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 2007-03-03 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/B737/310, which will become effective on 26 October 2007.
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, addressing the need for regulations that ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations in the interests of air navigation safety, a necessary step to align Australia's aviation practices with international standards and to safeguard the public. The Civil Aviation Safety Regulations 1998, under section 39.001, further delineate the authority of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, thereby ensuring that aircraft on the Australian Register maintain their airworthiness in accordance with international conventions, particularly Annex 8 to the Convention on International Civil Aviation. This legislative framework facilitates the efficient dissemination of safety-critical information, enabling CASA to mandate requirements derived from ADs issued by States of Design, such as the United States in the case of Boeing B737 model aircraft. The ADs are issued without public consultation, as they respond to international obligations and pre-existing directives from the State of Design.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific kinds of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The ADs serve to ensure the continuing airworthiness of aircraft registered in Australia, aligning with the requirements set out in Annex 8 of the Convention on International Civil Aviation. The State of Design, such as the United States for Boeing B737 models, holds primary responsibility for issuing ADs, and CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue corresponding Australian ADs to maintain safety standards. This process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs are made by authorised CASA officials in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations for the Act's purposes, specifically to ensure air navigation safety. Under this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as a formal instruction to ensure the continuing airworthiness of aircraft, and they are a legislative instrument as defined by section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations require CASA to assess any ADs issued by the State of Design, particularly those that may affect aircraft registered in Australia. For example, when the US Federal Aviation Administration (FAA) issues an AD such as AD 2007-03-03 for Boeing B737 model aircraft, CASA must review and assess this directive. If deemed appropriate, CASA issues a corresponding Australian AD, like AD/B737/310, which mandates compliance with the State of Design's requirements. The State of Registry, in this case, Australia, is then responsible for ensuring the aircraft comply with the AD's stipulations.
Given the international nature of airworthiness directives, and their necessity to meet the standards set forth in Annex 8 to the Convention on International Civil Aviation, CASA is mandated to act on ADs issued by the State of Design without requiring further consultation with the Australian public. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. CASA issues these directives on behalf of the Australian government, adhering to the provisions of section 84A(2) of the Civil Aviation Act 1988.
Any failure to comply with an airworthiness directive can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance can lead to enforcement actions, including fines, suspension, or revocation of an aircraft's certificate of airworthiness. The maximum penalties for breaches can be substantial, reflecting the critical importance of adhering to airworthiness requirements. Criminal penalties may also apply, depending on the nature and severity of the non-compliance. These measures underscore the importance of ensuring that all aircraft meet the necessary safety standards to protect the public and maintain the integrity of the aviation system.
