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 US FAA has issued AD 2008-05-06 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/316, which will become effective on 8 April 2008.
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 Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, serves to ensure the safety and efficiency of civil aviation within Australia. This Act empowers the Governor-General to establish regulations aimed at maintaining the safety of air navigation, ensuring that aviation operations adhere to the highest safety standards. In line with this mandate, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby enforcing the necessary compliance measures. These directives are critical in maintaining the continuing airworthiness of aircraft, ensuring they meet safety standards set forth by international conventions, such as Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is tasked with assessing and implementing ADs issued by the State of Design, thereby fulfilling Australia’s obligations under international agreements and ensuring the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, particularly the Civil Aviation Safety Regulations 1998, provide a framework for ensuring the safety of air navigation in Australia. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specified kinds of aircraft or aeronautical products to ensure that they remain airworthy. These directives are legislative instruments and must comply with the requirements set out in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs serve as the primary mechanism for communicating continuing airworthiness information, particularly when issued by the State of Design or in response to international obligations under the Convention on International Civil Aviation. The State of Registry, in this case CASA, has a responsibility to ensure the continuing airworthiness of aircraft registered in Australia, which includes assessing and, where necessary, implementing ADs issued by other States of Design. The process of issuing an Australian AD follows the assessment of an AD from the relevant State of Design, ensuring that Australian aviation safety standards are aligned with international obligations and practices. Notably, these ADs are not subject to public consultation or regulatory impact statements, reflecting their technical and safety-focused nature.
Key Provisions
The Civil Aviation Act 1988 provides the legal framework for ensuring the safety of air navigation within Australia, with key operative sections including section 98 which empowers the Governor-General to make regulations for this purpose. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft and are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations on parties and entities include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type, as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to the State of Registry, which must then develop or adopt requirements to maintain the airworthiness of individual aircraft registered within its jurisdiction. In the case of Australia, CASA is responsible for assessing ADs issued by the State of Design and, if appropriate, issuing corresponding Australian ADs to mandate the necessary requirements.
Breaches of the requirements set forth in airworthiness directives can lead to serious consequences. While specific offences and penalties are not detailed in the provided text, the nature of these directives and their critical role in aviation safety suggest that non-compliance could result in both civil and criminal liabilities. Operators who fail to adhere to ADs may face enforcement actions from CASA, potentially including fines, suspension of airworthiness certificates, and other regulatory penalties. The exact penalties would depend on the severity of the breach and any relevant aviation regulations or laws.
