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 Japanese JCAB has issued AD TCD-5230-2000 affecting Fuji FA-200 model aircraft. Japan is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/FA-200/26, which will become effective on 30 July 2009.
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 Manager, Airframes& Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a regulatory framework for ensuring the safety and efficiency of civil aviation in Australia. The Act empowers the Governor-General to make regulations under section 98, specifically to address safety concerns in air navigation. The Civil Aviation Safety Regulations 1998 further delineate the processes for issuing airworthiness directives (ADs) through regulation 39.001, which are critical for maintaining the continuing airworthiness of aircraft. The ADs, as per subregulation 39.001(5), are considered disallowable instruments under the Acts Interpretation Act 1901 and are legislative instruments in accordance with the Legislative Instruments Act 2003. The issuance of ADs aligns with Australia’s obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design, in this case Japan, holds primary responsibility for the continuing airworthiness of aircraft types. CASA, acting as Australia's national airworthiness authority, must assess and, if necessary, issue Australian ADs to enforce the requirements set forth by the State of Design.
Scope and Application
The Civil Aviation Safety 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. The ADs serve as a mechanism for the continuing airworthiness of aircraft, with the State of Design holding primary responsibility for the airworthiness of an aircraft type and the State of Registry being responsible for the airworthiness of individual aircraft. In instances where a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. For instance, in response to AD TCD-5230-2000 issued by Japan concerning Fuji FA-200 model aircraft, CASA has issued Australian AD/FA-200/26, effective from 30 July 2009. Given that this AD is issued under Australia’s obligations under the Convention on International Civil Aviation and in response to an AD by the relevant State of Design, no public consultation has taken place. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the issuance of airworthiness directives (ADs). Section 98 of the Act grants the Governor-General the authority to make regulations in the interest of air navigation safety, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and consequently, a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
Under these provisions, CASA is tasked with ensuring the continuing airworthiness of aircraft registered in Australia. This includes assessing ADs issued by the State of Design, which is responsible for the overall airworthiness of an aircraft type, and issuing corresponding Australian ADs when necessary. This obligation is particularly relevant under Annex 8 to the Convention on International Civil Aviation, which assigns responsibilities to both the State of Design and the State of Registry for ensuring that aircraft maintain their airworthiness. The State of Registry, in this case CASA, must develop or adopt requirements to maintain airworthiness, and must respond to ADs issued by the State of Design by potentially issuing its own directives.
Failure to comply with the requirements set out in an AD can lead to serious consequences. Non-compliance with ADs may result in penalties, as ADs are legally binding. While the specific penalties are not detailed in the provided text, it is understood that breaches of ADs can lead to enforcement actions, including fines and other civil or criminal penalties as prescribed by the relevant aviation regulations. The seriousness of these consequences underscores the importance of adhering to ADs to maintain the safety of air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a structured approach for the issuance and enforcement of airworthiness directives, ensuring that aircraft registered in Australia meet safety standards. CASA's role in assessing and issuing these directives is critical, given its responsibility for air navigation safety and its obligations under international conventions. Compliance with ADs is mandatory, and failure to do so can result in significant legal and financial repercussions.
