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.
Transport Canada has issued AD CF-2009-11 affecting Bombardier DHC-8 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/146, which will become effective on 17 March 2009.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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& Structures 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 regulate civil aviation in Australia and ensure safety standards are met. One of the critical mechanisms introduced under this Act is the issuance of airworthiness directives (ADs), which are regulations designed to address specific safety concerns regarding aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998, made under section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. The objective of these ADs is to ensure the continuing airworthiness of aircraft in accordance with international standards, particularly those set by the International Civil Aviation Organization (ICAO). As Australia is a signatory to the Convention on International Civil Aviation, it is obligated to align its regulatory practices with ICAO standards, which necessitates the issuance of ADs when safety concerns are identified by the State of Design or other contracting states. These ADs are legislative instruments, subject to disallowance by Parliament, and are issued under the authority of CASA without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, applies to entities involved in the aviation industry, specifically focusing on the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments, as outlined in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are issued in response to Australia's obligations under the Convention on International Civil Aviation, with the State of Registry responsible for the continuing airworthiness of aircraft registered within Australia. CASA, as the national airworthiness authority, assesses and issues Australian ADs based on information from the State of Design, such as the recent AD/DHC-8/146 issued in response to Transport Canada's AD CF-2009-11 for Bombardier DHC-8 model aircraft. Given the international obligations and the technical nature of the ADs, there is no requirement for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations necessary for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products to ensure they meet continuing airworthiness standards. An AD is a legislative instrument that can be disallowed under section 46A of the Acts Interpretation Act 1901, and it is subject to the requirements of the Legislative Instruments Act 2003.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include ensuring the continuing airworthiness of aircraft registered in Australia. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure continuing airworthiness, as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is required to assess information from the State of Design and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This process ensures that Australian aircraft meet international safety standards and facilitates compliance with international obligations.
Breaching the requirements of an AD can lead to serious consequences, both civil and criminal. Under the Civil Aviation Act 1988, non-compliance with ADs can result in significant penalties. For corporations, the maximum penalty can include substantial fines, up to the greater of $1.65 million or three times the benefit obtained through the breach. For individuals, the maximum penalty can include imprisonment for up to five years or substantial fines. Furthermore, CASA has the authority to take enforcement actions, including grounding aircraft that do not comply with ADs, which can severely impact the operations of airlines and other aviation entities. These stringent measures underscore the importance of adhering to airworthiness directives to maintain the safety and integrity of the aviation industry.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for the issuance and enforcement of airworthiness directives. CASA is tasked with ensuring that Australian aircraft meet international safety standards, and failure to comply with these directives can result in severe penalties, reinforcing the critical role of ADs in maintaining aviation safety.
