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 Civil Aviation Safety Authority or its predecessors issued AD/SM-205/21 affecting all SIAI Marchetti S205 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/SM-205/21. The cancellation will become effective on 2 July 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, addressing the need for ensuring the safety and efficiency of air navigation within the country. The Act grants the Governor-General the authority to create regulations in the interest of air navigation safety. Complementing this, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring that these directives are in line with the overarching goal of maintaining aviation safety. This legislative structure allows for the dynamic and responsive management of airworthiness issues as they arise, fulfilling both national and international obligations under the Convention on International Civil Aviation.
The introduction of the Civil Aviation Safety Regulations 1998 was necessitated by the need to formalise and regulate the process of issuing ADs, which are critical for maintaining the continuing airworthiness of aircraft. By allowing CASA to issue these directives, the regulations provide a mechanism for addressing safety issues on a case-by-case basis, ensuring compliance with both national and international standards. The specific regulation in question, AD/SM-205/21, was issued in response to safety concerns related to the SIAI Marchetti S205 model aeroplanes and was subsequently cancelled due to the resolution of those concerns, reflecting the adaptive nature of the regulatory framework.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, which are considered legislative instruments under section 46A of the Acts Interpretation Act 1901. These ADs are integral to maintaining the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design of an aircraft type is responsible for ensuring continuing airworthiness and must provide necessary information to States of Registry, including Australia, where the aircraft are registered. CASA, as Australia’s national airworthiness authority, assesses the information provided by the State of Design and, when appropriate, issues Australian ADs to mandate the necessary requirements. The process of issuing and cancelling ADs, such as the recent cancellation of AD/SM-205/21 for SIAI Marchetti S205 model aeroplanes, is conducted in accordance with the legislative framework and international obligations, without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are legislative instruments, which means they have the force of law and can be subject to disallowance by Parliament (section 46A of the Acts Interpretation Act 1901). Furthermore, these ADs are issued under the authority granted by section 98 of the Civil Aviation Act 1988, with the overarching aim of ensuring the safety of air navigation. The regulation also provides that ADs are a type of disallowable instrument as outlined in the Legislative Instruments Act 2003.
The obligations imposed by these regulations on parties or entities include the State of Design, which has the responsibility of ensuring the continuing airworthiness of an aircraft type and must provide necessary information to appropriate States of Registry (Annex 8 to the Convention on International Civil Aviation). The State of Registry, in this case CASA, must then assess the information provided by the State of Design and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian aircraft meet international safety standards and comply with regulatory requirements.
In terms of penalties and consequences for breach, it is important to note that the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly state penalties for non-compliance with ADs. However, non-compliance with ADs could potentially lead to severe consequences, including the grounding of aircraft, fines, or even criminal charges, depending on the severity of the safety breach. The maximum penalties for breaches of aviation safety regulations can vary but can include significant fines and imprisonment terms, as outlined in other sections of the Civil Aviation Act 1988. It is essential for operators and aircraft owners to comply with ADs to ensure the safety of air navigation and avoid potential legal repercussions.
