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 Brazilian ANAC has issued AD 2008-01-03 affecting Embraer ERJ-170 model aircraft. Brazil is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ERJ-170/14, which will become effective on 10 April 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 provide a comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to create regulations that contribute to the safety of air navigation, with one significant example being the Civil Aviation Safety Regulations 1998. These regulations, among other provisions, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This authority is exercised under the auspices of maintaining the continuing airworthiness of aircraft as mandated by international standards set forth in the Convention on International Civil Aviation. The ADs are critical in ensuring that aircraft remain safe and airworthy, aligning with the overarching policy objective of enhancing aviation safety. The process of issuing an AD, such as the recent AD/ERJ-170/14 concerning Embraer ERJ-170 model aircraft, is driven by the obligations under the Convention and the assessments conducted by CASA, reflecting a collaborative international approach to aviation safety.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the safety and airworthiness of aircraft and aeronautical products within Australia. The Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs, being legislative instruments, are subject to disallowance and are intended to maintain and ensure the continuing airworthiness of aircraft. The application of ADs is comprehensive, covering all aircraft and aeronautical products registered in Australia, and extends to ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is responsible for assessing and issuing these directives, which mandate specific requirements to be met by aircraft operators to maintain airworthiness. The process involves evaluating ADs issued by the State of Design and, if deemed necessary, issuing corresponding Australian ADs. Exemptions or exclusions from these regulations are not explicitly stated in the provided text, but the international obligations under the Convention on International Civil Aviation and the jurisdictional scope of CASA’s authority are clearly defined.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay out the framework for the issue of airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations that promote the safety of air navigation, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Section 39.001(5) further clarifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901 and is considered a legislative instrument as per the Legislative Instruments Act 2003. This means that ADs are formal regulatory instruments that have the force of law and are subject to disallowance by Parliament.
The obligations imposed by these provisions fall primarily on CASA as Australia’s national airworthiness authority. When the State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate the directive. If deemed necessary, CASA must issue an Australian AD to ensure the continuing airworthiness of the aircraft. This involves a rigorous assessment process to determine whether the requirements of the State of Design are appropriate for Australian conditions. CASA's role is crucial in maintaining safety standards and ensuring that Australian aircraft meet international airworthiness requirements.
Failure to comply with ADs can lead to serious consequences. Civil aviation law imposes strict penalties for non-compliance, which can include fines and imprisonment. Under the Civil Aviation Act 1988, any person who contravenes an AD can be fined up to $222,200 for an individual offence and up to $1,111,000 for a corporate offence. Additionally, CASA has the authority to take enforcement actions, such as grounding non-compliant aircraft, which can significantly impact airline operations and passenger safety. These stringent penalties underscore the importance of adhering to ADs to maintain the highest safety standards in civil aviation.
