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-300 and AT-400 model aircraft. The USA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/AT/26, 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 provide a legislative framework for the regulation of civil aviation in Australia, addressing the need for a cohesive and comprehensive approach to air navigation safety and oversight. This Act empowers the Governor-General to make regulations for the purposes of ensuring the safety of air navigation, thereby providing a robust foundation for the regulation of civil aviation activities within Australia. The Civil Aviation Safety Regulations 1998, made under the authority of the Civil Aviation Act 1988, further detail the requirements for airworthiness directives (ADs) and other regulatory measures. These regulations facilitate the issuance of ADs by the Civil Aviation Safety Authority (CASA) to maintain the continuing airworthiness of aircraft and aeronautical products. The policy objective underpinning these legislative measures is to uphold the highest standards of aviation safety, in alignment with Australia's international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 applies to all persons, entities, and industries involved in civil aviation within Australia, with a particular focus on ensuring the safety of air navigation. Under the Act, the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) that mandate the continuing airworthiness of aircraft types. These regulations allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products to ensure safety standards are met. These directives are considered legislative instruments under the Legislative Instruments Act 2003 and are often issued in response to airworthiness concerns raised by the State of Design, such as the United States Federal Aviation Administration (FAA). The ADs are typically made without public consultation as they are in response to international obligations under the Convention on International Civil Aviation. The ADs become effective as mandated by CASA, ensuring that the requirements set forth by the State of Design are adopted and enforced within Australia.
Key Provisions
The Civil Aviation Act 1988 allows the Governor-General to create regulations for the safety of air navigation, and under section 98, the Civil Aviation Safety Regulations 1998 empower CASA to issue airworthiness directives (ADs) for specific aircraft or aeronautical products (section 39.001). These ADs are considered legislative instruments and must comply with the Legislative Instruments Act 2003 (section 46A of the Acts Interpretation Act 1901). According to Annex 8 of the Convention on International Civil Aviation, the State of Design bears the responsibility for the ongoing airworthiness of an aircraft type, and must provide necessary information to the State of Registry to ensure this. The State of Registry, in turn, must establish requirements to maintain the airworthiness of the aircraft. When an AD is issued by a State of Design, CASA must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed by these regulations are multifaceted. The State of Design must ensure the ongoing airworthiness of their aircraft types and communicate necessary information to the relevant States of Registry. States of Registry must develop or adopt requirements to maintain airworthiness and comply with ADs issued by the State of Design. CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue Australian ADs to mandate the requirements of foreign ADs. This ensures that Australian aircraft meet international safety standards. Furthermore, the Manager, Airframes in the Manufacturing, Certification and New Technologies Office is responsible for making these ADs on behalf of CASA, following the procedures outlined in the Act (subsection 84A(2)).
Failure to comply with these obligations can result in significant legal consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide for various offences and penalties for non-compliance. For instance, operating an aircraft that does not meet the airworthiness standards set by ADs can result in hefty fines and imprisonment. The specific penalties vary depending on the severity of the breach and are determined by the relevant courts. Additionally, CASA can impose administrative penalties for non-compliance, which can include fines and other corrective measures. These provisions underscore the importance of adhering to airworthiness directives to ensure the safety of air navigation.
