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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/BELL 412/25 affecting Bell 412 helicopters in 1989. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 19 November 2009. No replacement AD is required.
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, New Technology and Regulatory Trends, in the Standards Development and Future Technology Division, 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, ensuring the safety and efficiency of the aviation industry. One of the key provisions of this Act is the authority it grants the Governor-General to make regulations that support the Act’s objectives, particularly in relation to the safety of air navigation. This legislative power is exercised through the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are legislative instruments that serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under international conventions such as Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act 1988 thus addresses the need for a robust regulatory framework to manage aviation safety standards effectively, reflecting Australia's commitment to global aviation safety protocols.
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) concerning specific types of aircraft or aeronautical products, with the overarching goal of ensuring the safety of air navigation as mandated by section 98 of the Civil Aviation Act 1988. These ADs, which are legislative instruments as per the Legislative Instruments Act 2003, are integral to maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in this context refers to Australia for registered aircraft, is tasked with ensuring the ongoing airworthiness of each aircraft. In accordance with these regulations, CASA has issued, reviewed, and subsequently cancelled AD/BELL 412/25, which pertained to Bell 412 helicopters, effective from 19 November 2009. This cancellation was made in line with Australia's commitments under the Convention on International Civil Aviation, and thus no public consultation or Regulatory Impact Statement was required. The decision to cancel the directive was executed by the Manager, New Technology and Regulatory Trends, in the Standards Development and Future Technology Division of CASA, in accordance with subsection 84A(2) of the Act.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, as amended, pertain to the issuance of airworthiness directives (ADs) as outlined in regulation 39.001 (5). These directives are legislative instruments under the Acts Interpretation Act 1901 and are essential for ensuring the continuing airworthiness of aircraft types. Regulation 39.001 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs, which are critical for maintaining safety standards in air navigation. The cancellation of a specific AD, such as AD/BELL 412/25 affecting Bell 412 helicopters, is documented and takes effect on a specified date, as in this case, 19 November 2009. The cancellation does not necessitate a replacement AD, as it aligns with Australia's obligations under the Convention on International Civil Aviation.
The obligations imposed by these regulations primarily rest on CASA, which is tasked with ensuring the ongoing airworthiness of aircraft through the issuance and management of ADs. CASA must adhere to international standards and practices as stipulated by Annex 8 of the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and the State of Registry. Specifically, CASA must provide necessary information to ensure the continuing airworthiness of aircraft types and must review and, if necessary, cancel existing ADs in accordance with international obligations. The State of Registry, on the other hand, must implement and enforce the ADs to maintain the airworthiness of individual aircraft registered within its jurisdiction.
Failure to comply with the provisions of the Civil Aviation Safety Regulations 1998, including the proper issuance, enforcement, and cancellation of ADs, can lead to significant consequences. While the specific offences and penalties are not detailed in the provided text, it is evident that non-compliance with ADs can compromise the safety of air navigation. Such breaches could potentially result in civil or criminal penalties, although the exact nature and severity of these penalties would depend on the specific regulatory context and any additional relevant legislation. The overarching objective of these regulations is to ensure that all parties involved—CASA, the State of Design, and the State of Registry—uphold the highest safety standards in civil aviation.
