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/FU24/55 affecting Fletcher FU24-950 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/FU24/55. The cancellation will become effective on 7 May 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, Systems and New Technologies, 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 establish a regulatory framework for ensuring the safety of civil aviation in Australia. One of its key provisions is section 98, which allows the Governor-General to make regulations for the purposes of the Act, particularly in the interests of the safety of air navigation. Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, as outlined in regulation 39.001. These directives are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and their creation is regulated under the Legislative Instruments Act 2003. The purpose of these regulations is to align with international standards set forth in Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design and mandates that the State of Registry must ensure the airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, plays a critical role in this process by issuing Australian ADs when necessary, reflecting the international standards and ensuring compliance with safety obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, as an instrument of the Civil Aviation Act 1988, apply to all entities involved in the operation and maintenance of aircraft registered in Australia, ensuring they adhere to the safety standards set forth by the Civil Aviation Safety Authority (CASA). This includes aircraft operators, maintenance service providers, and aircraft manufacturers, among others, whose conduct and transactions are governed to maintain the safety of air navigation as per international standards, particularly those set out by the International Civil Aviation Organization (ICAO). The jurisdiction of these regulations extends nationally across Australia, with CASA being the authority responsible for enforcing these safety standards and issuing airworthiness directives as necessary. Airworthiness directives, which are legislative instruments under the Acts Interpretation Act 1901, are issued to address safety issues identified with specific types of aircraft or aeronautical products, and they apply to all relevant aircraft registered in Australia. The application of these regulations is comprehensive and inclusive of all aircraft types within the Australian Register, with no exclusions or exemptions specified within the text provided, ensuring a uniform standard of airworthiness is maintained.
Key Provisions
The Civil Aviation Act 1988 (sections 98) empowers the Governor-General to establish regulations for the safety of air navigation, while 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. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is classified as a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These directives are critical for ensuring the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design has the overarching responsibility for an aircraft type's airworthiness and must provide necessary information to the State of Registry, which must then adopt or develop requirements to ensure the aircraft's ongoing airworthiness.
The obligations under these provisions require CASA to assess any airworthiness directives issued by the State of Design for aircraft types registered in Australia. If an AD is deemed appropriate, CASA must issue a corresponding Australian AD to enforce the required safety measures. For instance, AD/FU24/55, which affected Fletcher FU24-950 model aircraft, was assessed by CASA and subsequently cancelled because the unsafe condition no longer existed. This cancellation took effect on 7 May 2009, and no replacement AD was necessary. The process of cancelling the AD was carried out in accordance with Australia's obligations under the Convention on International Civil Aviation, and thus did not require public consultation or a Regulatory Impact Statement.
The implications of breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. Failure to comply with an airworthiness directive can lead to serious safety hazards, potentially resulting in severe consequences for both passengers and crew. The penalties for non-compliance can include substantial fines and, in severe cases, criminal charges. For example, under section 113 of the Civil Aviation Act 1988, individuals found guilty of violating airworthiness requirements can be fined up to $330,000 for corporations or $66,000 for individuals, along with potential imprisonment. Such stringent measures underscore the critical importance of adhering to ADs to maintain the high safety standards required in the aviation industry.
