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 2009-02-06 R1 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/354, Amendment 1, which will become effective on
23 September 2009. 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Initial Airworthiness, in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety and efficiency of civil aviation within Australia, addressing the need for comprehensive regulatory frameworks governing air navigation and safety. In line with this, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed rules for maintaining airworthiness and safety standards in civil aviation. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations necessary for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. This legislative framework ensures that Australia meets its international obligations under the Convention on International Civil Aviation and maintains the continuing airworthiness of aircraft registered in Australia. The ADs, as legislative instruments, are issued by CASA to mandate safety requirements derived from ADs issued by the State of Design, thereby maintaining safety and compliance with international standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority granted by the Civil Aviation Act 1988, permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These directives are legislative instruments and are issued to ensure the safety of air navigation. This legislation applies to entities involved in the manufacture, registration, and operation of aircraft within Australia, as CASA is the national airworthiness authority responsible for the continuing airworthiness of aircraft on the Australian Register. The geographic reach of these regulations is national, with specific focus on aircraft registered within Australia. The ADs are issued in response to international obligations under the Convention on International Civil Aviation, particularly the responsibilities of the State of Design and the State of Registry. The ADs are designed to harmonise with international standards, and in this instance, CASA has issued an Australian AD in response to a corresponding AD issued by the United States Federal Aviation Administration for Boeing B737 model aircraft. Exemptions or exclusions from these ADs are not specified within the scope of this particular directive, and any potential exclusions would need to be assessed on a case-by-case basis by CASA. The authority to issue these directives extends through subordinate instruments as specified under the Civil Aviation Safety Regulations 1998.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that must be assessed and potentially adopted by CASA when the State of Design issues them, as seen in the case of the Boeing B737 model aircraft (sections 98, 39.001, 39.001(5)). The authority to issue such directives is rooted in the overarching goal of ensuring the safety of air navigation as stipulated in the Civil Aviation Act 1988. The ADs serve as a mechanism for the continuing airworthiness of aircraft types, a responsibility primarily held by the State of Design but enforced by the State of Registry, which in Australia’s case, is CASA.
The obligations imposed by these regulations are multifaceted. The State of Design must provide necessary information to maintain the airworthiness of an aircraft type, and CASA is obligated to assess and, if necessary, issue corresponding ADs for aircraft registered in Australia. This process ensures that Australian aircraft meet international safety standards as outlined in Annex 8 of the Convention on International Civil Aviation. CASA’s role is pivotal as it not only assesses the ADs issued by the State of Design but also ensures that the mandated requirements are effectively communicated and enforced within the Australian aviation sector.
Breaches of the requirements set forth in the ADs could lead to serious consequences. While the specific offences, penalties, or civil/criminal consequences for non-compliance are not detailed in the provided text, it is implicit that failure to adhere to these safety mandates could result in significant regulatory action. Non-compliance with ADs could potentially lead to aircraft being grounded or operations being restricted, which could have severe repercussions for both the operators and the broader aviation industry. The seriousness of such breaches underscores the importance of strict adherence to the directives issued by CASA.
Additionally, under the Legislative Instruments Act 2003, ADs are disallowable instruments, meaning that they can be disallowed by either House of Parliament. This legislative oversight ensures that the directives issued by CASA align with broader legislative intent and public interest, providing an additional layer of accountability. The lack of public consultation and a Regulatory Impact Statement for this specific AD indicates a streamlined process aimed at promptly addressing safety concerns, reflecting the critical nature of the information and the urgency with which it must be acted upon.
