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 UK CAA has issued AD 003-03-97 affecting BAe Jetstream 4100 model aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/J4100/12, which will become effective on 20 February 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for civil aviation in Australia, focusing primarily on the safety and regulation of air navigation. The Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, as seen in the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, which are crucial for maintaining the continuing airworthiness of aircraft types as mandated by international standards under Annex 8 to the Convention on International Civil Aviation. The policy objective of these regulations is to ensure that aircraft registered in Australia comply with international safety standards, thus facilitating safe and efficient air navigation within and beyond Australia's borders. The issuing of ADs is an integral part of this framework, reflecting Australia’s commitment to international civil aviation safety protocols.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia. Under this legislative structure, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are designed to maintain the continuing airworthiness of aircraft, a responsibility that extends to both the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. The ADs serve as a crucial mechanism for disseminating necessary information to ensure the safety standards are upheld across all aircraft types registered in Australia. The application of these directives is mandated by Australia's international obligations and the need to comply with regulations set forth by the relevant State of Design, such as in the case of the UK's AD 003-03-97 for the BAe Jetstream 4100 model aircraft, which CASA has assessed and translated into an Australian AD/J4100/12. This AD is a legislative instrument, reflecting its significance in maintaining aviation safety and adhering to international standards.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to establish regulations for the Act, focusing on air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further mandates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are therefore legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by this legislation are primarily on CASA, as Australia’s national airworthiness authority. CASA must ensure that it assesses any airworthiness directives issued by the State of Design, which is the State responsible for the aircraft type's design, and determine if an Australian AD is necessary. The State of Registry, which is the State where the aircraft is registered, must develop or adopt requirements to ensure the aircraft's continuing airworthiness. If CASA deems an AD necessary, it must issue an Australian AD to mandate the requirements of the State of Design, ensuring compliance with international standards.
Failure to comply with the requirements outlined in an AD can lead to serious consequences. While the specific penalties for non-compliance are not detailed in the provided text, it is clear that such non-compliance could result in significant civil or criminal consequences, potentially including fines, sanctions, or other legal actions. The seriousness of these penalties reflects the critical importance of adhering to airworthiness directives to maintain safety standards in air navigation.
The legislation also ensures that certain ADs, particularly those issued in response to international obligations or directives from the State of Design, do not require public consultation. This is because these directives are often based on international agreements, such as the Convention on International Civil Aviation, and the Office of Best Practice Regulation has determined that they do not necessitate a Regulatory Impact Statement. The ADs are issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act. This streamlined process is designed to ensure that airworthiness directives are issued efficiently and effectively to maintain safety standards without unnecessary delays.
