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 issued AD 88-21-03R1 affecting Boeing 767 aircraft, in 1988. The United States is the State of Design for this aeroplane model. Since that time CASA has issued operation rules which deal with most of the requirements of the subsequent AD that CASA issued. Following review of the Australian AD, AD/B767/29 Amendment 5 will be cancelled and a new AD will be issued dealing only with the relevant parts of AD/B767/29 Amendment 5.
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, New Technologies and Systems, 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 legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety, efficiency, and orderly development of air transport. The Act was brought into law by the Australian Parliament and aims to safeguard public safety, facilitate the growth of the aviation industry, and manage the environmental impacts of aviation. The Civil Aviation (Safety) Regulations 1998 further detail the specific procedures and requirements under the Act, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations empower CASA to issue ADs in the interests of air navigation safety and are made in accordance with the authority granted under section 98 of the Civil Aviation Act 1988. The ADs are designed to address identified safety issues with aircraft or aeronautical products and are mandated by international aviation standards set by the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory mechanism is integral to ensuring the safety of air navigation across Australia, reflecting the overarching responsibility of the State of Design to maintain the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue corresponding Australian ADs in response to directives from the State of Design, thereby harmonising with international obligations under the Convention on International Civil Aviation. The issuance of ADs is governed by Annex 8, which stipulates that the State of Registry is responsible for the continuing airworthiness of individual aircraft. Notably, ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, and as such, they do not require public consultation or a Regulatory Impact Statement. The process of issuing these directives is managed by CASA, reflecting its role in implementing safety measures in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to enact regulations for the Act, focusing on the safety of air navigation. According to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. An airworthiness directive is essentially a formal notification to aircraft operators or manufacturers regarding safety concerns and the required actions to address these issues.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design bears the primary responsibility for the continuing airworthiness of an aircraft type. This includes providing all necessary information to ensure the ongoing airworthiness of the type to appropriate States of Registry. ADs are the primary method through which this information is communicated and are issued by most International Civil Aviation Organization (ICAO) Contracting States. In Australia, the State of Registry is responsible for the continuing airworthiness of individual aircraft. Under Annex 8, this state must establish or adopt requirements to ensure the ongoing airworthiness of aircraft. When a State of Design, such as the United States for Boeing 767 aircraft, issues an AD, CASA, as Australia’s national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the State of Design’s requirements.
The obligations imposed by these regulations are significant for all parties involved. The State of Design must ensure that the necessary information is communicated promptly to States of Registry, and that the ADs issued are based on sound safety principles. States of Registry, including Australia, must implement and enforce the ADs to maintain the airworthiness of aircraft within their jurisdiction. CASA, as the enforcing authority, must carefully review the information provided by the State of Design and issue Australian ADs as needed. Aircraft operators and manufacturers are required to comply with these ADs to ensure the safety of their operations.
Failure to comply with the ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to civil penalties, including fines and potential legal action. The specific penalties depend on the severity of the non-compliance and may vary based on individual circumstances. Additionally, continued non-compliance could result in the grounding of affected aircraft, further impacting operations and safety. The regulatory framework is designed to ensure that all parties adhere strictly to the ADs to maintain the highest safety standards in aviation.
