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 412/10 affecting Bell 412 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 18 December 2008. 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, 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, enacted to govern civil aviation in Australia, was introduced to ensure the safety of air navigation and to address various regulatory gaps in the sector. Section 98 of the Act empowers the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are legislative instruments and are essential for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The cancellation of an existing AD for Bell 412 aircraft, effective from 18 December 2008, was undertaken in compliance with Australia’s obligations under this international convention, and did not require public consultation or a Regulatory Impact Statement. The AD cancellation was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA.
Scope and Application
The Civil Aviation Act 1988 and its accompanying regulations, including the Civil Aviation Safety Regulations 1998, govern the issuance of airworthiness directives (ADs) for aircraft and aeronautical products in Australia, with the primary objective of ensuring the safety of air navigation. According to regulation 39.001 of the Civil Aviation Safety Regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and thus subject to scrutiny under the Legislative Instruments Act 2003. These ADs play a crucial role in maintaining the continuing airworthiness of aircraft types, as per Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as responsible for the airworthiness of an aircraft type, and the State of Registry as responsible for the airworthiness of individual aircraft. This legislation applies to aircraft manufacturers, operators, and regulatory authorities within Australia, ensuring compliance with international safety standards and obligations under the Convention on International Civil Aviation. Although no public consultation has been conducted for the cancellation of specific ADs due to Australia's international obligations, the ADs remain a fundamental tool in the maintenance of air safety within the nation.
Key Provisions
The Civil Aviation Safety Regulations 1998 (Regulation 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are formal legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. An example of such an AD, AD/BELL 412/10, which concerned Bell 412 aircraft, was issued by CASA or its predecessors and has since been cancelled. The cancellation, effective as of 18 December 2008, was due to Australia's commitments under the Convention on International Civil Aviation, specifically Annex 8, which places the responsibility for continuing airworthiness of an aircraft type on the State of Design and the State of Registry. Since this cancellation aligns with international obligations, it did not require public consultation or a Regulatory Impact Statement.
Under the Civil Aviation Safety Regulations 1998, the obligations imposed by these airworthiness directives primarily fall on CASA and the State of Registry of individual aircraft. CASA is tasked with issuing ADs to ensure the safety of air navigation, in line with international standards set by the International Civil Aviation Organization (ICAO). The State of Registry, meanwhile, must implement and enforce the requirements outlined in these directives to maintain the continuing airworthiness of the aircraft within its jurisdiction. This includes ensuring that all necessary modifications and inspections are carried out in accordance with the ADs.
Breach of the obligations stipulated in airworthiness directives can lead to significant consequences. While the Civil Aviation Safety Regulations 1998 do not specify particular offences or penalties for non-compliance with ADs, failure to adhere to these directives can result in severe civil and criminal liabilities under other sections of the Civil Aviation Act 1988. Non-compliance may lead to enforcement actions by CASA, including fines, suspension, or revocation of aircraft certificates of airworthiness. In extreme cases, there could be criminal charges resulting in substantial penalties, both financial and custodial, for individuals or entities found guilty of failing to comply with ADs.
Given the critical nature of airworthiness directives, it is imperative that all relevant parties, including aircraft owners, operators, and maintenance personnel, are fully aware of and comply with the directives issued by CASA. Failure to do so not only risks the safety of passengers and crew but also subjects the violators to potential legal and financial repercussions. Therefore, adherence to these directives is not only a regulatory requirement but a fundamental obligation to ensure the safety and integrity of Australia's aviation industry.
