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/RES/24 affecting Aeronautic Equipment seat belts and harnesses. CASA has assessed this AD and as a result has cancelled Australian AD/RES/24. The cancellation will become effective on 9 April 2009. 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, Airframe and 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, enacted by the Parliament of Australia, was introduced to address the need for a comprehensive legislative framework to ensure the safety and efficiency of civil aviation within Australia. This Act provides the legal basis for the regulation of civil aviation, with a particular focus on air navigation safety and airworthiness of aircraft. The Civil Aviation Safety Regulations 1998, which were also enacted by the Parliament, further operationalise the provisions of the Civil Aviation Act 1988 by detailing the specific requirements for maintaining aircraft airworthiness, including the issuance of airworthiness directives (ADs). These ADs are legislative instruments made in accordance with section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998, with the overarching objective of ensuring the continuing airworthiness of aircraft in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation. In line with these international obligations, the Civil Aviation Safety Authority (CASA) issues ADs to address identified safety issues, and in this instance, Australian AD/RES/24 concerning Aeronautic Equipment seat belts and harnesses has been cancelled as the unsafe condition no longer exists.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This legislation applies to any individual or entity involved in the operation, maintenance, or manufacture of aircraft and aeronautical products within Australia. The geographic reach of this Act is national, as CASA is the central authority responsible for ensuring compliance with airworthiness standards across the Commonwealth. ADs, as legislative instruments, are designed to maintain the safety of air navigation by mandating specific requirements for aircraft and aeronautical products. These directives are issued under regulation 39.001 of the Civil Aviation Safety Regulations 1998 and are informed by international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, must ensure these standards are met and, where necessary, issue Australian ADs to enforce compliance. The scope of this legislation extends to all aircraft registered in Australia, ensuring that both domestic and international safety standards are adhered to, while the specific exclusions and exemptions are determined through subordinate instruments as needed.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations in the interests of air navigation safety. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations include ensuring the continuing airworthiness of aircraft and aeronautical products. The State of Design, which is responsible for the aircraft type, must provide necessary information to maintain airworthiness. CASA, as Australia's national airworthiness authority, must assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. Additionally, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft.
In the case of AD/RES/24, which affected Aeronautic Equipment seat belts and harnesses, CASA assessed the AD and subsequently cancelled it. The cancellation was made effective on 9 April 2009, and no replacement AD was required as the unsafe condition no longer existed. The cancellation was conducted in accordance with Australia's obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was deemed necessary.
The potential consequences for breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can be severe. Failure to comply with ADs can lead to significant penalties. Under section 328 of the Act, individuals can be fined up to 200 penalty units ($42,500 as of 2023) or, in the case of a body corporate, up to 1,000 penalty units ($212,500 as of 2023). Furthermore, under section 334, CASA can impose administrative penalties, including fines, for non-compliance with regulations. These penalties underscore the importance of adhering to airworthiness directives to maintain safety standards in aviation.
