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/S-76/48 affecting Sikorsky S-76A and S-76B series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/S-76/48. 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, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish and regulate the safety of air navigation within Australia, providing a legislative framework for the operation of aircraft and the safety of air travel. One of the mechanisms for ensuring the continuing airworthiness of aircraft is through the issuance of airworthiness directives (ADs), which are established under the Civil Aviation Safety Regulations 1998. Under this regulatory framework, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. These directives are designed to ensure that aircraft meet safety standards, and in compliance with Australia’s international obligations under the Convention on International Civil Aviation. The Civil Aviation Act 1988 empowers the Governor-General to make regulations that support these objectives, while CASA acts as the national airworthiness authority, responsible for assessing and implementing ADs that align with international standards and practices.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia, with a particular emphasis on the airworthiness of aircraft. Under section 98 of the Act, the Governor-General is empowered to make regulations that contribute to the safety of air navigation, with regulation 39.001 specifically granting the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under the Acts Interpretation Act 1901, and they are issued in accordance with international standards, particularly Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type. The State of Registry, in this case CASA as Australia’s national airworthiness authority, has the responsibility to assess this information and, if deemed necessary, issue corresponding Australian ADs. This regulatory framework ensures that the continuing airworthiness of aircraft registered in Australia is maintained to the highest safety standards.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. These regulations enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD is defined as a disallowable instrument under subregulation 39.001(5), and thus, it is considered a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. These directives serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft types as outlined in Annex 8 to the Convention on International Civil Aviation.
The State of Design, which is the country responsible for the design of an aircraft type, bears the overall responsibility for ensuring the aircraft's continuing airworthiness. This includes providing necessary information to the State of Registry, which is the country where the aircraft is registered. The State of Registry must then develop or adopt appropriate requirements to maintain the aircraft's airworthiness. In Australia, CASA, as the national airworthiness authority, evaluates any ADs issued by the State of Design for aircraft types registered in Australia. If deemed necessary, CASA issues corresponding Australian ADs to mandate the required actions for ensuring the safety of these aircraft.
Under the Convention on International Civil Aviation, CASA has the responsibility to assess and respond to ADs issued by the State of Design for aircraft types registered in Australia. For instance, CASA assessed and subsequently cancelled Australian AD/S-76/48, which affected Sikorsky S-76A and S-76B series helicopters. This cancellation was due to the unsafe condition no longer existing, and it became effective on 2 July 2009. No replacement AD was required as the identified issue had been resolved.
Breach of the requirements set forth in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various consequences. The specific offences, penalties, and civil or criminal implications depend on the nature and severity of the breach. For example, failure to comply with airworthiness directives can lead to significant safety risks and may result in regulatory action, fines, or other penalties as prescribed by the relevant regulations. It is crucial for all parties involved to adhere to these provisions to maintain the high safety standards required in civil aviation.
