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 United States FAA has issued AD 2006-04-13 affecting Gulfstream Model GIV-X and GV-SP aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/G1159/45, which will become effective on 22 March 2006.
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 by the Australian Parliament, is foundational legislation that governs civil aviation within Australia, with a primary focus on ensuring the safety of air navigation. The Act provides the authority for the Civil Aviation Safety Regulations 1998, which in turn empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. These ADs are considered legislative instruments and are necessary for maintaining the continuing airworthiness of aircraft types, in accordance with international standards set by the Convention on International Civil Aviation. The ADs serve as a crucial mechanism for CASA to enforce compliance with safety requirements set by the aircraft's State of Design, thereby fulfilling Australia's obligations under international aviation agreements and ensuring that aircraft operating within Australian airspace meet stringent safety standards.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, formulated to uphold the safety of air navigation, as mandated by section 98 of the Civil Aviation Act 1988. This legislative framework applies to all aircraft registered in Australia, irrespective of their design origin, and mandates the State of Registry to ensure the aircraft's ongoing airworthiness. In instances where the State of Design issues an AD, CASA, as Australia's national airworthiness authority, is obligated to assess the directive and, if deemed necessary, issue an Australian AD to enforce the design state's requirements on aircraft registered in Australia. The issuance of these directives is conducted in accordance with international standards set forth by the Convention on International Civil Aviation, specifically Annex 8, which delineates the responsibilities of both the State of Design and the State of Registry concerning the airworthiness of aircraft types.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that ensure the safety of air navigation, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific types of aircraft or aeronautical products. The ADs are legislative instruments as per section 6 of the Legislative Instruments Act 2003, and they are essential for maintaining the continuing airworthiness of aircraft as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and the Regulations are significant. The State of Design, in this case, the United States, has the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to ensure safety. The State of Registry, in this instance, Australia, must then develop or adopt requirements to maintain the airworthiness of the aircraft. When a State of Design issues an AD, CASA, as the national airworthiness authority, is obligated to assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian registered aircraft meet the required safety standards.
The issuance of an AD mandates compliance and carries specific obligations for those affected. For example, aircraft operators must follow the AD's requirements, which may include inspections, maintenance actions, or modifications to the aircraft. Failure to comply with an AD can lead to severe consequences, including potential grounding of the aircraft, which could result in significant operational disruptions and financial penalties. The ADs are designed to address safety issues promptly and effectively, ensuring that all aircraft maintain their airworthiness and continue to operate safely.
Under the Civil Aviation Safety Regulations 1998, there are also provisions for penalties and consequences for non-compliance with ADs. While the specific penalties are not detailed in the provided text, generally, non-compliance with ADs can lead to civil penalties, such as fines, and in more serious cases, criminal penalties. Additionally, aircraft found to be non-compliant could be subject to grounding until the necessary actions are taken to rectify the issues identified in the AD. The enforcement of these penalties is intended to ensure adherence to safety regulations and to maintain the highest standards of aviation safety.
