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 German LBA has issued AD D-2008-178 affecting Eurocopter Deutschland EC135 and EC635 model helicopters. Germany is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/EC 135/16, which will become effective on 30 May 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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to address issues surrounding the safety of air navigation, empowers the Governor-General to make regulations under section 98 for the Act's purposes and the interests of air navigation safety. This Act is administered by the Parliament of Australia and aims to ensure the safety and efficiency of civil aviation. One of the key instruments under this Act is the Civil Aviation Safety Regulations 1998, which include the issuance of airworthiness directives (ADs) under regulation 39.001. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, are used to mandate requirements for the continuing airworthiness of aircraft types. The Civil Aviation (Administrative Arrangements) Order 2009 designates the Civil Aviation Safety Authority (CASA) as the national airworthiness authority responsible for assessing and issuing ADs in line with international obligations under the Convention on International Civil Aviation. This process ensures that Australia meets its international commitments and maintains the safety standards required for aircraft registered in the country.
Scope and Application
The Civil Aviation Act 1988 and its subsidiary regulations, particularly the Civil Aviation Safety Regulations 1998, govern the issuance of airworthiness directives (ADs) within Australia, with the objective of ensuring the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General can enact regulations deemed necessary for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory framework applies to entities such as aircraft manufacturers, operators, and maintenance providers, ensuring they comply with airworthiness standards. Geographically, the Act and its regulations have a national reach, applying across Australia. ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and are issued in accordance with international standards, including those set by the International Civil Aviation Organization (ICAO). Notably, these directives do not require public consultation or a Regulatory Impact Statement, as they are developed in response to international obligations and directives issued by the aircraft's State of Design. The ADs are issued by CASA, Australia's national airworthiness authority, to mandate the requirements specified by the State of Design, thereby maintaining the continuing airworthiness of aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations for the Act's purposes and in the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 (regulation 39.001) further specify that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives, defined in subregulation 39.001(5) as disallowable instruments, are legislative instruments under the Legislative Instruments Act 2003. In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design has primary responsibility for the continuing airworthiness of aircraft types and must provide necessary information to ensure this airworthiness is maintained by appropriate States of Registry. ADs are the primary means of conveying continuing airworthiness information, issued by most International Civil Aviation Organization (ICAO) Contracting States.
The obligations imposed by these provisions include the responsibility of the State of Design to issue ADs for aircraft types under its purview, ensuring they are aligned with safety standards. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of registered aircraft. CASA, as Australia's national airworthiness authority, is required to assess information from foreign ADs and issue corresponding Australian ADs if necessary. This process ensures that Australian-registered aircraft meet international safety standards.
Failure to comply with airworthiness directives can result in serious legal consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can lead to significant penalties. For instance, if an aircraft is operated in a manner that does not conform to an airworthiness directive, the operator may face criminal charges. The Act also provides for civil penalties, including fines and potential grounding of the aircraft. Additionally, CASA has the authority to take enforcement actions against non-compliant operators, which can include suspending or revoking their operating certificates.
In summary, the ADs issued under the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 are crucial for maintaining airworthiness and safety in aviation. They impose clear obligations on States of Design and Registry, and CASA, to ensure that aircraft meet international safety standards. Non-compliance with these directives can result in significant criminal and civil penalties, underscoring the importance of adherence to these regulations.
