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/EMB-110/14 affecting Embraer EMB-110 (Bandeirante) series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/EMB-110/14. The cancellation will become effective on 18 December 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, with a strong emphasis on safety. It empowers the Governor-General to make regulations to ensure the safety of air navigation, including the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998 further detail the responsibilities and processes for issuing these directives, which are legislative instruments under the Legislative Instruments Act 2003. The Civil Aviation Safety Authority (CASA), acting as Australia’s national airworthiness authority, is tasked with ensuring the continuing airworthiness of aircraft by assessing and implementing directives issued by States of Design and Registry in accordance with international standards set by the Convention on International Civil Aviation. The Act and its regulations collectively aim to maintain the highest safety standards in Australian civil aviation, reflecting the nation's commitment to international aviation safety protocols.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the framework for issuing airworthiness directives (ADs) in Australia to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments, are essential for maintaining the continuing airworthiness of aircraft and are aligned with the responsibilities of the State of Design and State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, assesses ADs issued by the State of Design and may issue corresponding Australian ADs if necessary. The scope of these regulations applies to all aircraft registered in Australia, ensuring that safety standards are consistently met across the national fleet. The Act and associated regulations have a national reach and are designed to protect public safety within Australian airspace. There are no stated exclusions or exemptions in the issuance of ADs, although their application is contingent on CASA’s assessment of the specific safety concerns.
Key Provisions
The Civil Aviation Safety Regulations 1998 (section 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003, and they are integral to maintaining the safety and airworthiness of aircraft types registered in Australia. The State of Design, which is responsible for the design of an aircraft, must provide necessary information to ensure the aircraft’s continuing airworthiness, and this is typically communicated through ADs. In the case of aircraft registered in Australia, CASA must assess the ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required safety measures.
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA is tasked with ensuring the safety of air navigation and the continuing airworthiness of aircraft registered in Australia. This includes the responsibility to monitor and respond to ADs issued by States of Design, assessing whether these directives necessitate the issuance of corresponding Australian ADs. CASA's role is critical in maintaining the safety standards of aircraft, particularly those that present potential safety concerns. When an AD is issued by a State of Design, CASA must review the directive, verify its necessity, and if appropriate, issue a corresponding AD to mandate the required safety measures on aircraft registered in Australia.
The obligations imposed on CASA include the assessment of foreign ADs and the issuance of Australian ADs where necessary, as mandated by the Civil Aviation Safety Regulations 1998 (section 39.001). CASA must ensure that all aircraft registered in Australia meet the required safety standards by implementing the necessary measures as outlined in relevant ADs. The authority to issue ADs is derived from section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations for the safety of air navigation. This regulatory framework ensures that CASA can respond promptly to safety issues identified by States of Design, thereby maintaining the high safety standards of Australian civil aviation.
Failure to comply with ADs can result in serious safety risks and legal consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to civil penalties, including fines. The maximum penalty for contravening an AD can be substantial, reflecting the importance of adhering to these safety directives. Additionally, CASA has the authority to take enforcement actions against entities or individuals who fail to comply with ADs, which can include grounding of aircraft or other regulatory measures. The seriousness of these consequences underscores the critical nature of ADs in maintaining the safety and airworthiness of aircraft in Australia.
