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 issued AD 2007-07-07R1 affecting General Electric CF 34 series engines. The United States is the State of Design for this engine model. CASA has amended the equivalent Australian AD to AD/CF34/5 Amendment 3 which will become effective on 25 October 2007. This AD cancels and replaces the previous issue.
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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes a legislative framework aimed at ensuring the safety and efficiency of civil aviation in Australia. One of the critical aspects of this legislation is the regulation of airworthiness, which is managed through the issuance of airworthiness directives (ADs). These directives serve as a mechanism to address safety concerns and ensure compliance with international standards as outlined in the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further elaborate on the process by which ADs are issued, allowing the Civil Aviation Safety Authority (CASA) to mandate specific safety requirements for aircraft and aeronautical products. The overall objective of this regulatory approach is to maintain the highest safety standards in air navigation and to align Australian practices with international obligations and best practices.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation in Australia, with a particular focus on safety. Under section 98 of the Act, the Governor-General has the authority to make regulations that support the Act's objectives, specifically in relation to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, and they are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs serve to ensure compliance with international standards as set out in Annex 8 to the Convention on International Civil Aviation, where the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue corresponding Australian ADs to enforce these international directives on aircraft registered in Australia. This regulatory approach ensures that Australian aviation practices align with global safety standards, thereby facilitating international cooperation and safety in civil aviation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for issuing airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. Section 98 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901, subject to disallowance, and are governed by the Legislative Instruments Act 2003.
The obligations under this legislation primarily rest with CASA as Australia’s national airworthiness authority. When the State of Design, such as the United States for the General Electric CF 34 series engines, issues an AD, CASA must assess this information and, if appropriate, issue a corresponding Australian AD. This ensures that Australian aircraft meet the continuing airworthiness standards mandated by the State of Design. The State of Registry of an individual aircraft also bears the responsibility of ensuring the continuing airworthiness of that aircraft, in line with Annex 8 to the Convention on International Civil Aviation.
There are no explicit provisions within the text that detail offences, penalties, or consequences for non-compliance with these ADs. However, given the critical nature of airworthiness directives in ensuring aviation safety, non-compliance could potentially lead to severe safety risks and legal consequences. CASA, as the regulator, would likely enforce compliance through inspections, audits, and possibly fines or other enforcement actions against operators who fail to adhere to the mandated ADs. The potential penalties for non-compliance would depend on the specific circumstances and the severity of the breach, but they could include administrative fines, operational restrictions, or even grounding of non-compliant aircraft.
