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-2004-028 R2 affecting Airbus A330 model aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A330/104, which will become effective on 27 August 2009.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, providing a comprehensive framework for the safe operation of aircraft. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, as seen in the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. An AD is a legislative instrument designed to ensure the continuing airworthiness of aircraft, mandated by the State of Design and enforced by the State of Registry. The Civil Aviation Safety Authority (CASA) issues these directives in response to international obligations under the Convention on International Civil Aviation, specifically Annex 8, which places the responsibility of continuing airworthiness on the State of Design. For instance, in response to an AD issued by France for Airbus A330 model aircraft, CASA has issued its own directive, effective from 27 August 2009, reflecting its duty to ensure compliance with international safety standards.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, which fall under the purview of the Civil Aviation Act 1988, pertain to the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These regulations apply to all aircraft registered in Australia and other aeronautical products, ensuring compliance with safety standards for air navigation. The issuance of airworthiness directives is governed by regulation 39.001, which empowers CASA to issue these directives for specific types of aircraft or aeronautical products. These directives are considered legislative instruments under the Legislative Instruments Act 2003. The application of these regulations is international in scope, aligning with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design maintains responsibility for the continuing airworthiness of aircraft types and must share necessary information with the States of Registry. In practice, this means that when a State of Design issues an airworthiness directive, CASA must evaluate this information and, if necessary, issue a corresponding Australian airworthiness directive. This process ensures that Australian-registered aircraft meet international safety standards. Exemptions and exclusions are not specified in the regulations; however, the issuance of airworthiness directives is directly tied to international obligations and assessments by CASA.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, grants the Governor-General the authority to establish regulations that align with the Act and prioritise the safety of air navigation. This broad mandate enables the creation of specific rules and directives, such as airworthiness directives (ADs), which are vital for maintaining the safety standards of aircraft. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further clarifies that the Civil Aviation Safety Authority (CASA) has the power to issue ADs for certain types of aircraft or aeronautical products. These directives are crucial as they mandate specific actions to ensure the continuing airworthiness of aircraft, aligning with international standards and obligations.
The obligations imposed by these ADs are significant for both CASA and the operators of affected aircraft. CASA, as Australia's national airworthiness authority, is tasked with assessing international ADs, such as the one issued by the French DGAC for Airbus A330 model aircraft. Once an assessment is made, CASA may issue a corresponding Australian AD, as seen with AD/A330/104. Operators of affected aircraft must comply with these directives to ensure their aircraft meet the required safety standards. This involves implementing any necessary modifications, inspections, or maintenance actions specified in the ADs, thereby ensuring that the aircraft remain airworthy and compliant with international aviation safety standards.
The Civil Aviation Safety Regulations 1998 outline the consequences for non-compliance with airworthiness directives. While specific penalties are not detailed within the provided text, it is clear that breaches of these regulations could lead to severe consequences. Failure to comply with an AD can result in the aircraft being deemed unairworthy, which can lead to grounding of the aircraft and potential legal action against the operator. Additionally, CASA has the authority to take enforcement actions, which could include fines or other penalties, as stipulated by the overarching aviation regulations and safety standards. The seriousness of these potential consequences underscores the importance of strict adherence to ADs by all relevant parties.
