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 2006-23-14 affecting Air Tractor AT 800 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT 800/10, which will become effective on 18 January 2007.
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, Airframes 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 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, addressing various aspects of aviation safety, air navigation, and the oversight of aviation operations. The Act establishes the Civil Aviation Safety Authority (CASA) as the national airworthiness authority and grants it the power to issue airworthiness directives (ADs) to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the procedures for issuing these directives, specifying that they are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. This legislative framework was introduced to align Australia's aviation safety practices with international standards set by the International Civil Aviation Organization (ICAO). The policy objective is to ensure the continuing airworthiness of aircraft and aeronautical products by requiring States of Design and Registry to cooperate in disseminating and implementing safety measures. The ADs are issued by CASA following the assessment of information provided by the relevant State of Design, thereby fulfilling Australia's obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, with these directives being a legislative instrument as per the Legislative Instruments Act 2003. These ADs are integral to ensuring the continuing airworthiness of aircraft, a responsibility primarily vested in the State of Registry, in accordance with Annex 8 to the Convention on International Civil Aviation. When the State of Design, such as the US Federal Aviation Administration (FAA) in the case of Air Tractor AT 800 model aircraft, issues an AD, CASA, as Australia's national airworthiness authority, must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design. In this instance, CASA has issued Australian AD/AT 800/10, effective from 18 January 2007, in response to FAA's AD 2006-23-14. Given the international obligations and the direct response to a State of Design AD, no public consultation has been conducted, and the Office of Regulatory Review has determined that ADs do not necessitate a Regulatory Impact Statement. This AD was made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office at CASA, under the authority of subsection 84A(2) of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as regulatory mandates aimed at ensuring the safety and airworthiness of aircraft registered in Australia. Each AD is a legislative instrument, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and is regulated by the Legislative Instruments Act 2003. Section 98 of the Civil Aviation Act 1988 supports the issuance of these regulations, emphasising the need for safety in air navigation.
The obligations imposed by the ADs are comprehensive and focus on maintaining the highest safety standards in the aviation industry. CASA, as Australia's national airworthiness authority, must rigorously assess information provided by the State of Design—the country where the aircraft was originally designed. For instance, the United States, as the State of Design for the Air Tractor AT 800 model, issued AD 2006-23-14. CASA, after evaluating this directive, issued Australian AD/AT 800/10, which mandates specific requirements to be followed by operators of the AT 800 model in Australia. The State of Registry, which is Australia in this context, is also responsible for ensuring the continuing airworthiness of the aircraft registered within its jurisdiction. This includes adopting or developing requirements that align with the ADs issued by the State of Design.
In terms of compliance and enforcement, breaches of ADs can lead to significant legal consequences. Failure to comply with an AD can result in both civil and criminal penalties. Civil penalties may include fines, and in severe cases, criminal penalties can be imposed, which may include imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. CASA has the authority to take action against non-compliant operators, including the grounding of aircraft until compliance is achieved. Given the serious implications of non-compliance, it is crucial for all stakeholders in the aviation industry to adhere to the ADs strictly.
