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 DGAC has issued AD 74-79-6 affecting Eurocopter SA315 helicopters. France is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/SA 315/18 which will become effective on 5 July 2007.
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, New Technologies and Systems, 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, enacted by the Parliament of Australia, provides the legal framework for ensuring the safety of air navigation in the country. One of the key mechanisms for this is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. ADs are legislative instruments created to mandate specific requirements for maintaining the airworthiness of aircraft, which is critical for ensuring public safety and meeting international obligations as stipulated in the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) has the authority to issue these directives, particularly when corresponding directives are issued by the State of Design, such as the recent AD/SA 315/18 for Eurocopter SA315 helicopters, which was issued following a similar directive from France. This directive exemplifies CASA's role in ensuring that Australian-registered aircraft meet international safety standards without necessitating public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988 and its accompanying Civil Aviation Safety Regulations 1998, specifically under section 98 and regulation 39.001 respectively, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products, which are legislative instruments under the Legislative Instruments Act 2003. This regulatory framework is rooted in international obligations, particularly under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type. Correspondingly, the State of Registry, which in the case of Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. The ADs serve as a crucial form of continuing airworthiness information. When an AD is issued by a State of Design, CASA must assess the information and, if deemed necessary, issue an Australian AD. This process is exemplified by the AD affecting Eurocopter SA315 helicopters, where France, as the State of Design, issued AD 74-79-6, prompting CASA to issue Australian AD/SA 315/18, effective from 5 July 2007. Given that this AD arises from Australia's international obligations and is in response to an AD by the relevant State of Design, there was no consultation with the Australian public, and the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement. The AD was made by the Manager, New Technologies and Systems, in CASA’s Manufacturing, Certification and New Technologies Office, pursuant to subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to establish regulations for the Act’s purposes, with a focus on ensuring the safety of air navigation. One of these regulations, section 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulatory framework ensures that aircraft maintain their airworthiness throughout their operational life. The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, as such, are legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. Under Annex 8 to the Convention on International Civil Aviation, the State of Design, in this case, France for Eurocopter SA315 helicopters, has the responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to the appropriate States of Registry. The State of Registry, which in this case is Australia, must then develop or adopt requirements to ensure the aircraft’s continuing airworthiness. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements of the State of Design.
Failing to comply with ADs can lead to serious consequences. The ADs are legally binding, and non-compliance may result in both civil and criminal penalties. The specific penalties are not detailed in the provided text, but generally, violations of aviation safety regulations can lead to fines, aircraft grounding, and even criminal charges against individuals or companies responsible for the non-compliance. The regulatory process ensures that ADs are issued in line with international conventions and are intended to maintain the highest standards of safety in aviation.
