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.
Transport Canada has issued AD CF-2009-10 affecting Bell 407 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 407/32, which will become effective on 13 March 2009.
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, enacted by the Australian Parliament, aims to regulate civil aviation to ensure safety and efficiency within Australia. It provides the legislative framework for the Civil Aviation Safety Authority (CASA) to manage and enforce aviation safety standards. One of the significant mechanisms under this Act is the issuance of airworthiness directives (ADs), which are regulatory instruments made under the authority conferred by section 98 of the Act. These ADs are issued to ensure that aircraft and aeronautical products maintain their airworthiness according to safety standards. The Civil Aviation Safety Regulations 1998 further detail the process and criteria for issuing ADs, ensuring they are aligned with international standards set by the International Civil Aviation Organization (ICAO). The policy objective of these regulations is to uphold the highest safety standards in the aviation industry, thereby protecting the public and ensuring efficient air navigation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, encompasses a broad spectrum of aviation safety regulations, including the issuance of airworthiness directives (ADs). These ADs apply to all aircraft and aeronautical products registered in Australia, ensuring adherence to safety standards established under both domestic and international regulations. The ADs are legislative instruments made under the authority of the Governor-General and managed by the Civil Aviation Safety Authority (CASA). These directives are issued in response to identified safety issues or deficiencies in specific aircraft types, and are essential for maintaining the continuing airworthiness of aircraft. They are mandated by the Convention on International Civil Aviation, which obliges the State of Design to provide necessary information to ensure airworthiness, with the State of Registry, in this case CASA, responsible for issuing corresponding ADs. The ADs do not necessitate public consultation or a Regulatory Impact Statement, reflecting their urgent and technical nature, and are issued by CASA to ensure compliance with international safety standards.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003 and are disallowable instruments under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Act and regulations primarily rest with CASA as the national airworthiness authority. When the State of Design issues an AD concerning a type of aircraft registered in Australia, CASA must evaluate the provided information and, if necessary, issue an Australian AD to enforce the State of Design's requirements. For instance, Transport Canada has issued AD CF-2009-10 concerning Bell 407 model helicopters, and CASA has responded by issuing Australian AD/BELL 407/32, effective from 13 March 2009. This reflects CASA’s duty to ensure the continuing airworthiness of aircraft registered in Australia, in alignment with international standards set forth in Annex 8 of the Convention on International Civil Aviation.
The ADs must be issued without public consultation because they arise from Australia's international obligations and are direct responses to ADs from the relevant State of Design. Furthermore, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The issuance of these directives follows a formal process, with the Manager, Airframes & Structures in the Airworthiness Engineering Group making the AD on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Failure to comply with an airworthiness directive can lead to severe consequences. Both civil and criminal penalties can be imposed for non-compliance. Under the Civil Aviation Act 1988, non-compliance with ADs can result in civil penalties, including fines, and may also lead to criminal charges if the non-compliance results in significant harm or endangerment. The exact penalties are detailed in the Civil Aviation Regulations and can vary based on the severity and nature of the non-compliance. These measures ensure that all parties adhere to the stringent safety standards required for the operation of aircraft within Australia.
