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.
CASA issued AD/BEECH 23/18 Amdt 1, affecting Beech 18 model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 20 December 2007. No replacement AD is required, as the original unsafe condition is now covered by AD/GENERAL/74.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, was introduced to establish a comprehensive legal framework for civil aviation safety and to regulate the aviation industry within Australia. This Act grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. The objective of the Act is to protect the safety of air navigation, in line with international standards set by the Convention on International Civil Aviation. The authority to issue ADs is exercised by CASA, the national airworthiness authority, which is responsible for ensuring that all aircraft meet the required safety standards. The legislative process for ADs, including their disallowance and review, is detailed in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. This approach underscores the commitment to maintaining high safety standards in Australian civil aviation.
Scope and Application
The Civil Aviation Act 1988, as amended and enforced through the Civil Aviation Safety Regulations 1998, establishes a comprehensive framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act empowers the Governor-General to create regulations that support air safety, while regulation 39.001 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are integral to maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. Such directives are essential as they align with international standards set forth in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the overall airworthiness of an aircraft type and the State of Registry for the individual aircraft’s continuing airworthiness. In practice, CASA must evaluate ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. For instance, CASA issued AD/BEECH 23/18 Amdt 1 concerning Beech 18 model aircraft from 1972, which has now been cancelled due to the condition being covered by another directive. The cancellation process does not require public consultation as it reduces regulatory burden, and no Regulatory Impact Statement is mandated by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 (CASR) provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the CASR allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. This regulatory approach ensures that aircraft maintain their airworthiness and comply with safety standards. The AD is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003 and is subject to disallowance under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the ADs include ensuring that the State of Design provides necessary information for the continuing airworthiness of aircraft types, and that the State of Registry implements requirements to maintain airworthiness for individual aircraft. CASA, as the national airworthiness authority, must assess information from the State of Design and issue an Australian AD if necessary. This ensures that Australian-registered aircraft comply with international safety standards and maintain their airworthiness.
CASA has the authority to issue, amend, or cancel ADs as needed to address safety concerns. In the case of AD/BEECH 23/18 Amdt 1, CASA reviewed the directive and decided to cancel it, effective from 20 December 2007, as the unsafe condition it addressed is now covered by another AD, AD/GENERAL/74. The decision to cancel this AD was made without public consultation, as it reduces the regulatory burden, and the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement. The Manager, Airframes in the Airworthiness Engineering Branch, made this AD on behalf of CASA in accordance with subsection 84A(2) of the Act.
The breach of ADs can lead to significant civil and criminal consequences. Non-compliance with ADs can result in penalties for the aircraft owner or operator, including fines and potential grounding of the aircraft. Such actions may also lead to criminal charges and prosecution, particularly if non-compliance results in safety incidents or accidents. The exact penalties depend on the severity of the breach and the impact on aviation safety, but they can include substantial fines and imprisonment for individuals responsible for non-compliance.
