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 Brazilian ANAC has issued AD 2006-03-01R1 affecting Embraer EMB-145 model aircraft. Brazil is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/EMB-145/8, which will become effective on 31 July 2008.
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, Systems and New Technologies 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 civil aviation in Australia, ensuring the safety, efficiency, and orderly development of civil aviation. The Act empowers the Governor-General to make regulations that are integral to the safety of air navigation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This legislative instrument addresses the need for standardised safety measures across the aviation industry, aligning with international standards and obligations under the Convention on International Civil Aviation. CASA, as the national airworthiness authority, is tasked with assessing and issuing ADs in response to directives from the aircraft's State of Design, ensuring that Australian-registered aircraft meet international safety standards. The policy objective is to maintain and enhance the safety of civil aviation by ensuring compliance with international agreements and domestic regulations.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) within Australia, ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products, which are considered legislative instruments under section 46A of the Acts Interpretation Act 1901. These ADs are instrumental in maintaining the continuing airworthiness of aircraft types and are mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case Brazil, has a responsibility to provide necessary information to maintain airworthiness, and CASA, as Australia’s national airworthiness authority, must assess and, if appropriate, issue corresponding Australian ADs to enforce the requirements of the State of Design. Exemptions and thresholds are not explicitly detailed in the text, but the issuance of ADs follows Australia's obligations under international conventions and is implemented without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs) in Australia, as per section 98 of the Act and regulation 39.001 of the Regulations (sections 98, 39.001). ADs are legislative instruments that serve to maintain the airworthiness of aircraft by mandating specific requirements or actions. The State of Design, such as Brazil for the Embraer EMB-145 model aircraft, is responsible for issuing ADs, and the State of Registry, such as Australia, must implement these directives (sections 39.001(5), Annex 8). CASA, as the national airworthiness authority, evaluates the foreign ADs and, if necessary, issues corresponding Australian ADs to ensure compliance and safety.
The obligations imposed by these provisions include the assessment and implementation of ADs issued by the State of Design. CASA is required to assess any foreign ADs relevant to aircraft on the Australian Register and, if appropriate, issue corresponding Australian ADs to ensure the continuing airworthiness of these aircraft (section 98). The State of Registry must also develop or adopt requirements to ensure the continuing airworthiness of aircraft in accordance with Annex 8 of the Convention on International Civil Aviation (Annex 8).
Failure to comply with ADs can result in significant legal consequences. Civil aviation offences under the Civil Aviation Act 1988 can lead to criminal charges, with penalties that include fines and imprisonment. The maximum penalty for serious offences can be substantial, reflecting the critical importance of air safety. Additionally, non-compliance with ADs can result in the grounding of aircraft, which can have severe operational and financial repercussions for operators. Civil penalties, such as fines, may also be imposed by CASA for breaches of ADs, underscoring the seriousness of maintaining airworthiness standards (section 98).
The legislative framework ensures that airworthiness directives are issued and enforced to maintain the highest safety standards in civil aviation. This includes the obligation for CASA to assess foreign ADs and issue Australian ADs as necessary, reflecting Australia’s commitment to international aviation safety standards. The consequences of non-compliance are severe, with both criminal and civil penalties available to enforce adherence to these critical safety measures.
