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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 of France has issued AD F-2004-192 affecting Arriel 2S1 turboshaft engines. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ARRIEL/20, which will become effective on 17 February 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 Acting Section Head - Airframes, Airworthiness Standards Branch, Standards Division, 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 framework for the regulation of civil aviation in Australia, focusing on safety and efficiency. This legislation empowers the Governor-General to create regulations under section 98, aiming to ensure the safety of air navigation. In line with this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thus maintaining the continuing airworthiness of aircraft registered in Australia. The authority to issue these ADs is derived from the overarching responsibility of the State of Design under Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information to ensure the airworthiness of a particular aircraft type. The Civil Aviation Act 1988, therefore, ensures that Australia meets its international obligations while upholding stringent safety standards within its jurisdiction.
Scope and Application
The Civil Aviation Regulations 1998, made under the Civil Aviation Act 1988, provide the framework for the issuance of airworthiness directives (ADs) concerning various types of aircraft and aeronautical products. These regulations apply to entities such as aircraft manufacturers, operators, and maintenance providers who must comply with ADs to ensure the safety and airworthiness of aircraft registered in Australia. The geographic and jurisdictional reach of these regulations is national, as Australia, through the Civil Aviation Safety Authority (CASA), adheres to international standards set by the International Civil Aviation Organization (ICAO) and implements these standards domestically. Specifically, the ADs issued by CASA are mandated by Australia's obligations under the Convention on International Civil Aviation. Exclusions or exemptions from ADs are not explicitly mentioned, suggesting that compliance is generally mandatory for all relevant entities. The regulations also extend their application through subordinate instruments, allowing CASA to adapt and issue specific ADs as needed based on international ADs issued by the State of Design.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Regulations 1998, particularly section 98 and regulation 39.001, establish the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives are designed to ensure the continuing airworthiness of aircraft and aeronautical products in Australia, aligning with international standards set by the International Civil Aviation Organization (ICAO). Section 98 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 provides CASA with the authority to issue ADs for specific types of aircraft or aeronautical products. This ensures that any identified safety issues are addressed promptly and effectively.
Under these provisions, the State of Design—the country where the aircraft is designed—has the primary responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to the State of Registry—the country where the aircraft is registered—to maintain the aircraft's airworthiness. CASA, as Australia’s national airworthiness authority, must evaluate any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to enforce the required safety measures. For example, in response to AD F-2004-192 issued by France concerning Arriel 2S1 turboshaft engines, CASA issued Australian AD/ARRIEL/20, effective from 17 February 2005.
The obligations imposed by these regulations on CASA and other relevant entities include thorough assessment and compliance with international standards. CASA must review ADs issued by other States of Design to ensure they meet the necessary safety requirements and then issue corresponding Australian ADs if deemed necessary. This process ensures that all aircraft registered in Australia meet the required safety standards. The State of Registry must also develop or adopt requirements to ensure the continuing airworthiness of aircraft, and CASA must enforce these requirements through the issuance of ADs when necessary.
Failure to comply with ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to significant penalties, including fines and imprisonment. The specific penalties depend on the severity of the breach and the provisions of the Act. Additionally, operators who do not adhere to ADs may face aircraft grounding or other enforcement actions by CASA, potentially leading to operational disruptions and safety risks. It is crucial for all parties involved to understand and comply with these directives to maintain the highest safety standards in aviation.
