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.
CASA has issued AD/GA8/5 Amendment 2 to correct an unsafe situation on GA8 aircraft. The AD has been amended following a minor change to the inspection procedure to account for a new hardware configuration in later series aircraft. As Australia is the State of Design for the GA8, CASA is required to develop, and to transmit to other States of Registry, an AD to correct the problem. This AD cancels and replaces the previous issue.
CASA has not consulted with the Australian industry and public. This is because there is no increased cost or time in completing the modified inspection.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the acting Manager Airframe and Structures, 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 regulate civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. This legislation grants the Governor-General the authority to make regulations for the Act's purposes, particularly in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. CASA's role as Australia's national airworthiness authority involves assessing information from the State of Design and issuing necessary ADs to ensure the continuing airworthiness of aircraft registered in Australia. Recently, CASA issued AD/GA8/5 Amendment 2 to address a safety issue on GA8 aircraft, reflecting a minor change to the inspection procedure for a new hardware configuration. The AD replaces the previous version, and CASA has determined that consultation with the industry and public was unnecessary due to the lack of increased costs or time required for the modified inspection. The Office of Regulatory Review has confirmed that ADs do not necessitate a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, as they are disallowable under section 46A of the Acts Interpretation Act 1901 and subject to the Legislative Instruments Act 2003. In particular, CASA has issued AD/GA8/5 Amendment 2 to address an unsafe condition on GA8 aircraft, reflecting a minor change in the inspection procedure to accommodate a new hardware configuration in later series aircraft. As the State of Design for the GA8 aircraft, CASA is obligated to develop and transmit this AD to other States of Registry to ensure the continuing airworthiness of the aircraft type. This AD cancels and replaces the previous issue, and CASA has determined that consultation with the Australian industry and public is unnecessary as there are no additional costs or time implications associated with the modified inspection. Furthermore, the Office of Regulatory Review has concluded that ADs do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interest of safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in section 6 of the Legislative Instruments Act 2003. According to Annex 8 to the Convention on International Civil Aviation, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure this airworthiness to the States of Registry, which includes Australia.
Under these regulations, CASA, as Australia’s national airworthiness authority, is mandated to assess information provided by the State of Design and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This process was followed in the case of AD/GA8/5 Amendment 2, which was issued to address an unsafe condition on GA8 aircraft. This amendment was made to correct an inspection procedure to account for a new hardware configuration found in later series aircraft. Given that Australia is the State of Design for the GA8, CASA is required to develop and transmit this AD to other States of Registry. This particular AD replaces the previous version, ensuring that the latest safety measures are implemented.
The obligations imposed on parties by these regulations are significant. CASA, as the issuing authority, must ensure that any safety concerns identified are promptly addressed through the issuance of appropriate ADs. Aircraft operators and other stakeholders are required to comply with these directives to maintain the airworthiness of their aircraft. Failure to adhere to the provisions of an AD can result in serious safety implications and may lead to penalties under the Civil Aviation Act 1988. Additionally, CASA must provide clear and concise guidance on the implementation of these directives to ensure compliance across the aviation industry.
Breach of the requirements outlined in an airworthiness directive can lead to various civil and criminal consequences. Under the Civil Aviation Act 1988, non-compliance can result in fines and potential prosecution. The maximum penalties for offences can vary, but they may include substantial financial penalties and, in severe cases, imprisonment. The enforcement of these penalties is critical to maintaining high safety standards in the aviation sector, ensuring that all parties are held accountable for their role in ensuring the continuing airworthiness of aircraft.
