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 European Aviation Safety Authority (EASA) has issued AD 2008-0013 affecting Dassault Aviation Mystère-Falcon 900 and Falcon 900EX model aircraft. The EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/AMD 50/44, which will become effective on 13 March 2008.
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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, 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 legislative framework for the regulation of civil aviation in Australia, focusing on ensuring the safety and efficiency of air navigation. In the interests of safety, the Act allows for the creation of regulations by the Governor-General, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific kinds of aircraft or aeronautical products. This legislative mechanism facilitates the alignment of Australian aviation safety standards with international obligations, particularly under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type. CASA, acting as Australia’s national airworthiness authority, must ensure compliance with these international standards by issuing corresponding Australian airworthiness directives when necessary. This approach ensures that Australian-registered aircraft meet the requisite safety standards, aligning with global best practices and obligations under international agreements.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) which are legislative instruments aimed at ensuring the safety of air navigation. Under these regulations, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products, with such directives being a critical component of maintaining the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation. The ADs are issued in response to directives from the State of Design or based on CASA's own assessments, ensuring that Australian aircraft meet international safety standards. The ADs do not require consultation with the Australian public as they are issued in accordance with Australia's obligations under international conventions, and they do not necessitate a Regulatory Impact Statement. The issuance of these directives is governed by the provisions of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, with the specific authority to issue such directives being vested in CASA as Australia’s national airworthiness authority.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (39.001). This authority is exercised under the overarching framework of the Civil Aviation Act 1988, where section 98 allows the Governor-General to create regulations for air navigation safety (98). Importantly, ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as per section 6 of the Legislative Instruments Act 2003 (39.001(5)). This regulatory structure ensures that ADs are formally recognised and enforceable under Australian law.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties governed by these provisions are significant. For instance, the State of Design, which in this context is France for Dassault Aviation Mystère-Falcon 900 and Falcon 900EX model aircraft, has the responsibility to provide necessary information to ensure the continuing airworthiness of the aircraft type (Annex 8). The State of Registry, which is Australia in this scenario, must adopt or develop requirements to ensure the airworthiness of the aircraft registered within its territory (Annex 8). CASA, as Australia’s national airworthiness authority, must evaluate any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the required safety measures.
Failure to comply with the provisions outlined in the Civil Aviation Safety Regulations 1998 can lead to serious consequences. While specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with ADs can result in significant safety risks. CASA’s authority to issue ADs and enforce them underscores the critical nature of adherence to these directives. Regulatory oversight ensures that all parties involved—including aircraft manufacturers, operators, and regulatory bodies—are held accountable for maintaining the highest safety standards in air navigation.
