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 United States FAA has issued AD 2008-24-51 affecting Boeing model 737 aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/347, which will become effective on 20 November 2008.
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, Systems and New Technologies in the Airworthiness Engineering Group, 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, governs civil aviation safety in the country. It empowers the Governor-General to make regulations for the safety of air navigation, with specific provisions allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft or aeronautical products. This legislation was introduced to address the need for stringent oversight and compliance in maintaining the airworthiness of aircraft operating in Australia, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further specify the processes and requirements for issuing these directives. These regulations ensure that CASA, as the national airworthiness authority, can effectively respond to safety concerns by issuing directives that mandate necessary actions to maintain the safety standards of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) within Australia, ensuring the safety of air navigation. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These directives are legislative instruments, as they are disallowable under the Acts Interpretation Act 1901 and subject to the Legislative Instruments Act 2003. The ADs are primarily aimed at maintaining the continuing airworthiness of aircraft as required under Annex 8 to the Convention on International Civil Aviation, with the State of Design having overarching responsibility for airworthiness, and the State of Registry ensuring compliance with local requirements. CASA, acting on Australia’s obligations under international conventions, assesses and issues Australian ADs in response to ADs issued by the relevant State of Design. For example, CASA issued AD/B737/347 in response to the U.S. Federal Aviation Administration’s AD 2008-24-51 for Boeing model 737 aircraft. These ADs do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, under section 98, grants the Governor-General the authority to make regulations that are in the interests of air navigation safety. In line with this provision, 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. An AD, as defined in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and, therefore, falls under the purview of the Legislative Instruments Act 2003 as a legislative instrument. ADs play a pivotal role in ensuring the continuing airworthiness of aircraft types, with the State of Design having the overarching responsibility to provide necessary information to States of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation.
The Civil Aviation Safety Regulations 1998 mandate that the State of Registry of an individual aircraft is responsible for its continuing airworthiness. This obligation requires States of Registry to develop or adopt requirements to ensure that aircraft remain airworthy. When the State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate the information and, if deemed appropriate, issue an Australian AD to enforce the requirements set by the State of Design. This process ensures that Australian aircraft comply with international standards and recommendations. In the case of AD 2008-24-51 issued by the United States Federal Aviation Administration (FAA) for Boeing model 737 aircraft, CASA has assessed the directive and issued Australian AD/B737/347, effective from 20 November 2008. This directive is a direct response to Australia’s obligations under the Convention on International Civil Aviation and the AD issued by the relevant State of Design, thus no public consultation was required.
Breaching the requirements set forth in an airworthiness directive can lead to significant consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can result in severe penalties, including substantial fines and potential criminal charges. The specific penalties depend on the nature and severity of the breach, with maximum penalties outlined in the Act. Such breaches not only endanger the safety of air navigation but also undermine the regulatory framework designed to protect public safety and ensure the continued airworthiness of aircraft. The enforcement of ADs is critical in maintaining the high safety standards expected in the aviation industry.
