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/ELECT/47 affecting B.F. Goodrich propeller de-icer terminal clamp assemblies fitted to Hartzell HC-B3TN and HC-B4TN series propellers. CASA has assessed this AD and as a result has cancelled Australian AD/ELECT/47. The cancellation will become effective on 12 February 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, with a strong focus on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. Under this authority, the Civil Aviation Safety Regulations 1998 were established, which among other things, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. Such ADs serve as legislative instruments, as per the Legislative Instruments Act 2003. The overarching goal of these regulations is to uphold the continuing airworthiness of aircraft in accordance with international standards set forth by the Convention on International Civil Aviation.
In the case of the airworthiness directive AD/ELECT/47, originally issued by CASA concerning B.F. Goodrich propeller de-icer terminal clamp assemblies on certain propellers, CASA assessed the directive and determined that the unsafe condition it addressed no longer existed. Consequently, AD/ELECT/47 was cancelled, with the cancellation taking effect on 12 February 2009. Given the directive's cancellation was due to Australia's obligations under the Convention on International Civil Aviation, no public consultation was required, and the Office of Best Practice Regulation deemed a Regulatory Impact Statement unnecessary. This AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for ensuring the safety of air navigation in Australia. Specifically, the Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, while the Regulations detail the process for issuing airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs, which are legislative instruments, are integral to maintaining the continuing airworthiness of aircraft and are issued by the Civil Aviation Safety Authority (CASA) as Australia’s national airworthiness authority. The ADs must align with international standards set forth in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must implement the necessary requirements to ensure the ongoing airworthiness of individual aircraft. The ADs serve as a primary mechanism for disseminating continuing airworthiness information globally, and CASA is tasked with assessing and, when necessary, issuing Australian ADs that reflect the mandates of the State of Design. The scope of this legislation extends to all persons and entities involved in the design, manufacturing, maintenance, and operation of aircraft registered in Australia, ensuring adherence to stringent safety standards.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 pertain to the issuance and cancellation of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products. This regulatory process ensures that any identified safety issues are addressed through mandatory directives. Subregulation 39.001(5) specifies that ADs are considered disallowable instruments, and thus, they must be reviewed and approved under the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA, as Australia’s national airworthiness authority, to assess ADs issued by the State of Design and determine if an Australian AD is necessary. This assessment ensures that Australian-registered aircraft meet international safety standards as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry is also responsible for the continuing airworthiness of each aircraft, which means they must implement the necessary requirements set forth by CASA. This includes complying with the ADs issued by CASA and ensuring that all safety measures are adhered to.
In terms of consequences for non-compliance, the Act does not explicitly state penalties for failure to adhere to ADs. However, non-compliance with safety regulations can lead to significant civil and criminal consequences. Civil penalties may include fines and other administrative sanctions, while criminal penalties can include imprisonment, particularly if non-compliance results in serious harm or fatalities. The severity of the penalty will depend on the nature and extent of the breach. Additionally, aircraft operators found in breach of ADs may face grounding of their aircraft until compliance is achieved, potentially disrupting operations and leading to financial losses.
