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 Civil Aviation Safety Authority or its predecessors issued AD/AC-100/16 affecting all models of S.L. Industries Commander 100 and Volair 10 series aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/AC-100/16. The cancellation will become effective on 28 August 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 and New Technologies, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations in the interests of aviation safety, including the issuance of airworthiness directives (ADs) as stipulated in the Civil Aviation Safety Regulations 1998. These regulations, which are legislative instruments under the Acts Interpretation Act 1901, enable the Civil Aviation Safety Authority (CASA) to mandate requirements for maintaining the airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The authority to issue ADs stems from CASA’s responsibility to ensure the continuing airworthiness of aircraft registered in Australia, which involves assessing and acting on directives issued by the aircraft's State of Design. In this particular instance, CASA has cancelled an Australian airworthiness directive concerning specific models of S.L. Industries Commander 100 and Volair 10 series aircraft, effective from 28 August 2008, due to the resolution of the previously identified unsafe condition, without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives, which are legislative instruments, mandate compliance with continuing airworthiness requirements and are issued under the responsibility of the State of Design and the State of Registry in accordance with international standards set by the International Civil Aviation Organization (ICAO). In Australia, CASA, as the national airworthiness authority, assesses information from the State of Design and, if necessary, issues Australian ADs to enforce the requirements. The Act and Regulations apply to all entities involved in the registration, design, manufacture, maintenance, and operation of aircraft within Australia, including aircraft manufacturers, operators, maintenance providers, and aviation authorities. ADs are applicable nationally and align with international obligations under ICAO’s Annex 8. Notably, ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and are subject to the Legislative Instruments Act 2003. The specific AD/AC-100/16, which was issued for certain models of S.L. Industries Commander 100 and Volair 10 series aircraft, has been cancelled by CASA due to the resolution of the unsafe condition it addressed, without the need for a replacement directive.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Act, the Governor-General is empowered to make regulations for the safety of air navigation, and regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specified types of aircraft or aeronautical products (s. 39.001). The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and thus are legislative instruments as per section 6 of the Legislative Instruments Act 2003 (s. 39.001(5)). This legislative basis underscores the importance of ADs in maintaining the safety and airworthiness of aircraft within Australia.
Obligations under this legislation fall primarily on CASA as the national airworthiness authority. When a State of Design, the entity responsible for the aircraft type's airworthiness, issues an AD, CASA must evaluate this information. If deemed appropriate, CASA may then issue an Australian AD to enforce the requirements outlined by the State of Design. The State of Registry, which is responsible for the individual aircraft's airworthiness, must also adhere to and enforce the ADs issued by CASA to ensure compliance with safety standards. These obligations ensure that all stakeholders are aware of and comply with the necessary safety measures.
Failure to comply with ADs can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can be considered an offence, potentially leading to criminal charges. The specific penalties for such offences are not detailed in the provided text, but it is known that CASA has the authority to enforce compliance through various means, including fines and other administrative actions. Additionally, failure to adhere to ADs may also result in civil consequences, such as the grounding of aircraft, which could impact the operations and reputation of the entities involved.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for the issuance and enforcement of ADs in Australia. CASA's role in assessing and issuing ADs, along with the obligations placed on the State of Registry and other stakeholders, ensures that safety standards are maintained. While the specific penalties for non-compliance are not detailed in the text, the potential for both criminal and civil consequences underscores the importance of adhering to these directives.
