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.
CASA issued AD/L.40/8 affecting Meta Sokol L.40 model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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. The Act addresses the need for a consistent and robust system to ensure the safety and efficiency of civil aviation. Enacted by the Parliament of Australia, the Act's policy objective is to maintain and enhance the safety of air navigation, which is achieved through the regulation of aircraft and aeronautical products. The Act empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives to ensure that aircraft and aeronautical products meet safety standards. This regulatory power is exercised under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows CASA to mandate specific requirements for the continuing airworthiness of aircraft types registered in Australia. The cancellation of an existing airworthiness directive, such as AD/L.40/8 for the Meta Sokol L.40 model aircraft, is conducted by CASA to address outdated or resolved safety concerns, thereby reducing regulatory burden without the need for public consultation.
Scope and Application
The Civil Aviation Act 1988, specifically through regulation 39.001 of the Civil Aviation Safety Regulations 1998, 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 that serve as a means for ensuring the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The issuing of ADs is a responsibility of the State of Design, which must provide necessary information to States of Registry to maintain airworthiness. CASA, as Australia’s national airworthiness authority, is required to assess this information and issue Australian ADs if appropriate. The cancellation of an existing AD, such as AD/L.40/8 for Meta Sokol L.40 model aircraft, is conducted by CASA and, in this case, does not necessitate public consultation or a Regulatory Impact Statement as it reduces the regulatory burden. This cancellation was carried out by the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988, under section 98, allows the Governor-General to make regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various kinds of aircraft and aeronautical products. These ADs are legislative instruments, as specified in subregulation 39.001(5) and in accordance with section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs are a critical component of ensuring the continuing airworthiness of aircraft types as stipulated under Annex 8 of the Convention on International Civil Aviation, where the State of Design holds responsibility for providing necessary information to the States of Registry.
In terms of obligations, the State of Design must furnish information essential for the continuing airworthiness of an aircraft type to the appropriate States of Registry. The State of Registry, in turn, is tasked with developing or adopting requirements to ensure the aircraft's continuing airworthiness. When an AD is issued by a State of Design against a type of aircraft registered in Australia, CASA must evaluate the information and, if necessary, issue an Australian AD that mandates the requirements set forth by the State of Design. This ensures that the safety standards are consistently applied across all aircraft types operating within Australia.
The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 do not specify any direct civil or criminal penalties for non-compliance with ADs. However, non-compliance with ADs can result in severe consequences, including potential grounding of the aircraft, which can have significant financial implications for the operator. Moreover, CASA has the authority to take enforcement actions against operators who fail to comply with ADs, which could include fines or other regulatory measures.
CASA issued AD/L.40/8 affecting Meta Sokol L.40 model aircraft in 1972, and has now decided to cancel this AD, effective 17 January 2008. This decision was made following a review, and no replacement AD is necessary as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1. The cancellation of the AD was determined to reduce the regulatory burden, and no consultation with the Australian public was required. The Office of Best Practice Regulation has also concluded that ADs do not necessitate a Regulatory Impact Statement. The AD cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
