigation and related activities. Under this Act, the Civil Aviation Safety Regulations 1998 were introduced, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments, ensuring compliance with international standards and obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The objective of this regulatory framework is to uphold the highest safety standards in civil aviation, aligning with international protocols and maintaining the continuing airworthiness of aircraft registered in Australia. CASA, as the national airworthiness authority, is mandated to assess and, when necessary, issue Australian ADs in response to directives from the relevant State of Design, such as the French DGAC’s Emergency ADs affecting AS 350 Ecureuil and EC 130 model aircraft. This process ensures that Australia meets its international obligations and maintains the safety of its aviation fleet.
Scope and Application
The Civil Aviation Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Governor-General to make regulations that ensure the safety of air navigation. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. These ADs are legislative instruments, as outlined in subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901, and are subject to disallowance under the Legislative Instruments Act 2003. The application of ADs is dictated by international standards, particularly Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to ensure the continuing airworthiness of aircraft types and provide necessary information to States of Registry, including Australia. CASA, as the national airworthiness authority for Australia, is obligated to assess such information and, if necessary, issue Australian ADs to enforce the requirements set forth by the State of Design. For instance, in response to French emergency ADs affecting AS 350 Ecureuil and EC 130 model aircraft, CASA issued Australian AD/ECUREUIL/112, which became effective on 20 June 2005. Given the international nature of these directives and Australia's obligations under the Convention, no public consultation was conducted, and a Regulatory Impact Statement was deemed unnecessary by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, outlines the process for issuing airworthiness directives (ADs) to ensure the safety of air navigation. According to section 98 of the Act, the Governor-General can make regulations for the safety of air navigation, and regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) stipulates that an AD is a disallowable instrument, making it a legislative instrument under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that ADs are a formal mechanism for maintaining the airworthiness of aircraft.
The obligations imposed by this legislation primarily fall on CASA, as Australia’s national airworthiness authority. Under Annex 8 to the Convention on International Civil Aviation, CASA is tasked with assessing ADs issued by the State of Design and, where necessary, issuing corresponding Australian ADs. This ensures that any airworthiness concerns identified by the State of Design are appropriately addressed within the Australian aviation system. Additionally, CASA must ensure that the State of Registry, which is responsible for the individual aircraft’s continuing airworthiness, develops or adopts the necessary requirements to maintain airworthiness.
Failing to comply with an airworthiness directive can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in enforcement actions by CASA. This can include penalties for civil aviation offences, which may involve fines and other sanctions. The severity of the penalties depends on the nature and extent of the non-compliance, but they are designed to ensure that all aircraft meet the necessary safety standards. Additionally, persistent non-compliance may result in criminal charges, leading to more severe penalties including imprisonment.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for issuing and enforcing airworthiness directives to maintain the safety of air navigation. CASA’s role is pivotal in ensuring that ADs issued by the State of Design are effectively implemented in Australia. Failure to comply with these directives can result in significant civil and criminal penalties, thereby ensuring that all stakeholders adhere to the highest safety standards.
