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 US FAA has issued AD 2008-05-17 affecting MD Helicopters model 600N helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/HU 369/108, Amendment 2, which will become effective on 5 June 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, enacted by the Australian Parliament, provides the legal framework for ensuring the safety and efficiency of civil aviation within the country. The Act empowers the Governor-General to make regulations aimed at enhancing air navigation safety. One such regulation, detailed in the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This mechanism is essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design the responsibility for ensuring the airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, is tasked with assessing and, if necessary, issuing Australian ADs to enforce the requirements set by the State of Design. This process ensures compliance with international standards and obligations while safeguarding the safety of Australian airspace.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 establish a comprehensive framework for the regulation of civil aviation in Australia, encompassing various aspects including airworthiness, safety, and operational standards. Pursuant to section 98 of the Act, the Governor-General is empowered to make regulations necessary for the safety of air navigation. Regulation 39.001 specifically grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, thereby ensuring that the continuing airworthiness of these aircraft is maintained in accordance with international standards. This legislative instrument, being a disallowable instrument under section 46A of the Acts Interpretation Act 1901, is subject to the oversight provided by the Legislative Instruments Act 2003. Geographically, the application of these directives extends nationally, aligning with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of States of Design and States of Registry in maintaining airworthiness. While the ADs are issued under international obligations and in response to directives from the State of Design, no public consultation is required, and the Office of Best Practice Regulation has determined that these directives do not necessitate a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 provides the overarching framework for aviation safety in Australia, enabling the Governor-General to make regulations for the safety of air navigation. Under section 98, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs are essential for maintaining the continuing airworthiness of aircraft and are issued by states that design or register the aircraft.
The obligations imposed on the parties governed by this Act are significant. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to the States of Registry. The State of Registry, such as Australia in this case, must then develop or adopt requirements to ensure that individual aircraft remain airworthy. When the State of Design issues an AD, the State of Registry must assess this information and, if necessary, issue a corresponding AD to enforce the State of Design's requirements. In this instance, CASA, Australia’s national airworthiness authority, assessed the US Federal Aviation Administration’s (FAA) AD 2008-05-17 for MD Helicopters model 600N helicopters and issued Australian AD/HU 369/108, Amendment 2.
There are no specified civil or criminal consequences for non-compliance with an AD in the provided text. However, it is implied that failure to comply with an AD could result in serious safety risks and potential legal consequences for the aircraft operator, as ADs are designed to ensure the continuing airworthiness of aircraft. Non-compliance with an AD could also lead to enforcement actions by CASA, which may include grounding of the aircraft, fines, or other regulatory sanctions. The effectiveness of these measures relies on the cooperation of the aircraft operators and the enforcement capabilities of CASA.
