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 2005-12-14 affecting Boeing 767 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B767/211, which will become effective on 15 July 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 comprehensive framework for the regulation of civil aviation in Australia, focusing on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, and this legislative authority is exercised through the Civil Aviation Safety Regulations 1998. Under these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby playing a crucial role in maintaining the continuing airworthiness of aircraft registered in Australia. These directives are essential tools that align with international standards set forth by the International Civil Aviation Organization (ICAO), ensuring that Australia meets its obligations under the Convention on International Civil Aviation. The ADs, being legislative instruments, are issued without public consultation as they respond to international safety directives, thereby facilitating a consistent and timely approach to aviation safety across the country.
Scope and Application
The Civil Aviation Safety Regulations 1998 under the Civil Aviation Act 1988 provide the regulatory framework within which airworthiness directives (ADs) are issued in Australia. These ADs apply to specified kinds of aircraft or aeronautical products, thereby impacting the entities and persons responsible for the maintenance and operation of these aircraft. The regulations apply to all aircraft registered in Australia, ensuring that the State of Registry adheres to international standards for airworthiness as stipulated in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), acting as Australia's national airworthiness authority, has the responsibility to issue ADs when necessary to mandate the requirements of the State of Design, particularly in response to ADs issued by the aircraft's country of origin. The issuance of ADs is a legislative instrument under Australian law, subject to disallowance and review processes as outlined in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The scope of these ADs is national, as they pertain to the continuing airworthiness of aircraft registered within Australia, and they do not require public consultation or a Regulatory Impact Statement, given their alignment with international obligations and existing regulatory frameworks.
Key Provisions
The Civil Aviation Safety Regulations 1998 under the Civil Aviation Act 1988 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and reviewed under the Legislative Instruments Act 2003. Regulation 39.001(5) specifically clarifies the nature of ADs in this legislative framework. According to Annex 8 of the Convention on International Civil Aviation, the State of Design is responsible for the ongoing airworthiness of an aircraft type and must provide necessary information to the States of Registry to ensure safety. In Australia, CASA, as the national airworthiness authority, assesses such information and, if deemed appropriate, issues Australian ADs to mandate the requirements of the State of Design.
Under these regulations, the State of Registry is tasked with ensuring the continuing airworthiness of individual aircraft, developing or adopting necessary requirements as outlined in Annex 8. For example, the US Federal Aviation Administration (FAA) issued AD 2005-12-14 concerning Boeing 767 model aircraft, with the US being the State of Design. CASA assessed this AD and subsequently issued Australian AD/B767/211, effective from 15 July 2005. Given that this AD stems from Australia’s obligations under the Convention on International Civil Aviation and is in response to an AD from the relevant State of Design, no public consultation was required. Furthermore, the Office of Regulatory Review determined that ADs do not necessitate a Regulatory Impact Statement.
The AD was made by the Manager, Airframes, within CASA's Manufacturing, Certification and New Technologies Office, in accordance with subsection 84A(2) of the Civil Aviation Act 1988. This legal framework places certain obligations on CASA and the State of Registry. CASA must rigorously assess foreign ADs and decide whether to issue corresponding Australian ADs to maintain airworthiness standards. The State of Registry, on the other hand, must implement the requirements set forth in any issued ADs to ensure compliance and safety. Failure to adhere to these ADs can result in serious safety hazards, and non-compliance with airworthiness requirements can lead to severe consequences, including aircraft being grounded or banned from operation.
In terms of penalties and consequences, breaches of the airworthiness directives can have significant ramifications. The Civil Aviation Act 1988 and associated regulations provide for both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can range from fines to imprisonment, depending on the severity of the breach and its impact on aviation safety. For instance, knowingly operating an aircraft that does not comply with an AD can result in substantial fines and, in severe cases, imprisonment. These stringent measures underscore the importance of adhering to airworthiness directives to maintain the highest safety standards in aviation.
