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 US FAA has issued AD 2007-25-18 affecting Boeing B747-400 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/371, which will become effective on 13 March 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 comprehensive legal framework for the regulation of civil aviation in Australia. It was introduced to address the need for a unified and systematic approach to managing aviation safety, operations, and related activities within the country. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, and it establishes the Civil Aviation Safety Authority (CASA) as the national airworthiness authority responsible for ensuring the safety and airworthiness of aircraft within Australia. The Act's primary policy objective is to enhance the safety and efficiency of civil aviation, aligning with international standards and obligations under the Convention on International Civil Aviation.
The Civil Aviation Safety Regulations 1998, made under the authority of the Civil Aviation Act 1988, further detail the regulatory requirements for airworthiness, including the process for issuing airworthiness directives (ADs). An AD is a legislative instrument issued by CASA in response to safety concerns identified by the State of Design or in compliance with international agreements. These directives mandate specific safety measures for particular types of aircraft or aeronautical products. The issuing of these directives is a critical function for CASA, ensuring that Australian aircraft meet necessary safety standards and comply with international obligations. The legislative framework thus facilitates the effective management of aircraft airworthiness and safety, reflecting Australia’s commitment to international civil aviation standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively govern the issuance of airworthiness directives (ADs) in Australia. Specifically, under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations that pertain to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs serve as a mechanism for ensuring the continuing airworthiness of aircraft, a responsibility that ultimately lies with the State of Registry, which in Australia's case is CASA. This legislative framework mandates that CASA must act in accordance with international obligations under the Convention on International Civil Aviation, particularly when the State of Design issues an AD affecting aircraft registered in Australia. Exemptions from public consultation and Regulatory Impact Statements are permissible for such ADs, as they are issued in response to international directives and obligations.
Key Provisions
Under the Civil Aviation Act 1988, the Governor-General is empowered to make regulations, as stated in section 98, for the purpose of ensuring the safety of air navigation. This legislative framework is critical for maintaining high safety standards in the aviation sector. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are a formal legislative instrument as per subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties such as CASA and the State of Registry are substantial. The State of Design, which in this case is the United States for Boeing B747-400 model aircraft, has the responsibility to ensure the continuing airworthiness of the aircraft type and to provide necessary information to other States of Registry. The State of Registry, here being Australia, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its territory. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, is required to assess this information and, if appropriate, issue a corresponding Australian AD.
Failure to comply with airworthiness directives can lead to serious consequences. Although the specific penalties are not detailed in the provided text, non-compliance generally attracts severe regulatory action. This could include civil penalties or criminal charges depending on the severity of the breach. Such actions are intended to ensure that all parties maintain the high safety standards necessary for the aviation industry. The legislative process for issuing ADs, such as AD/B747/371, is designed to ensure that all measures are in place to protect public safety while adhering to international standards set forth in the Convention on International Civil Aviation.
