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.
CASA issued AD/DH 82/14, affecting De Havilland DH 82 model aircraft in 2005. This AD was based on UK AD G-2005-0025. The UK, the State of Design for this type, has now cancelled their AD. As a result, CASA has cancelled AD/DH 82/14. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the UK CAA has determined that normal maintenance practices will ensure airworthiness.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, enacted by the Parliament of Australia, serves to regulate civil aviation activities within the country, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to establish regulations under section 98, which is pivotal in the governance of airworthiness standards and safety protocols. In line with this mandate, the Civil Aviation Safety Regulations 1998 were introduced, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products through regulation 39.001. The ADs are instrumental in maintaining the continuing airworthiness of aircraft types registered in Australia and are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Act 1988, therefore, fills a critical gap by providing a legal framework that ensures Australian civil aviation practices align with both national safety standards and international conventions.
Scope and Application
The Civil Aviation Act 1988, as amended and implemented through the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for types of aircraft or aeronautical products. These directives are legislative instruments that fall under the purview of section 46A of the Acts Interpretation Act 1901 and are subject to disallowance. Furthermore, under the Legislative Instruments Act 2003, ADs are recognised as legislative instruments. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, as per Annex 8 to the Convention on International Civil Aviation, and must furnish any necessary information to ensure the continuing airworthiness of the type to the appropriate States of Registry. Conversely, the State of Registry holds the responsibility for the ongoing airworthiness of individual aircraft. CASA, acting as Australia’s national airworthiness authority, must evaluate any information provided by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design. This legislative framework ensures that airworthiness directives are a critical tool in maintaining the safety standards of aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs). Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations that serve the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and hence, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these legislative provisions include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Design must furnish necessary information to the appropriate States of Registry to maintain the airworthiness of the aircraft type. The State of Registry, in turn, has the duty to develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction. When a State of Design issues an AD against a type of aircraft registered in Australia, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the State of Design's requirements.
Failure to comply with the ADs can result in various consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail offences, penalties, or civil/criminal consequences for non-compliance with ADs; however, non-compliance generally results in the aircraft being considered unairworthy. This can lead to severe repercussions, including potential grounding of the aircraft, legal action against the aircraft owner or operator, and possible civil or criminal penalties as determined by the relevant aviation authorities. The specific penalties are not detailed within these sections but are typically covered under other parts of the Civil Aviation Act 1988 and associated regulations, which may include fines or imprisonment for serious violations.
