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 2006-0300 affecting Eurocopter AS 332 L1 model aircraft. The EASA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/S-PUMA/64, Amendment 1, which will become effective on 15 February 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 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 Parliament of Australia, was introduced to regulate civil aviation in the interests of safety and efficiency. The Act provides the framework for the regulation of air navigation, aircraft, and related activities, ensuring the safety and security of air travel. One of the key mechanisms for ensuring airworthiness under this Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), as authorised by regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments that CASA issues to mandate compliance with safety standards for specific types of aircraft or aeronautical products. The policy objective is to align with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for continuing airworthiness. CASA, as Australia’s national airworthiness authority, evaluates ADs issued by foreign authorities and, where necessary, issues corresponding Australian ADs to ensure compliance and safety within the Australian Register.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the framework for airworthiness directives (ADs) which are legislative instruments issued to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. These directives are a crucial mechanism for maintaining the continuing airworthiness of aircraft, aligning with international obligations under Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA for Australia, must implement or adopt the necessary requirements to ensure compliance. This legislation applies to aircraft registered in Australia and to entities involved in the operation and maintenance of these aircraft. The geographic reach of this Act is national, as it pertains to the implementation of international standards within Australia’s jurisdiction. Notably, no public consultation is required for the issuance of ADs, and they are not subject to a Regulatory Impact Statement, reflecting their technical nature and the immediacy of safety concerns they address.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework within which airworthiness directives (ADs) are issued. 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 allows the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. This regulatory power is reinforced by subregulation 39.001(5), which designates ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are centred around ensuring the continuing airworthiness of aircraft. The State of Design, which is responsible for the initial design and certification of an aircraft type, must provide necessary information to ensure its airworthiness. This obligation is detailed in Annex 8 to the Convention on International Civil Aviation. Correspondingly, the State of Registry, which registers and oversees individual aircraft, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. In practice, when the State of Design issues an AD for an aircraft type registered in Australia, CASA must evaluate this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design.
The Civil Aviation Safety Regulations 1998 impose specific requirements on CASA when it issues ADs. For example, CASA must assess any AD issued by the State of Design and, if necessary, issue a corresponding Australian AD to mandate the required safety measures. This process is exemplified by the issuance of Australian AD/S-PUMA/64, Amendment 1, in response to EASA's AD 2006-0300 for Eurocopter AS 332 L1 model aircraft. The AD became effective on 15 February 2007, replacing the previous issue. Given that the AD is issued due to Australia’s obligations under the Convention on International Civil Aviation and in response to an AD raised by the relevant State of Design, no public consultation was required. Furthermore, the Office of Regulatory Review has determined that ADs do not necessitate a Regulatory Impact Statement.
Failure to comply with the requirements of an AD can lead to serious consequences. While the Act and the Regulations do not explicitly outline specific offences or penalties for non-compliance, the issuance of an AD is a legal mandate that must be adhered to. Non-compliance can result in the grounding of aircraft, potential legal action, and severe penalties under other aviation-related legislation. The seriousness of these consequences underscores the importance of strict compliance with ADs to maintain the highest standards of aviation safety.
