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 77/8, affecting Beech 77 model aircraft in 1981. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago.
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 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, with a particular focus on ensuring the safety of air navigation. This Act grants the Governor-General the authority to make regulations for the purposes of the Act, including the issuance of airworthiness directives (ADs), as stipulated in section 98. The Civil Aviation Safety Regulations 1998 further outline the regulatory mechanisms for ADs, establishing CASA's capacity to issue these directives for specific types of aircraft or aeronautical products. In line with international standards, ADs serve as a critical means of maintaining the continuing airworthiness of aircraft, with the State of Registry holding responsibility for ensuring these standards are met.
The Civil Aviation (Airworthiness Directives) Legislative Instrument, F2008L01739, was introduced to address the need for the cancellation of an outdated airworthiness directive (AD/BEECH 77/8) pertaining to Beech 77 model aircraft, originally issued by CASA in 1981. The decision to cancel this AD was made following a review process, recognising that all affected aircraft had already been inspected and modified as required. As the cancellation results in a reduction of regulatory burden and has been deemed not to require a Regulatory Impact Statement, no consultation with the Australian public was necessary. This legislative instrument was made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, applies to any person, entity, or industry involved in civil aviation within Australia. Specifically, the Act and Regulations pertain to the issuance of airworthiness directives (ADs), which are legislative instruments designed to ensure the safety of air navigation. The ADs apply to kinds of aircraft or aeronautical products and are issued by the Civil Aviation Safety Authority (CASA), Australia’s national airworthiness authority. The geographic reach of this legislation is national, with CASA responsible for implementing and enforcing ADs across the Commonwealth of Australia. The Act and Regulations mandate that the State of Registry, which in this case is Australia, must ensure the continuing airworthiness of aircraft registered within its jurisdiction, aligning with international standards set by ICAO Contracting States. There are no stated exclusions or exemptions within the scope of the ADs, and the thresholds for issuing or cancelling ADs are determined by CASA based on safety assessments and international standards. Subordinate instruments, such as the ADs themselves, extend the application of the Act by providing specific safety mandates that must be complied with by the relevant parties.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance and management of airworthiness directives (ADs) in Australia. Section 98 of the Act empowers the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA, as the national airworthiness authority, to evaluate and potentially issue Australian ADs when a State of Design issues a directive for aircraft types registered in Australia. This ensures that Australian aircraft meet international standards for airworthiness. The State of Registry, which is responsible for the individual aircraft’s continuing airworthiness, must also develop or adopt requirements to ensure compliance with ADs. The AD/BEECH 77/8, issued in 1981, is a specific example of such a directive that has now been reviewed and cancelled by CASA, effective from 3 July 2008.
There are no civil or criminal penalties associated with non-compliance with ADs, as failure to comply would typically be addressed under broader aviation safety regulations and could result in severe consequences such as aircraft grounding or revocation of airworthiness certificates. The cancellation of AD/BEECH 77/8, which eliminates regulatory burden without necessitating public consultation or a Regulatory Impact Statement, underscores the importance of regularly reviewing and updating ADs to maintain safety standards. The directive was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring the process is conducted with due authority and oversight.
