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/CESSNA 400/94 affecting Cessna 425 model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 25 September 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework for civil aviation in Australia, addressing the need for a coordinated approach to aviation safety, efficiency, and regulatory oversight. Under this Act, the Governor-General has the authority to make regulations that serve the interests of air navigation safety. One such regulation is the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Registry for individual aircraft and the State of Design for aircraft types. The Civil Aviation Safety Regulations 1998 stipulate that ADs are disallowable instruments and, therefore, legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs align with the standards set by Annex 8 to the Convention on International Civil Aviation, ensuring international consistency in airworthiness requirements. The authority to issue and cancel ADs is exercised by CASA, reflecting Australia's commitment to international obligations and the imperative to address safety concerns promptly and effectively.
Scope and Application
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, with the Civil Aviation Safety Authority (CASA) authorised to issue such directives under regulation 39.001. These ADs are legislative instruments, subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve to mandate continuing airworthiness requirements for specific types of aircraft or aeronautical products registered in Australia, 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 as Australia’s national airworthiness authority, ensures compliance with these requirements. The issuance, assessment, and cancellation of ADs are integral to maintaining the safety standards of civil aviation within Australia, and such actions are taken in accordance with the outlined regulations and international agreements.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as per subregulation 39.001(5), are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901. Annex 8 of the Convention on International Civil Aviation mandates that the State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess this information and, if necessary, issue an Australian AD to enforce the requirements.
These ADs are essential tools for ensuring the ongoing safety and airworthiness of aircraft. CASA is responsible for assessing and potentially issuing Australian ADs when foreign ADs affect aircraft registered in Australia. For instance, CASA issued an AD affecting Cessna 425 model aircraft, which has now been cancelled due to the resolution of the unsafe condition identified. This cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation and will become effective on 25 September 2008. Notably, no consultation with the Australian public was required for this cancellation, and the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
Entities and individuals governed by these regulations, particularly those involved in the operation and maintenance of aircraft, must adhere to any ADs issued by CASA. These directives are binding and must be followed to ensure compliance with safety standards. Failure to comply with an AD can result in significant consequences, including fines, penalties, or criminal charges, depending on the severity of the non-compliance. For example, under the Civil Aviation Act 1988, an entity may face fines of up to $21,000 for each day an AD is contravened. Additionally, CASA has the authority to take enforcement actions, such as grounding aircraft or imposing operational restrictions, to ensure compliance with airworthiness standards. It is crucial for all stakeholders to stay informed about ADs and ensure that their operations comply with these safety directives.
