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-2008-04 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 407/9, Amendment 3, which will become effective on 15 February 2008. This AD cancels and replaces the previous issue.
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 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing the need for stringent safety standards and the coordination of aviation activities within the country. The Act authorises the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) aimed at ensuring the continuing airworthiness of aircraft and aeronautical products. These directives are legislative instruments under the Legislative Instruments Act 2003, designed to align with international standards as set out in Annex 8 to the Convention on International Civil Aviation. The State of Design, such as Canada in the case of Bell 407 model helicopters, has the responsibility to provide necessary information to maintain airworthiness, which CASA must then assess and, if necessary, mandate through Australian ADs. The issuance of ADs is driven by international obligations and the requirement to maintain safety standards, and thus does not require public consultation or a Regulatory Impact Statement. This AD was made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the Act’s provisions.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, with the aim of ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These directives are legislative instruments subject to disallowance and are designed to maintain the continuing airworthiness of aircraft as per international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for the airworthiness of an aircraft type and must provide necessary information to States of Registry, which in turn, must ensure the airworthiness of individual aircraft registered within their jurisdiction. In Australia, CASA, as the national airworthiness authority, assesses and issues ADs in response to those issued by States of Design, ensuring compliance with international obligations and domestic safety standards. This process does not require public consultation or a Regulatory Impact Statement, as it is governed by the specific mandates of the Convention on International Civil Aviation and is a routine part of international civil aviation safety practices.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These ADs, detailed in subregulation 39.001(5), are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments as per section 6 of the Legislative Instruments Act 2003. The ADs aim to ensure the continuing airworthiness of aircraft types and products.
The obligations under this legislation require CASA to assess any ADs issued by the State of Design, which is the State responsible for the aircraft type. For instance, Transport Canada issued an AD (CF-2008-04) for Bell 407 model helicopters, which CASA evaluated and subsequently issued as Australian AD/BELL 407/9, Amendment 3. The State of Registry, in this case, CASA, must ensure that these ADs are adopted and enforced within Australia. The State of Design has the responsibility to provide necessary information to maintain the airworthiness of their aircraft types, and the State of Registry must implement the necessary requirements to ensure compliance.
The legislation imposes significant obligations on the parties involved. CASA, as the national airworthiness authority, must rigorously assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. Operators of the affected aircraft must comply with these ADs to maintain the airworthiness of their aircraft. Failure to comply with these ADs can result in serious safety implications and potential legal consequences.
Breach of these ADs can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with ADs is an offence, which can result in significant penalties. For example, CASA has the authority to issue infringement notices for minor breaches, which can lead to fines. More serious breaches may result in prosecution, with potential penalties including substantial fines and imprisonment. Additionally, operators failing to comply with ADs may face suspension or revocation of their airworthiness certificates, effectively grounding their aircraft until compliance is achieved. These stringent measures underscore the importance of adhering to ADs to maintain the highest safety standards in civil aviation.
