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 Transport Canada has issued AD CF-2004-11 affecting Bombardier DHC-8-400 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/107, which will become effective on 16 March 2006.
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, enacted by the Parliament of Australia, aims to ensure the safety of air navigation and the regulation of civil aviation within Australia. It provides the legislative framework under which the Civil Aviation Safety Regulations 1998 are made, which in turn enable the issuance of airworthiness directives. Regulation 39.001 of the Civil Aviation Safety Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments that mandate safety requirements for aircraft and aeronautical products. This mechanism is integral to maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design is responsible for the ongoing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. In the case of Bombardier DHC-8-400 model aircraft, CASA has issued an Australian airworthiness directive in response to an airworthiness directive issued by Transport Canada, reflecting Australia's obligations under international conventions and ensuring the safety and compliance of aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, authorises the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation in Australia. These directives apply to types of aircraft and aeronautical products registered in Australia, thereby imposing obligations on aircraft owners, operators, and maintenance providers to comply with safety standards. ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and are made pursuant to Australia's obligations under the Convention on International Civil Aviation. When a State of Design issues an AD, CASA must assess and, if necessary, issue an Australian AD to enforce the requirements domestically. This process ensures that Australian aircraft meet international safety standards. The AD in question, issued in response to Transport Canada’s AD CF-2004-11, pertains to Bombardier DHC-8-400 model aircraft and is an example of how CASA implements international safety directives within its jurisdiction. The issuance of this AD did not require public consultation, and no Regulatory Impact Statement was deemed necessary by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, allows the Governor-General to make regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments as per section 6 of the Legislative Instruments Act 2003, and they are disallowable under section 46A of the Acts Interpretation Act 1901. ADs are essential for maintaining the continuing airworthiness of aircraft and are typically issued by the State of Design, which must provide necessary information to the State of Registry. In this case, Canada, as the State of Design for the Bombardier DHC-8-400 model, has issued AD CF-2004-11. CASA, as Australia’s national airworthiness authority, has assessed this directive and issued an Australian AD, AD/DHC-8/107, to ensure compliance with the requirements specified by Canada.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and other entities include the assessment and implementation of ADs issued by the State of Design. CASA must ensure that all aircraft registered in Australia comply with ADs relevant to their type. This involves evaluating the ADs issued by other States of Design and determining whether Australian ADs are necessary. The State of Registry is also obligated to develop or adopt requirements to ensure the continuing airworthiness of aircraft. Additionally, under Annex 8 of the Convention on International Civil Aviation, the State of Design has the responsibility to provide necessary information to maintain the airworthiness of aircraft types, which CASA then uses to issue corresponding ADs for Australian-registered aircraft.
Breaching the requirements set out in the ADs can lead to significant legal consequences. The Civil Aviation Act 1988 and associated regulations establish that failure to comply with an AD can result in the aircraft being deemed unairworthy. This can lead to enforcement actions by CASA, which may include grounding the aircraft until compliance is achieved. Non-compliance with ADs is a serious matter as it directly impacts the safety of air navigation. While specific penalties are not detailed in the provided text, it is clear that CASA has the authority to take enforcement actions to ensure adherence to airworthiness standards.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for issuing and enforcing airworthiness directives. CASA’s role in assessing and implementing these directives is crucial for maintaining the safety and airworthiness of aircraft registered in Australia. The obligations placed on CASA and other entities ensure that aircraft continue to meet necessary safety standards, and non-compliance with ADs can result in serious legal and operational consequences.
