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 US FAA has issued AD 73-07-01 affecting Convair 340 and 440 model aircraft. The USA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CONVAIR/9, which will become effective on 11 May 2006.
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, Airframes 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 Commonwealth Parliament, is a foundational piece of legislation that governs civil aviation in Australia, with the primary aim of ensuring the safety of air navigation. This Act provides the authority for the issuance of regulations, including airworthiness directives (ADs), to maintain and ensure the continuing airworthiness of aircraft. Section 98 of the Act allows the Governor-General to make such regulations, which are designed to enhance aviation safety and comply with international standards. The Civil Aviation Safety Regulations 1998 further elaborate on the implementation of these directives, with regulation 39.001 specifically addressing the issuance of ADs for various types of aircraft or aeronautical products. These ADs are legislative instruments that must be assessed and, if necessary, adopted by the Civil Aviation Safety Authority (CASA) to ensure that Australian-registered aircraft meet international safety standards and obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) in Australia. According to section 98 of the Act, the Governor-General can make regulations necessary for the safety of air navigation, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs are integral to ensuring the continuing airworthiness of aircraft, with the State of Design having primary responsibility as per Annex 8 of the Convention on International Civil Aviation. When the State of Design issues an AD, CASA must assess it and, if necessary, issue an Australian AD to enforce the requirements for aircraft registered in Australia. The issuance of ADs such as AD/CONVAIR/9, in response to AD 73-07-01 from the US Federal Aviation Administration, is made in compliance with international obligations and without public consultation or the need for a Regulatory Impact Statement. This process is overseen by CASA and executed by authorised personnel within the Manufacturing, Certification and New Technologies Office.
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 kinds of aircraft or aeronautical products. These directives are mandated to ensure the safety of air navigation, aligning with the overarching aim of the Civil Aviation Act 1988 (section 98). In the case of foreign ADs, such as the one issued by the US Federal Aviation Administration (FAA) for the Convair 340 and 440 models, CASA evaluates the directive and, if necessary, issues a corresponding Australian AD. The Australian AD/CONVAIR/9, effective from 11 May 2006, is an example of this process, responding to the US FAA’s AD 73-07-01. The obligation to issue such ADs stems from Australia's commitments under the Convention on International Civil Aviation, particularly Annex 8, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry.
The obligations imposed by these regulations are significant for both CASA and the entities it regulates. CASA, as the national airworthiness authority, must meticulously assess foreign ADs and, if appropriate, issue their own directives to ensure compliance with Australian safety standards. For aircraft operators and owners, compliance with these ADs is mandatory; they must adhere to the specified requirements to maintain the airworthiness of their aircraft. This includes conducting necessary inspections, repairs, or modifications as outlined in the ADs. Failure to comply can result in severe consequences, including the grounding of aircraft, which could impede flight operations and potentially lead to safety hazards.
Breaching the provisions of the Civil Aviation Safety Regulations 1998 can have serious legal ramifications. For instance, non-compliance with ADs can result in penalties, including fines and imprisonment, as stipulated under section 93 of the Civil Aviation Act 1988. The maximum penalties for contravening these regulations can be substantial, reflecting the critical nature of air safety. Additionally, operators found in breach of ADs may face further enforcement actions, such as suspension or revocation of their air operator’s certificate, thereby affecting their ability to conduct commercial air operations. The stringent enforcement of these regulations underscores the importance of adhering to the mandated safety standards to protect both the public and the aviation industry.
