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.
Transport Canada has issued AD CF-2004-28 affecting Pratt & Whitney Canada PW535A engines. Transport Canada is the State of Design for this engine type. CASA has assessed this AD and has issued Australian AD/PW500/3, which will become effective on 16 July 2010.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Continuing Airworthiness, in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988, enacted to govern the safety of air navigation in Australia, grants the Governor-General the authority to establish regulations that ensure aviation safety. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning certain types of aircraft or aeronautical products. The ADs are considered legislative instruments under the Legislative Instruments Act 2003. As part of Australia's obligations under the Convention on International Civil Aviation, CASA is required to assess and, if necessary, issue ADs to maintain the continuing airworthiness of aircraft registered in Australia. This involves evaluating directives issued by the State of Design and implementing corresponding Australian ADs. Given the international nature and technical requirements of such directives, there is no public consultation, and a Regulatory Impact Statement is not deemed necessary. The ADs are issued by CASA's Manager, Continuing Airworthiness, in the Airworthiness and Engineering Branch, in accordance with the Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, thereby ensuring the safety of air navigation in accordance with section 98 of the Civil Aviation Act 1988. These ADs, which are legislative instruments as per section 6 of the Legislative Instruments Act 2003, serve to implement the continuing airworthiness requirements mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design retains responsibility for the airworthiness of an aircraft type and must provide necessary information to ensure compliance, which is then assessed by CASA and, if appropriate, adopted as an Australian AD. This ensures the adherence to international standards and obligations under the Convention. Exemptions or exclusions from these regulations are not explicitly stated in the provided text, but they would typically be determined through the assessment process undertaken by CASA. The geographic reach of these regulations applies nationally within Australia, with CASA acting as the central authority for issuing and enforcing ADs in line with international obligations.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations to ensure the safety of air navigation, which includes the power to issue ADs (section 39.001 of the Civil Aviation Safety Regulations 1998). These directives are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. Subregulation 39.001(5) further classifies ADs as disallowable instruments. Importantly, the State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type, and must share necessary information with the States of Registry. The State of Registry, in turn, must ensure the ongoing airworthiness of individual aircraft, either by developing or adopting appropriate requirements.
Entities governed by the Civil Aviation Safety Regulations 1998 are obligated to comply with ADs issued by the Civil Aviation Safety Authority (CASA). This means that aircraft operators, manufacturers, and other relevant parties must adhere to the safety standards and maintenance requirements specified in the ADs. CASA, as the national airworthiness authority, assesses and issues these directives based on information from the State of Design. For example, in response to an airworthiness directive issued by Transport Canada for Pratt & Whitney Canada PW535A engines, CASA has issued its own AD/PW500/3, which incorporates the necessary requirements for the Australian context. The AD, which will become effective on 16 July 2010, is a result of Australia's commitments under the Convention on International Civil Aviation.
Failure to comply with an AD can have serious consequences. Civil penalties may be imposed for breaches, which can include fines and other sanctions. The severity of these penalties can vary, but they are intended to enforce compliance with safety regulations. Additionally, non-compliance with airworthiness directives can result in the grounding of aircraft, which poses significant safety risks and potential liability for operators. In the most severe cases, criminal charges may be pursued, especially if non-compliance leads to accidents or incidents that result in loss of life or significant damage.
In summary, the Civil Aviation Safety Regulations 1998 empower CASA to issue airworthiness directives that are essential for maintaining the safety and airworthiness of aircraft registered in Australia. These directives are based on international standards and must be complied with by all relevant parties. The consequences of non-compliance can include civil and criminal penalties, as well as operational restrictions that can have significant implications for aviation safety and public protection.
