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
The Civil Aviation Safety Authority or its predecessors issued AD/DHC-1/15 affecting De Havilland DHC-1 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-1/15. The cancellation will become effective on 25 September 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 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 comprehensive legislative framework for ensuring the safety and efficiency of civil aviation in Australia. This Act empowers the Governor-General to make regulations aimed at enhancing the safety of air navigation. One such regulation, established under the Civil Aviation Safety Regulations 1998, is the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are designed to maintain or improve the continuing airworthiness of aircraft by addressing specific safety issues. The ADs are legislative instruments subject to disallowance and review as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Civil Aviation Act 1988, in concert with international conventions such as Annex 8 to the Convention on International Civil Aviation, ensures that Australia aligns with global standards for aircraft safety and airworthiness management.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. Under this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments, are subject to disallowance under section 46A of the Acts Interpretation Act 1901 and are governed by the provisions of the Legislative Instruments Act 2003. The application of these regulations extends to any aircraft registered in Australia, with the State of Registry bearing the responsibility for ensuring the continuing airworthiness of these aircraft, in alignment with the requirements set forth in Annex 8 to the Convention on International Civil Aviation. The scope of the ADs encompasses the maintenance of airworthiness standards and the dissemination of continuing airworthiness information, which is crucial for the safety of air navigation in Australia. The application of these regulations is not limited by jurisdictional boundaries within Australia, as they are designed to ensure national and international compliance with aviation safety standards.
Key Provisions
The key operative sections of the Civil Aviation Safety Regulations 1998 that are relevant here are sections 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (s 39.001). These ADs are designed to maintain the safety of air navigation as per section 98 of the Civil Aviation Act 1988. Furthermore, subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, by virtue of section 6 of the Legislative Instruments Act 2003, an AD is considered a legislative instrument.
Under these provisions, the Civil Aviation Safety Authority has issued AD/DHC-1/15 for De Havilland DHC-1 model aeroplanes, but subsequently, after a thorough assessment, CASA has decided to cancel this directive. This cancellation is effective from 25 September 2008, and no replacement AD is required because the unsafe condition identified in the original directive no longer exists. This action was taken in accordance with Australia's obligations under the Convention on International Civil Aviation, specifically Annex 8, which places the responsibility for continuing airworthiness of an aircraft type with the State of Design and mandates the provision of necessary information to the States of Registry.
The obligations imposed by these regulations include the requirement for the State of Registry to develop or adopt specific requirements to ensure the continuing airworthiness of aircraft, as outlined in Annex 8 of the Convention. Moreover, the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type to the States of Registry. CASA, as the regulatory authority, has the duty to issue ADs when necessary and to cancel them when the identified unsafe conditions no longer exist.
In terms of legal consequences, breaches of the Civil Aviation Safety Regulations 1998 could result in both civil and criminal penalties. While the specific penalties are not detailed in the provided text, they generally include fines and potential imprisonment, depending on the severity and nature of the breach. The exact penalties would be determined by the relevant courts based on the specifics of the case and the applicable provisions of the Civil Aviation Act 1988 and other related legislation.
