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-97-18 affecting Eurocopter Canada BO 105 LS-A3 model helicopters. Canada is the State of Design for this model. CASA has assessed this AD and has issued Australian AD/BO 105/22, which will become effective on 27 September 2007.
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 Commonwealth Parliament, establishes the legislative framework for ensuring the safety and efficiency of civil aviation in Australia. The Act empowers the Governor-General to make regulations in the interests of air navigation safety, including the issuance of airworthiness directives (ADs) as per section 98. These ADs are critical for maintaining the continuing airworthiness of aircraft types and are issued by the Civil Aviation Safety Authority (CASA), Australia's national airworthiness authority. The Civil Aviation Safety Regulations 1998 further delineate the procedures for AD issuance, with CASA mandated to respond to ADs issued by the State of Design and ensure compliance with international standards set by the Convention on International Civil Aviation. The legislative objective is to harmonise Australia's airworthiness directives with international standards, ensuring that aircraft registered in Australia meet global safety benchmarks.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments and are issued to ensure the safety of air navigation, aligning with Australia's obligations under the Convention on International Civil Aviation. An AD is issued by CASA when a State of Design issues a corresponding directive, and CASA, as Australia's national airworthiness authority, must assess the information and, if necessary, issue an Australian AD to enforce the requirements. This process ensures the continuing airworthiness of aircraft registered in Australia. The AD is made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act 1988. This legislative framework applies to aircraft and aeronautical products registered in Australia, with a focus on maintaining safety standards as mandated by international aviation conventions.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (s 39.001(5)). These directives are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901 (s 39.001(5)). ADs serve as the primary means of ensuring the continuing airworthiness of aircraft types, aligning with Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case Canada for the Eurocopter Canada BO 105 LS-A3 model helicopters, is responsible for issuing ADs, and CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue corresponding Australian ADs to comply with international obligations (Annex 8).
Entities governed by these regulations must adhere to the airworthiness directives issued by CASA. Specifically, the State of Registry, which in this case is Australia, is mandated to develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction (Annex 8). This includes implementing any ADs issued by CASA in response to directives from the State of Design. The obligations extend to ensuring that all aircraft meet the airworthiness standards stipulated in the applicable ADs, which may include mandatory modifications, inspections, and operational restrictions.
Failure to comply with the requirements set out in the ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to enforcement actions, including fines and other penalties. The specific maximum penalties for breaches may vary but can include substantial financial penalties and, in severe cases, criminal charges. The seriousness of these consequences underscores the importance of adhering to the directives to maintain the safety and airworthiness of aircraft within the Australian airspace.
