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/S-76/39 Amendment 1 affecting Sikorsky S-76A model Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/S-76/39 Amendment 1. The cancellation will become effective on 2 July 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 legal framework for the regulation of civil aviation in Australia, addressing the need for safety and efficiency in air navigation. The Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, with specific authority given to the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. This regulation allows CASA to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products, which are critical for ensuring the continuing airworthiness of aircraft as mandated by international conventions such as Annex 8 to the Convention on International Civil Aviation. ADs are legislative instruments subject to disallowance and are essential tools for both States of Design and States of Registry to maintain and communicate necessary safety standards for aircraft. The issuance and cancellation of such directives, such as the recent cancellation of AD/S-76/39 Amendment 1 for Sikorsky S-76A model Helicopters, reflect the dynamic nature of aviation safety regulation and the commitment to upholding international safety standards.
Scope and Application
The Civil Aviation Act 1988, through the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) which are regulatory instruments aimed at ensuring the continuing safety of aircraft and aeronautical products in Australia. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Such directives are necessary to maintain compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must ensure the aircraft’s ongoing compliance with airworthiness requirements. CASA, as Australia's national airworthiness authority, must assess and potentially issue Australian ADs to align with those issued by other countries when they pertain to aircraft registered in Australia. The application of these regulations extends to all entities and individuals involved in the registration and operation of aircraft within Australia, ensuring that the safety standards mandated by these ADs are uniformly applied across the aviation industry.
Key Provisions
The Civil Aviation Act 1988 and its associated regulations, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are considered legislative instruments, as stipulated by the Legislative Instruments Act 2003 (section 6). The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to ensure the continuing airworthiness of an aircraft type. This information is often communicated through ADs, which are issued by most ICAO Contracting States. The State of Registry of an individual aircraft, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction. If a State of Design issues an AD for a type of aircraft on the Australian Register, CASA must assess this information and issue an Australian AD if appropriate.
The obligations imposed on parties governed by these regulations include adherence to the continuing airworthiness requirements set forth in ADs. Specifically, aircraft owners and operators must comply with the mandates issued in ADs to maintain the safety of their aircraft. CASA, as the national airworthiness authority, has the responsibility to assess international ADs and determine if they need to be implemented in Australia. This involves evaluating the information provided by the State of Design and deciding whether an Australian AD is necessary. Furthermore, any amendments or cancellations of ADs must be communicated effectively to ensure that all relevant parties are aware of the changes and can comply with the updated requirements.
Failure to comply with ADs can result in various civil and criminal consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to enforcement actions, including fines and potential legal proceedings. The specific penalties for non-compliance can vary, but the Act provides for substantial fines, which can reach up to $222,200 for corporations and $44,440 for individuals, depending on the severity of the breach. In severe cases, continued non-compliance can result in more stringent penalties, including potential criminal charges. The regulations emphasize the importance of adhering to ADs to maintain the highest safety standards in civil aviation.
