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 US FAA has issued AD 2005-13-12 affecting Air Tractor AT-800 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT 800/6, which will become effective on 1 September 2005.
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 was enacted to establish a regulatory framework for civil aviation in Australia, ensuring safety, efficiency, and sustainability in air navigation. This legislation was necessary to address the growing complexity and risks associated with aviation activities, aiming to safeguard the public and maintain orderly growth in the aviation sector. The Act empowers the Governor-General to create regulations that enhance the safety of air navigation, reflecting Australia's commitment to international aviation standards. The Civil Aviation Safety Regulations 1998, which were made under the authority of the Act, further detail the mechanisms for maintaining airworthiness and safety, including the issuance of airworthiness directives (ADs). These ADs serve as a crucial tool for ensuring that aircraft remain in a condition safe for operation, in line with international obligations under the Convention on International Civil Aviation. The Act and its accompanying regulations are pivotal in upholding Australia's responsibilities and commitments to international civil aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, in accordance with section 98 of the Civil Aviation Act 1988. These directives are designed to ensure the safety of air navigation and are legislative instruments as per the Legislative Instruments Act 2003. The issuance of such directives is often in response to international obligations, such as those under Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design. When an AD is issued by a State of Design, CASA must assess the information and, if necessary, issue an Australian AD to enforce the requirements. In the case of the US Federal Aviation Administration (FAA) issuing AD 2005-13-12 for Air Tractor AT-800 model aircraft, CASA assessed the directive and issued Australian AD/AT 800/6, which became effective on 1 September 2005. The AD applies to all entities operating Air Tractor AT-800 model aircraft within Australia and is issued without public consultation, as it is mandated by international obligations and the assessment of relevant State of Design directives.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are mandated to ensure the safety of air navigation, consistent with section 98 of the Civil Aviation Act 1988. Each AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore constitutes a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations require CASA to meticulously assess any airworthiness directives issued by the State of Design, which is the country responsible for the design of the aircraft type. In this context, the State of Registry, which is the country where the aircraft is registered, must ensure the continuing airworthiness of the aircraft. This involves developing or adopting requirements to maintain airworthiness, as stipulated in Annex 8 to the Convention on International Civil Aviation. For instance, if the United States Federal Aviation Administration (FAA) issues an AD for Air Tractor AT-800 model aircraft, CASA, as Australia’s national airworthiness authority, must evaluate this directive and, if deemed necessary, issue a corresponding Australian AD to enforce the required safety measures.
Failing to comply with an airworthiness directive can lead to significant consequences. Non-compliance may result in civil penalties, including fines and other sanctions as prescribed by the Civil Aviation Act 1988. Additionally, there could be criminal penalties if the non-compliance is deemed to endanger safety, potentially resulting in imprisonment. The maximum penalties for such offences are outlined in the relevant sections of the Act, ensuring that there are stringent repercussions for those who do not adhere to the mandated safety requirements. These measures are designed to uphold the highest standards of airworthiness and ensure the safety of all air navigation activities within Australia.
