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/HU 269/102 Amendment 1 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/102 Amendment 1. The cancellation will become effective on 7 May 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 Parliament of Australia, provides the framework for ensuring the safety of civil aviation within the country. The Act was introduced to address the need for comprehensive legislation governing the safety and regulation of air navigation. Under section 98 of this Act, the Governor-General has the authority to make regulations aimed at maintaining the safety of air navigation. In conjunction with the Civil Aviation Safety Regulations 1998, the Act allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The issuance of these directives is intended to ensure the continuing airworthiness of aircraft registered in Australia, aligning with the international obligations under Annex 8 to the Convention on International Civil Aviation. CASA, as the national airworthiness authority, assesses information from the State of Design and may issue corresponding Australian ADs to enforce necessary safety measures.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs are legislative instruments and are issued in accordance with Australia’s obligations under the Convention on International Civil Aviation. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to the State of Registry. CASA, acting as Australia’s national airworthiness authority, assesses this information and, if deemed appropriate, issues an Australian AD to enforce the requirements set by the State of Design. In the case of AD/HU 269/102 Amendment 1, which affected Schweizer (Hughes) 269 series Helicopters, CASA cancelled the directive as the unsafe condition it addressed no longer existed. This cancellation was made without public consultation and does not require a Regulatory Impact Statement, in line with the determination of the Office of Best Practice Regulation.
Key Provisions
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the Governor-General and the Civil Aviation Safety Authority (CASA) have the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 98 of the Act and regulation 39.001 of the Regulations empower CASA to issue these directives, which are considered legislative instruments under the Legislative Instruments Act 2003. ADs serve as crucial tools for ensuring the continuing airworthiness of aircraft, mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for maintaining an aircraft type’s airworthiness. The State of Registry, in this case, CASA, must then assess and implement these directives to ensure compliance with safety standards.
The obligations imposed by these provisions require CASA to closely monitor and respond to ADs issued by the State of Design, particularly when these relate to aircraft on the Australian Register. CASA must evaluate the necessity and appropriateness of issuing corresponding Australian ADs, ensuring that the safety and airworthiness standards set by international conventions are met domestically. This involves a thorough review of the information provided by the State of Design, assessing the potential impact on Australian-registered aircraft, and determining the appropriate course of action, which may include issuing, modifying, or cancelling ADs as circumstances dictate.
Failure to comply with ADs or any neglect in fulfilling the obligations under the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 can result in significant legal consequences. Entities or individuals who do not adhere to the mandated requirements may face civil penalties, including fines, and criminal charges. The severity of the penalties can vary depending on the nature and extent of the breach, with potential maximum penalties outlined in relevant sections of the Act and Regulations. These measures are enforced to uphold the highest standards of aviation safety and to protect the public from the risks associated with non-compliance.
