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 issued AD 94-01-04 affecting Honeywell Traffic Alert and Collision Avoidance Systems in 1994. The United States is the State of Design for this equipment. CASA has reassessed this AD and as a result has cancelled Australian AD/RAD/56. The cancellation will become effective on 28 September 2006. No replacement AD is required, as the original unsafe condition has been corrected by regulation 262AC of the Civil Aviation Regulations 1988.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, governs the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. One of the significant gaps this Act addresses is the need for a comprehensive framework to maintain the continuing airworthiness of aircraft. In line with this, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to enforce specific safety requirements for aircraft types and aeronautical products registered in Australia. These ADs are critical in ensuring that all aircraft continue to meet safety standards throughout their operational lives. The policy objective behind these regulations is to uphold the highest safety standards in civil aviation, aligning with Australia's commitments under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. This authority is exercised under section 98 of the Act, with the overarching objective of maintaining the safety of air navigation. An AD, as defined under subregulation 39.001(5), is classified as a disallowable instrument and is subject to the provisions of the Legislative Instruments Act 2003, thus making it a legislative instrument. ADs are a critical component of the international framework for continuing airworthiness, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds primary responsibility for the airworthiness of an aircraft type and must provide necessary information to the States of Registry. CASA, acting as Australia’s national airworthiness authority, is obligated to assess such information and, if deemed necessary, issue corresponding Australian ADs to enforce the requirements stipulated by the State of Design. This legislative framework applies to all entities involved in the design, registration, and operation of aircraft within Australia, ensuring compliance with both national and international safety standards.
Key Provisions
The Civil Aviation Act 1988 provides the framework under which the Civil Aviation Safety Regulations 1998 operate, particularly concerning the issuance of airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. This regulation is further clarified by subregulation 39.001(5), which stipulates that ADs are disallowable instruments under the Acts Interpretation Act 1901 and, as such, are considered legislative instruments under the Legislative Instruments Act 2003. These provisions are crucial as they establish the legal basis for CASA to enforce airworthiness standards and ensure the safety of aircraft operating within Australia.
The obligations placed on parties and entities governed by these regulations are significant. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 of the Convention on International Civil Aviation. This responsibility includes providing necessary information to the State of Registry to ensure compliance with airworthiness standards. The State of Registry, in this case, CASA, must then assess this information and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This process ensures that all aircraft registered in Australia meet the safety standards required by international and domestic regulations.
Non-compliance with ADs can lead to serious legal consequences. Breaches of these regulations can result in both civil and criminal penalties. For example, failure to comply with an AD can lead to enforcement actions against the aircraft operator, potentially resulting in fines or other sanctions. Additionally, in severe cases, non-compliance can lead to criminal charges, with penalties that may include substantial fines and imprisonment. These measures underscore the importance of adhering to ADs to maintain the highest standards of aviation safety.
The cancellation of an AD, such as Australian AD/RAD/56, which was cancelled due to changes in the regulatory environment and in response to an AD issued by the United States Federal Aviation Administration, also follows specific procedures. As per the Civil Aviation Act 1988, these cancellations are managed by CASA, ensuring that the cancellation aligns with international obligations and safety standards. The decision to cancel an AD without public consultation is justified by the nature of the AD and the international obligations under the Convention on International Civil Aviation. Additionally, the Office of Regulatory Review has determined that such ADs do not require a Regulatory Impact Statement, streamlining the process while maintaining safety standards.
