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 2007-11-08 affecting Boeing model 727 aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B727/205, which will become effective on 5 July 2007.
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, enacted by the Australian Parliament, was introduced to address the need for a comprehensive framework governing civil aviation in Australia, with a particular emphasis on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations aimed at safeguarding air navigation, with regulation 39.001 specifically enabling the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) for certain types of aircraft or aeronautical products. These ADs, which are legislative instruments, are essential for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry under Annex 8 of the Convention on International Civil Aviation. In accordance with these international obligations, CASA issues Australian ADs in response to directives from the relevant State of Design, such as the United States FAA’s AD 2007-11-08 for Boeing model 727 aircraft, ensuring that Australian-registered aircraft meet international safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft and aeronautical products. These ADs, which are legislative instruments under section 6 of the Legislative Instruments Act 2003, aim to ensure the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. This Act applies to aircraft registered in Australia and mandates CASA to issue Australian ADs in response to airworthiness directives issued by the State of Design. For instance, following the issuance of AD 2007-11-08 by the United States Federal Aviation Administration (FAA) concerning Boeing model 727 aircraft, CASA issued Australian AD/B727/205, effective from 5 July 2007. This process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The issuance of these directives is conducted 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 Civil Aviation Act 1988.
Key Provisions
The main sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are subject to disallowance as per section 6 of the Legislative Instruments Act 2003.
The obligations under these regulations are primarily directed at ensuring the safety and airworthiness of aircraft. According to Annex 8 to the Convention on International Civil Aviation, the State of Design (in this case, the United States for Boeing 727 aircraft) holds the primary responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to States of Registry, such as Australia, to ensure that aircraft remain airworthy. As the State of Registry, CASA must assess the information provided by the State of Design and, if necessary, issue an Australian AD to enforce the requirements. For example, CASA has issued AD/B727/205 in response to the United States FAA's AD 2007-11-08, which became effective on 5 July 2007.
Compliance with ADs is mandatory for aircraft operators and owners in Australia. These directives provide detailed instructions on the actions required to maintain or restore airworthiness, such as inspections, repairs, or modifications. Failure to comply with an AD can result in severe consequences, including the grounding of the affected aircraft, which could lead to operational disruptions and potential safety risks. Operators must ensure that all ADs are implemented in a timely manner and that compliance is documented and reported to CASA as required.
Violations of the provisions in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to both civil and criminal penalties. Civil penalties may include fines for non-compliance with ADs, which can vary significantly depending on the severity and frequency of the breach. In more serious cases, CASA may take enforcement actions, including the suspension or revocation of an aircraft's certificate of airworthiness. Criminal penalties may apply for wilful or reckless disregard of safety regulations, potentially resulting in substantial fines and imprisonment. The exact penalties are determined by the nature of the offence and are subject to the provisions of the relevant legislation.
