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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 150/25 affecting Cessna 150 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. No replacement AD is required.
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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive regulatory framework for civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. One of the key provisions of this Act is section 98, which empowers the Governor-General to make regulations necessary for the safety of air navigation. In line with this authority, the Civil Aviation Safety Regulations 1998 were established, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as critical tools in maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. The process of issuing and cancelling such directives, such as the recent cancellation of AD/CESSNA 150/25 for Cessna 150 model aircraft, underscores the commitment to adhering to international standards and ensuring the highest safety benchmarks in civil aviation.
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 types of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901 and governed by the Legislative Instruments Act 2003. The scope of these regulations applies to entities involved in the aviation industry, specifically targeting the maintenance and safety standards of aircraft and aeronautical products within Australia. The geographic reach of these regulations is national, as they are implemented across the Commonwealth under the oversight of CASA. The ADs are designed to ensure compliance with international standards set by the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft. The cancellation of an AD, such as AD/CESSNA 150/25 for Cessna 150 model aircraft, is executed to align with Australia's obligations under the Convention and does not require public consultation or a Regulatory Impact Statement. The AD cancellation is a direct result of CASA's review and adherence to international obligations, reflecting the dynamic nature of regulatory measures in the aviation sector.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to make regulations in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This means that CASA can issue formal instructions to ensure the safety and airworthiness of specific aircraft types or products, which is a key mechanism for maintaining safety standards in the aviation industry (sections 98 and 39.001).
These airworthiness directives are not just informal guidelines; they are legally binding instruments. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are also considered legislative instruments according to section 6 of the Legislative Instruments Act 2003. This means that ADs carry the full weight of the law and must be complied with by the relevant parties. The State of Design, which is the country where the aircraft type was designed, holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry, the country where the aircraft is registered (Annex 8 to the Convention on International Civil Aviation).
In the context of Australian aviation, CASA has the authority to issue and manage these directives. For example, CASA or its predecessors issued AD/CESSNA 150/25 affecting Cessna 150 model aircraft. However, this particular AD has since been reviewed and cancelled by CASA, effective 31 July 2008. The cancellation was due to Australia's obligations under the Convention on International Civil Aviation, and no replacement AD is required. Given the international nature of aviation and the obligations under the Convention, no consultation with the Australian public was deemed necessary for this cancellation, and the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement.
The issuance and cancellation of ADs are governed by strict procedures. The AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. This demonstrates the meticulous and regulated process that underpins the safety measures in civil aviation. The obligations and requirements placed on the parties governed by these regulations are to ensure strict compliance with ADs, as these are critical for maintaining the safety and airworthiness of aircraft. Failure to comply with these directives can lead to severe consequences, including potential criminal and civil penalties, depending on the nature and severity of the breach.
