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 United States FAA has issued AD 2007-26-20 affecting Pratt and Whitney PW4000 series engines. The United States is the State of Design for these engines CASA has assessed this AD and has issued Australian AD/PW4000/14, which will become effective on 22 October 2009.
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, Future Technology and Regulatory Trends of the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to establish a comprehensive regulatory framework for the safety and efficiency of civil aviation in Australia, addresses the need for stringent controls over the airworthiness of aircraft and aeronautical products. As an integral part of this legislative framework, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. The issuance of these directives is authorised under section 98 of the Act and regulation 39.001 of the Regulations, reflecting the overarching objective of ensuring the safety of air navigation. In line with international obligations under the Convention on International Civil Aviation, particularly Annex 8, the State of Design retains responsibility for the continuing airworthiness of aircraft types, and CASA must mandate the requirements of such directives when appropriate, thereby fulfilling Australia's commitments under international aviation agreements.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998, as amended, provide the legislative framework for airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations aimed at ensuring the safety of air navigation, and regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs are issued in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. In response to such international obligations, CASA assesses relevant ADs issued by States of Design and may issue corresponding Australian ADs to ensure compliance with international safety standards. For instance, CASA has assessed a United States Federal Aviation Administration AD concerning Pratt and Whitney PW4000 series engines and has issued its own corresponding Australian AD/PW4000/14. This AD is effective from 22 October 2009, reflecting Australia's commitment to international aviation safety standards 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 establish the framework within which airworthiness directives (ADs) are issued and enforced in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the purposes of the Act, particularly concerning the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Acts Interpretation Act 1901 and are subject to disallowance. The issuance of ADs is governed by international standards set out in Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for the continuing airworthiness of an aircraft type to the State of Design and mandates that such states provide necessary information to States of Registry.
Entities subject to these regulations, particularly CASA, must ensure that they assess and, if necessary, issue ADs in line with international standards. When the State of Design issues an AD, such as AD 2007-26-20 by the United States Federal Aviation Administration (FAA) for Pratt and Whitney PW4000 series engines, CASA must evaluate this directive and, if appropriate, issue an Australian AD. This is evident in the issuance of Australian AD/PW4000/14, which CASA has mandated to become effective on 22 October 2009. As this process is driven by Australia’s international obligations and in response to directives from the relevant State of Design, there is no requirement for public consultation, and the Office of Regulatory Review has determined that such ADs do not necessitate a Regulatory Impact Statement.
The ADs issued under these regulations impose strict obligations on CASA and other relevant authorities to ensure that aircraft meet the required safety standards. Failure to comply with these ADs can have serious consequences. The legislation does not explicitly state the penalties for non-compliance; however, it is implied that breaches of these safety regulations could lead to significant civil or criminal penalties. The severity of these penalties would depend on the specific nature and impact of the non-compliance, as well as other applicable aviation laws and regulations. Ultimately, the aim of these provisions is to maintain the highest standards of air safety in Australia, in line with international obligations and best practices.
