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 2008-11-09 affecting Boeing B727 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B727/212, which will become effective on 31 July 2008.
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, Airframes 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 ensure the safety and efficiency of civil aviation in Australia. The 1988 Act allows the Governor-General to make regulations that serve the interests of air navigation safety, such as those found in the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. ADs are essential for maintaining the continuing airworthiness of aircraft and are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia's national airworthiness authority, must respond to ADs issued by the State of Design by assessing the information and, if necessary, issuing Australian ADs to enforce the requirements. The issuing of ADs is integral to Australia's obligations under the Convention on International Civil Aviation, and they are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation in Australia. Specifically, under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, particularly for enhancing the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products, making these directives legislative instruments as per section 46A of the Acts Interpretation Act 1901. These ADs are integral in maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Registry of an individual aircraft under Annex 8 of the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, must review any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the required safety measures. The process is driven by international obligations and the need to align with standards set by the International Civil Aviation Organization (ICAO). Consequently, no public consultation is required for such ADs, and they are issued directly by CASA as per the authority granted under the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 provides the framework for the regulation of civil aviation in Australia, and under section 98, the Governor-General has the authority to make regulations that serve 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 airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. These directives are critical for ensuring the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003.
An airworthiness directive, as outlined in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, is a formal and enforceable requirement issued by CASA. When CASA issues an AD, it is doing so in response to its obligations under international agreements, specifically Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case, the USA for Boeing B727 model aircraft, has the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to ensure its safety. CASA, as Australia's national airworthiness authority, must then assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed by the AD include ensuring that the relevant aircraft comply with the safety measures specified by CASA. This involves the aircraft operators and owners taking corrective actions as outlined in the AD, such as inspections, repairs, or modifications. Failure to comply with the AD can result in serious safety risks, including potential grounding of the aircraft. The AD also includes the requirement for CASA to monitor compliance and take enforcement actions against non-compliant aircraft operators.
There are significant consequences for non-compliance with an airworthiness directive. Under the Civil Aviation Act 1988, violations can result in both civil and criminal penalties. Civil penalties can include fines, and in severe cases, criminal penalties may be imposed. For instance, under section 422 of the Act, an individual can be fined up to $21,000 for non-compliance with an AD. Additionally, CASA has the authority to take enforcement actions such as grounding non-compliant aircraft, which can severely impact the operations of the aircraft owner or operator. Therefore, compliance with ADs is not just a legal requirement but a critical aspect of ensuring the safety of air navigation in Australia.
