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/HU 269/105 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/105. The cancellation will become effective on 7 May 2009. 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, Airframe and 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 is a foundational piece of legislation enacted by the Australian Parliament to regulate civil aviation in the country, with the primary objective of ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations for the purposes of the Act, focusing on maintaining the highest safety standards within air navigation. One significant aspect of this legislation is its enabling of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, thereby ensuring compliance with international standards set forth by the Convention on International Civil Aviation. These directives serve as critical tools for maintaining the continuing airworthiness of aircraft, a responsibility shared between the States of Design and Registry. The Act and its associated regulations aim to harmonise Australia's approach to air safety with international practices, thereby protecting both domestic and international airspace.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs are legislative instruments, as stipulated by the Legislative Instruments Act 2003, and serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft types. The responsibility for issuing ADs falls on the State of Design, which must provide necessary information to the States of Registry, including Australia, to ensure the safety standards are met. CASA, as Australia's national airworthiness authority, assesses this information and, if necessary, issues corresponding Australian ADs. In the case of Schweizer (Hughes) 269 series Helicopters, CASA has assessed and subsequently cancelled the Australian AD/HU 269/105 due to the resolution of the unsafe condition identified, with the cancellation becoming effective on 7 May 2009. Given the international obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required for this AD cancellation. The AD was issued by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the provisions of the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the issuance of airworthiness directives (ADs) in Australia, which are critical for maintaining the safety and airworthiness of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations to ensure the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. It is important to note that these ADs are considered legislative instruments, as stipulated in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, which aligns with section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA to closely monitor and respond to ADs issued by the State of Design of an aircraft type, ensuring that any identified safety issues are appropriately addressed within the Australian context. This responsibility includes assessing the information provided by the State of Design and, if necessary, issuing an Australian AD to enforce the required safety measures. The State of Registry is also tasked with ensuring the continuing airworthiness of individual aircraft and must establish or adopt the necessary requirements to fulfil this duty. The State of Design’s obligation to provide necessary information for the continuing airworthiness of aircraft types is paramount, as stipulated in Annex 8 to the Convention on International Civil Aviation.
Failure to comply with the requirements set out in ADs can result in significant legal consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences or penalties for non-compliance with ADs. However, general provisions within the Act provide for enforcement actions, including fines and imprisonment, for breaches of aviation safety regulations. The severity of the penalties can depend on the nature and extent of the non-compliance, with potential maximum penalties for serious offences reaching significant financial and custodial terms as outlined in other sections of the Act. Adhering to ADs is crucial for maintaining the safety standards of air navigation, and any failure to comply can lead to enforcement actions by CASA.
