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. 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-2005-076 affecting Eurocopter EC 120 model helicopters. France is the State of Design for Eurocopter EC120 Helicopters. CASA has assessed this AD and has issued Australian AD/EC 120/14, original issue, which will become effective on 13 May 2005.
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, enacted by the Commonwealth Parliament, aims to regulate civil aviation in Australia and ensure the safety of air navigation. Under this Act, the Governor-General has the authority to make regulations, including issuing airworthiness directives (ADs) for certain aircraft or aeronautical products as stipulated in the Civil Aviation Regulations 1998. These ADs are legislative instruments that mandate requirements to ensure the continuing airworthiness of aircraft. The Civil Aviation Safety Authority (CASA) acts as Australia’s national airworthiness authority and is responsible for assessing and implementing ADs issued by the State of Design, such as the French DGAC, which is the State of Design for Eurocopter EC 120 helicopters. This process is in line with Australia’s obligations under the Convention on International Civil Aviation, where the State of Design has the responsibility for continuing airworthiness and must provide necessary information to appropriate States of Registry.
Scope and Application
The Civil Aviation Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives are legislative instruments and are subject to disallowance. The ADs are typically issued in response to continuing airworthiness concerns and must comply with international standards set forth in Annex 8 of the Convention on International Civil Aviation. In the case of aircraft designed by a State other than Australia, such as the Eurocopter EC 120 model helicopters designed by France, CASA must evaluate the relevant ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. This process underscores the collaborative nature of international aviation safety regulations and the obligation of each State of Registry to maintain the airworthiness of aircraft registered within its jurisdiction. The issuance of an Australian AD, like AD/EC 120/14, is a direct consequence of Australia's commitment to international aviation standards and does not necessitate public consultation or a Regulatory Impact Statement.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 (subsection 84A(2)) enable the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives are legislative instruments designed to ensure the continuing airworthiness of aircraft. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific kinds of aircraft or aeronautical products, which are integral to maintaining safety in air navigation. The authority to issue these directives is grounded in the overarching responsibility of the State of Design to provide necessary information for the continuing airworthiness of aircraft types, as stipulated in Annex 8 to the Convention on International Civil Aviation.
The Act and the accompanying regulations impose several obligations on the parties and entities they govern. Primarily, the State of Design, in this case, France for the Eurocopter EC 120 model, must provide information to ensure the continuing airworthiness of the aircraft type. This includes issuing ADs when necessary. The State of Registry, here represented by Australia through CASA, must assess the ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs. These ADs mandate specific requirements for the continuing airworthiness of the aircraft registered within the State of Registry. Furthermore, CASA is responsible for ensuring that all aircraft registered in Australia meet the continuing airworthiness standards set forth in the relevant ADs.
Failure to comply with the requirements set out in an AD can result in significant consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline the penalties for non-compliance with ADs; however, general aviation regulations and safety standards imply severe repercussions. Civil penalties can include fines and sanctions against the aircraft operator or owner, while criminal penalties may include imprisonment, reflecting the seriousness of neglecting safety directives. CASA has the authority to take enforcement actions against non-compliant aircraft, potentially grounding them until the required compliance measures are met. These measures underscore the importance of adhering to ADs to maintain the high safety standards mandated by Australian aviation law.
