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 206/58 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 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 by the Australian Parliament, governs the regulation of civil aviation to ensure the safety of air navigation. The Act empowers the Governor-General to issue regulations in the interest of aviation safety, with the Civil Aviation Safety Regulations 1998 outlining the procedures for issuing airworthiness directives (ADs) to maintain aircraft airworthiness. These ADs are legislative instruments subject to disallowance, reflecting the statutory framework's commitment to safety and compliance with international standards. The Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific aircraft types or aeronautical products, ensuring the continuing airworthiness of aircraft registered in Australia. The cancellation of AD/BELL 206/58 for Bell 206B model aircraft, effective from 23 October 2008, exemplifies CASA's role in monitoring and enforcing airworthiness standards based on international obligations and safety assessments.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Governor-General to issue regulations aimed at ensuring the safety of air navigation. Regulation 39.001 specifically authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These directives are legislative instruments and subject to disallowance under section 46A of the Acts Interpretation Act 1901 and regulation by the Legislative Instruments Act 2003. The ADs are primarily a mechanism for the State of Design to communicate necessary information to States of Registry, ensuring the continuing airworthiness of aircraft types, in line with Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is obligated to review and, if necessary, issue Australian ADs to enforce these requirements. In the case of AD/BELL 206/58, affecting Bell 206B model aircraft, CASA has assessed the AD and subsequently cancelled it, effective 23 October 2008, due to the resolution of the unsafe condition, thereby obviating the need for a replacement AD. The cancellation aligns with Australia's international obligations and does not necessitate public consultation or a Regulatory Impact Statement. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Group at CASA, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations in the interest of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as legislative instruments, as stipulated in the Legislative Instruments Act 2003, and they are critical for ensuring the continuing airworthiness of aircraft types, as per Annex 8 of the Convention on International Civil Aviation. The State of Design is primarily responsible for providing necessary information to maintain airworthiness, while the State of Registry, represented by CASA in Australia, is tasked with implementing these requirements domestically.
CASA's role is pivotal in ensuring that Australian aircraft meet international safety standards. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate the information provided and, if necessary, issue an Australian AD to enforce the requirements. This ensures that Australian aircraft remain compliant with international safety standards. In this context, AD/BELL 206/58, which affected Bell 206B model aircraft, was assessed by CASA and subsequently cancelled. The cancellation of this AD, effective from 23 October 2008, reflects Australia's adherence to international obligations under the Convention on International Civil Aviation, and it signifies that the unsafe condition previously identified no longer exists.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the State of Registry and CASA include the continuous assessment and enforcement of airworthiness directives. CASA's responsibility extends to ensuring that any AD issued by a State of Design is appropriately implemented in Australia, maintaining the safety and airworthiness of all aircraft registered in the country. This involves rigorous assessment and, where necessary, the issuance of corresponding Australian ADs. The process is designed to ensure that all regulatory measures align with international standards, thereby safeguarding the safety of air navigation.
Failure to comply with the airworthiness directives or any related regulations under the Civil Aviation Safety Regulations 1998 can lead to significant legal consequences. While the specific penalties are not detailed in the provided text, non-compliance with such directives can generally result in enforcement actions, including fines, penalties, or other regulatory sanctions. These measures are designed to ensure that all parties adhere to the stringent safety standards set forth by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, thereby maintaining the highest levels of air safety.
