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 European Aviation Safety Authority (EASA) has issued AD 2008-0127R1 affecting Saab SF340A and 340B model aircraft. The EASA acts on behalf of Sweden, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/SF340/107, Amendment 1, which will become effective on 25 September 2008. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, Systems and New Technologies in the Airworthiness EngineeringGroup, 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 overarching need for aviation safety and regulation within Australia. This Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation, reflecting the government's commitment to maintaining high standards of aviation safety. Under the Act, the Civil Aviation Safety Regulations 1998 were established, granting the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a critical tool for maintaining the continuing airworthiness of aircraft, in line with international standards set by the Convention on International Civil Aviation. The ADs issued under this framework are designed to ensure compliance with both national and international obligations, facilitating a coordinated approach to aviation safety across different jurisdictions.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, being legislative instruments, are designed to enforce necessary modifications or inspections to maintain airworthiness. This regulatory approach applies to all aircraft registered in Australia and extends to ensuring compliance with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The responsibility for continuing airworthiness falls on the State of Registry, with CASA as Australia's national airworthiness authority mandated to issue corresponding ADs when required. For instance, in response to an AD issued by the European Aviation Safety Authority for Saab SF340A and 340B model aircraft, CASA has issued its own AD, AD/SF340/107, Amendment 1, which becomes effective on 25 September 2008. This directive, issued under Australia’s obligations under the Convention on International Civil Aviation, does not require public consultation or a Regulatory Impact Statement, reflecting its compliance with international obligations and safety imperatives.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Regulation 39.001(5) clarifies that ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and are thus legislative instruments as per the Legislative Instruments Act 2003. This means that while ADs are regulatory measures, they carry the weight of formal legislation and can be subject to disallowance by Parliament. Furthermore, the ADs issued by CASA are in response to international obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as the entity responsible for the continuing airworthiness of an aircraft type. CASA’s role, as Australia’s national airworthiness authority, involves assessing these international directives and, if necessary, issuing corresponding Australian ADs to ensure compliance and safety within Australia’s aviation sector.
The obligations imposed on parties and entities governed by these regulations are multifaceted. Firstly, CASA must rigorously assess any ADs issued by the State of Design, particularly those that pertain to aircraft types registered in Australia. This involves ensuring that the proposed safety measures are appropriate and can be effectively implemented within the Australian context. Secondly, the State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must adopt and enforce the requirements set forth in the ADs. This includes ensuring that all aircraft operators are notified of the ADs and that the necessary actions are taken to comply with the mandated safety measures. Additionally, aircraft operators are obligated to follow the instructions and timelines provided in the ADs, ensuring that their aircraft meet the required airworthiness standards.
Any breach of the provisions set forth in the Civil Aviation Safety Regulations 1998, including non-compliance with ADs, can lead to serious consequences. Civil penalties may be imposed for minor infractions, such as failure to adhere to specified deadlines or incomplete compliance with the ADs. The maximum civil penalty for each day of non-compliance is set at a substantial amount, reflecting the importance of air safety. In more severe cases, criminal penalties may apply, especially if the breach results in significant safety risks or incidents. Such criminal penalties can include fines and, in extreme cases, imprisonment, depending on the severity and impact of the breach. These stringent measures underscore the critical nature of adhering to airworthiness directives and the serious repercussions of failing to do so.
