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 206/15 affecting Bell 206A 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 Technologies 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 legislative framework for ensuring the safety of air navigation in Australia, with the Civil Aviation Safety Regulations 1998 detailing the requirements for aircraft airworthiness. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments designed to maintain the continuing airworthiness of aircraft. These directives are issued in accordance with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation. The Act facilitates CASA's role in assessing and implementing ADs issued by the aircraft's State of Design, ensuring that Australian aircraft meet international safety standards. The AD/BELL 206/15, which affected Bell 206A model aircraft, has been cancelled by CASA due to the resolution of the unsafe condition it addressed, thus fulfilling Australia's obligations under the Convention. This action was taken without public consultation, as determined by the Office of Best Practice Regulation, which found that such ADs do not require a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide for the issuance of airworthiness directives (ADs) that apply to specific types of aircraft and aeronautical products, aiming to maintain safety standards in air navigation. These directives are legislative instruments and are essential for ensuring the continuing airworthiness of aircraft as mandated by the State of Registry and Design under international aviation conventions. The Civil Aviation Safety Authority (CASA), acting on behalf of Australia, issues these directives to address safety concerns or rectify deficiencies identified in aircraft or aeronautical products. The process involves CASA assessing directives issued by the State of Design and, if necessary, issuing corresponding Australian ADs. For instance, CASA issued and subsequently cancelled AD/BELL 206/15 for Bell 206A model aircraft, reflecting Australia’s compliance with international obligations under the Convention on International Civil Aviation. This regulatory action was carried out without public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The cancellation of this AD, effective from 23 October 2008, signifies that no further action is required as the identified unsafe condition no longer exists.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish a framework for issuing airworthiness directives (ADs) aimed at ensuring the safety of air navigation. According to section 98 of the Act, the Governor-General is empowered to make regulations for the purposes of the Act, which includes ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for particular types of aircraft or aeronautical products. It is important to note that these ADs are legislative instruments, as per section 46A of the Acts Interpretation Act 1901, and are subject to disallowance.
Under the obligations imposed by these provisions, the State of Design of an aircraft type has the primary responsibility for ensuring the continuing airworthiness of that type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to ensure the continuing airworthiness of the aircraft type to the appropriate States of Registry. The State of Registry, which is responsible for the individual aircraft’s continuing airworthiness, must then develop or adopt requirements to maintain the airworthiness of the aircraft. When an AD is issued by the State of Design against a type of aircraft registered in Australia, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design.
Failing to comply with the provisions of an AD can result in significant consequences. While the specific offences, penalties, or civil and criminal consequences for breach of an AD are not detailed in the provided text, the general principle is that non-compliance with ADs can lead to serious safety issues and potential legal repercussions. Given that ADs are legislative instruments, any breach could potentially be subject to the penalties outlined in the relevant legislation, which may include fines, imprisonment, or other regulatory actions. Therefore, it is crucial for all parties governed by these regulations to adhere strictly to the mandates issued in ADs to ensure the safety and compliance of aircraft operations within Australia.
