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 Swiss FOCA has issued AD HB-2007-295 affecting Swiss Air Ambulance Ltd Horizontal Rescue Nets. Switzerland is the State of Design for this equipment. CASA has assessed this AD and has issued Australian AD/RES/34, which will become effective on 25 October 2007.
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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, serves as a foundational statute governing civil aviation safety within the country. It was introduced to address the need for comprehensive regulation of civil aviation operations and to ensure the safety of air navigation, among other objectives. One of the key mechanisms through which this is achieved is via the issuance of airworthiness directives (ADs), as outlined in the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to mandate safety requirements for aircraft and aeronautical products, reflecting Australia’s commitment to international standards under the Convention on International Civil Aviation. The legislative framework ensures that CASA, as the national airworthiness authority, can effectively manage the continuing airworthiness of aircraft registered in Australia, particularly in response to directives issued by the aircraft’s State of Design.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides a legislative framework for ensuring the safety of air navigation in Australia, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products, with these ADs being classified as disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. The ADs are integral to fulfilling Australia’s obligations under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type, and the State of Registry is responsible for ensuring the continuing airworthiness of individual aircraft. When a State of Design, such as Switzerland in this instance, issues an AD, CASA must evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the required safety measures on aircraft registered in Australia. The issuance of Australian AD/RES/34, in response to the Swiss FOCA’s AD HB-2007-295, exemplifies this process, illustrating the interconnectedness of international civil aviation regulations and the domestic application of ADs within Australia.
Key Provisions
The Civil Aviation (Safety) Regulations 1998 provide the regulatory framework for the issuance of airworthiness directives (ADs) under section 39.001 of the Civil Aviation Safety Regulations 1998. These directives are issued by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft and aeronautical products. Under regulation 39.001(5), an AD is considered a disallowable instrument under the Acts Interpretation Act 1901 and is thus a legislative instrument. This means that ADs carry the weight of law and must be followed by the parties they govern. The ADs are typically issued in response to safety concerns identified in the aircraft design or operational processes, and are a fundamental tool for ensuring that aircraft meet the required safety standards.
Obligations imposed by the Act on the parties governed by the AD include compliance with the requirements specified in the directive. For example, if an AD mandates certain modifications to an aircraft, the owner or operator of the aircraft must ensure that these modifications are carried out within the specified timeframe. Additionally, the State of Registry, which is responsible for the continuing airworthiness of an individual aircraft, must ensure that all ADs applicable to aircraft on the Australian Register are complied with. This includes implementing the requirements specified in ADs issued by the State of Design, such as Switzerland in the case of AD/RES/34.
The Act also outlines the consequences of failing to comply with an AD. Breaches of an AD can lead to significant civil and criminal penalties. Under section 98 of the Civil Aviation Act 1988, non-compliance with an AD can result in penalties up to $504,000 for individuals and $2,520,000 for corporations. In addition to financial penalties, non-compliance can also result in operational restrictions or the grounding of the aircraft in question. Furthermore, CASA has the authority to take enforcement actions, including issuing fines, directing the grounding of non-compliant aircraft, and even prosecuting individuals or corporations for serious breaches. These measures underscore the importance of adhering to ADs to maintain the highest standards of aviation safety.
