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/LA-4/11 affecting Consolidated Aeronautics, Colonial LA-4 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/LA-4/11. The cancellation will become effective on 2 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, aims to ensure the safety and efficiency of civil aviation in Australia. The Act provides the framework for regulating the safety aspects of civil aviation and includes provisions for issuing airworthiness directives. Under section 98 of the Act, the Governor-General has the authority to make regulations necessary for the safety of air navigation, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives under regulation 39.001 of the Civil Aviation Safety Regulations 1998. This regulatory mechanism is integral to ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards as set out in Annex 8 to the Convention on International Civil Aviation. The issuance and cancellation of these directives are carried out by CASA, reflecting Australia's commitment to international obligations and ensuring that aircraft operating within Australia meet the highest safety standards. The authority to cancel an airworthiness directive, as in the case of AD/LA-4/11 affecting Consolidated Aeronautics, Colonial LA-4 series aeroplanes, is exercised by CASA to address specific safety concerns and maintain the integrity of Australia's civil aviation safety regime.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These regulations apply to all kinds of aircraft and aeronautical products registered within Australia and allow CASA to mandate specific safety measures and requirements. Such directives are crucial for maintaining the continuing airworthiness of aircraft and are issued in response to identified safety concerns. The ADs are legislative instruments and are subject to disallowance, reflecting their regulatory impact. The State of Design, typically the country where the aircraft is designed, holds primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, which is Australia in this context, ensures that the aircraft remains airworthy within its jurisdiction. CASA’s role includes assessing ADs issued by foreign States of Design and, where necessary, issuing corresponding Australian ADs. This ensures compliance with both national and international standards, as set out in Annex 8 to the Convention on International Civil Aviation. The process of issuing, amending, or cancelling ADs is governed by these regulations and involves CASA's assessment and decision-making authority, reflecting Australia’s commitment to international aviation safety standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 relevant to the issuance of airworthiness directives (ADs) are sections 98 and 39.001, respectively. Under section 98, the Governor-General has the authority to make regulations to ensure the safety of air navigation. Regulation 39.001 then allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments, meaning they are legislative instruments that require scrutiny under the Legislative Instruments Act 2003.
The Act and the regulations impose certain obligations on CASA and other entities. CASA, as Australia's national airworthiness authority, must assess airworthiness information provided by the State of Design, which has the overall responsibility for the continuing airworthiness of an aircraft type under Annex 8 to the Convention on International Civil Aviation. When a State of Design issues an AD, CASA must evaluate the information and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must also develop or adopt requirements to ensure the airworthiness of aircraft.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various penalties and consequences. While the specific offences and penalties are not detailed in the provided text, it is common for breaches of aviation safety regulations to result in significant fines, potential imprisonment, or both, depending on the severity of the breach. The specific penalties would be outlined in other sections of the legislation or related regulatory instruments.
