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/INST/26 affecting Navomatic 200A Automatic Pilot Computer amplifiers. CASA has assessed this AD and as a result has cancelled Australian AD/INST/26. The cancellation will become effective on 12 March 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, enacted by the Commonwealth Parliament, is foundational legislation governing civil aviation in Australia. Its primary aim was to ensure the safety and efficiency of air navigation and aircraft operations within Australian airspace. Under the authority of this Act, the Civil Aviation Safety Authority (CASA) has the power to issue airworthiness directives to mandate safety measures and ensure the continuing airworthiness of aircraft. These directives are crucial for maintaining safety standards and are issued in line with international conventions, such as Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. The Civil Aviation Safety Regulations 1998 further detail the processes and requirements for issuing these directives. The cancellation of Australian AD/INST/26 affecting the Navomatic 200A Automatic Pilot Computer amplifiers exemplifies how CASA adheres to international obligations, ensuring that Australian regulations remain aligned with global safety standards.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, governs the issuance and management of airworthiness directives (ADs) in Australia. These regulations apply to all aircraft and aeronautical products registered in Australia, including commercial and private aircraft, as well as their components and systems. The scope of the Act and its associated regulations is primarily focused on ensuring the safety of air navigation and the continuing airworthiness of aircraft. The Civil Aviation Safety Authority (CASA), as Australia's national airworthiness authority, is empowered under the Act to issue ADs for specific types of aircraft or aeronautical products when necessary. These ADs are legislative instruments that must be assessed and may be adopted or modified to suit Australian conditions. The application of the ADs extends to the State of Registry, which is responsible for ensuring the ongoing airworthiness of the individual aircraft in question. The Act and its regulations have a national reach, applying uniformly across Australia. However, the Act also aligns with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which mandates the State of Design to provide necessary information for the continuing airworthiness of aircraft types. In cases where an AD issued by a State of Design affects an aircraft on the Australian register, CASA must evaluate and, if necessary, issue a corresponding Australian AD. The Act does not specify exclusions or exemptions to its application, although the issuance of ADs is subject to the procedural requirements outlined in the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. Section 39.001(5) of the same regulations states that an AD is a disallowable instrument under the Acts Interpretation Act 1901, making it a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These ADs are a crucial tool for maintaining the continuing airworthiness of aircraft as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions primarily fall on CASA, as Australia's national airworthiness authority. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards. The State of Registry for individual aircraft also has a responsibility under Annex 8 to develop or adopt requirements to ensure the continuing airworthiness of aircraft within their jurisdiction.
Under the Civil Aviation Act 1988 and the associated regulations, there are no specific offences or penalties outlined for breaches of ADs in the Act itself. However, failure to comply with an AD can result in severe civil and criminal consequences, including fines and imprisonment. The maximum penalties are not detailed in the text but can be substantial, reflecting the critical nature of airworthiness directives in maintaining aviation safety. It is important for aircraft operators and other relevant parties to adhere strictly to ADs to avoid legal repercussions.
The issuance and cancellation of ADs are governed by a stringent process that adheres to Australia’s obligations under international civil aviation agreements. For instance, AD/INST/26 affecting the Navomatic 200A Automatic Pilot Computer amplifiers was assessed by CASA, leading to its cancellation on 12 March 2009, as the unsafe condition no longer existed. Given that this cancellation aligns with Australia's obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required, as determined by the Office of Best Practice Regulation. The AD was issued 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.
