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 369/32 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/32. The cancellation will become effective on 4 June 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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, with the Civil Aviation Safety Regulations 1998 being a key component. These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments under the Legislative Instruments Act 2003, reflecting their regulatory nature. In line with international standards set by Annex 8 to the Convention on International Civil Aviation, the State of Design of an aircraft type is tasked with ensuring the aircraft's continuing airworthiness, while the State of Registry, in this case CASA, is responsible for enforcing these standards domestically. Consequently, CASA reviews and, if necessary, issues Australian ADs to enforce the requirements set by the State of Design. In this instance, CASA has cancelled Australian AD/HU 369/32 for McDonnell Douglas (Hughes) 369 series Helicopters, effective from 4 June 2009, as the unsafe condition previously identified no longer exists.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are integral to ensuring the safety of air navigation and are considered legislative instruments under the Legislative Instruments Act 2003. The State of Design, responsible for the continuing airworthiness of an aircraft type, issues ADs, which the State of Registry must then adopt. In Australia, CASA, as the national airworthiness authority, evaluates the ADs issued by the State of Design and issues corresponding Australian ADs when necessary. This process ensures compliance with international standards, particularly under Annex 8 of the Convention on International Civil Aviation. The cancellation of AD/HU 369/32 for McDonnell Douglas (Hughes) 369 series Helicopters exemplifies this procedure, reflecting CASA's commitment to maintaining airworthiness standards without necessitating public consultation or a Regulatory Impact Statement. The AD cancellation aligns with Australia’s obligations under the Convention and was made by the Manager, Airframe and Structures, within CASA’s Airworthiness Engineering Group, as per the Act’s provisions.
Key Provisions
The Civil Aviation Act 1988, as amended, allows the Governor-General to issue regulations for the safety of air navigation (section 98). Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies these ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thus making them legislative instruments according to section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are integral to ensuring the continuing airworthiness of aircraft, as per Annex 8 of the Convention on International Civil Aviation. The State of Design holds the primary responsibility for maintaining the airworthiness of an aircraft type and must supply necessary information to ensure compliance with safety standards. The State of Registry, which is responsible for the individual aircraft, must then develop or adopt requisite measures to ensure ongoing airworthiness. When a State of Design issues an AD, CASA, acting as Australia's national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the State of Design's requirements.
An example of this process is evident in AD/HU 369/32, which affected McDonnell Douglas (Hughes) 369 series Helicopters. After assessment, CASA has cancelled this Australian AD, as the unsafe condition it targeted no longer exists. This cancellation will take effect on 4 June 2009, and no replacement AD is required. The cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation, which obviates the need for public consultation on this matter. Additionally, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement. The AD was issued by the Manager, Airframe and Structures, in the Airworthiness Engineering Group on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of legal consequences, any breach of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998 can lead to various penalties. Offences may result in both civil and criminal consequences, depending on the nature and severity of the breach. Civil penalties can include fines, while criminal penalties may encompass imprisonment. The maximum penalties for specific violations are detailed within the respective sections of the Act and Regulations, reflecting the serious implications of non-compliance with aviation safety standards.
