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/RES/25, affecting unapproved seat mounted cargo restraints in 1990. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 22 November 2007. No replacement AD is required, as the original unsafe condition is addressed by Civil Aviation Regulation (1988) 42U.
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 was enacted to provide a legislative framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft within Australia. The Civil Aviation Safety Regulations 1998 were subsequently introduced to provide further detail on the regulatory requirements under the Act. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that are necessary for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The objective of these regulations is to ensure that aircraft and aeronautical products meet the required safety standards and remain airworthy throughout their operational life. The issuance of ADs is a key mechanism by which CASA, as Australia's national airworthiness authority, mandates safety requirements and ensures compliance with international standards set out in Annex 8 to the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and their creation follows the guidelines set forth in the Legislative Instruments Act 2003. In accordance with international standards, the State of Design holds the primary responsibility for the continuing airworthiness of aircraft types and must furnish necessary information to the States of Registry, which are then tasked with ensuring the ongoing airworthiness of aircraft within their jurisdictions. CASA, acting as Australia's national airworthiness authority, is responsible for assessing this information and, if necessary, issuing corresponding Australian ADs to enforce the requirements set by the State of Design. The cancellation of AD/RES/25, which affected unapproved seat-mounted cargo restraints, exemplifies this process and was carried out to reduce regulatory burden, with no requirement for public consultation or a Regulatory Impact Statement. The AD cancellation is effective from 22 November 2007, and no replacement AD is needed as the original issue has been addressed by Civil Aviation Regulation 1988, 42U.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation, with specific provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Act empowers the Governor-General to make regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue ADs for certain types of aircraft or aeronautical products (section 39.001(5)). These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003, and they serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions are significant for both CASA and the States of Design and Registry. The State of Design has the primary responsibility for ensuring the continuing airworthiness of an aircraft type, including providing necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft within its jurisdiction. CASA, acting as Australia's national airworthiness authority, must assess information from the State of Design and, if necessary, issue Australian ADs to enforce the design state's requirements. This process ensures that any identified safety issues are addressed comprehensively and effectively.
Failure to comply with the ADs can lead to serious consequences, both civil and criminal. The Civil Aviation Act 1988 and associated regulations do not specify detailed penalties for non-compliance with ADs; however, general aviation offences under the Act can result in substantial fines and imprisonment. For instance, section 45 of the Act provides that a person who contravenes any regulation made under the Act is liable to a fine of up to $126,000 for an individual and up to $630,000 for a body corporate, along with potential imprisonment terms. These penalties underscore the importance of adhering to ADs to maintain the highest safety standards in air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for the issuance and enforcement of airworthiness directives, with clear responsibilities for the States of Design and Registry and significant consequences for non-compliance. The interaction between these provisions and international standards ensures that the safety of air navigation is prioritised and maintained through effective regulatory measures.
