CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 French DGAC has issued AD F-2005-051 affecting AIRBUS A318, A319, and A320 model aircraft. France is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A320/178 which will become effective on 7 July 2005.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, 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 and to ensure the safety of air navigation. This Act empowers the Governor-General to make regulations, including those concerning airworthiness directives (ADs), in the interests of safety. The Civil Aviation Regulations 1998 further elaborate on the issuance of ADs, stipulating that the Civil Aviation Safety Authority (CASA) may issue such directives for specific kinds of aircraft or aeronautical products. The authority to issue ADs arises from Australia's commitment to international standards set by the Convention on International Civil Aviation, particularly the responsibility of the State of Design to ensure continuing airworthiness. CASA, as the national airworthiness authority, is tasked with assessing international ADs and issuing corresponding Australian ADs as necessary. The policy objective of this legislative framework is to maintain the highest safety standards in civil aviation, aligning with international obligations and ensuring that Australian aircraft meet global safety requirements.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for ensuring the safety of air navigation in Australia. Specifically, the Act authorises the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as a critical mechanism for ensuring the continuing airworthiness of aircraft, a responsibility ultimately borne by the State of Registry, while the State of Design provides the necessary information to support this process. The issuance of ADs, including those by CASA in response to directives from States of Design such as France, is mandated by international obligations under the Convention on International Civil Aviation, particularly Annex 8. As a result, these directives are issued without public consultation and do not require a Regulatory Impact Statement, reflecting their urgent and internationally coordinated nature.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments as per section 6 of the Legislative Instruments Act 2003. The ADs are pivotal for maintaining the continuing airworthiness of aircraft, a responsibility that rests with the State of Design, as stipulated in Annex 8 to the Convention on International Civil Aviation.
These ADs are essential tools for disseminating continuing airworthiness information, commonly used by International Civil Aviation Organization (ICAO) Contracting States. The State of Registry for a particular aircraft is tasked with ensuring the aircraft's continuing airworthiness and must develop or adopt requirements to that effect under Annex 8. When the State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must evaluate the information and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design. For instance, the French Directorate General for Civil Aviation (DGAC) issued AD F-2005-051 affecting AIRBUS A318, A319, and A320 model aircraft, and CASA subsequently issued Australian AD/A320/178, effective from 7 July 2005.
Under the Civil Aviation Act 1988, CASA’s authority to issue ADs arises from Australia's obligations under the Convention on International Civil Aviation and in response to ADs issued by the relevant State of Design. Consequently, no public consultation is required for such ADs, and the Office of Regulatory Review has concluded that they do not necessitate a Regulatory Impact Statement. The issuance of these ADs is governed by subsection 84A(2) of the Act and is executed by the Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA.
The Act and the accompanying regulations impose several obligations on the entities they govern. CASA, as the national airworthiness authority, must rigorously assess and respond to ADs issued by the State of Design. This involves evaluating the ADs to ensure that they align with Australian standards and issuing corresponding ADs where necessary. The State of Registry must also ensure that the aircraft under its purview adhere to the continuing airworthiness requirements, which may involve implementing specific maintenance, repair, or operational procedures as outlined in the ADs. These obligations ensure that all aircraft operating within Australian airspace meet the necessary safety standards.
Failure to comply with the ADs can lead to significant consequences. Civil aviation regulations are stringent to maintain high safety standards, and non-compliance can result in severe penalties. Under the Civil Aviation Act 1988, CASA has the authority to take enforcement actions against entities that fail to adhere to ADs. These actions can include fines, suspension or revocation of airworthiness certificates, and other administrative penalties. In severe cases, non-compliance can result in criminal charges, which may lead to imprisonment. The specific penalties for breaches can vary, but they are designed to enforce strict compliance with airworthiness directives to protect public safety.
