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 US FAA has issued AD 2009-05-12 affecting Cessna 208 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CESSNA 208/25, which will become effective on 7 May 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 ensure the safety and efficiency of civil aviation within Australia. In line with this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Such ADs are critical for maintaining the continuing airworthiness of aircraft, as mandated by international standards set forth in Annex 8 to the Convention on International Civil Aviation. Under this convention, the State of Design holds primary responsibility for ensuring an aircraft type's airworthiness and must provide necessary information to States of Registry, who are then responsible for the individual aircraft's airworthiness. In practice, CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue ADs to enforce the requirements of the State of Design. This legislative framework ensures that Australian aviation remains compliant with international safety standards.
Scope and Application
The Civil Aviation Act 1988, as supported by the Civil Aviation Safety Regulations 1998, provides a framework through which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) aimed at ensuring the safety of air navigation. These regulations empower CASA to issue ADs for specific kinds of aircraft or aeronautical products, which are intended to address any safety concerns that may arise in the continuing airworthiness of these aircraft. The ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and they serve as legislative instruments in accordance with the Legislative Instruments Act 2003. The ADs are issued in response to the obligations under the Convention on International Civil Aviation and typically follow an AD from the State of Design. For instance, CASA has issued Australian AD/CESSNA 208/25 in response to the US Federal Aviation Administration's AD 2009-05-12, which pertains to the Cessna 208 model aircraft. The issuing of these directives is conducted by CASA's Airframes & Structures division and adheres to the provisions outlined in the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, section 98 of the Act allows the Governor-General to make regulations for safety, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products (sections 98 and 39.001). These ADs are legislative instruments, as outlined in subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003.
Under these provisions, the State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure safety, as per Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is responsible for the individual aircraft's airworthiness, must then develop or adopt requirements to maintain the aircraft's airworthiness. When the State of Design issues an AD, CASA must assess the information and, if appropriate, issue an Australian AD to enforce the State of Design’s requirements (Annex 8). For example, the Federal Aviation Administration (FAA) in the United States issued AD 2009-05-12 affecting Cessna 208 model aircraft. CASA assessed this AD and issued Australian AD/CESSNA 208/25, which became effective on 7 May 2009.
The Act and Regulations impose specific obligations on CASA and other entities. CASA must assess ADs issued by the State of Design and, if necessary, issue Australian ADs to ensure compliance with safety standards. The State of Registry is required to implement the ADs to maintain the continuing airworthiness of aircraft registered within its jurisdiction. These obligations are crucial to maintaining international safety standards and ensuring that aircraft are operated safely.
Breaching the provisions of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998 can lead to serious legal consequences. While the specific offences and penalties are not detailed in the provided text, generally, non-compliance with aviation regulations can result in significant fines, imprisonment, or both. For instance, failing to comply with an AD can result in the grounding of an aircraft or prosecution under the Act, which may lead to substantial penalties depending on the severity of the breach. The exact penalties are determined by the courts and can vary widely based on the specific circumstances of the offence.
