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 78-09-09 affecting Rolls Royce AL 501 series engines. The United States is the State of Design for this engine series. CASA has assessed this AD and has issued Australian AD/AL501/5, which will become effective on 8 June 2006.
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, New Technologies and Systems, 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 legal framework for civil aviation in Australia, addressing gaps and problems in the regulation of aircraft safety and air navigation. This Act empowers the Governor-General to make regulations necessary for ensuring the safety of air navigation, thereby enabling the Civil Aviation Safety Authority (CASA) to implement measures that safeguard the public from aviation risks. As part of this framework, the Civil Aviation Safety Regulations 1998 allow CASA to issue airworthiness directives, which are legislative instruments designed to maintain the airworthiness of aircraft. This legislative approach is consistent with Australia's obligations under the Convention on International Civil Aviation, ensuring alignment with international standards and practices. The authority to issue such directives is exercised by CASA in response to directives issued by the State of Design or based on international safety requirements, as exemplified by the issuance of Australian AD/AL501/5 in response to a United States Federal Aviation Administration directive concerning Rolls Royce AL 501 series engines. This process underscores the importance of international cooperation in maintaining global aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. This authority is exercised under section 98 of the Civil Aviation Act 1988, with the overarching aim of ensuring the safety of air navigation. These ADs, which serve as legislative instruments as per the Acts Interpretation Act 1901, are issued in response to obligations under international agreements such as Annex 8 to the Convention on International Civil Aviation. The ADs are critical for the continuing airworthiness of aircraft, with the State of Design having primary responsibility for the airworthiness of an aircraft type and the State of Registry tasked with ensuring the airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, is mandated to issue corresponding Australian ADs when required by the State of Design, such as in the case of AD/AL501/5 issued in response to the United States FAA's AD 78-09-09 concerning Rolls Royce AL 501 series engines. Given the international nature and technical basis of such directives, they do not require public consultation or a Regulatory Impact Statement, and are made by authorised CASA personnel in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides a framework for the regulation of airworthiness in Australia. Specifically, section 98 of the Act empowers the Governor-General to create regulations for the safety of air navigation, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as crucial tools in maintaining the continuing airworthiness of aircraft and are recognised under Annex 8 of the Convention on International Civil Aviation. The issuing of ADs is grounded in the responsibility of the State of Design to provide necessary information for maintaining airworthiness, and the State of Registry’s obligation to implement these requirements.
Under the Civil Aviation Safety Regulations 1998, the obligations imposed on CASA include assessing any airworthiness directives issued by the State of Design that affect aircraft registered in Australia. If deemed necessary, CASA must issue corresponding Australian ADs to enforce the same safety standards. This ensures that aircraft registered in Australia meet international safety standards and maintain airworthiness. The regulations mandate that CASA, as Australia's national airworthiness authority, must act swiftly to incorporate international ADs into domestic regulations, thereby ensuring consistency with global safety standards.
Failure to comply with an airworthiness directive can lead to significant legal consequences. The Act and Regulations impose strict requirements on aircraft operators and owners to adhere to ADs. Non-compliance can result in severe penalties, including fines and potential criminal charges. The maximum penalties for breaches of airworthiness regulations are substantial, reflecting the critical importance of maintaining air safety. For instance, under the Civil Aviation Act 1988, operators found in violation of an AD may face fines of up to $100,000 for individual offences and additional penalties for corporate entities. Furthermore, persistent non-compliance may lead to more severe criminal charges, including imprisonment, highlighting the seriousness with which the law treats breaches of airworthiness directives.
