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 206/43 affecting Bell 206 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 Technology 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 ensure the safety of air navigation, empowers the Governor-General to establish regulations that serve this purpose. This legislative framework is complemented by the Civil Aviation Safety Regulations 1998, which, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types and aeronautical products. These directives, as legislative instruments, are integral to maintaining the safety standards required by Annex 8 of the Convention on International Civil Aviation. The State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry ensures the airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, issues Australian ADs when necessary, reflecting its commitment to international safety standards.
The issuance and subsequent cancellation of AD/BELL 206/43 concerning Bell 206 model aircraft exemplifies the dynamic nature of airworthiness management. CASA assessed the directive and, finding the unsafe condition no longer present, cancelled it, effective from 23 October 2008. This action aligns with Australia's obligations under the Convention on International Civil Aviation, obviating the need for public consultation or a Regulatory Impact Statement. The cancellation was authorised by the Manager, Systems and New Technology in the Airworthiness Engineering Group at CASA, in accordance with the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Safety Regulations 1998, which are an instrument of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. This regulatory framework ensures that CASA can mandate requirements for the continuing airworthiness of aircraft registered in Australia, thereby fulfilling Australia's obligations under the Convention on International Civil Aviation. ADs are crucial as they provide essential information to maintain the safety standards of aircraft, and their issuance is in line with Annex 8 of the Convention, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type. The AD/BELL 206/43 concerning Bell 206 model aircraft, which has been cancelled by CASA, exemplifies this process. Given that the cancellation of this AD was due to the fulfilment of international obligations, no public consultation was deemed necessary, and it was determined that a Regulatory Impact Statement was not required. This legislative approach ensures that CASA, as Australia's national airworthiness authority, can effectively respond to safety concerns and align with international standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, section 98 of the Act authorises the Governor-General to make regulations for the purposes of the Act and in the interests of safety, and regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. Subregulation 39.001(5) specifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901 and therefore a legislative instrument according to the Legislative Instruments Act 2003.
The Act and Regulations impose obligations on CASA to assess and, if appropriate, issue ADs that align with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design of an aircraft type has the primary responsibility for ensuring the continuing airworthiness of the aircraft and must provide necessary information to the States of Registry, including Australia. CASA, as the national airworthiness authority, must evaluate this information and issue Australian ADs as necessary. This ensures that aircraft registered in Australia comply with safety standards.
Breach of the requirements set forth in ADs can have significant legal consequences. Failure to comply with an AD can result in the aircraft being considered unairworthy, leading to potential grounding of the aircraft. Civil penalties for non-compliance can include fines, and in more serious cases, criminal penalties may be imposed, depending on the severity of the breach and the impact on aviation safety. The specific penalties are not detailed in the given text but generally reflect the seriousness of non-compliance with safety regulations.
In this particular instance, the AD/BELL 206/43 for Bell 206 model aircraft has been cancelled by CASA, effective from 23 October 2008, due to the resolution of the unsafe condition. This cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was required. The AD was issued by the Manager, Systems and New Technology in the Airworthiness Engineering Group on behalf of CASA, in accordance with subsection 84A(2) of the Act.
