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 2008-04-09 affecting Taylorcraft series aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/TAYLORCRAFT/1, Amendment 1, which will become effective on 10 April 2008. This AD cancels and replaces the previous issue.
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 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 legislative framework for the regulation of civil aviation in Australia, with an overarching emphasis on safety. Under this Act, the Governor-General has the authority to create regulations that serve the interests of safe air navigation, as outlined in section 98. The Civil Aviation Safety Regulations 1998 further detail the processes and requirements for ensuring aircraft safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are critical in maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The Australian government, through CASA, issues these directives in response to assessments of international ADs, ensuring that Australian-registered aircraft comply with global safety standards without necessitating public consultation due to their international obligations.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation within Australia. The Act applies to various entities involved in civil aviation, including aircraft manufacturers, operators, and regulatory authorities like the Civil Aviation Safety Authority (CASA). Specifically, the Act empowers CASA to issue airworthiness directives (ADs) to mandate safety requirements for particular types of aircraft or aeronautical products. These ADs, as legislative instruments, are issued to uphold international safety standards under Annex 8 to the Convention on International Civil Aviation, where the State of Design holds responsibility for the continuing airworthiness of an aircraft type. For aircraft registered in Australia, the State of Registry, represented by CASA, must ensure these standards are met. The ADs are typically issued in response to directives from the relevant State of Design, such as the US Federal Aviation Administration's AD 2008-04-09 affecting Taylorcraft series aircraft, which CASA then adapts and enforces within Australia. The legislative process for these ADs does not involve public consultation or a Regulatory Impact Statement, as they are integral to fulfilling Australia's international obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988, particularly in conjunction with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. These directives are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and are subject to the provisions of the Legislative Instruments Act 2003. An AD is a formal instruction issued by CASA for maintaining the airworthiness of certain aircraft or aeronautical products, and it is mandated by the State of Design's responsibility under Annex 8 to the Convention on International Civil Aviation.
In terms of obligations, CASA is tasked with assessing any airworthiness directives issued by the State of Design that pertain to aircraft types registered in Australia. If deemed necessary, CASA must then issue its own AD to enforce the State of Design's requirements. This process ensures that all aircraft registered in Australia meet the necessary safety standards as stipulated by international conventions and the State of Design. The State of Registry, in this case CASA, has the responsibility to ensure the continuing airworthiness of individual aircraft registered within its jurisdiction. This includes implementing any ADs that may affect these aircraft.
Failure to comply with an AD can result in severe consequences. Section 98 of the Civil Aviation Act 1988 allows for penalties to be imposed on individuals or entities that do not adhere to the airworthiness directives. These penalties can include both civil and criminal sanctions, depending on the severity of the breach and the discretion of the court. The specific penalties can vary but may include fines or imprisonment, highlighting the seriousness with which the Act treats non-compliance with airworthiness directives.
Additionally, CASA has determined that this specific AD, AD/TAYLORCRAFT/1, Amendment 1, does not require public consultation or a Regulatory Impact Statement as it is issued in accordance with Australia's international obligations and the requirements of the State of Design. The AD was drafted by the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with subsection 84A(2) of the Act. This procedural step ensures that the AD is issued with due authority and in compliance with the legislative framework governing civil aviation safety in Australia.
