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 European Aviation Safety Authority (EASA) has issued AD 2007-0295-E affecting Agusta A109 model helicopters. EASA acts on behalf of Italy, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A109/60, which will become effective on 04 December 2007.
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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for ensuring the safety and airworthiness of aircraft in Australia. This Act was enacted to address the need for comprehensive regulation of civil aviation, ensuring the safety of air navigation and the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations in the interests of aviation safety, and under these regulations, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for types of aircraft or aeronautical products. The objective of these regulations is to align Australia's aviation safety standards with international obligations, particularly under Annex 8 of the Convention on International Civil Aviation. CASA, acting as the national airworthiness authority, is responsible for issuing ADs that mandate safety requirements, ensuring that Australian aircraft meet international safety standards. The issuing of ADs is a critical function in maintaining the safety of civil aviation, and this legislative framework allows for effective coordination with international authorities, such as the European Aviation Safety Authority (EASA).
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. This authority is exercised to ensure the safety of air navigation, in line with the overarching objectives of the Civil Aviation Act 1988. An AD is a legislative instrument as defined under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives serve as the primary means for states to communicate ongoing airworthiness requirements, particularly when mandated by the State of Design under Annex 8 to the Convention on International Civil Aviation. The State of Registry, such as Australia, is responsible for ensuring the continuing airworthiness of aircraft registered within its jurisdiction, necessitating the adoption of ADs issued by the State of Design. In the case of European Aviation Safety Authority (EASA) AD 2007-0295-E for Agusta A109 helicopters, CASA has issued Australian AD/A109/60 following an assessment, reflecting Australia's international obligations and domestic safety protocols. Given the international nature and specific technical requirements of such directives, no public consultation is mandated, and a Regulatory Impact Statement is deemed unnecessary by the Office of Best Practice Regulation.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establish the framework within which airworthiness directives (ADs) are issued and enforced. Under section 98 of the Act, the Governor-General is empowered to make regulations for the purposes of the Act, ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular kinds of aircraft or aeronautical products. This regulation is further clarified by subregulation 39.001(5), which designates ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments in their own right.
The obligations and requirements imposed by these provisions are multi-faceted. Firstly, the State of Design, which is the country responsible for the original design of an aircraft type, has the primary responsibility for ensuring the continuing airworthiness of that type. This includes providing necessary information to appropriate States of Registry. Secondly, the State of Registry, which is the country where an aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction. CASA, as Australia’s national airworthiness authority, plays a critical role in this by assessing information from States of Design and issuing Australian ADs when necessary to enforce the requirements. The issuance of ADs is grounded in international obligations under Annex 8 to the Convention on International Civil Aviation, and these ADs are intended to maintain and enhance safety standards.
The consequences for non-compliance with these provisions are significant. Failure to adhere to an AD can lead to serious safety risks, and CASA has the authority to take enforcement actions against operators who do not comply. The Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties for non-compliance with ADs, but non-compliance can result in severe consequences, including the grounding of aircraft, legal action, and in extreme cases, the suspension or revocation of an operator’s licence. The regulatory framework is designed to ensure that all stakeholders, including aircraft manufacturers, operators, and regulatory authorities, understand their responsibilities and the importance of adhering to ADs to maintain the highest safety standards in aviation.
