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 Civil Aviation Safety Authority or its predecessors issued AD/BEECH 23/28 affecting Beech 23 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 23/28. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the sector. The Act grants the Governor-General the authority to make regulations under section 98, particularly to enhance the safety of air navigation. In line with these provisions, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, plays a pivotal role in assessing information from the State of Design and issuing ADs to ensure compliance with safety standards.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products, ensuring compliance with safety standards. These ADs are considered legislative instruments and are subject to disallowance as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The State of Design, typically the manufacturer's country, is responsible for ensuring the continuing airworthiness of aircraft types, while the State of Registry, in this case Australia, must enforce these safety requirements. CASA’s role includes assessing information from the State of Design and issuing Australian ADs when necessary, thereby fulfilling its obligations under the Convention on International Civil Aviation. The cancellation of AD/BEECH 23/28 affecting Beech 23 aircraft exemplifies CASA's responsibility to respond to international safety directives, with the decision made in accordance with the Act, without public consultation as ADs do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. According to subregulation 39.001(5), ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Act and Regulations require the State of Design to maintain the continuing airworthiness of an aircraft type and provide necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, must assess any foreign ADs issued against aircraft on the Australian Register and may issue corresponding Australian ADs to ensure compliance with the safety standards. This process ensures that aircraft registered in Australia meet the continuing airworthiness requirements set forth by the international standards under the Convention on International Civil Aviation.
The obligations on the entities governed by these provisions include adherence to ADs issued by CASA. Aircraft operators and owners must comply with ADs applicable to their aircraft, ensuring they undertake any required maintenance or modifications to maintain airworthiness. Failure to comply with ADs can result in serious safety risks and legal consequences. CASA has the authority to enforce compliance through various means, including inspections, audits, and penalties for non-compliance.
Under the Civil Aviation Act 1988, failure to comply with ADs may constitute an offence. The Act provides for both civil and criminal penalties for non-compliance with ADs. Civil penalties can include fines, and in severe cases, criminal penalties may apply, leading to imprisonment. The specific penalties are determined by the nature and severity of the breach, with maximum penalties outlined in the relevant sections of the Act and Regulations. These provisions underscore the importance of adhering to ADs to ensure the safety of air navigation and the public.
