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 French DGAC has issued AD F-2004-052 R1 affecting Eurocopter SA365 model helicopters. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DAUPHIN/70, Amendment 1, which will become effective on 24 November 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 Manager, Airframes in the 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 provide a comprehensive regulatory framework for civil aviation in Australia, addressing issues related to the safety and efficiency of air navigation. This legislation empowers the Governor-General to create regulations in the interest of air navigation safety, as exemplified by the Civil Aviation Safety Regulations 1998. These regulations permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments that mandate compliance with specific safety standards for aircraft and aeronautical products. The objective of these ADs is to ensure the continuing airworthiness of aircraft by enforcing requirements set by the State of Design and Registry, aligning with international standards set forth in the Convention on International Civil Aviation. CASA's role includes assessing foreign ADs and issuing corresponding Australian ADs when necessary, thereby fulfilling Australia's international obligations and enhancing domestic aviation safety.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to specific types of aircraft and aeronautical products. These directives are issued to ensure the continuing airworthiness of aircraft registered in Australia, thereby enhancing the safety of air navigation. The ADs, as disallowable instruments under the Acts Interpretation Act 1901, are legislative instruments that CASA can mandate based on assessments of directives issued by the State of Design, such as France for the Eurocopter SA365 model helicopters. The ADs are implemented in accordance with Annex 8 to the Convention on International Civil Aviation, which assigns responsibilities to the State of Design and the State of Registry. Notably, while the issuance of ADs is grounded in international obligations, they are subject to CASA's evaluation and do not require public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review. The ADs extend to mandating specific requirements for aircraft registered in Australia, thereby ensuring compliance with international standards of airworthiness.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, includes provisions that allow for the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. An AD is a legislative instrument that is issued by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft types, and it is a mechanism by which CASA mandates requirements for specific aircraft or aeronautical products. This is in line with the obligations of the State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds responsibility for the continuing airworthiness of an aircraft type.
Under these provisions, the obligations imposed on CASA and other entities include assessing the necessity and appropriateness of issuing an AD in response to a State of Design AD, and ensuring that the AD mandates the required safety measures. For example, when the French Direction Générale de l'Aviation Civile (DGAC) issued AD F-2004-052 R1 for Eurocopter SA365 model helicopters, CASA assessed this directive and issued Australian AD/DAUPHIN/70, Amendment 1. This process ensures that Australian-registered aircraft meet international safety standards and comply with the directives issued by the aircraft's State of Design.
Failure to comply with an AD can result in serious consequences. While the specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with ADs can have both civil and criminal implications. Typically, the Civil Aviation Act 1988 and associated regulations may impose penalties for non-compliance, which could include fines and, in more serious cases, imprisonment. The exact penalties would depend on the nature and severity of the non-compliance, but they are intended to enforce adherence to safety standards and protect the public from aviation-related risks.
In summary, the key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 facilitate the issuance of ADs to ensure aircraft safety, with CASA playing a critical role in assessing and implementing these directives. The obligations on CASA and other entities focus on maintaining airworthiness through compliance with international standards, and there are significant consequences for failing to adhere to these requirements.
