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/AA-5/3 affecting Gulfstream AA-5 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-5/3. The cancellation will become effective on 4 June 2009. 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 legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act allows for the creation of regulations aimed at maintaining and enhancing the safety of air navigation, a critical aspect of ensuring public safety and the integrity of the national airspace. In 2009, the Civil Aviation Safety Regulations 1998 were amended through the issue of F2009L01939, which pertained to the cancellation of an existing airworthiness directive (AD) for the Gulfstream AA-5 model aircraft. This directive was cancelled by the Civil Aviation Safety Authority (CASA) following an assessment that the unsafe condition it addressed no longer existed. The cancellation was executed in line with Australia's obligations under the Convention on International Civil Aviation and did not require public consultation or a Regulatory Impact Statement. The Manager, Systems and New Technologies, within CASA's Airworthiness Engineering Group, issued this legislative instrument under the authority granted by the Act.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 pertain to the regulation of civil aviation safety in Australia, particularly concerning the issuance of airworthiness directives (ADs). The Act applies to the Civil Aviation Safety Authority (CASA) as the national airworthiness authority, and its scope extends to all aircraft and aeronautical products registered within Australia. The authority to issue ADs under regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to mandate specific safety requirements for kinds of aircraft or aeronautical products. These directives are legislative instruments, as per the Legislative Instruments Act 2003, and must align with Australia's commitments under the Convention on International Civil Aviation. The geographic reach of the Act is national, with CASA assessing and, if necessary, issuing ADs to ensure compliance with international standards. The ADs serve as a mechanism to maintain the continuing airworthiness of aircraft, with the State of Registry being responsible for ensuring these standards. Notably, the Act and its regulations do not require public consultation or a Regulatory Impact Statement for ADs, reflecting their technical and safety-focused nature.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides a framework for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act empowers the Governor-General to make regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. It is important to note that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003.
Under these provisions, CASA, as Australia’s national airworthiness authority, is responsible for assessing ADs issued by the State of Design and, if deemed necessary, issuing corresponding Australian ADs to ensure the continuing airworthiness of aircraft registered in Australia. This responsibility aligns with Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overall responsibility for the continuing airworthiness of an aircraft type and requires it to provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction.
The obligations imposed by the Act and Regulations on CASA and other parties include the timely assessment of ADs from the State of Design, the issuance of Australian ADs when necessary, and the cancellation of ADs when the unsafe conditions they address no longer exist. CASA must act in accordance with the requirements set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, ensuring that all measures taken are in the interests of safety. The cancellation of AD/AA-5/3 affecting Gulfstream AA-5 model aircraft, effective from 4 June 2009, is an example of CASA fulfilling its obligations under these provisions.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail offences or penalties for breaches related to ADs. However, the failure to comply with ADs could potentially lead to serious safety issues, which may result in enforcement actions under other sections of the Act or related legislation. Such actions could include fines, imprisonment, or both, depending on the nature and severity of the non-compliance. CASA has the authority to take enforcement actions against individuals or entities that fail to comply with ADs, ensuring that safety standards are maintained.
