CIVIL AVIATION ACT 1988
CIVIL AVIATION 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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 French DGAC has issued AD F-2002-331-071 R2 affecting AS355 /E, F, F1, F2 and N model rotorcraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AS355/67, Amendment 2, which will become effective on 17 February 2005. This AD cancels and replaces the previous issue.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, 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 framework for the regulation of civil aviation in Australia, addressing the need for a unified legal basis to govern air navigation, aircraft operations, and aviation safety. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation, thereby ensuring that civil aviation in Australia adheres to stringent safety standards. The Civil Aviation Act 1988, together with the Civil Aviation Regulations 1998, establishes the mechanisms through which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. These ADs are critical in implementing international safety standards as prescribed by the Convention on International Civil Aviation, particularly those concerning the responsibilities of the State of Design and the State of Registry in ensuring aircraft safety. By issuing ADs, CASA fulfills its duty under the Act to safeguard the safety of air navigation in Australia while complying with international obligations.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products to mandate safety requirements. The Act applies to entities involved in the operation of aircraft registered in Australia, including aircraft operators and manufacturers, and encompasses both domestic and international flights within Australia's jurisdiction. The scope extends to any aircraft type registered in Australia, regardless of the country of manufacture, ensuring compliance with international standards as outlined in Annex 8 of the Convention on International Civil Aviation. The ADs serve to maintain the continuing airworthiness of aircraft by implementing directives issued by the State of Design or in response to international safety concerns. Exemptions or thresholds for the application of ADs are not explicitly stated in the text, but they are likely to be determined by CASA on a case-by-case basis. The ADs are issued in accordance with the Act and can be subject to disallowance under the Acts Interpretation Act 1901, with the process for issuing such directives being streamlined to meet international obligations without the need for public consultation or Regulatory Impact Statements.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to establish regulations that serve the Act's objectives and ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. The ADs are an essential part of ensuring the continuing airworthiness of aircraft, which is a responsibility primarily borne by the State of Design as per Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions include the requirement for CASA to assess any ADs issued by the State of Design that affect aircraft on the Australian Register. If deemed appropriate, CASA must then issue an Australian AD to ensure compliance with the safety requirements specified by the State of Design. The State of Registry, in this case CASA, must also develop or adopt requirements to ensure the continuing airworthiness of the aircraft, aligning with Annex 8 of the Convention on International Civil Aviation. This systematic approach ensures that Australian aircraft meet international safety standards, thereby maintaining a high level of safety in air navigation.
The issuance of the AD/AS355/67, Amendment 2, in response to the French DGAC’s AD F-2002-331-071 R2, illustrates the practical application of these provisions. France, as the State of Design, issued an AD affecting AS355 models, which CASA subsequently assessed and responded to with an Australian AD. This AD, effective from 17 February 2005, replaces the previous Australian AD, ensuring that all relevant safety measures are uniformly applied across the affected aircraft.
Breaches of these regulations or failure to comply with the requirements outlined in an AD can lead to serious consequences. Non-compliance with ADs can result in severe penalties, including fines and imprisonment, reflecting the critical importance of adhering to these safety directives. The maximum penalties are determined by the severity of the breach and the impact on air navigation safety. Civil and criminal actions may be taken against individuals or entities that fail to comply, underscoring the importance of these regulations in maintaining the integrity and safety of air navigation.
