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.
State of Design ADs issued on or after 1 October 2009 are defined as ADs per Civil Aviation Safety Regulations Part 39.001A.
CASA issued AD/BR700/8 affecting Rolls Royce Germany BR700 series turbine engines. The EASA issued AD 2009-0273-E on 21 December 2009 which supersedes the requirements of AD/BR700/8 and as such this AD has been cancelled. The EASA acts on behalf of Germany which is the state of design for these engines. The cancellation will become effective on 22 January 2010.
No consultation with the Australian public has taken place on this AD cancellation. 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, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing gaps in previous aviation laws and ensuring the safety and efficiency of air navigation. Under the authority conferred by this Act, the Governor-General can make regulations aimed at maintaining and enhancing the safety of air navigation. One such regulation, detailed in the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring compliance with safety standards. ADs serve as critical tools for maintaining the continuing airworthiness of aircraft, with CASA acting as the national airworthiness authority responsible for assessing and implementing directives issued by the State of Design or other regulatory bodies. The ADs are legislative instruments subject to disallowance, and their issuance is guided by international standards set out in Annex 8 to the Convention on International Civil Aviation. The AD cancellation process, such as the recent cancellation of AD/BR700/8, reflects ongoing efforts to harmonise international standards and ensure the highest levels of aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are integral to maintaining the continuing airworthiness of aircraft and are applicable to all entities and persons involved in the operation, maintenance, and design of aircraft registered in Australia. This includes aircraft manufacturers, operators, and maintenance providers. The geographic reach of these regulations is national, applying uniformly across Australia, and they are consistent with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of aircraft types and must supply necessary information to the States of Registry, which in turn, must implement the ADs to ensure compliance. Notably, the ADs are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. Any ADs issued by CASA or other regulatory authorities, such as the European Union Aviation Safety Agency (EASA), must align with the overarching principles of ensuring aviation safety and operational integrity. The application of these regulations extends to all aircraft within the Australian Register, with no exclusions specified, ensuring a uniform approach to airworthiness across the industry.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations aimed at enhancing air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework is further defined by subregulation 39.001(5), which classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, thus, as legislative instruments according to section 6 of the Legislative Instruments Act 2003. These airworthiness directives serve as a critical mechanism for maintaining the safety standards of aircraft, ensuring they meet the continuing airworthiness criteria outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by this Act and its regulations are significant. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to ensure compliance with safety standards. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to enforce these standards. CASA, as Australia's national airworthiness authority, is tasked with assessing information from State of Design ADs and issuing Australian ADs when necessary. This dual responsibility ensures that all aircraft within Australia’s jurisdiction maintain the highest safety standards. The specific AD/BR700/8, issued by CASA for Rolls Royce Germany BR700 series turbine engines, exemplifies this process where CASA aligns Australian requirements with international standards set by the European Aviation Safety Agency (EASA).
Failure to comply with the requirements set out in airworthiness directives can result in serious legal consequences. The Act does not explicitly detail the penalties for non-compliance with ADs, but general aviation regulations often include provisions for fines, imprisonment, or both for serious breaches. For example, under the Crimes Act 1914, individuals or entities found guilty of endangering the safety of an aircraft could face imprisonment for up to five years or fines of up to $210,000, or both. The severity of these penalties underscores the importance of adhering to airworthiness directives to protect public safety. In this specific case, the cancellation of AD/BR700/8 by EASA, which supersedes CASA's previous directive, highlights the need for continuous compliance with the latest safety standards issued by relevant authorities.
