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 EASA has issued AD 2006-0344 R1 affecting Eurocopter EC 130 B4 model aircraft. The EASA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ECUREUIL/122, Amendment 1, which will become effective on 5 July 2007. This AD cancels and replaces the previous issue.
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, New Technologies and Systems, 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, addresses the regulation and safety of civil aviation within Australia. This legislation was introduced to ensure the safety of air navigation and establish a regulatory framework for civil aviation activities, including the oversight of aircraft airworthiness. Under the authority granted by section 98 of the Act, the Civil Aviation Safety Regulations 1998 were established to further detail the requirements for maintaining airworthiness, among other safety regulations. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which serve as a crucial mechanism for ensuring the continuing airworthiness of aircraft. This regulatory approach aligns with Australia's commitments under the Convention on International Civil Aviation, ensuring that national aviation safety standards are harmonised with international obligations. The issuance of specific airworthiness directives, such as AD/ECUREUIL/122, Amendment 1, reflects CASA's role in implementing necessary safety measures in response to international directives, thereby maintaining the safety and integrity of Australia's civil aviation system.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) for aircraft and aeronautical products in Australia. The Act empowers the Governor-General to make regulations in the interests of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs. These ADs are considered legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs are necessary to ensure the continuing airworthiness of aircraft and are issued in compliance with Annex 8 to the Convention on International Civil Aviation, which places the responsibility for airworthiness on the State of Design and the State of Registry. CASA, as Australia’s national airworthiness authority, must evaluate and, if necessary, issue Australian ADs in response to directives from the relevant State of Design. This process ensures that Australian aviation aligns with international standards and obligations.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for issuing airworthiness directives (ADs) (sections 98 and 39.001). An AD, as defined in regulation 39.001(5), is a legislative instrument that mandates specific actions to ensure the continuing airworthiness of aircraft or aeronautical products. These directives are issued by the Civil Aviation Safety Authority (CASA) and are designed to align with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case the European Aviation Safety Agency (EASA), has the primary responsibility for ensuring the continuing airworthiness of aircraft types, and CASA, as Australia’s national airworthiness authority, must assess and implement these directives as appropriate.
The obligations imposed by the Civil Aviation Act and the Civil Aviation Safety Regulations on parties governed by these laws include the requirement for the State of Design to provide necessary information to ensure the airworthiness of aircraft types (Annex 8). CASA must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian-registered aircraft comply with international safety standards. For example, EASA's AD 2006-0344 R1 concerning the Eurocopter EC 130 B4 model was assessed and subsequently implemented by CASA as AD/ECUREUIL/122, Amendment 1, effective from 5 July 2007.
Failure to comply with ADs can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in various civil and criminal penalties. The maximum penalties for breaches include fines and imprisonment, reflecting the critical nature of adhering to airworthiness directives. CASA, as the enforcing body, has the authority to take action against entities that fail to comply with these regulations, ensuring that the safety standards are upheld within the aviation sector. The issuing of ADs and the enforcement of compliance are vital to maintaining the safety and integrity of air navigation in Australia and internationally.
