CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 UK CAA issued AD G-2005-0008, affecting Rolls Royce RB211 series engines. The UK is the State of Design for this engine series. As a result of a request from industry, CASA has amended the equivalent Australian AD to AD/RB211/32 Amendment 2. The amended AD, AD/RB211/32 Amendment 2, will become effective on 7 July 2005. This AD cancels and replaces the previous issue.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a legal framework for civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations in the interest of safety, as seen in the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are legislative instruments designed to maintain the continuing airworthiness of aircraft in accordance with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Regulations mandate that CASA, as Australia’s national airworthiness authority, must respond to ADs issued by the State of Design and implement equivalent directives for aircraft registered in Australia. The recent amendment to AD/RB211/32 Amendment 2, in response to a UK Civil Aviation Authority directive, exemplifies the application of these provisions to ensure compliance with international safety standards and obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, specifically the Civil Aviation Safety Regulations 1998, apply to all aircraft and aeronautical products operating within Australia, as well as to the Australian Civil Aviation Authority (CASA) which is tasked with the enforcement and regulation of these provisions. The Act and Regulations mandate that CASA, as Australia’s national airworthiness authority, must issue airworthiness directives (ADs) when necessary to ensure the safety of air navigation. These ADs can apply to specific kinds of aircraft or aeronautical products and are intended to mandate compliance with airworthiness requirements set by the State of Design or as required under international agreements such as Annex 8 to the Convention on International Civil Aviation. The ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. The geographic reach of these regulations is national, applying to all aircraft registered in Australia regardless of where they are designed or manufactured. However, these regulations do not apply to foreign aircraft while they are in Australian airspace unless they are registered in Australia. The ADs themselves are issued in response to specific safety concerns and may be issued without public consultation, particularly when they are mandated by international agreements or in response to directives from the aircraft’s State of Design.
Key Provisions
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, empowers the Australian Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) (sections 98 and 39.001 respectively). ADs are legislative instruments that establish mandatory requirements for maintaining the airworthiness of specific types of aircraft or aeronautical products, ensuring safety in air navigation (section 39.001(5) and section 46A of the Acts Interpretation Act 1901). These directives are integral to the international framework for ensuring the continuing airworthiness of aircraft, as stipulated under Annex 8 to the Convention on International Civil Aviation. Under this framework, the State of Design holds the primary responsibility for the ongoing airworthiness of an aircraft type, providing necessary information to States of Registry to maintain compliance with safety standards. The State of Registry, in turn, is tasked with ensuring the continuing airworthiness of individual aircraft within its jurisdiction, often by issuing or adopting ADs as part of their regulatory requirements.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties such as CASA, the State of Design, and the State of Registry are significant. CASA, as the national airworthiness authority, must meticulously assess information from the State of Design, particularly when it issues an AD that affects aircraft on the Australian Register. Upon assessment, CASA may issue an equivalent Australian AD to ensure compliance with international safety standards. This process ensures that Australian aircraft meet the necessary safety requirements, aligning with international obligations and domestic regulations. The State of Design, in this context, has a responsibility to issue timely and relevant ADs that address identified safety concerns. States of Registry must implement these ADs, ensuring that all aircraft within their jurisdiction adhere to the mandated safety standards.
The implications of failing to comply with ADs under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can be severe. Non-compliance with ADs may lead to significant civil and criminal consequences. Civil penalties can include fines, and in severe cases, criminal penalties may apply. The exact penalties are not specified within the text, but they are intended to enforce adherence to safety standards rigorously. Such enforcement underscores the critical nature of ADs in maintaining the safety and airworthiness of aircraft. The legislative framework ensures that any breaches are met with appropriate legal consequences, reinforcing the importance of compliance with airworthiness directives.
