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 Civil Aviation Safety Authority or its predecessors issued AD/S-76/2 affecting Sikorsky S-76 series helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/S-76/2. The cancellation will become effective on
2 July 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, with a focus on safety and the efficient use of airspace. One of the key provisions of this Act is the authority for the Governor-General to make regulations that promote the safety of air navigation, which includes the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further detail the circumstances under which CASA can issue such directives to ensure the continuing airworthiness of aircraft and aeronautical products, which are essential for maintaining safety standards in compliance with international obligations under the Convention on International Civil Aviation. This legislative framework ensures that CASA, as Australia's national airworthiness authority, can effectively manage and respond to safety issues by issuing, amending, or cancelling airworthiness directives as necessary.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of aircraft within Australia. These regulations empower CASA to issue ADs for specific kinds of aircraft or aeronautical products, establishing critical safety mandates to maintain the continuing airworthiness of aircraft registered in Australia. The ADs are considered legislative instruments under the Acts Interpretation Act 1901, and they reflect Australia’s commitment to international standards as set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the country where the aircraft is designed, holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry, in this case, Australia, must enforce these safety mandates to ensure compliance. In specific instances, CASA may cancel an existing AD if the unsafe condition it was intended to address no longer exists, as seen with the cancellation of AD/S-76/2 for the Sikorsky S-76 series helicopters on 2 July 2009. This cancellation was made in accordance with Australia’s obligations under international civil aviation conventions, and no public consultation or Regulatory Impact Statement was required.
Key Provisions
The Civil Aviation Act 1988 (the Act) empowers the Governor-General to make regulations for the safety of air navigation, as per section 98. The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments under subregulation 39.001(5) and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. This regulatory framework is designed to ensure the ongoing airworthiness of aircraft, aligning with international standards under Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry.
Under this Act and the accompanying regulations, CASA, as Australia’s national airworthiness authority, is mandated to assess any airworthiness directives issued by the State of Design. If an AD is issued by a foreign State of Design, CASA must evaluate the information provided and determine if it is appropriate to issue an Australian AD. This ensures that Australian-registered aircraft comply with international safety standards. For instance, CASA assessed and subsequently cancelled Australian AD/S-76/2 for Sikorsky S-76 series helicopters due to the resolution of the unsafe condition identified by the AD. This cancellation was made in accordance with Australia's obligations under the Convention on International Civil Aviation, and it became effective on 2 July 2009.
The obligations imposed on parties governed by the Act include compliance with any airworthiness directives issued by CASA. Aircraft operators and other relevant entities must adhere to the requirements specified in these directives to maintain the safety and airworthiness of their aircraft. Failure to comply with these directives can result in severe consequences, including civil and criminal penalties. While the specific consequences depend on the nature and severity of the breach, the regulations under the Act are designed to enforce strict compliance to prevent any compromise in aviation safety.
In terms of penalties, breaches of airworthiness directives can lead to substantial fines and, in severe cases, criminal charges. For example, under the Act, an individual or entity found in violation of an airworthiness directive may face a fine of up to $330,000 for a corporation and $66,000 for an individual, as well as imprisonment for up to five years. These penalties underscore the importance of adhering to the airworthiness directives and the serious consequences of non-compliance.
