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
The Civil Aviation Safety Authority or its predecessors issued AD/DHC-1/18 affecting De Havilland DHC-1 (Chipmunk) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-1/18. 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, establishes the framework for ensuring the safety of air navigation within Australia. Under this Act, the Governor-General has the authority to create regulations that serve the interests of aviation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further delineate CASA’s responsibilities in issuing ADs, which are legislative instruments aimed at maintaining the continuing airworthiness of aircraft and aeronautical products. These directives are integral to fulfilling Australia's commitments under Annex 8 to the Convention on International Civil Aviation, where the State of Design and State of Registry share responsibilities for ensuring aircraft safety. The recent cancellation of AD/DHC-1/18, concerning De Havilland DHC-1 (Chipmunk) model aeroplanes, reflects CASA's ongoing commitment to safety and compliance with international standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide the regulatory framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, with the overarching goal of maintaining and enhancing aviation safety standards. The ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are formulated in compliance with the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of States of Design and States of Registry regarding the continuing airworthiness of aircraft. The ADs serve as crucial mechanisms for communicating necessary safety measures to ensure the continued safe operation of aircraft. The Civil Aviation Safety Authority, acting on behalf of Australia's obligations under international conventions, has the authority to issue, amend, or cancel ADs as required, reflecting changes in safety assessments and the resolution of identified unsafe conditions.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) of the Regulations clarifies that an AD is a disallowable instrument, making it a legislative instrument under section 6 of the Legislative Instruments Act 2003. This regulatory framework is designed to ensure that aircraft maintain their airworthiness and comply with international standards set by the Convention on International Civil Aviation, particularly through Annex 8.
The obligations imposed by this legislation on the parties involved are substantial. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. Conversely, the State of Registry is tasked with developing or adopting requirements to ensure the continuing airworthiness of individual aircraft registered within its jurisdiction. This dual responsibility ensures a comprehensive approach to maintaining airworthiness standards. CASA, as the regulatory authority in Australia, is responsible for issuing ADs when necessary to address safety concerns. In this context, CASA issued AD/DHC-1/18 for De Havilland DHC-1 (Chipmunk) model aeroplanes, which was subsequently cancelled due to the resolution of the identified unsafe condition.
Breaches of the Civil Aviation Safety Regulations 1998, including non-compliance with airworthiness directives, can lead to significant legal consequences. While the specific offences and penalties are not detailed in the provided text, it is common for regulatory breaches in this context to result in civil penalties, including fines, and potentially criminal charges in cases of gross negligence or deliberate non-compliance. The maximum penalties can vary depending on the severity of the breach and are outlined in the relevant sections of the Civil Aviation Act 1988 and other associated regulations. The detailed consequences would typically be found in the relevant sections of the Act and would include both financial penalties and potential imprisonment for serious offences.
