CIVIL AVIATION ACT 1988
CIVIL AVIATION 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.
As a result of a request from industry, CASA has reviewed AD/S-76/8 Amendment 11. This AD previously contained the retirement lives for fatigue critical components of the helicopter, but these are now contained in the Airworthiness Limitations Section of the type’s maintenance manual. As compliance with the Airworthiness Limitations Section is mandatory, AD/S-76/8 Amendment 11 is no longer required, and has been cancelled.
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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the industry. Under this Act, the Governor-General is empowered to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. The Civil Aviation Regulations 1998 further elaborate on these provisions, with regulation 39.001 specifically allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are critical in maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. The policy objective behind issuing ADs is to comply with international obligations under the Convention on International Civil Aviation and to ensure that aircraft registered in Australia meet necessary safety standards.
Scope and Application
The Civil Aviation Regulations 1998, under section 39.001, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. These airworthiness directives are essential for maintaining the safety standards of aircraft and aeronautical products, aligning with Australia's obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design, and by extension CASA as Australia's national airworthiness authority, ensure the continuing airworthiness of aircraft on the Australian register. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess and, if necessary, issue an Australian AD to enforce the requirements stipulated by the State of Design. The process for issuing these directives is streamlined and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The ADs are issued by CASA under the authority granted by the Civil Aviation Act 1988, with the specific directive being made by the Section Head - Airframes, Airworthiness Standards Branch, Standards Division, in accordance with subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988 (sections 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, regulation 39.001(5) specifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and is a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. ADs are crucial for maintaining the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for ensuring the airworthiness of an aircraft type, while the State of Registry must adopt requirements to maintain the airworthiness of individual aircraft within its jurisdiction. In Australia, CASA must assess ADs issued by States of Design and, where necessary, issue corresponding Australian ADs to mandate compliance with the requirements of the State of Design.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and other parties are significant. CASA, as Australia’s national airworthiness authority, must carefully evaluate ADs from the State of Design and decide whether to issue corresponding Australian ADs. These ADs must then be enforced to ensure that all aircraft within Australia comply with the specified requirements. Additionally, the State of Registry, which includes CASA in Australia, is responsible for ensuring that individual aircraft meet continuing airworthiness standards. This includes implementing the requirements set out in Australian ADs and ensuring that all necessary maintenance and operational procedures are followed.
Violations of the requirements set out in ADs can lead to serious consequences. Although specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with airworthiness directives can result in significant civil or criminal penalties. The seriousness of these penalties underscores the importance of adhering to ADs, as they are designed to ensure the safety of air navigation and the public. CASA has the authority to take enforcement actions against parties that fail to comply with ADs, which could include fines, suspension of airworthiness certificates, or other regulatory actions. These measures are in place to uphold the high safety standards mandated by Australian aviation law.
The process for issuing ADs, as outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, also includes a review by the Office of Regulatory Review. This review ensures that ADs are necessary and do not require a Regulatory Impact Statement, which is particularly relevant given the international obligations under the Convention on International Civil Aviation. The AD/S-76/8 Amendment 11, for example, was reviewed and subsequently cancelled because the necessary information was already included in the aircraft's maintenance manual. This demonstrates CASA's commitment to ensuring that ADs are both effective and necessary, avoiding redundancy and unnecessary regulatory burden.
