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 French DGAC has issued AD F-1993-024 R3 affecting Airbus A320 model aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A320/171, which will become effective on 12 May 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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to establish a comprehensive regulatory framework for civil aviation, focusing on the safety of air navigation. The Act provides the authority for the Governor-General to make regulations that ensure the safety of air navigation, and these regulations are integral to maintaining high standards in the aviation sector. In particular, the Act facilitates the issuing of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998, which are critical for maintaining the continuing airworthiness of aircraft. These ADs are legislative instruments that align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that states adhere to global safety protocols. The objective of this legislative framework is to mandate the continuing airworthiness of aircraft registered in Australia, in alignment with international obligations and standards.
Scope and Application
The Civil Aviation Act 1988 applies to all individuals and entities involved in civil aviation activities within Australia, including aircraft operators, manufacturers, and maintenance organisations. The Act, together with the Civil Aviation Regulations 1998, governs the safety and efficiency of air navigation, including the issuance of airworthiness directives (ADs) under regulation 39.001. ADs, which are legislative instruments, are essential for ensuring the continuing airworthiness of aircraft and aeronautical products. The Civil Aviation (Airworthiness) Regulations 1998 mandate that CASA, Australia’s national airworthiness authority, must issue ADs when necessary, in response to directives from the aircraft's State of Design or other international obligations. This regulatory framework extends to all aircraft registered in Australia and applies nationally, with the aim of harmonising safety standards with those of other ICAO Contracting States. The issuance of ADs is governed by specific regulatory processes and does not require public consultation due to their international and safety-driven nature.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance and enforcement of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General can create regulations aimed at ensuring the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This process is underpinned by the requirement that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties involved are significant. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. In the context of Australian operations, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to enforce the necessary safety measures.
Failure to comply with ADs can lead to severe consequences. The Civil Aviation Act 1988 and associated regulations do not explicitly outline specific offences, penalties, or civil/criminal consequences for non-compliance with ADs. However, the inherent obligation to adhere to ADs is a critical aspect of maintaining aviation safety. Non-compliance can result in significant risks to flight safety, and in extreme cases, could lead to enforcement actions under other sections of the Civil Aviation Act 1988, which may include fines and other penalties. The overarching goal is to ensure that all aircraft operating in Australia meet the necessary safety standards, thereby protecting passengers, crew, and the public.
