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/BELL 206/45 affecting Bell 206B model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 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 Manager, Systems and New Technology in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, with a strong focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of safety within the realm of civil aviation. One such regulation, under section 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives, which are legislative instruments under the Legislative Instruments Act 2003, serve to maintain the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation. This legislative framework ensures that CASA, as Australia's national airworthiness authority, can appropriately respond to safety directives issued by the State of Design and take necessary actions to protect the public.
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 specific types of aircraft or aeronautical products, in line with the Civil Aviation Act 1988. These ADs are essential for ensuring the continuing airworthiness of aircraft and are a common form of information dissemination under Annex 8 to the Convention on International Civil Aviation. The ADs are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. CASA, as Australia's national airworthiness authority, is responsible for assessing ADs issued by the State of Design and, if appropriate, issuing Australian ADs to enforce the requirements. In the specific case of AD/BELL 206/45 affecting Bell 206B model aircraft, CASA assessed the directive and subsequently cancelled it, effective from 23 October 2008, due to the unsafe condition no longer existing, thus eliminating the need for a replacement AD. Given the cancellation is a result of Australia's obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, as relevant to the issuance of airworthiness directives, include section 98, which empowers the Governor-General to make regulations in the interests of the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that an AD is a disallowable instrument, meaning it is subject to parliamentary disallowance, and a legislative instrument under the Legislative Instruments Act 2003. Annex 8 to the Convention on International Civil Aviation outlines the responsibilities of the State of Design in ensuring the continuing airworthiness of an aircraft type and mandates the provision of necessary information to States of Registry. The State of Registry, such as CASA in Australia, is responsible for the continuing airworthiness of individual aircraft and must develop or adopt requirements to ensure this.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and the State of Registry include the assessment and implementation of airworthiness directives issued by the State of Design. When a State of Design issues an AD, CASA must review the information and, if appropriate, issue an Australian AD to enforce the requirements. This ensures that the safety standards set by the State of Design are met within the Australian context. Furthermore, the State of Registry must ensure that all aircraft under its purview meet the continuing airworthiness standards and that any ADs issued are effectively communicated and enforced within the country.
The consequences of non-compliance with the airworthiness directives issued under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can be significant. While the specific penalties for breach are not detailed in the provided text, non-compliance with airworthiness directives can generally result in severe civil and criminal penalties. These may include fines, imprisonment, and the potential grounding of non-compliant aircraft. Such measures are in place to enforce the high safety standards required in aviation, ensuring that all aircraft operate within safe parameters. The authority to issue and enforce ADs is a critical tool in maintaining the safety and integrity of the aviation industry.
