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 340/1 affecting Cessna 340 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 340/1. The cancellation will become effective on 5 June 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 framework for the regulation of civil aviation in Australia, with the overarching goal of ensuring the safety and efficiency of air navigation. This legislation empowers the Governor-General to make regulations necessary for the safety of air navigation, which includes the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998 further detail the processes and responsibilities associated with airworthiness directives, establishing the Civil Aviation Safety Authority (CASA) as the body responsible for issuing such directives. These directives serve as a mechanism for ensuring the continuing airworthiness of aircraft, aligning with international standards as set out in Annex 8 to the Convention on International Civil Aviation. This legislative structure enables CASA to mandate safety requirements, cancel directives when conditions change, and thereby uphold the high safety standards required in the aviation industry.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework for the regulation of airworthiness directives (ADs) in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs concerning specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives are legislative instruments, as outlined under section 6 of the Legislative Instruments Act 2003 and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs are a reflection of Australia's commitment to the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type and mandates the provision of necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, is responsible for assessing ADs issued by States of Design and, if necessary, issuing Australian ADs to enforce the required safety measures. This process ensures that all aircraft registered in Australia meet the continuing airworthiness standards set forth by international agreements.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are the primary legislative instruments governing aviation safety in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to issue regulations that promote the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument under the Legislative Instruments Act 2003.
The obligations and requirements imposed by the Act and the Regulations on the parties involved are significant. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure continuing airworthiness to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. CASA, as Australia’s national airworthiness authority, has the responsibility to assess information from the State of Design and, if necessary, issue an Australian AD to mandate the required safety measures. For instance, CASA assessed and subsequently cancelled Australian AD/CESSNA 340/1 for Cessna 340 aircraft, determining that the unsafe condition no longer existed, thus eliminating the need for a replacement AD.
In terms of potential breaches and consequences, the Act and the Regulations do not explicitly outline specific offences, penalties, or civil/criminal consequences for failing to comply with ADs. However, non-compliance with ADs could potentially lead to serious safety issues, resulting in investigations, fines, or other regulatory actions by CASA. While the Act and the Regulations do not specify maximum penalties for non-compliance with ADs, the overarching goal is to ensure the safety of air navigation, and failure to adhere to ADs could lead to severe repercussions, including grounding of aircraft, legal actions, and other regulatory measures deemed necessary by CASA.
