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/AUS/7 affecting Auster/Beagle A.61 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AUS/7. The cancellation will become effective on 30 July 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to address the need for comprehensive regulations to ensure the safety of air navigation in Australia. This Act empowers the Governor-General to create regulations that contribute to air navigation safety, with the Civil Aviation Safety Regulations 1998 further detailing these provisions. Specifically, regulation 39.001 of these Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, ensuring that these directives align with international standards set by the International Civil Aviation Organization (ICAO). These ADs are critical for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, with CASA playing a pivotal role in enforcing these standards within Australia.
In accordance with international obligations, CASA has the authority to issue and cancel ADs as necessary, ensuring that Australian aviation remains compliant with global safety standards. The cancellation of AD/AUS/7 for Auster/Beagle A.61 series aeroplanes, effective from 30 July 2009, exemplifies this regulatory approach. Given that this cancellation is a direct result of Australia’s obligations under the Convention on International Civil Aviation, no public consultation was deemed necessary. Additionally, the Office of Best Practice Regulation has concluded that ADs do not require a Regulatory Impact Statement, streamlining the process for CASA to act swiftly in response to safety concerns.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework under which airworthiness directives (ADs) are issued in Australia, ensuring the safety and airworthiness of aircraft. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft, a responsibility that rests with the State of Registry, which in Australia is CASA. In accordance with international standards under Annex 8 to the Convention on International Civil Aviation, CASA evaluates ADs issued by the State of Design and, if necessary, issues corresponding Australian ADs to enforce these safety measures. The issuance and cancellation of ADs are critical processes, and in this instance, Australian AD/AUS/7 for Auster/Beagle A.61 series aeroplanes has been cancelled as of 30 July 2009, following the resolution of the unsafe condition that originally prompted its issuance. This cancellation reflects Australia's adherence to international obligations and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a regulatory framework for ensuring the safety of air navigation. Section 98 of the Act authorises the Governor-General to make regulations for safety purposes, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. An AD, as outlined in subregulation 39.001(5), is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and thus is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003.
In practical terms, an airworthiness directive serves as a formal communication from CASA to aircraft operators and owners, mandating specific actions to ensure that an aircraft remains airworthy. This includes compliance with maintenance schedules, installation of modifications, or adherence to operational limitations. Such directives are issued to address identified safety issues or to mandate the correction of unsafe conditions. The State of Design, typically the manufacturer of the aircraft, is responsible for issuing ADs, while the State of Registry, which could be Australia in this context, is responsible for implementing them. CASA, as Australia's national airworthiness authority, has the duty to assess foreign ADs and, if necessary, issue corresponding Australian ADs to align with international safety standards.
Under these regulations, CASA issued AD/AUS/7 for Auster/Beagle A.61 series aeroplanes, but has subsequently cancelled it. This cancellation, effective from 30 July 2009, was made due to the resolution of the unsafe condition that initially prompted the directive. No replacement AD is required as the underlying issue no longer exists. This cancellation was executed in accordance with Australia’s obligations under the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry regarding the continuing airworthiness of aircraft. The AD was cancelled without public consultation, as determined by the Office of Best Practice Regulation, which found that such directives do not necessitate a Regulatory Impact Statement.
The issuance and cancellation of airworthiness directives are serious matters with significant legal implications. Failure to comply with an AD can result in serious consequences, including fines and potential criminal charges for those responsible for the aircraft's maintenance and operation. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can be prosecuted as an offence, with penalties that may include substantial fines for individuals and corporations. Additionally, CASA has the authority to take enforcement actions such as grounding non-compliant aircraft, which can have severe operational and financial repercussions for operators.
