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 EASA has issued AD 2006-0164 affecting Eurocopter AS 350 and AS 355 model aircraft. EASA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/ECUREUIL/111 Amendment 1 and AD/AS 355/87 Amendment 1, which will become effective on 28 June 2006. These ADs cancel and replace the previous issues.
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 to govern civil aviation within Australia, was introduced to ensure the safety and efficiency of civil aviation in the country. The Act provides the legislative framework for the regulation of civil aviation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). As part of the Act, the Governor-General has the authority to make regulations for air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specified types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003 and are essential for maintaining the continuing airworthiness of aircraft, in alignment with international standards set by the International Civil Aviation Organization (ICAO). This AD, issued by CASA in response to an AD from the European Aviation Safety Agency (EASA), exemplifies the collaborative effort between nations to uphold international aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998 apply to all individuals, entities, and aircraft within Australia, extending to any aircraft registered in Australia regardless of where they are located or operating. This includes both commercial and private aircraft, as well as aeronautical products. The geographic reach of these regulations is national, as Australia is a signatory to the Convention on International Civil Aviation, which mandates the adoption and enforcement of such safety measures. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives to ensure the safety of air navigation. These directives are legislative instruments, disallowable under the Acts Interpretation Act 1901, and subject to the Legislative Instruments Act 2003. The regulations do not explicitly state exclusions or thresholds but apply broadly to all aircraft types and aeronautical products within Australia. The authority to issue airworthiness directives can be extended or restricted through subordinate instruments, such as the issuance of specific directives responding to international obligations or findings by the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore, they are classified as legislative instruments as per section 6 of the Legislative Instruments Act 2003. In line with Annex 8 to the Convention on International Civil Aviation, the State of Design holds the overarching responsibility for the continuing airworthiness of an aircraft type, and must supply any necessary information to ensure that type's airworthiness to the appropriate States of Registry. The State of Registry, on the other hand, is responsible for the continuing airworthiness of individual aircraft, and must establish or adopt requirements to ensure this airworthiness.
Obligations and requirements imposed by these provisions mandate that the State of Design, like the European Aviation Safety Agency (EASA) in this instance, must issue ADs to address safety concerns specific to a type of aircraft. The State of Registry, in this case CASA as Australia’s national airworthiness authority, must assess the information contained in any AD issued by the State of Design. If deemed appropriate, CASA must then issue an Australian AD to enforce the requirements of the State of Design. This process ensures that the safety measures established by the State of Design are implemented in the Australian context, maintaining the integrity and safety of air navigation within Australia.
Failure to comply with an airworthiness directive can result in significant legal consequences. The Civil Aviation Safety Regulations 1998 stipulate that non-compliance with an AD can lead to severe penalties. Under regulation 39.005, the maximum penalty for contravening an AD is a fine of up to 10,000 penalty units, which translates to a substantial financial penalty given the current penalty unit value. Additionally, individuals or entities found to be in breach of an AD may face civil or criminal proceedings, leading to further financial and reputational consequences. These stringent measures underscore the importance of adhering to airworthiness directives to maintain the highest standards of aviation safety.
