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-2005-165 affecting Airbus A320 aeroplanes. France is the State of Design for this aeroplane model. CASA has assessed this AD and as a result has cancelled Australian AD/A320/150. The cancellation will become effective on 22 December 2005. No replacement AD is required, as the original unsafe condition has been corrected by incorporating the procedure into the aircraft flight manual.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. 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 is the foundational legislation governing civil aviation in Australia, enacted to ensure the safety and efficiency of civil aviation within Australia and its territories. This Act was developed to address the need for a comprehensive regulatory framework that would govern the safety and operational aspects of civil aviation, aligning with international standards and obligations, particularly those set forth by the International Civil Aviation Organization (ICAO). The Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, with the Civil Aviation Safety Regulations 1998 being a key set of regulations established under this authority. The Civil Aviation Safety Regulations 1998 were introduced to further delineate specific safety standards and requirements for aircraft and aeronautical products, thereby enhancing the enforcement of airworthiness directives (ADs). These ADs, as specified in regulation 39.001, are legislative instruments that are crucial for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry. The Civil Aviation Safety Authority (CASA), as Australia’s national airworthiness authority, plays a pivotal role in assessing and issuing these directives to ensure compliance with both domestic and international safety standards.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure their continuing airworthiness. These directives are considered legislative instruments, subject to disallowance and review as stipulated in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs are integral to compliance with Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design—the country where an aircraft type is designed—must provide necessary information for maintaining airworthiness, which the State of Registry (the country where the aircraft is registered) must implement. In Australia, CASA, as the national airworthiness authority, assesses ADs issued by the State of Design and, when necessary, issues corresponding Australian ADs. For example, CASA assessed and subsequently cancelled an Australian AD for Airbus A320 aeroplanes following an AD issued by the French DGAC, as France is the State of Design for this model. This cancellation was made without public consultation or a Regulatory Impact Statement, reflecting CASA’s adherence to international obligations and the nature of ADs as technical mandates rather than broad policy instruments.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for ensuring the safety of air navigation in Australia. Section 98 of the Act empowers the Governor-General to make regulations for the Act's purposes, specifically focusing on the safety of air navigation, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified aircraft types or aeronautical products. The ADs serve as a legislative instrument, disallowable under section 46A of the Acts Interpretation Act 1901 and regulated as a legislative instrument under the Legislative Instruments Act 2003.
The obligations and requirements imposed by these provisions on parties or entities, particularly CASA, involve ensuring the continuing airworthiness of aircraft registered in Australia. CASA must assess ADs issued by the State of Design, such as the French DGAC's AD F-2005-165 concerning Airbus A320 aeroplanes, and determine if an Australian AD is necessary. In this instance, CASA cancelled Australian AD/A320/150 in response to the French AD, ensuring that the aircraft's safety requirements align with international standards. This process underscores the need for CASA to stay informed of international airworthiness directives and adapt them to the Australian context when necessary.
In terms of compliance and consequences, breaches of these regulations could lead to serious safety issues, although the specific offences, penalties, or civil/criminal consequences are not detailed in the provided text. However, the importance of adhering to ADs cannot be overstated, as they are fundamental to maintaining the safety standards required under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Non-compliance with these regulations could result in enforcement actions by CASA, which might include fines, grounding of aircraft, or other regulatory sanctions. These measures ensure that all parties involved maintain the highest standards of airworthiness, protecting both the public and the integrity of the aviation industry.
