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/INST/17 affecting King K1 525 Indicators. CASA has assessed this AD and as a result has cancelled Australian AD/INST/17. The cancellation will become effective on 12 March 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 comprehensive legal framework for the regulation of civil aviation in Australia, addressing the need for a robust system to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations aimed at enhancing the safety of air navigation, with the Civil Aviation Safety Regulations 1998 further detailing these regulatory measures. Among these regulations is the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a critical tool for maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, is responsible for assessing information from the State of Design and issuing corresponding ADs to enforce these requirements within Australia.
In a specific case concerning the King K1 525 Indicators, CASA issued and subsequently cancelled Australian AD/INST/17, effective from 12 March 2009. The cancellation of this AD was due to the resolution of the unsafe condition it targeted, and no replacement AD was deemed necessary. The decision to cancel 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. As this cancellation aligned with Australia's international obligations, no public consultation was required, and the Office of Best Practice Regulation determined that no Regulatory Impact Statement was necessary for this AD cancellation.
Scope and Application
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 outline the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products to maintain airworthiness standards. ADs serve as a key mechanism for disseminating continuing airworthiness information as per Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design the overarching responsibility for the airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, is obligated to assess and potentially issue Australian ADs when required by the State of Design, ensuring compliance with international standards. The issuance of these directives is governed by specific regulations and does not necessitate public consultation or a Regulatory Impact Statement, reflecting their technical nature and the urgency of addressing safety concerns.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 focus on the issuance and management of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. This regulation highlights that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument as per section 6 of the Legislative Instruments Act 2003. The obligations under these provisions require CASA to assess information provided by the State of Design and, if necessary, issue Australian ADs to ensure compliance with safety standards.
Entities governed by these provisions have specific responsibilities. The State of Design, under Annex 8 to the Convention on International Civil Aviation, is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. This includes evaluating ADs issued by the State of Design and determining if an Australian AD is necessary. In the case of King K1 525 Indicators, CASA issued AD/INST/17, assessed the condition, and subsequently cancelled the directive, effective from 12 March 2009, as the unsafe condition no longer existed.
The Act and Regulations impose various obligations on the involved parties. For example, CASA must ensure that any unsafe conditions identified by the State of Design are addressed appropriately through the issuance of an Australian AD. The State of Registry must develop and enforce requirements that maintain the airworthiness of aircraft registered within its jurisdiction. Failure to comply with these obligations can lead to safety risks, potentially resulting in accidents or incidents. The issuing and enforcement of ADs are critical to maintaining safety standards in aviation, as they ensure that all parties are aware of and comply with the necessary safety measures.
There are significant consequences for breaches of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Failure to adhere to ADs or other airworthiness requirements can result in civil penalties. Under the Civil Aviation Act 1988, individuals or entities found in breach of the Act can face fines up to $165,000 for individuals and $825,000 for corporations. In addition to fines, there can be criminal penalties, including imprisonment for serious offences. Such breaches not only endanger public safety but also undermine the regulatory framework designed to protect the aviation industry and the public.
