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/DHC-1/6 affecting De Havilland DHC-1 (Chipmunk) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-1/6. The cancellation will become effective on 23 October 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, 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 provide a legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. As part of this legislative framework, the Civil Aviation Safety Regulations 1998 were also established, which permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that are designed to maintain the continuing airworthiness of aircraft, in line with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The objective of the ADs is to ensure that aircraft types meet the necessary safety standards as mandated by the State of Design and the State of Registry. The process of issuing and cancelling ADs, such as the recent cancellation of AD/DHC-1/6 for De Havilland DHC-1 (Chipmunk) model aeroplanes, is carried out by CASA, Australia's national airworthiness authority, in accordance with the legislative provisions and international obligations.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. The Act applies to any person or entity involved in the operation or maintenance of aircraft registered in Australia, including aircraft manufacturers, operators, and maintenance service providers. The geographic reach of the Act is national, with the Civil Aviation Safety Authority (CASA) as the regulatory body responsible for enforcing compliance across Australia. ADs are issued under regulation 39.001 of the Civil Aviation Safety Regulations 1998, and they constitute a legislative instrument as per the Legislative Instruments Act 2003. These directives are mandated by the Convention on International Civil Aviation, specifically Annex 8, which assigns the State of Design the responsibility for the continuing airworthiness of aircraft types, while the State of Registry ensures the airworthiness of individual aircraft. CASA, acting as Australia’s national airworthiness authority, is required to assess and, if necessary, issue Australian ADs to align with those issued by the State of Design. This process ensures that Australian-registered aircraft meet international safety standards.
Key Provisions
The Civil Aviation Act 1988 (sections 98) and Civil Aviation Safety Regulations 1998 (regulation 39.001) outline the authority of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). An AD is a legislative instrument under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. These directives are issued to address safety issues and ensure the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for ensuring airworthiness, while the State of Registry must implement the ADs to maintain the airworthiness of aircraft registered within its jurisdiction.
The obligations placed on the parties governed by this legislation are significant. CASA, as the national airworthiness authority, must assess any international ADs issued by the State of Design for aircraft types registered in Australia. If deemed necessary, CASA must then issue an Australian AD to enforce the safety requirements. This process ensures that all aircraft operating in Australia meet the necessary safety standards. The State of Registry is also responsible for implementing these ADs and ensuring that the aircraft under its jurisdiction comply with the specified safety measures.
Failure to comply with the airworthiness directives can result in serious consequences. The Act does not explicitly outline specific offences, penalties, or civil/criminal consequences for non-compliance with ADs. However, non-compliance with safety regulations generally can lead to severe repercussions, including fines, suspension or revocation of aircraft certificates, and potential criminal charges. The severity of penalties may vary depending on the specific circumstances and the degree of non-compliance. Ensuring adherence to ADs is crucial for maintaining the safety of air navigation in Australia.
