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 Kingdom Civil Aviation Authority (UKCAA) has issued AD
G-2009-0001 affecting DHC-1 model aircraft. The United Kingdom is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-1/39, which will become effective on 9 April 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting 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 a comprehensive legislative framework governing civil aviation in Australia, addressing issues related to the safety, efficiency, and economic viability of the aviation industry. This Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. One such regulation, under section 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified aircraft or aeronautical products. These ADs serve as legislative instruments, playing a crucial role in maintaining the continuing airworthiness of aircraft in line with international standards. This regulatory approach is essential for aligning Australia's aviation safety practices with the obligations under the Convention on International Civil Aviation, ensuring uniformity and safety across the industry.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance, and are integral to maintaining the continuing airworthiness of aircraft as per Annex 8 of the Convention on International Civil Aviation. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to ensure continuing airworthiness. In Australia, CASA, as the national airworthiness authority, assesses this information and, if necessary, issues corresponding ADs to enforce the requirements. For example, in response to the UK Civil Aviation Authority’s AD G-2009-0001 concerning DHC-1 model aircraft, CASA issued Australian AD/DHC-1/39, effective from 9 April 2009. Given the international nature of these directives and their alignment with ICAO standards, public consultation and a Regulatory Impact Statement are not required. This AD was issued by the Acting Manager, Airframe and Structures in the Airworthiness Engineering Group, CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, in section 98, empowers the Governor-General to create regulations that serve the interests of air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) of these regulations stipulates that an AD is a disallowable instrument, meaning it is subject to parliamentary scrutiny, as per section 46A of the Acts Interpretation Act 1901. Accordingly, an AD is classified as a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties and entities include the requirement for CASA to review and potentially issue Australian ADs when a State of Design issues an AD against an aircraft type registered in Australia. The State of Design, such as the United Kingdom Civil Aviation Authority (UKCAA) for the DHC-1 model aircraft, must provide necessary information to ensure the continuing airworthiness of the aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case Australia, must also develop or adopt requirements to ensure the continuing airworthiness of the aircraft and act on ADs issued by the State of Design.
Failure to comply with an airworthiness directive can lead to significant consequences. Under the Civil Aviation Act 1988, aircraft found to be non-compliant with an AD can be grounded, and operators may face fines or other penalties. The severity of these penalties depends on the nature and extent of the non-compliance, but they are designed to ensure that all aircraft maintain the required safety standards. The regulations also provide for the enforcement of these directives through CASA, which has the authority to take action against non-compliant aircraft and operators.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance and enforcement of airworthiness directives to ensure the safety of aircraft in Australia. CASA is responsible for assessing and implementing these directives, which are crucial for maintaining the continuing airworthiness of aircraft as required by international conventions. Non-compliance with these directives can result in significant penalties, underscoring the importance of adhering to the regulations.
