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 raised AD/GA8/5, to correct an unsafe situation on Gippsland Aeronautics GA8 model aircraft. GA8 operators have experienced a number of problems relating to the attachment of the horizontal stabiliser. This directive requires a number of inspections and improvements aimed at overcoming these problems, and is based on service documentation provided by Gippsland Aeronautics. 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 directive will become effective on 15 February 2007.
CASA has not consulted widely with the Australian public. However, the directive has been raised as a result of consultation with, and with the support of, the aircraft manufacturer. Because of the potential consequences of a failure, urgent action is required, and this would be significantly delayed by widespread public consultation.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting General Manager, 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 regulate civil aviation in Australia, providing a framework to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which in turn allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that mandate safety requirements to address unsafe situations and ensure the continuing airworthiness of aircraft. For instance, AD/GA8/5 was issued to address safety concerns with the Gippsland Aeronautics GA8 model aircraft, requiring specific inspections and improvements based on manufacturer documentation. While the Act requires CASA to develop ADs to correct unsafe situations, the process does not necessitate extensive public consultation due to the urgency and potential consequences of non-compliance. The ADs are developed in consultation with relevant stakeholders, including aircraft manufacturers, to ensure effective and timely implementation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation in Australia. These regulations empower CASA to mandate specific requirements for kinds of aircraft or aeronautical products, ensuring compliance with international standards set by the Convention on International Civil Aviation, particularly through Annex 8, which delineates the responsibilities of States of Design and States of Registry in maintaining the airworthiness of aircraft. The ADs are legislative instruments, subject to disallowance and oversight as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. In the case of Gippsland Aeronautics GA8 model aircraft, CASA issued AD/GA8/5 to address specific safety issues related to the attachment of the horizontal stabiliser, which required immediate attention and corrective measures. As Australia is the State of Design for the GA8, CASA is mandated to develop and disseminate this directive to other States of Registry, ensuring a coordinated international response to safety concerns. The directive became effective on 15 February 2007, reflecting the urgency of the safety issues identified. While CASA did not undertake extensive public consultation due to the critical nature of the safety issues, the directive was developed in consultation with the aircraft manufacturer, highlighting the collaborative approach in addressing airworthiness concerns.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, particularly in conjunction with the Civil Aviation Safety Regulations 1998, establish a framework for ensuring the safety of air navigation (s 98). Under these provisions, the Governor-General has the authority to make regulations, and the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (reg 39.001). These ADs are legislative instruments that must be assessed and, if necessary, adopted by the State of Registry to ensure the continuing airworthiness of aircraft (reg 39.001(5)). In this context, CASA is responsible for issuing Australian ADs to address safety concerns identified by the State of Design.
The Civil Aviation Safety Regulations 1998 impose several obligations on parties and entities governed by the Act. For instance, the State of Design must provide any necessary information to ensure the continuing airworthiness of an aircraft type (Annex 8). CASA, as the national airworthiness authority, must then assess this information and issue an Australian AD if appropriate. In the case of the Gippsland Aeronautics GA8 model aircraft, CASA issued AD/GA8/5 to address problems with the attachment of the horizontal stabiliser, necessitating inspections and improvements (Annex 8). Operators of the GA8 must comply with these directives to maintain the airworthiness of their aircraft.
Failure to comply with ADs can result in serious consequences. While CASA has not widely consulted the public on this specific AD due to the urgency of the situation, non-compliance with an AD can lead to severe penalties. Under the Legislative Instruments Act 2003, ADs are legislative instruments, and violations can incur both civil and criminal penalties, depending on the severity of the breach. The maximum penalties for non-compliance with airworthiness directives are not explicitly stated in the provided text but can include fines and imprisonment, reflecting the critical importance of adhering to these safety measures.
