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 DGAC has issued AD F-2004-038 affecting Airbus Model A319, A320, and A321 aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A320/183, which will become effective on 29 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 was enacted to establish a comprehensive regulatory framework governing civil aviation in Australia, addressing gaps in existing laws to ensure safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations, including those related to airworthiness directives, in the interests of aviation safety. The Civil Aviation Safety Regulations 1998 further support this framework by enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products, aligning with international standards under the Convention on International Civil Aviation. The issuance of these directives is integral to maintaining the continuing airworthiness of aircraft registered in Australia, fulfilling the obligations of the State of Registry as well as the State of Design. The process of issuing such directives is conducted in accordance with the legislative requirements and does not necessitate public consultation or a Regulatory Impact Statement, as it is directly linked to international obligations and assessments by CASA.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a comprehensive framework for ensuring the safety of air navigation in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority is granted by regulation 39.001 of the Civil Aviation Safety Regulations 1998, and these ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. ADs play a crucial role in maintaining the continuing airworthiness of aircraft, with the State of Design having overall responsibility for providing necessary information to States of Registry. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements. For instance, in response to an AD issued by the French Directorate General for Civil Aviation (DGAC) concerning Airbus Model A319, A320, and A321 aircraft, CASA issued Australian AD/A320/183. This process is governed by international obligations under the Convention on International Civil Aviation and does not require public consultation or a Regulatory Impact Statement. The issuance of these ADs is overseen by the Manager, Airframes, within CASA’s Manufacturing, Certification and New Technologies Office, in accordance with the Act’s provisions.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, grants the Governor-General the authority to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. It is crucial to note that under subregulation 39.001(5), ADs are classified as disallowable instruments, as stipulated by section 46A of the Acts Interpretation Act 1901, and are recognised as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations primarily fall on CASA, as the national airworthiness authority. CASA is tasked with assessing any ADs issued by the State of Design—the country where the aircraft type is designed—and, if deemed necessary, issuing corresponding Australian ADs to enforce the design state's requirements. This ensures that all aircraft registered in Australia comply with international safety standards. Additionally, the State of Registry is responsible for the ongoing airworthiness of individual aircraft, and must implement or adopt measures to maintain this airworthiness, as per Annex 8 of the Convention on International Civil Aviation.
Failure to comply with the requirements set out in an AD may result in significant legal consequences. While specific offences and penalties are not detailed in the provided text, non-compliance with ADs generally can lead to enforcement actions by CASA, which might include fines, suspension or revocation of airworthiness certificates, or other regulatory measures. Such actions are intended to enforce adherence to safety standards and protect the public from potential hazards associated with non-compliant aircraft.
Given the international nature of civil aviation, ADs are crucial for maintaining uniform safety standards across jurisdictions. The AD issued by CASA in response to the French State of Design's directive for Airbus A319, A320, and A321 aircraft, exemplifies this cooperative approach. CASA’s assessment and issuance of Australian AD/A320/183 demonstrate the commitment to ensuring that Australian-registered aircraft meet international safety requirements without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
