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 European EASA has issued AD 2007-0311 affecting Eurocopter EC130B4 model helicopters. Europe is the State of Design for EC130B4 helicopter types. CASA has assessed this AD and has issued Australian AD/ECUREUIL/129 which will become effective on 4 January 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 Acting 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 Australian Parliament, provides the legislative framework for ensuring the safety of air navigation within Australia. This Act empowers the Governor-General to establish regulations aimed at enhancing the safety of air navigation. One of the key mechanisms through which this is achieved is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are critical tools for maintaining the continuing airworthiness of aircraft and aeronautical products, aligning with international obligations under the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), as Australia's national airworthiness authority, plays a pivotal role in assessing and issuing these directives to ensure compliance with both domestic and international safety standards. The ADs are considered legislative instruments under the Legislative Instruments Act 2003, reflecting their importance in the regulatory framework.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations, CASA is empowered to issue these directives for specified types of aircraft or aeronautical products, making ADs a legislative instrument as defined under the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft and are issued in compliance with the standards set out in Annex 8 to the Convention on International Civil Aviation, which assigns the responsibility of ensuring airworthiness to the State of Design and the State of Registry. For example, in response to an AD issued by the European Aviation Safety Agency (EASA) for Eurocopter EC130B4 helicopters, CASA has issued its own AD, AD/ECUREUIL/129, effective from 4 January 2008, following its assessment of the relevant safety information. This process highlights the international collaboration in ensuring airworthiness, while also underscoring that certain ADs, issued in direct response to international obligations and directives, do not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs). Specifically, section 98 of the Act empowers the Governor-General to make regulations to ensure air navigation safety, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Section 39.001(5) further clarifies that ADs are legislative instruments that can be disallowed under the Acts Interpretation Act 1901, and must be assessed under the Legislative Instruments Act 2003.
Under these provisions, CASA, as the national airworthiness authority, has the responsibility to assess information provided by the State of Design and, if necessary, issue an Australian AD to ensure compliance with international standards. This process is particularly relevant when the European Union Aviation Safety Agency (EASA) issues an AD, as was the case with AD 2007-03-11 for the Eurocopter EC130B4 model helicopters. Since this AD pertains to an aircraft type registered in Australia, CASA issued Australian AD/ECUREUIL/129, which came into effect on 4 January 2008. Importantly, due to the international nature of the AD, no public consultation was required, and the Office of Best Practice Regulation determined that a Regulatory Impact Statement was not necessary.
Entities governed by the Act, such as aircraft operators, must comply with any ADs issued by CASA. This includes adhering to the specific requirements outlined in the ADs, which may involve inspections, maintenance, repairs, or modifications to ensure the continuing airworthiness of their aircraft. Failure to comply with an AD can lead to serious consequences, including potential grounding of the aircraft and legal penalties. Under the Civil Aviation Act 1988, non-compliance with an AD can result in civil penalties, including fines of up to $165,200 for individuals and $826,000 for corporations, as well as potential criminal charges for serious breaches. These penalties underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
