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 2009-16-07 affecting Boeing 737 model aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/360, which will become effective on
22 October 2009.
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, Future Technology and Regulatory Trends in the Standards Development and Future Technology Division, 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 the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to make regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 further specify that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. This legislative framework allows CASA to mandate requirements for the continuing airworthiness of aircraft in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation. The ADs are issued to address safety concerns identified by the State of Design, and CASA, as Australia's national airworthiness authority, is responsible for assessing and issuing corresponding Australian ADs to ensure compliance with these international standards.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide the legislative framework under which airworthiness directives (ADs) are issued in Australia. The Act applies to all aircraft registered in Australia, as well as to the broader aviation industry, ensuring compliance with safety standards that are integral to the operation of civil aviation within the country. The ADs are legislative instruments that mandate specific actions or modifications to aircraft or aeronautical products to maintain their airworthiness. These directives are issued by the Civil Aviation Safety Authority (CASA), Australia’s national airworthiness authority, and are aligned with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The ADs are applicable to both the State of Design, which is responsible for the initial airworthiness of the aircraft type, and the State of Registry, which oversees the continuing airworthiness of individual aircraft. In practice, when a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess the directive and, if necessary, issue a corresponding Australian AD to enforce the required safety measures. This legislative mechanism ensures that Australian aviation maintains a high standard of safety in line with international conventions and standards.
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 types of aircraft or aeronautical products (regulation 39.001(1)). These directives are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 (section 6). The ADs are issued to ensure the continuing airworthiness of aircraft, in accordance with international obligations under the Convention on International Civil Aviation, specifically Annex 8. The State of Design, which is the country where the aircraft type was designed, has the primary responsibility for the continuing airworthiness of the aircraft type, while the State of Registry, which is the country where the aircraft is registered, has the responsibility for the individual aircraft’s continuing airworthiness. When a State of Design issues an AD, the State of Registry, in this case CASA, must assess the information and, if appropriate, issue a corresponding AD for their jurisdiction.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA include the responsibility to assess any AD issued by the State of Design that affects aircraft registered in Australia. If CASA determines that an AD is necessary, they must issue an Australian AD to mandate the requirements. This ensures that all aircraft registered in Australia comply with the continuing airworthiness standards set by the State of Design. CASA must also ensure that the AD is issued in accordance with the legislative requirements, including the consideration of relevant international obligations and standards.
Breaches of the airworthiness directives issued under the Civil Aviation Safety Regulations 1998 can result in significant consequences. Operationally, non-compliance with an AD can lead to the grounding of affected aircraft, which can have serious implications for airlines and passengers. From a legal perspective, operating an aircraft that does not comply with an AD may be considered an offence under the Civil Aviation Act 1988. The penalties for such offences can include substantial fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, but they can be significant, reflecting the critical importance of adhering to airworthiness directives for the safety of air navigation.
