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/HILLER 12/3 affecting Hiller UH-12 series helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HILLER 12/3. The cancellation will become effective on 27 August 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 Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to ensure the safety and efficiency of civil aviation in Australia, provides the legislative framework under which airworthiness directives (ADs) are issued. The Act empowers the Governor-General to make regulations that align with the Act's objectives, particularly focusing on the safety of air navigation. The Civil Aviation Safety Regulations 1998, which are subsidiary legislation under the Act, further delineate the regulatory processes, including the issuance of ADs by the Civil Aviation Safety Authority (CASA). These directives, which are considered legislative instruments, serve as a critical mechanism for maintaining the continuing airworthiness of aircraft as per the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, assesses and implements these directives to ensure compliance with international standards and obligations.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legal framework for ensuring the safety of air navigation in Australia. Under these provisions, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) which are legislative instruments, enforceable under the Legislative Instruments Act 2003. These ADs mandate safety requirements for specific types of aircraft or aeronautical products, reflecting Australia’s commitments under Annex 8 to the Convention on International Civil Aviation. The State of Registry, such as CASA for Australia, is responsible for ensuring the continuing airworthiness of aircraft registered within its jurisdiction, and must comply with ADs issued by the State of Design. The scope of this legislation applies to all aircraft and aeronautical products operating within Australia, ensuring that safety standards are uniformly enforced across the nation. While the Act and its regulations apply broadly, specific exclusions or exemptions are not detailed in the provided text, and the application of the ADs is typically made without public consultation or regulatory impact assessment, as per the Office of Best Practice Regulation’s guidelines.
Key Provisions
The Civil Aviation Act 1988, in particular under section 98, empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation. This legislative authority is exercised through the Civil Aviation Safety Regulations 1998, where regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are not only critical for ensuring the continued safety and airworthiness of aircraft but are also recognised as legislative instruments under the Legislative Instruments Act 2003 (section 6) and are subject to disallowance under section 46A of the Acts Interpretation Act 1901.
Under the framework established by these regulations, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, according to Annex 8 to the Convention on International Civil Aviation. This entails providing necessary information to States of Registry to maintain airworthiness. The State of Registry, in turn, is tasked with implementing requirements to ensure the ongoing airworthiness of aircraft within its jurisdiction. Consequently, when the State of Design issues an AD for a type of aircraft registered in Australia, CASA is required to evaluate this information and, if necessary, issue a corresponding Australian AD to enforce the State of Design's requirements.
The obligations placed on entities governed by these regulations include a strict adherence to airworthiness directives issued by CASA. Aircraft operators and maintenance organisations must comply with the directives to ensure that their aircraft meet the necessary safety standards. This includes conducting required inspections, repairs, or modifications as specified in the ADs. Failure to comply with these directives can result in serious safety risks and potential legal consequences. CASA has the authority to take enforcement actions against non-compliance, which may include grounding aircraft, imposing fines, or taking other regulatory measures.
In terms of penalties and consequences for breaches, the Civil Aviation Safety Regulations 1998 do not explicitly outline specific penalties for non-compliance with ADs. However, non-compliance with ADs can lead to severe civil or criminal penalties under other sections of the Civil Aviation Act 1988. For instance, operating an aircraft that does not comply with ADs could result in fines, imprisonment, or both, depending on the severity of the violation. Additionally, CASA can impose administrative penalties, such as suspension or revocation of an aircraft operator's certificate or a pilot's license, further emphasising the importance of strict adherence to ADs for the safety of air navigation.
