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 Japan Civil Aviation Bureau has issued AD TCD-7111-2007 affecting Kawasaki BK117 C2 helicopters. Japan is the State of Design for this helicopter. CASA has assessed this AD and has issued Australian AD/JBK 117/27, which will become effective on 13 March 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, Systems 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 establish a comprehensive legal framework for civil aviation in Australia, aiming to ensure the safety, efficiency, and orderly development of civil aviation. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation, thereby facilitating the oversight and regulation of airworthiness. The Civil Aviation Safety Regulations 1998, under this Act, specifically allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products. These ADs are legislative instruments subject to disallowance and are a fundamental part of maintaining the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The issuance of ADs is critical in fulfilling Australia’s obligations under international agreements and ensuring that the nation’s aviation safety standards are consistently upheld.
Scope and Application
The Civil Aviation Safety Regulations 1998, as an extension of the Civil Aviation Act 1988, establish the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory mechanism ensures the safety and continuing airworthiness of aircraft registered in Australia, aligning with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs, including Australian AD/JBK 117/27, are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901. These directives apply to entities such as aircraft manufacturers, operators, and owners within Australia, ensuring compliance with both national and international safety standards. The jurisdictional reach of these regulations is national, with CASA, as the national airworthiness authority, mandated to issue ADs in response to directives from the State of Design, in this case, Japan for the Kawasaki BK117 C2 helicopters. This legislative framework does not require public consultation or a Regulatory Impact Statement for ADs, reflecting their technical nature and the reliance on international safety standards.
Key Provisions
The Civil Aviation Act 1988 (sections 98) and the Civil Aviation Safety Regulations 1998 (section 39.001) provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments and are issued to ensure the safety of air navigation. Specifically, section 39.001(5) of the Civil Aviation Safety Regulations 1998 confirms that ADs are disallowable instruments under the Acts Interpretation Act 1901. The issuing of ADs is part of Australia's commitment to the Convention on International Civil Aviation, with Annex 8 stipulating the State of Design's responsibility for the continuing airworthiness of an aircraft type and the State of Registry's duty to ensure the airworthiness of individual aircraft.
The obligations imposed by these provisions require CASA to evaluate any ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs. This ensures that Australian registered aircraft meet international safety standards. For example, the Japan Civil Aviation Bureau issued AD TCD-7111-2007 concerning Kawasaki BK117 C2 helicopters, to which CASA responded by issuing Australian AD/JBK 117/27. Given the international nature of these directives and the regulatory framework under which they operate, no public consultation is required, and a Regulatory Impact Statement is not mandated.
The failure to comply with an AD can have serious legal and safety consequences. The Act does not explicitly outline the penalties for non-compliance with ADs; however, non-compliance with aviation safety regulations generally can result in substantial civil or criminal penalties. Such penalties may include fines and imprisonment, depending on the severity of the breach and the specific provisions of other relevant legislation. CASA has the authority to enforce compliance and may take action against those who fail to adhere to the mandated safety requirements.
