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 EASA has issued AD 2006-0232 affecting Airbus A330 Series aircraft. EASA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A330/66, which will become effective on 30 October 2006.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the safety and efficiency of civil aviation in Australia. It empowers the Governor-General to make regulations that serve the interests of air navigation safety, such as the Civil Aviation Safety Regulations 1998. These regulations delegate the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as per regulation 39.001. The ADs are considered legislative instruments under the Legislative Instruments Act 2003, and they play a crucial role in ensuring the continuing airworthiness of aircraft types, as mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design, such as the European Aviation Safety Agency (EASA), issues ADs, and CASA, as Australia’s national airworthiness authority, assesses and implements these directives as necessary. The issuance of AD/A330/66 by CASA, in response to EASA's AD 2006-0232, exemplifies this regulatory process aimed at maintaining the safety standards of aircraft within the Australian Register.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products, and these ADs are classified as legislative instruments under the Legislative Instruments Act 2003. The application of these ADs extends to the State of Registry of aircraft within Australia, which is responsible for ensuring the continuing airworthiness of aircraft under Annex 8 of the Convention on International Civil Aviation. In the case of ADs issued by foreign authorities, such as the European Aviation Safety Agency (EASA) for Airbus A330 Series aircraft, CASA is obligated to assess and, if necessary, issue corresponding Australian ADs. These ADs do not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and the international obligations underpinning their issuance.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998 (CASR) pertinent to airworthiness directives (ADs) are sections 39.001 and its subregulation 39.001(5) (Civil Aviation Safety Regulations 1998). Section 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and thus, they qualify as legislative instruments under the Legislative Instruments Act 2003. These provisions empower CASA to ensure the continuing airworthiness of aircraft registered in Australia by mandating requirements based on ADs issued by the State of Design or other relevant authorities.
The obligations imposed on parties by these regulations primarily rest on CASA and the State of Registry. CASA, as Australia's national airworthiness authority, must assess any ADs issued by the State of Design and determine if issuing an Australian AD is necessary. This involves evaluating the safety implications of the AD and ensuring that the mandated requirements align with Australia's safety standards. The State of Registry, which could be CASA for aircraft registered in Australia, is responsible for ensuring the continuing airworthiness of individual aircraft. This includes implementing the requirements outlined in ADs and ensuring compliance with these mandates to maintain air safety.
Breach of the requirements set out in an AD can lead to significant consequences. Although specific offences and penalties are not detailed in the provided text, non-compliance with ADs can result in severe civil or criminal penalties under aviation law. In Australia, the penalties for contravening regulations designed to ensure the safety of air navigation can include substantial fines and, in some cases, imprisonment. The severity of the penalty would depend on the nature and extent of the breach, as well as any resulting harm or risk to aviation safety. The overarching goal is to ensure that all stakeholders adhere strictly to the mandated requirements to maintain the highest standards of airworthiness and safety.
