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-98-22 affecting Bell 230 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 222/40, which will become effective on 30 August 2007.
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 Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish and maintain a regulatory framework for civil aviation safety in Australia. It provides the legislative basis for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. Under this Act, the Governor-General can make regulations in the interest of safety, and CASA has the authority to issue ADs for types of aircraft or aeronautical products as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. This authority is exercised to ensure compliance with international standards and to mandate safety requirements for aircraft registered in Australia, particularly in response to directives from the State of Design as per Annex 8 of the Convention on International Civil Aviation. The policy objective is to maintain and enhance the safety standards of civil aviation in Australia in alignment with international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are essential tools for ensuring the continuing airworthiness of aircraft and are issued by CASA in response to international obligations and requirements set forth under the Convention on International Civil Aviation. ADs are mandated by the State of Design of an aircraft type, which must provide necessary information to the State of Registry to maintain airworthiness. In Australia, CASA assumes the responsibility of assessing these directives and, if deemed necessary, issues corresponding Australian ADs to enforce the requirements. For instance, in response to an AD issued by Transport Canada regarding Bell 230 model helicopters, CASA has issued Australian AD/BELL 222/40, reflecting Australia's commitment to international civil aviation standards. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and oversight by the Legislative Instruments Act 2003. While these directives are integral to ensuring safety and compliance, they do not require public consultation or a Regulatory Impact Statement, as they are issued in adherence to international obligations and specific technical requirements.
Key Provisions
The Civil Aviation Act 1988 provides the framework for the regulation of civil aviation in Australia, and under section 98, it allows the Governor-General to make regulations necessary for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are a form of legislative instrument under the Legislative Instruments Act 2003, as they are disallowable instruments under the Acts Interpretation Act 1901. The State of Design, which is the country where the aircraft type is designed, is primarily responsible for ensuring the continuing airworthiness of the aircraft type, including providing necessary information to other States of Registry as outlined in Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, the State of Registry, which is the country where the individual aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When a State of Design, such as Canada, issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, is obligated to assess this information. If appropriate, CASA must then issue an Australian AD to enforce the requirements specified by the State of Design. This process ensures that Australian-registered aircraft meet the international safety standards set by their respective States of Design.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA include assessing the airworthiness directives issued by the States of Design and, where necessary, issuing corresponding Australian ADs. CASA must also ensure that the ADs are compliant with the international standards set forth by ICAO. This involves a thorough evaluation of the safety concerns and necessary corrective actions outlined in the foreign ADs. Additionally, CASA must maintain records of all ADs issued and ensure that they are effectively communicated to the relevant stakeholders, including aircraft operators and owners.
Failure to comply with an airworthiness directive may result in severe consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered an offence, leading to potential civil or criminal penalties. The specific penalties can vary but may include fines or imprisonment, depending on the severity of the breach and the impact on aviation safety. The exact penalties are determined by the courts and can be significant, reflecting the critical importance of adhering to airworthiness directives to maintain the safety of air navigation.
