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 Emergency AD 2007-06-52 affecting Boeing 737-800 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/301, Amendment 1, which will become effective on 19 March 2007. 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, 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 Australian Parliament, aims to ensure the safety of air navigation and the continuing airworthiness of aircraft within Australia. In line with this objective, the Act empowers the Governor-General to make regulations for the Act's purposes. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These directives are essential for maintaining safety standards and ensuring compliance with international civil aviation conventions, such as Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for the continuing airworthiness of aircraft types to the State of Design. In response to such international obligations and ADs issued by the State of Design, CASA assesses the relevant information and, if necessary, issues Australian ADs to enforce the required safety measures. This process ensures that Australia meets its international commitments while safeguarding the safety of air navigation within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the regulatory framework for the issuance of airworthiness directives (ADs) in Australia, overseen by the Civil Aviation Safety Authority (CASA). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products, which are intended to ensure the continuing airworthiness of these items. These directives are legislative instruments under the Legislative Instruments Act 2003 and must align with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the country where the aircraft is designed, is responsible for the continuing airworthiness of aircraft types, while the State of Registry, in this case, Australia, is tasked with implementing these requirements. CASA, as the national airworthiness authority, must evaluate information provided by the State of Design and, if necessary, issue corresponding ADs to enforce these requirements. For instance, following the United States Federal Aviation Administration's Emergency AD 2007-06-52 for Boeing 737-800 series aircraft, CASA issued Australian AD/B737/301, Amendment 1, which replaced the previous directive. This process reflects Australia’s commitment to international aviation safety standards and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to enact regulations for the safety of air navigation. Complementing this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are essential tools for maintaining airworthiness standards and are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus considered legislative instruments as per section 6 of the Legislative Instruments Act 2003.
In practical terms, these airworthiness directives serve to ensure the continuing airworthiness of aircraft. According to Annex 8 of the Convention on International Civil Aviation, the State of Design, which is the country where the aircraft was originally designed, holds primary responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to other States of Registry to maintain airworthiness. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, such as the one issued by the United States FAA for Boeing 737-800 series aircraft, CASA must evaluate this information and, if necessary, issue a corresponding Australian AD.
In this instance, CASA has issued Australian AD/B737/301, Amendment 1, which will become effective on 19 March 2007. This AD cancels and replaces the previous issue and is directly in response to the United States FAA Emergency AD 2007-06-52. Given that this AD is a direct result of international obligations and the need to respond to an AD issued by the relevant State of Design, no consultation with the Australian public was conducted. Additionally, the Office of Regulatory Review has confirmed that such ADs do not require a Regulatory Impact Statement. The AD was created by the Manager, New Technologies and Systems, within CASA’s Manufacturing, Certification and New Technologies Office, in accordance with subsection 84A(2) of the Act.
Failure to comply with an airworthiness directive can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance may lead to civil penalties, including fines, as well as potential criminal charges. The maximum penalties for contravening airworthiness regulations can be substantial, reflecting the high stakes involved in maintaining the safety of air navigation. CASA enforces these regulations rigorously to ensure that all aircraft meet the required safety standards, thereby protecting the public and maintaining the integrity of the aviation industry.
