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 United States FAA has issued AD 2008-26-10 affecting Cessna 180 type aeroplanes. The United States is the State of Design for this aeroplane type. CASA has assessed this AD and has issued Australian AD/CESSNA 180/94, which will become effective on 16 January 2009.
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, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was established to regulate civil aviation in Australia, with a particular focus on ensuring the safety of air navigation. One of the key mechanisms through which this is achieved is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments, which are subject to disallowance and the Legislative Instruments Act 2003. The Civil Aviation (Safety Authority) Act 1990 empowers the Civil Aviation Safety Authority (CASA) to issue ADs that mandate compliance with airworthiness requirements, ensuring that aircraft remain safe and airworthy. This legislative framework responds to Australia’s obligations under the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of the State of Design and the State of Registry concerning the continuing airworthiness of aircraft types.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia, ensuring that the safety of air navigation is upheld. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These directives, which are considered legislative instruments under the Legislative Instruments Act 2003, are issued to mandate requirements for the continuing airworthiness of aircraft, following assessments based on international standards such as those set out in Annex 8 to the Convention on International Civil Aviation. The issuance of an AD by CASA, Australia's national airworthiness authority, typically occurs in response to an AD issued by the aircraft's State of Design, as is the case with AD/CESSNA 180/94, which was issued in response to the United States Federal Aviation Administration’s AD 2008-26-10. This process underscores the collaborative nature of international civil aviation safety, where Australia, as the State of Registry, has a duty to implement and enforce ADs to maintain the safety standards of aircraft registered within its jurisdiction.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act allows the Governor-General to make regulations for air safety, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. This regulatory power is significant, as ADs are critical tools for maintaining the continuing airworthiness of aircraft, and they are considered legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations on parties such as CASA, aircraft manufacturers, and operators are extensive. CASA, as the national airworthiness authority, must rigorously assess any ADs issued by the State of Design and decide if they need to be adopted and enforced within Australia. This includes evaluating the safety implications of the AD and determining if modifications are necessary to meet Australian standards. Operators of affected aircraft must comply with the ADs by following the prescribed maintenance and operational procedures to ensure their aircraft remain airworthy. These obligations are designed to uphold the highest safety standards in line with international conventions, particularly Annex 8 of the Convention on International Civil Aviation.
Non-compliance with ADs can lead to severe consequences, including both civil and criminal penalties. Under the Civil Aviation Act 1988, operators who fail to comply with an AD can be fined significant amounts. For instance, the maximum penalty for each day of non-compliance can be substantial, reflecting the serious nature of maintaining airworthiness. Additionally, CASA has the authority to take enforcement actions such as grounding non-compliant aircraft, which can have severe operational and financial repercussions for the operators. These penalties underscore the critical importance of adhering to ADs to ensure the safety and integrity of the aviation system.
