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/CESSNA 210/31 affecting Cessna 210 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 210/31. 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 establish a regulatory framework for civil aviation in Australia, ensuring safety and efficiency in the industry. Under this Act, the Civil Aviation Safety Regulations 1998 were formulated, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft and aeronautical products. The ADs are a legislative instrument made under the authority granted by section 98 of the Civil Aviation Act 1988, and they serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft, in line with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is responsible for assessing and, where necessary, issuing Australian ADs to address safety issues identified by the State of Design or other contracting states. The issuing and cancellation of such directives are critical to ensuring the safety of Australian airspace and compliance with international obligations.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The Act applies to all aircraft and aeronautical products within Australia, as well as to entities and individuals involved in the operation, maintenance, and registration of such aircraft. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products to ensure the continuing airworthiness of these items, making them a legislative instrument under the Legislative Instruments Act 2003. This regulatory approach is in line with Australia's obligations under Annex 8 of the Convention on International Civil Aviation, where the State of Design holds the primary responsibility for the continuing airworthiness of aircraft types, while the State of Registry ensures the ongoing airworthiness of individual aircraft. The geographic reach of this legislation is national, with CASA acting as Australia's national airworthiness authority. The Act does not specify exclusions or exemptions but operates under the broader international and domestic aviation safety frameworks.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance and management of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. This regulatory power is exercised under the overarching responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. In the context of Australia, CASA must assess any international ADs and, if deemed necessary, issue corresponding Australian ADs to maintain safety standards.
The obligations and requirements imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 mandate that CASA, as Australia’s national airworthiness authority, carefully evaluates ADs issued by the State of Design. CASA’s role includes assessing the information provided in international ADs to determine if an Australian AD is necessary. In the case of AD/CESSNA 210/31 affecting Cessna 210 aircraft, CASA has determined that the unsafe condition addressed by the AD no longer exists and has consequently cancelled the AD. This process ensures that Australian aircraft remain compliant with international safety standards while also reflecting current conditions and technological advancements.
The Civil Aviation Safety Regulations 1998 also specify that ADs are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, reflecting their technical and safety-focused nature. The AD/CESSNA 210/31 was cancelled in accordance with subsection 84A(2) of the Act by the Acting Manager, Systems and New Technologies, in the Airworthiness Engineering Branch on behalf of CASA. This action was taken to align with Australia’s obligations under the Convention on International Civil Aviation, and no consultation with the public was deemed necessary.
In terms of consequences for non-compliance, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict requirements for maintaining the airworthiness of aircraft. Failure to adhere to ADs, including the now-cancelled AD/CESSNA 210/31, could result in severe civil or criminal penalties. The specific penalties are not detailed in the provided text, but generally, violations of these regulations can lead to fines, imprisonment, or both, depending on the severity of the breach and the impact on aviation safety. The exact penalties would be determined based on the nature and extent of the non-compliance and the regulatory framework governing civil aviation safety in Australia.
