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 AD 2007-24-02 affecting Boeing 737 series aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/303, Amendment 2, which will become effective on 13 March 2008. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies 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 framework for civil aviation in Australia, ensuring the safety, efficiency, and orderly growth of the industry. It empowers the Governor-General to make regulations necessary for the safety of air navigation, which includes the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901. The objective of these regulations is to align with international standards set by the Convention on International Civil Aviation, particularly ensuring the continuing airworthiness of aircraft types and individual aircraft registered in Australia. CASA, as the national airworthiness authority, is tasked with assessing and, where necessary, issuing Australian airworthiness directives in response to directives from the relevant State of Design, such as the United States for Boeing 737 series aircraft.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, which pertain to the issue of airworthiness directives (ADs), apply to all aircraft and aeronautical products within Australia. Pursuant to the Civil Aviation Act 1988, the Governor-General has the authority to establish these regulations, which are intended to enhance the safety of air navigation. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. The State of Registry, which in this case is represented by the Civil Aviation Safety Authority (CASA), is responsible for ensuring the continuing airworthiness of aircraft registered in Australia. CASA issues these directives to comply with international obligations under the Convention on International Civil Aviation and to address specific airworthiness concerns identified by the aircraft's State of Design. For example, CASA issued AD/B737/303, Amendment 2, in response to an AD from the United States Federal Aviation Administration for Boeing 737 series aircraft. Given that these directives are issued in adherence to international standards and in response to directives from the aircraft’s State of Design, they do not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows CASA to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are treated as legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to act on ADs issued by the State of Design, which is the country where the aircraft type is designed. CASA must evaluate the information provided in the foreign AD and, if necessary, issue a corresponding Australian AD to ensure compliance with the requirements set forth by the State of Design. This process is crucial for maintaining the continuing airworthiness of aircraft registered in Australia, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. As the national airworthiness authority, CASA’s role is to safeguard the safety standards of Australian-registered aircraft by adopting and enforcing ADs.
There are significant consequences for non-compliance with ADs. Any person who contravenes an AD is subject to enforcement actions, including potential fines and other penalties as stipulated by the regulations. The specific penalties can vary depending on the nature and severity of the breach but may include substantial monetary fines and, in some cases, criminal charges. These measures are in place to ensure that all parties adhere to the stringent safety standards mandated by CASA and the international conventions governing civil aviation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower CASA to issue ADs in response to international safety directives, ensuring the continuing airworthiness of aircraft registered in Australia. CASA’s obligations include evaluating and implementing these ADs to maintain high safety standards. Failure to comply with these directives can result in serious legal and financial penalties, underscoring the importance of adherence to the regulations.
