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.
The Civil Aviation Safety Authority or its predecessors issued AD/AC-CLA/5 affecting Aircraft Parts and Development A-9 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AC-CLA/5. 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, Airframe and Structures, 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 comprehensive framework for the regulation of civil aviation in Australia, addressing the need for a cohesive and robust legal structure to ensure the safety and efficiency of air navigation. One of the key mechanisms through which this Act achieves its objective is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. This legislative framework ensures that the continuing airworthiness of aircraft is maintained in accordance with international standards, particularly those set by the International Civil Aviation Organization (ICAO). The cancellation of Australian AD/AC-CLA/5, affecting Aircraft Parts and Development A-9 series aeroplanes, is a direct response to Australia's obligations under the Convention on International Civil Aviation, demonstrating the commitment to international safety standards and the dynamic nature of regulatory requirements in the aviation sector.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Pursuant to section 98 of the Act, the Governor-General can make regulations, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue ADs for types of aircraft or aeronautical products. These ADs, as legislative instruments, are issued under Australia’s obligations to the Convention on International Civil Aviation, specifically Annex 8, which outlines the responsibility of the State of Design and the State of Registry in ensuring an aircraft’s continuing airworthiness. In this instance, CASA has cancelled an existing Australian AD/AC-CLA/5 pertaining to certain aircraft parts and aeroplanes, effective from 23 October 2008, due to the resolution of the unsafe condition previously identified. Given the nature of ADs and their alignment with international standards, no public consultation or Regulatory Impact Statement was required for this cancellation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are the primary legislative instruments that govern the issuance and management of airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are critical for maintaining the continuing airworthiness of aircraft, ensuring they meet safety standards set by the State of Design and the State of Registry, in line with Annex 8 to the Convention on International Civil Aviation.
The obligations placed on parties by this legislation include a duty for the State of Design to provide necessary information to ensure the continuing airworthiness of an aircraft type to the State of Registry, who is then responsible for the ongoing maintenance of airworthiness for individual aircraft. CASA, as the regulatory authority, is tasked with assessing, issuing, and cancelling ADs, as well as ensuring that these directives align with international standards. This includes the responsibility of cancelling an AD, as evidenced by the cancellation of Australian AD/AC-CLA/5, which was issued to address an unsafe condition in A-9 series aeroplanes. Given the cancellation due to Australia’s obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required.
Under this legislation, there are specific consequences for non-compliance with ADs. Although the exact civil and criminal penalties are not detailed in the text, the issuance and enforcement of ADs are integral to maintaining the safety and airworthiness of aircraft. Non-compliance with an AD could potentially result in enforcement actions by CASA, which might include fines, penalties, or even grounding of non-compliant aircraft. The maximum penalties for such offences are not explicitly stated in the text but would be aligned with the broader regulatory framework governing aviation safety in Australia.
