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 206/78 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 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 was enacted to establish a comprehensive framework for the regulation of civil aviation in Australia, addressing the need for safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, delegating specific functions to the Civil Aviation Safety Authority (CASA). One such regulation, the Civil Aviation Safety Regulations 1998, allows CASA to issue airworthiness directives (ADs) for types of aircraft or aeronautical products to ensure continuing airworthiness in line with international standards. The ADs are integral to maintaining safety and compliance with international obligations under the Convention on International Civil Aviation. The legislative process for ADs involves CASA assessing and potentially issuing Australian ADs in response to directives from the State of Design, while also ensuring alignment with international practices.
The legislative instrument F2008L03674, issued under the Civil Aviation Act 1988, pertains to the cancellation of an existing AD affecting Bell 206 model aircraft, AD/BELL 206/78. This cancellation is due to the resolution of the unsafe condition that originally prompted the AD, and it reflects Australia’s commitment to international standards and obligations under the Convention on International Civil Aviation. No public consultation was required for this cancellation, as determined by the Office of Best Practice Regulation, which found that ADs do not necessitate a Regulatory Impact Statement. The AD was cancelled by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, as amended, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue ADs for types of aircraft or aeronautical products, with such directives being legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These ADs are integral to maintaining the continuing airworthiness of aircraft, with the State of Design having the primary responsibility for providing necessary information to the State of Registry. In Australia, CASA, as the national airworthiness authority, must issue Australian ADs when required by the State of Design, ensuring compliance with international standards set out in Annex 8 to the Convention on International Civil Aviation. The AD/BELL 206/78 concerning Bell 206 model aircraft has been assessed and subsequently cancelled by CASA due to the resolution of the unsafe condition, effective from 23 October 2008, without the need for a replacement AD. The cancellation process did not involve public consultation or require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. This includes the issuance of airworthiness directives (ADs) as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003 and are used to maintain the continuing airworthiness of aircraft types, as mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design, responsible for the aircraft type, provides necessary information, while the State of Registry, which in Australia is CASA, ensures that individual aircraft meet airworthiness standards.
In practical terms, when an AD is issued by a State of Design, CASA, as Australia's national airworthiness authority, is required to assess the information and, if deemed necessary, issue an Australian AD. This ensures that the requirements of the State of Design are enforced within Australia. For example, CASA issued AD/BELL 206/78 for Bell 206 model aircraft but later cancelled it after determining that the unsafe condition no longer existed. This cancellation took effect on 23 October 2008, and no replacement AD was necessary. This process adheres to Australia's obligations under the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties include ensuring that the State of Design provides sufficient information to maintain airworthiness. For the State of Registry, the obligation is to implement or adopt requirements that maintain the continuing airworthiness of aircraft registered within its jurisdiction. CASA, as the State of Registry, must assess foreign ADs and issue Australian ADs as necessary. This ensures that all aircraft within Australia meet the required safety standards. CASA is also responsible for communicating these directives to relevant stakeholders and enforcing compliance.
There are civil and criminal consequences for non-compliance with airworthiness directives. Under section 45A of the Civil Aviation Act 1988, operators of aircraft must comply with ADs. Failure to do so can result in significant penalties. For example, section 176 of the Act stipulates that an aircraft cannot be used in commercial air transport if it does not comply with an AD, and the operator can face fines of up to $150,000 for individuals and $750,000 for corporations. Additionally, CASA can issue a Notice of Proposed Penalty, leading to potential court proceedings and further penalties. These stringent measures are in place to ensure the highest standards of aviation safety are maintained.
