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/RAD/53 affecting all Australian Domestic Distance Measuring Equipment (DME-A). CASA has assessed this AD and as a result has cancelled Australian AD/RAD/53. The cancellation will become effective on 9 April 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 ensure the safety of air navigation in Australia and to provide a legislative framework for the regulation of civil aviation. It empowers the Governor-General to make regulations for the purposes of the Act, which include the issuance of airworthiness directives (ADs) to maintain the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on the authority of the Civil Aviation Safety Authority (CASA) to issue ADs concerning aircraft and aeronautical products. This regulatory mechanism is crucial for maintaining the continuing airworthiness of aircraft in line with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Authority, acting as Australia’s national airworthiness authority, is tasked with assessing information from the State of Design and issuing Australian ADs when necessary. The AD/RAD/53 concerning Australian Domestic Distance Measuring Equipment (DME-A) was assessed and subsequently cancelled by CASA, as the unsafe condition it was addressing no longer exists, thus no replacement AD is required. This AD cancellation was made in accordance with Australia's obligations under the Convention on International Civil Aviation and did not require public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation as per section 98 of the Act. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. These ADs are critical for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Design provides necessary information to ensure airworthiness, while the State of Registry implements these requirements. In Australia, CASA assesses ADs issued by other states and, if necessary, issues corresponding Australian ADs. The recent cancellation of AD/RAD/53 for all Australian Domestic Distance Measuring Equipment (DME-A) reflects the dynamic nature of airworthiness management, and no public consultation was required as it aligns with Australia's international obligations. This process is overseen by the Manager, Systems and New Technologies, within CASA's Airworthiness Engineering Group, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations that serve the safety of air navigation, ensuring that all aviation activities within Australia adhere to stringent safety standards. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments as per subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. Essentially, ADs are formal documents that mandate safety measures for aircraft and aeronautical products, and their issuance is a critical tool for maintaining airworthiness across the aviation industry.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the overarching responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to the States of Registry to ensure that the aircraft can be safely operated. The State of Registry, on the other hand, is responsible for the specific aircraft within its jurisdiction and must establish requirements to maintain airworthiness. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, evaluates this information and, if necessary, issues an Australian AD. This ensures that Australian-registered aircraft comply with the safety directives issued by the State of Design.
An example of this process is evident in the case of AD/RAD/53, which affected all Australian Domestic Distance Measuring Equipment (DME-A). CASA has reviewed this directive and determined that the unsafe condition it addressed no longer exists. Consequently, Australian AD/RAD/53 has been cancelled, effective from 9 April 2009. No replacement AD is necessary, as the condition prompting the original directive has been resolved. Given the international obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required for this cancellation.
The issuing of an AD and its subsequent cancellation carry significant implications. Any failure to comply with an AD can result in serious consequences, including potential criminal or civil penalties. The Civil Aviation Safety Regulations 1998 outline various offences related to non-compliance with ADs, which can lead to hefty fines and, in severe cases, imprisonment. For instance, failure to adhere to an AD can result in fines of up to $100,000 for individuals and $500,000 for corporations, alongside other possible civil liabilities. The strict enforcement of these regulations underscores the importance of maintaining airworthiness and ensuring the safety of all aviation activities in Australia.
