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 U.S. FAA issued AD 2007-26-12 and an Alternate Method of Compliance (AMOC), affecting Robinson Helicopter Company R44 aircraft, in 2007. The US is the State of Design for the R44 type. As a result of a request from industry, CASA has amended the equivalent Australian AD, AD/R44/22 Amendment 1, to correct a typographical error. The amended AD, AD/R44/22 Amendment 2, will become effective on 3 March 2008. This AD cancels and replaces the previous issue.
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, 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, enacted by the Parliament of Australia, was introduced to regulate civil aviation within Australia, ensuring safety and efficiency in air navigation. One of the critical mechanisms established by this Act is the ability for the Governor-General to issue regulations aimed at enhancing the safety of air navigation, which includes the authority to mandate airworthiness directives through regulation 39.001 of the Civil Aviation Safety Regulations 1998. This legislative framework is designed to align with international standards as set forth by the International Civil Aviation Organization (ICAO) and to meet Australia's obligations under the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) exercises its powers under the Act to issue airworthiness directives, ensuring that aircraft and aeronautical products meet the necessary safety standards. These directives, which are legislative instruments, are issued to address specific safety concerns and ensure the continuing airworthiness of aircraft registered in Australia, thereby protecting the public and maintaining the integrity of the national aviation system.
Scope and Application
The Civil Aviation Act 1988 and associated Civil Aviation Safety Regulations 1998 provide a framework for the regulation of airworthiness directives (ADs) in Australia, ensuring the safety of aircraft within Australia's jurisdiction. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, following the requirements outlined in regulation 39.001 and subregulation 39.001(5). This legislative instrument is critical for maintaining the continuing airworthiness of aircraft registered in Australia, aligning with the responsibilities of the State of Registry and the obligations under Annex 8 to the Convention on International Civil Aviation. ADs are issued to address safety concerns or discrepancies identified in aircraft types, ensuring compliance with international standards and regulations. The application of these ADs is geographically limited to Australia, with CASA acting as the national authority to enforce these directives. Notably, ADs are not subject to public consultation or a Regulatory Impact Statement, given their nature as technical safety measures rather than broader policy changes. This streamlined process ensures timely responses to safety issues without unnecessary delays.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, as applied to the issuing of airworthiness directives (ADs), are section 98 which empowers the Governor-General to make regulations for the purposes of the Act, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. This authority is exercised in the interests of the safety of air navigation and in accordance with the provisions of Annex 8 to the Convention on International Civil Aviation. An AD, once issued, is a legislative instrument that is disallowable under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Act and the Regulations on CASA include assessing the information provided by the State of Design, which has overall responsibility for the continuing airworthiness of an aircraft type, and issuing an Australian AD if appropriate. The State of Registry, which in Australia is CASA, is responsible for the continuing airworthiness of individual aircraft and must develop or adopt requirements to ensure compliance. This process ensures that Australian registered aircraft meet international standards of safety and airworthiness.
The Act and the Regulations impose specific obligations on entities such as aircraft manufacturers and operators. For example, manufacturers must provide any necessary information to ensure the continuing airworthiness of their aircraft types, while operators must comply with the ADs issued by CASA. Failure to comply with these obligations can result in severe consequences, including the grounding of aircraft and potential legal penalties.
Breaching the provisions of the Act and the Regulations can lead to both civil and criminal consequences. Under the Civil Aviation Act 1988, an offence is committed if a person contravenes any provision of the Act or any regulation made under it. The maximum penalties for such offences can include substantial fines and imprisonment. For instance, under section 113 of the Act, an individual can face a fine of up to $162,000 and imprisonment for up to two years for contravening certain safety regulations. Additionally, CASA has the authority to take enforcement actions, such as issuing compliance orders or revoking airworthiness certificates, which can further impact the operations of non-compliant entities.
