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 2009-07-11 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/235, Amendment 1, which will become effective on 4 June 2009. 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, Airframes & Structures in the Airworthiness Engineering Group, 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 ensuring the safety and efficiency of civil aviation in Australia. One of its primary objectives is to enable the regulation of air navigation safety, including the issuance of airworthiness directives (ADs) as mandated by the Civil Aviation Safety Regulations 1998. The Act empowers the Governor-General to make regulations, such as ADs, that align with the safety interests of air navigation. Pursuant to this authority, the Civil Aviation Safety Authority (CASA) issues ADs for specific types of aircraft or aeronautical products to maintain and enhance airworthiness standards. The issuing of these directives is a critical component of Australia's commitment to international civil aviation standards, particularly under Annex 8 of the Convention on International Civil Aviation, which places responsibility on the State of Design to ensure continuing airworthiness and the dissemination of necessary information to States of Registry. CASA, as Australia's national airworthiness authority, evaluates and, when necessary, issues Australian ADs to enforce these requirements, ensuring compliance with both domestic and international safety protocols.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) within Australia. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products under regulation 39.001. This regulatory process is integral to maintaining the safety standards of aircraft registered in Australia and ensuring compliance with international aviation safety norms as stipulated in Annex 8 of the Convention on International Civil Aviation. The ADs are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901, as outlined in section 6 of the Legislative Instruments Act 2003. The issuance of ADs by CASA, Australia’s national airworthiness authority, is typically in response to directives issued by the State of Design or as a result of Australia's international obligations. These directives are designed to address specific safety issues identified by the relevant State of Design and ensure the continuing airworthiness of aircraft types registered in Australia. The ADs issued by CASA are effective in mandating compliance with the safety requirements stipulated by the originating State of Design.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Under subregulation 39.001(5), ADs are recognised as disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The ADs are integral to ensuring the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which in this case is the United States for Boeing B737 model aircraft, bears the responsibility for the ongoing airworthiness of the aircraft type and must furnish necessary information to the States of Registry. For Australia, the State of Registry, CASA assumes the role of the national airworthiness authority. When a State of Design issues an AD, CASA is mandated to evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the requirements set by the State of Design.
Compliance with these ADs is mandatory for all parties involved. CASA, as the national airworthiness authority, must rigorously assess the information provided by the State of Design and issue appropriate ADs to ensure the continuing airworthiness of aircraft registered in Australia. Operators of affected aircraft must adhere to the requirements stipulated in the ADs to maintain compliance with airworthiness standards. Failure to comply with an AD may result in significant legal and operational repercussions, including potential grounding of the aircraft until compliance is achieved.
The regulatory framework also encompasses provisions for sanctions in cases of non-compliance. Breaches of ADs may result in severe consequences, both civil and criminal. Civil penalties can include fines, while criminal penalties may include imprisonment, reflecting the serious nature of ensuring air navigation safety. The specific penalties depend on the severity of the breach and the discretion of the court, but the overarching intent is to enforce strict compliance to safeguard public safety.
