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 Civil Aviation Safety Authority or its predecessors issued AD/BEECH 23/37 affecting Beech B19 and C23 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 23/37. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety and efficiency of civil aviation within Australia, providing the legislative framework for the regulation of air navigation and the continuing airworthiness of aircraft. The Act was introduced to address the need for a robust regulatory environment to manage the complexities and risks associated with civil aviation. The Civil Aviation Safety Regulations 1998, made under section 98 of the Act, further detail the requirements for airworthiness and the issuance of airworthiness directives (ADs). These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). The Act reflects the policy objective of maintaining the highest safety standards in civil aviation, in line with Australia's obligations under international conventions, and mandates CASA to issue and manage ADs as necessary to uphold these standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the overarching authority 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 framework applies to aircraft registered within Australia and extends to the entities responsible for ensuring the ongoing airworthiness of these aircraft, including manufacturers, operators, and maintenance providers. The regulations are designed to align with international standards set by the Convention on International Civil Aviation, particularly under Annex 8, which places responsibility for the continuing airworthiness of aircraft types with the State of Design and mandates that States of Registry adopt or develop requirements to maintain airworthiness. The ADs issued by CASA are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and are regulated by the Legislative Instruments Act 2003. Notably, ADs do not require a Regulatory Impact Statement or public consultation, as determined by the Office of Best Practice Regulation. The authority to issue or cancel such directives is exercised by CASA, reflecting its role as Australia's national airworthiness authority.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Act empowers the Governor-General to create regulations for air navigation safety, while regulation 39.001 of the 1998 Regulations allows CASA to issue ADs for types of aircraft or aeronautical products. This regulatory mechanism is designed to ensure that aircraft maintain their airworthiness over time. Subregulation 39.001(5) designates ADs as disallowable instruments, meaning they are legislative instruments subject to specific parliamentary scrutiny procedures, as outlined in the Legislative Instruments Act 2003.
The obligations and requirements imposed by these provisions on CASA and other entities include assessing the continuing airworthiness of aircraft in accordance with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the manufacturer, has the primary responsibility for providing necessary information to ensure the continuing airworthiness of an aircraft type. The State of Registry, which is Australia in this context, must implement or adopt requirements that ensure the ongoing airworthiness of aircraft registered within its jurisdiction. CASA, as Australia's national airworthiness authority, must review and, if necessary, adopt or issue ADs based on information from the State of Design to meet these obligations. For instance, in the case of the Beech B19 and C23 model aircraft, CASA assessed and subsequently cancelled the Australian AD/BEECH 23/37 because the unsafe condition identified by the original directive no longer existed.
In terms of consequences for non-compliance, the Act and Regulations do not explicitly outline specific offences or penalties for failing to comply with ADs. However, failure to comply with ADs can lead to serious safety risks, which could result in enforcement actions by CASA, such as grounding of aircraft, fines, or other regulatory sanctions. The absence of a specific penalty in the text suggests that general aviation safety laws and regulations, which carry their own penalties, are likely to apply in cases of non-compliance. It is also worth noting that because ADs are legislative instruments, their issuance and enforcement are subject to rigorous procedural and parliamentary scrutiny to ensure they are justifiable and necessary.
