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 23/32, affecting Beech 23 model aircraft in 1976. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition has long ceased to exist.
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 governing civil aviation within Australia, addressing the need for a unified approach to the regulation of air navigation and aircraft safety. Enacted by the Australian Parliament, the Act empowers the Governor-General to make regulations for the purposes of the Act, ensuring the safety of air navigation. Under this legislative umbrella, the Civil Aviation Safety Regulations 1998 were also developed, providing specific safety regulations for civil aviation operations, including the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. The ADs serve as a mechanism for the Civil Aviation Safety Authority (CASA) to mandate safety requirements, aligning with international standards set by the International Civil Aviation Organization (ICAO).
In a specific instance, CASA issued an AD/BEECH 23/32 for Beech 23 model aircraft in 1976, which has now been cancelled by CASA due to the resolution of the original safety concern. The cancellation of this AD, effective from 17 January 2008, reflects the absence of any ongoing regulatory burden and was made without public consultation, as determined by the Office of Best Practice Regulation. This decision underscores CASA's role as the national airworthiness authority, ensuring that Australian aviation remains compliant with both national and international safety standards.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are legislative instruments that mandate actions to maintain the safety of air navigation. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness of an aircraft type with the State of Design, while the State of Registry is tasked with ensuring the ongoing airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, assesses information from the State of Design and issues corresponding ADs as necessary. In this instance, CASA issued AD/BEECH 23/32 for Beech 23 model aircraft in 1976, but has since decided to cancel it effective from 17 January 2008, as the original safety concern no longer exists, thus reducing the regulatory burden without the need for public consultation or a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the legislative framework provided by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the legal basis for the issuance of airworthiness directives (ADs) in Australia. Specifically, the Governor-General can make regulations under the Act to ensure the safety of air navigation, and the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, given their disallowable nature as per section 46A of the Acts Interpretation Act 1901. The State of Design is primarily responsible for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure the ongoing airworthiness of individual aircraft registered within its jurisdiction.
Under these regulations, CASA is obligated to review and assess any ADs issued by the State of Design that affect aircraft on the Australian Register. If an AD is deemed necessary, CASA will issue an Australian AD to enforce the required safety measures. For instance, CASA issued AD/BEECH 23/32 in 1976, addressing safety concerns related to the Beech 23 model aircraft. Following a review, CASA decided to cancel this AD, effective from 17 January 2008, as the original unsafe condition no longer existed. No consultation with the Australian public was required for this cancellation, as it reduces the regulatory burden. Moreover, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
Violating the provisions of an AD can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in various civil penalties. The severity of the penalty may depend on the nature of the breach, with potential fines ranging up to a substantial amount. Furthermore, repeated or severe breaches can lead to more severe penalties, including imprisonment, reflecting the seriousness of ensuring aviation safety. CASA has the authority to enforce these regulations and can take legal action against individuals or entities that fail to comply with the mandated safety requirements.
