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 Civil Aviation Safety Authority or its predecessors issued AD/BELL 206/30 affecting Bell 206A model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, 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, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation and provide a comprehensive regulatory framework governing civil aviation in Australia. The Act allows the Governor-General to make regulations for the purposes of the Act, including the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that mandate requirements to ensure the continuing airworthiness of aircraft types registered in Australia. The Civil Aviation Safety Authority (CASA), as the national airworthiness authority, is responsible for assessing airworthiness information provided by the State of Design and issuing Australian ADs as necessary. Recently, CASA issued an airworthiness directive for the Bell 206A model aircraft, which has since been cancelled due to the resolution of the unsafe condition identified. This cancellation aligns with Australia's obligations under the Convention on International Civil Aviation, and no consultation or Regulatory Impact Statement was required. The cancellation will become effective on 23 October 2008, and no replacement AD is necessary.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, thereby ensuring the continuing airworthiness of these aircraft in line with safety standards set forth in the Civil Aviation Act 1988. The issuance of these ADs is integral to fulfilling Australia’s obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design bears the responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry, including Australia. CASA, acting as the national airworthiness authority, assesses the information provided by the State of Design and, when necessary, issues Australian ADs to enforce the required safety measures. This process ensures that the safety standards are uniformly applied across the Australian aviation sector. Notably, the ADs are legislative instruments, subject to disallowance and the scrutiny of the Legislative Instruments Act 2003, but do not require a Regulatory Impact Statement or public consultation as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety and continuing airworthiness of aircraft in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations to protect the safety of air navigation, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and are governed under the Legislative Instruments Act 2003.
Under these provisions, CASA has issued an AD for the Bell 206A model aircraft, which has now been cancelled. This action aligns with Australia’s obligations under Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type. When such an AD is issued by the State of Design, CASA must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements stipulated by the State of Design. In this case, CASA assessed the AD and decided that it was no longer necessary due to the resolution of the unsafe condition identified, leading to the cancellation of AD/BELL 206/30.
Entities governed by these regulations must adhere to the requirements set forth by CASA. This includes compliance with ADs issued by CASA, ensuring that any identified safety issues are addressed promptly. Specifically, the State of Registry for an aircraft must implement the requirements of any AD to maintain the continuing airworthiness of the aircraft. This responsibility extends to ensuring that all modifications, repairs, and inspections are performed in accordance with the ADs.
Failure to comply with the ADs may result in significant consequences. Although the Civil Aviation Safety Regulations 1998 do not specify particular offences or penalties for non-compliance with ADs, the overarching Civil Aviation Act 1988 and other related legislation provide a framework for enforcement. Non-compliance can lead to enforcement actions, including fines and potential criminal charges for serious breaches that endanger safety. The severity of the penalties depends on the nature and impact of the non-compliance, with maximum penalties for breaches that endanger safety potentially leading to substantial financial penalties or imprisonment.
