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.
Transport Canada has issued AD CF-2009-32 affecting Bell Helicopter Textron Canada 427 series helicopters. Canada is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/BELL 427/11, which will become effective on 14 August 2009.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, 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 legislative framework for the regulation of civil aviation in Australia, aiming to ensure the safety, efficiency, and orderly development of civil aviation. In line with this objective, the Act empowers the Governor-General to make regulations in the interest of air navigation safety. A significant instrument under this legislative authority is the Civil Aviation Safety Regulations 1998, which, through regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are legislative instruments subject to disallowance, as stipulated in the Legislative Instruments Act 2003. The ADs are crucial for maintaining the continuing airworthiness of aircraft and aeronautical products, fulfilling Australia's commitments under the Convention on International Civil Aviation, particularly Annex 8, which places the responsibility on the State of Design to provide necessary information for airworthiness. CASA, as Australia's national airworthiness authority, assesses and, if necessary, issues Australian ADs to ensure compliance with international standards.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the safety aspects of air navigation in Australia. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs, being disallowable instruments under the Acts Interpretation Act 1901, are considered legislative instruments according to the Legislative Instruments Act 2003. The ADs are integral to ensuring the continuing airworthiness of aircraft as mandated by the Convention on International Civil Aviation, particularly under Annex 8, which places the responsibility of airworthiness on the State of Design and the State of Registry. In the context of Australia, CASA, as the national airworthiness authority, must issue corresponding ADs when necessary, following the lead of the State of Design. This process does not require public consultation or a Regulatory Impact Statement, as it aligns with international obligations and the urgent need to maintain aviation safety standards.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 allow the Governor-General to make regulations for the safety of air navigation (section 98), and the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products (regulation 39.001). An AD is a legislative instrument that is disallowable under section 46A of the Acts Interpretation Act 1901 and must be assessed by CASA when issued by the State of Design (subregulation 39.001(5)).
The Act and Regulations impose several obligations on the parties involved. The State of Design, such as Canada for Bell Helicopter Textron Canada 427 series helicopters, has the responsibility to provide necessary information to ensure the continuing airworthiness of aircraft types (Annex 8 to the Convention on International Civil Aviation). The State of Registry, in this case CASA as Australia’s national airworthiness authority, must assess the information provided by the State of Design and, if appropriate, issue an Australian AD to mandate the requirements (Annex 8). These obligations ensure that the safety standards set forth in international conventions are upheld and that all relevant parties are informed of and comply with the necessary airworthiness requirements.
Failure to comply with an AD can lead to serious legal consequences. Under the Civil Aviation Act 1988, an operator who contravenes an airworthiness directive can face penalties. The Act does not specify exact penalties but indicates that contraventions may be subject to fines and other legal repercussions. The severity of penalties can vary, but they are intended to enforce compliance and ensure the safety of air navigation.
In summary, the legislation sets out a clear framework for the issuance and compliance with airworthiness directives to ensure the safety of aircraft. The obligations imposed on the State of Design and State of Registry are critical to maintaining these safety standards. Any failure to comply with these directives can result in significant penalties, underscoring the importance of adhering to the regulations.
