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/CESSNA 170/31 Amendment 1 affecting Cessna 172 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 170/31 Amendment 1. The cancellation will become effective on 14 February 2008. 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 Acting Manager, Systems and New Technologies 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 to establish a comprehensive framework for civil aviation in Australia, provides the legislative basis for ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to create regulations that serve the interests of aviation safety, including the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. ADs are critical for maintaining the continuing airworthiness of aircraft, and they are issued by the Civil Aviation Safety Authority (CASA) in accordance with Annex 8 of the Convention on International Civil Aviation. The process involves the State of Design issuing an AD for a specific aircraft type, which CASA then assesses and may adapt for Australian aircraft on the Australian Register. This legislative instrument, AD/CESSNA 170/31 Amendment 1, affecting Cessna 172 aircraft, was subsequently cancelled by CASA after determining that the unsafe condition it addressed no longer existed. This cancellation aligns with Australia's international obligations and has been executed without public consultation, as ADs are deemed not to require a Regulatory Impact Statement. The AD cancellation was made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, pursuant to the provisions of the Civil Aviation Act.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, applies to the issuance of airworthiness directives (ADs) which are crucial for ensuring the safety of air navigation. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specified types of aircraft or aeronautical products, which are then considered legislative instruments under the Legislative Instruments Act 2003. The ADs are issued in accordance with Australia’s obligations under the Convention on International Civil Aviation, specifically Annex 8, which places the responsibility of continuing airworthiness on the State of Design and the State of Registry. In practice, this means CASA must assess any ADs issued by a State of Design and, if deemed necessary, issue corresponding ADs for aircraft registered in Australia. The application of these regulations is national in scope, covering all aircraft and aeronautical products within Australia, and they extend to the specific requirements and cancellations of ADs as necessary to maintain airworthiness standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for issuing airworthiness directives (ADs) (sections 98, 39.001, and 39.001(5)). Specifically, section 98 allows the Governor-General to make regulations for air navigation safety, and regulation 39.001 permits the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies an AD as a disallowable instrument, thereby making it a legislative instrument under the Legislative Instruments Act 2003.
These provisions impose several obligations and requirements on the parties involved. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure it, as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in Australia's case is CASA, must then assess this information and issue an Australian AD if appropriate, ensuring that the aircraft on the Australian Register meet the continuing airworthiness requirements. CASA, as the national airworthiness authority, must therefore evaluate any ADs issued by the State of Design and act accordingly.
Failure to comply with the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various consequences. Although specific offences, penalties, or consequences for breaching these regulations are not detailed in the provided text, the general nature of regulatory non-compliance could lead to legal actions or penalties under Australian law. The seriousness of the consequences would depend on the specific breach and the impact it has on aviation safety.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the legal basis for issuing ADs and managing airworthiness in Australia. The State of Design and the State of Registry, represented by CASA, have clear responsibilities under these regulations to ensure the safety of aircraft. While the specific penalties for non-compliance are not detailed here, the overarching aim is to maintain high safety standards in civil aviation.
