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 2007-23-10 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/311, which will become effective on 17 January 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 civil aviation in Australia, ensuring safety, efficiency, and order in the sector. One of the key provisions of this Act is the authority it grants to the Governor-General to make regulations in the interest of air navigation safety, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are critical for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further detail the process for issuing such directives. Given the international nature of aviation, these directives often respond to similar directives issued by other countries, such as the US Federal Aviation Administration (FAA), and are issued without public consultation as they are integral to fulfilling international obligations. The ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the purposes of the Act, and in this case, regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and as such, they fall under the legislative instruments as per the Legislative Instruments Act 2003. The ADs are issued in response to the requirements outlined in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design, in this case, the United States for the Boeing B737 model aircraft, provides necessary information to ensure continuing airworthiness. CASA, as Australia's national airworthiness authority, is obligated to assess this information and, if necessary, issue corresponding Australian ADs to mandate the requirements set by the State of Design. This process ensures that the continuing airworthiness of aircraft registered in Australia aligns with international safety standards.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act allows the Governor-General to make regulations for the purposes of the Act, and regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments and are considered disallowable under section 46A of the Acts Interpretation Act 1901.
The obligations placed on parties by these provisions include the responsibility of the State of Design to ensure the continuing airworthiness of aircraft types and to provide necessary information to States of Registry. In turn, States of Registry, such as Australia through CASA, must develop or adopt requirements to maintain the airworthiness of aircraft. When the State of Design, like the United States in this case, issues an AD, CASA must assess the information and, if deemed necessary, issue a corresponding Australian AD. For example, in response to the US FAA's AD 2007-23-10 affecting Boeing B737 model aircraft, CASA issued AD/B737/311, effective from 17 January 2008. This process is conducted without public consultation and does not require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Breaching the requirements set out in these ADs can lead to significant consequences. While specific offences and penalties are not detailed in the provided text, it is implicit that non-compliance with airworthiness directives could result in serious safety issues, potentially leading to criminal charges or civil liability. The consequences of such breaches could include fines, imprisonment, or other penalties as prescribed by the applicable legislation. The exact nature and extent of these penalties would depend on the specific circumstances and the relevant laws governing aviation safety.
