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 2007-21-08 affecting Hawker Beechcraft Model Hawker 800XP aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/HS 125/181, which will become effective on 20 December 2007.
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 framework for civil aviation in Australia, ensuring safety and efficiency in air navigation and operations. One of the significant functions of this Act is to empower the Governor-General to make regulations in the interest of air navigation safety, as exemplified in the Civil Aviation Safety Regulations 1998. Specifically, the Act facilitates the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are legislative instruments designed to maintain the continuing airworthiness of aircraft and aeronautical products. These directives align with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design bear responsibility for providing continuing airworthiness information to States of Registry, including Australia. CASA, acting as Australia’s national airworthiness authority, is required to issue corresponding ADs when necessary, ensuring compliance with both national and international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These ADs apply to kinds of aircraft or aeronautical products as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998, and they are legislative instruments as per subregulation 39.001(5). The Act and its regulations apply to all entities and individuals involved in civil aviation within Australia, ensuring that the continuing airworthiness of aircraft and aeronautical products is maintained according to international standards. The issuance of ADs is in line with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the responsibility for the continuing airworthiness of an aircraft type. Consequently, CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue Australian ADs to align with directives from the State of Design. The geographic reach of these regulations is national, applying uniformly across Australia, and they are designed to uphold the safety standards expected in civil aviation. There are no exclusions or thresholds explicitly stated in the text, and the issuance of ADs does not require consultation with the Australian public or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to enact regulations aimed at enhancing the safety of air navigation. This framework is further detailed in regulation 39.001 of the Civil Aviation Safety Regulations 1998, where the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are essential tools for maintaining the safety and airworthiness of aircraft, ensuring that they continue to meet the required safety standards throughout their operational lives.
Airworthiness directives are legislative instruments, as stipulated under subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 and section 46A of the Acts Interpretation Act 1901. This legal status underscores their importance and enforceability within the regulatory framework. The State of Design, typically the country where the aircraft is designed, holds the primary responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. This responsibility includes providing necessary information to other States of Registry to ensure compliance with international safety standards. Similarly, the State of Registry, where the aircraft is registered, must implement measures to maintain the aircraft's airworthiness. CASA, as Australia's national airworthiness authority, plays a crucial role in this process by assessing ADs issued by other countries and, where necessary, issuing corresponding Australian ADs to mandate these safety requirements.
Under the Civil Aviation Act 1988, CASA is required to assess international ADs and may issue Australian ADs to enforce the same safety standards domestically. For example, the United States, as the State of Design for the Hawker Beechcraft Model 800XP aircraft, issued AD 2007-21-08. CASA evaluated this directive and issued Australian AD/HS 125/181, effective from 20 December 2007. Given that this AD responds to international obligations and is based on an AD from the relevant State of Design, no public consultation was conducted, and a Regulatory Impact Statement was deemed unnecessary by the Office of Best Practice Regulation. The AD was issued by the Acting Manager, Systems and New Technologies, in the Airworthiness Engineering Branch of CASA, in accordance with subsection 84A(2) of the Act.
Failure to comply with an airworthiness directive can lead to serious legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in significant penalties, including fines and potential imprisonment. The severity of the penalties depends on the nature and extent of the non-compliance. Additionally, non-compliance can result in the grounding of aircraft, which can have severe operational and financial repercussions for airlines and other operators. These stringent measures underscore the importance of adhering to ADs in maintaining the highest standards of aviation safety.
