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/AC-CLA/3 affecting all Aircraft Parts and Development A-9 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AC-CLA/3. The cancellation will become effective on 28 August 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, Airframe and Structures, 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 ensure the safety and efficiency of civil aviation in Australia. The Act provides the legislative framework within which the Civil Aviation Safety Authority (CASA) can operate to manage and regulate the safety aspects of civil aviation. One of the mechanisms through which CASA exercises its regulatory functions is by issuing airworthiness directives (ADs). These ADs are designed to address safety issues by mandating specific actions to maintain the airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 further detail the process by which these ADs can be issued and managed, reflecting Australia's commitment to international standards as set out in the Convention on International Civil Aviation. The ADs are a crucial tool for CASA to ensure compliance with both national and international safety requirements, thereby safeguarding the interests of the public and the integrity of the aviation sector.
Scope and Application
The Civil Aviation Act 1988, coupled with the Civil Aviation Safety Regulations 1998, provides the legislative framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Under the Act, the Governor-General has the authority to make regulations that pertain to the safety of air navigation, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These ADs, as legislative instruments, are subject to disallowance and scrutiny under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are instrumental in maintaining the continuing airworthiness of aircraft, a responsibility primarily vested in the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is tasked with assessing the information provided by the State of Design and issuing corresponding Australian ADs when necessary. The AD/AC-CLA/3, which originally affected all Aircraft Parts and Development A-9 series aeroplanes, has been cancelled by CASA due to the non-existence of the unsafe condition it was intended to address, and this cancellation aligns with Australia’s international obligations.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 address the issuance of airworthiness directives (ADs) as per section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998. Section 39.001(5) specifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument as per section 6 of the Legislative Instruments Act 2003. This means that ADs are formal regulatory instruments that carry the force of law. Under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry. The State of Registry, in this case CASA, must then ensure the continuing airworthiness of the aircraft and may issue ADs to enforce this responsibility. The Civil Aviation Safety Authority has assessed and subsequently cancelled AD/AC-CLA/3, which affected all Aircraft Parts and Development A-9 series aeroplanes, due to the unsafe condition no longer existing. This cancellation aligns with Australia's obligations under the Convention on International Civil Aviation and takes effect on 28 August 2008.
The obligations imposed by these regulations require the State of Design to maintain and provide continuing airworthiness information, while the State of Registry must adopt and enforce corresponding requirements. CASA, as the national airworthiness authority, must assess the ADs issued by the State of Design and determine if an Australian AD is necessary to ensure compliance with safety standards. The Manager, Airframe and Structures, in the Airworthiness Engineering Branch, issues these ADs on behalf of CASA, in accordance with subsection 84A(2) of the Act. Given the international nature of aviation, these obligations extend beyond domestic considerations to encompass global safety standards and interoperability.
Failure to comply with ADs can result in serious consequences, including potential breaches of safety regulations. The Civil Aviation Act 1988 and associated regulations impose penalties for non-compliance, although specific penalties are not detailed in the text. Generally, breaches of these regulations can lead to fines, imprisonment, or both, depending on the severity of the breach and its impact on aviation safety. The Civil Aviation Safety Regulations 1998 provide a framework within which CASA can enforce compliance, ensuring that all parties involved in aviation operations adhere to the highest safety standards. The cancellation of AD/AC-CLA/3 reflects a commitment to maintaining these standards, and any failure to comply with the resultant regulations could lead to enforcement actions by CASA.
