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/AA-1/15 affecting Gulfstream AA-1 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-1/15. The cancellation will become effective on 4 June 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, 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 was enacted to provide for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. Under the Act, the Governor-General has the authority to make regulations for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 detailing various requirements, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments made under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue Australian ADs to ensure compliance with international standards. In the case of AD/AA-1/15 affecting Gulfstream AA-1 model aircraft, CASA has cancelled the directive as the unsafe condition no longer exists, without requiring public consultation or a Regulatory Impact Statement, in line with Australia’s obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, through the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. These ADs are legislative instruments and serve as a critical mechanism for ensuring the ongoing airworthiness of aircraft registered in Australia, aligning with international standards set by the International Civil Aviation Organization (ICAO). The authority to issue these directives is exercised by CASA, which acts as the national airworthiness authority for Australia, assessing and responding to ADs issued by the State of Design, particularly when these pertain to aircraft on the Australian Register. The process ensures compliance with Annex 8 of the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry in maintaining the airworthiness of aircraft. The ADs are integral to the safety of air navigation, and their issuance or cancellation is subject to the legislative framework and international obligations, as demonstrated in the case of AD/AA-1/15 affecting Gulfstream AA-1 model aircraft, which was cancelled by CASA following an assessment that the unsafe condition no longer existed.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Regulations permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are legislative instruments that must be assessed and approved according to the requirements of the Legislative Instruments Act 2003.
Under the Convention on International Civil Aviation, the State of Design bears overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the individual aircraft’s airworthiness. CASA, as Australia’s national airworthiness authority, is tasked with assessing the information provided by the State of Design and issuing Australian ADs when necessary. This process ensures that Australian aircraft meet the required safety standards set by international and domestic regulations.
In a specific instance, CASA issued AD/AA-1/15 concerning Gulfstream AA-1 model aircraft. Following an assessment, CASA has determined that the unsafe condition addressed by AD/AA-1/15 no longer exists, and therefore has cancelled this directive. The cancellation of AD/AA-1/15 will take effect on 4 June 2009, and no replacement AD is required. The decision to cancel this directive was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, and no consultation with the Australian public was conducted on this matter. Furthermore, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
The Civil Aviation Act and the Civil Aviation Safety Regulations impose several obligations on CASA and other entities involved in ensuring the safety and airworthiness of aircraft. CASA must assess the ADs issued by the State of Design and decide whether to issue corresponding Australian ADs. Failure to comply with these obligations may result in breaches of safety regulations, which could lead to civil or criminal penalties. The maximum penalties for non-compliance with the Civil Aviation Act and the Regulations can include fines and imprisonment, depending on the severity of the breach and the specific provisions of the Act or Regulations that have been violated.
