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/CESSNA 150/20, affecting Cessna 170 series aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
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 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing the need for a cohesive set of laws to ensure safety, efficiency, and orderly growth in the aviation industry. The Act establishes the Civil Aviation Safety Authority (CASA) as the primary regulator responsible for overseeing and enforcing aviation safety and standards. A significant element of this legislative framework is the Civil Aviation Safety Regulations 1998, which includes provisions for the issuance of airworthiness directives (ADs). ADs are regulatory instruments issued by CASA to mandate safety measures concerning specific types of aircraft or aeronautical products, ensuring that they meet continuing airworthiness standards. The objective of these regulations is to align with international standards set by the International Civil Aviation Organization (ICAO), thereby enhancing the safety and uniformity of aviation practices across jurisdictions. The Act empowers CASA to issue such directives in the interest of aviation safety, reflecting a policy objective to maintain the highest safety standards in Australia’s civil aviation sector.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for the regulation of airworthiness in Australia, with the Civil Aviation Safety Authority (CASA) as the national airworthiness authority responsible for issuing airworthiness directives (ADs). These ADs apply to specific kinds of aircraft or aeronautical products as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998, and are made under section 98 of the Civil Aviation Act 1988 for the purpose of ensuring the safety of air navigation. Notably, these ADs are legislative instruments and are disallowable instruments under section 46A of the Acts Interpretation Act 1901. The scope of these regulations encompasses all aircraft registered in Australia, extending to the continuing airworthiness responsibilities of both the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. The application of these regulations is national, covering all aircraft and aeronautical products within Australia's jurisdiction. The regulations do not specify exclusions or thresholds but allow for the issuance of ADs based on the necessity to address specific safety issues. The authority to issue or cancel ADs is exercised by CASA, which in this instance, has decided to cancel AD/CESSNA 150/20 for the Cessna 170 series aircraft, effective from 17 January 2008, due to the resolution of the original unsafe condition by another AD. This decision was made without public consultation as it reduces regulatory burden, and the Office of Best Practice Regulation has deemed that such ADs do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide the framework within which airworthiness directives (ADs) are issued and managed in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular kinds of aircraft or aeronautical products. Furthermore, under subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments as defined by section 6 of the Legislative Instruments Act 2003. These ADs are essential for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations under these regulations necessitate that CASA, as Australia’s national airworthiness authority, must assess any AD issued by a State of Design that affects aircraft on the Australian Register. If necessary, CASA is required to issue corresponding Australian ADs to enforce the requirements set forth by the State of Design. This process ensures that Australian-registered aircraft meet international safety standards. For instance, CASA issued AD/CESSNA 150/20 in 1971, which affected Cessna 170 series aircraft. After reviewing this directive, CASA decided to cancel it, effective from 17 January 2008, as the unsafe condition it targeted is now addressed by AD/GENERAL/74 Amendment 1. This decision was made without public consultation, as it reduces the regulatory burden, and no Regulatory Impact Statement was required, as determined by the Office of Best Practice Regulation.
Breaching the requirements of ADs can lead to significant legal consequences. Non-compliance with ADs may result in both civil and criminal penalties, depending on the severity of the breach and the associated risk to safety. Under the Civil Aviation Act 1988, individuals or entities that fail to comply with ADs can face substantial fines and, in severe cases, imprisonment. The specific penalties are not detailed within the text but generally reflect the gravity of the non-compliance and its potential impact on aviation safety. CASA, as the enforcing authority, plays a crucial role in ensuring that ADs are adhered to, thereby maintaining high safety standards in the aviation sector.
