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/CESSNA 336/1 affecting Cessna 336 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 336/1. The cancellation will become effective on 8 May 2008. 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, serves to establish and regulate civil aviation safety in Australia. The Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Under this framework, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments, play a crucial role in maintaining the continuing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is responsible for assessing and, if necessary, issuing Australian ADs to enforce the requirements of the State of Design when such directives are issued by the designing state. In the case of AD/CESSNA 336/1, CASA has cancelled the Australian directive due to the resolution of the unsafe condition, reflecting Australia’s commitment to international civil aviation obligations and ensuring the safety and compliance of aircraft within the Australian Register.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, such as the Civil Aviation Safety Regulations 1998, establish a comprehensive framework for ensuring the safety of air navigation in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) that pertain to specific types of aircraft or aeronautical products. These directives are instrumental in maintaining the continuing airworthiness of aircraft, ensuring they meet necessary safety standards. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and the State of Registry concerning the maintenance of airworthiness. The State of Design issues ADs for aircraft types, and CASA, as Australia's national airworthiness authority, is responsible for assessing these directives and, where appropriate, issuing corresponding Australian ADs. This regulatory approach ensures that all aircraft registered in Australia comply with stringent safety requirements. The cancellation of AD/CESSNA 336/1, affecting Cessna 336 aircraft, exemplifies CASA’s role in monitoring and updating ADs to reflect current safety conditions. The cancellation of this particular AD is a direct result of the obligations under the Convention on International Civil Aviation, and it has been implemented without public consultation, as determined by the Office of Best Practice Regulation, which has also concluded that ADs do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. These ADs are tools used to ensure the continuing airworthiness of aircraft types and aeronautical products, and they are issued by the Civil Aviation Safety Authority (CASA). Specifically, section 39.001(5) of the Regulations classifies ADs as disallowable instruments, and thus, as legislative instruments under the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations require the State of Design to maintain responsibility for the continuing airworthiness of an aircraft type, providing necessary information to States of Registry to ensure safety. The State of Registry, such as Australia, must then adopt or develop requirements to ensure the airworthiness of individual aircraft. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess this information and, if necessary, issue an Australian AD. The example provided involves AD/CESSNA 336/1, which was issued for Cessna 336 aircraft and subsequently cancelled by CASA on 8 May 2008 due to the unsafe condition no longer existing.
The Act and Regulations do not mandate public consultation for the cancellation of ADs, as this action is driven by international obligations under the Convention on International Civil Aviation. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD cancellation process was carried out by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can result in significant legal consequences. Operators who fail to comply with an AD may face enforcement actions, including fines, suspension or revocation of airworthiness certificates, and potential criminal charges for serious violations. The specific penalties are outlined in the Civil Aviation Regulations 1988, which can impose fines up to a maximum of $105,000 for each flight or operation in non-compliance, along with other civil and criminal penalties for more serious breaches.
