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.
CASA issued AD/BEECH 55/30 Amendment 1, affecting Beech 55 model aircraft in 1973. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, aims to ensure the safety and efficiency of civil aviation in Australia. This legislation provides the legal framework for regulating the aviation industry, including the establishment of the Civil Aviation Safety Authority (CASA) and the issuance of airworthiness directives (ADs) to ensure the ongoing airworthiness of aircraft. One of the key mechanisms under this Act is the ability of CASA to issue ADs, as outlined in the Civil Aviation Safety Regulations 1998, to mandate safety requirements for specific aircraft types or aeronautical products. The Civil Aviation Act 1988 facilitates the alignment of Australian aviation regulations with international standards set by the International Civil Aviation Organization (ICAO). This ensures that Australian aviation safety measures are consistent with global best practices. By enabling CASA to issue and manage ADs, the Act addresses the need for continuous oversight and enforcement of airworthiness standards to protect public safety in the aviation sector.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, with these directives being legislative instruments under the Legislative Instruments Act 2003. These directives are crucial for maintaining the continuing airworthiness of aircraft, in line with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of a particular aircraft type, and corresponding ADs are typically issued by the majority of ICAO Contracting States, including Australia. CASA, as Australia’s national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs based on information from the State of Design. This process ensures that the safety and regulatory requirements are consistently applied across the Australian Register. The AD/BEECH 55/30 Amendment 1, issued by CASA and affecting Beech 55 model aircraft from 1973, has been reviewed and cancelled, effective from 5 June 2008, as no replacement AD is required due to the age and historical modifications of the affected aircraft. This decision was made without public consultation as it reduces regulatory burden, and the Office of Best Practice Regulation has confirmed that ADs do not necessitate a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide a framework for the issuance and management of airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to create regulations for air navigation safety, and regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft or aeronautical products. An AD is a legislative instrument, as stipulated in subregulation 39.001(5) and the Acts Interpretation Act 1901. This legislative instrument is critical for maintaining the continuing airworthiness of aircraft types and individual aircraft.
The obligations imposed by these provisions on CASA and other parties are significant. CASA, as Australia’s national airworthiness authority, is mandated to assess ADs issued by the State of Design and to issue corresponding Australian ADs when necessary. The State of Registry, which in Australia is CASA, must ensure the continuing airworthiness of aircraft on the Australian Register. This involves developing or adopting appropriate requirements to maintain safety standards. Additionally, under Annex 8 to the Convention on International Civil Aviation, the State of Design has the responsibility to provide necessary information to ensure the continuing airworthiness of an aircraft type, and the State of Registry must use this information to maintain safety standards.
Failure to comply with the requirements of ADs or the regulations governing them can result in severe consequences. Although the specific penalties for breaching ADs are not detailed in the provided text, it is reasonable to infer that non-compliance could lead to civil or criminal penalties, given the critical nature of airworthiness directives in ensuring aviation safety. The absence of public consultation on the cancellation of AD/BEECH 55/30 Amendment 1, due to the reduction of regulatory burden, does not diminish the importance of adhering to these directives. Instead, it highlights the importance of regulatory efficiency while maintaining stringent safety standards. The AD cancellation, as mentioned, was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the legislative framework provided by the Act.
