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/DHA-3/10 affecting De Havilland DHA-3 (Drover) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHA-3/10. The cancellation will become effective on 20 November 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, 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 Australian Parliament, was introduced to ensure the safety of air navigation and to regulate civil aviation within Australia. Under this Act, the Governor-General is empowered to make regulations to maintain the safety of air navigation, while the Civil Aviation Safety Regulations 1998 outline the mechanisms by which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft and aeronautical products. These ADs, being legislative instruments, serve as a key regulatory tool in fulfilling Australia's obligations under the Convention on International Civil Aviation, particularly the responsibilities of the State of Design and State of Registry regarding aircraft airworthiness. In a specific instance, CASA cancelled Australian AD/DHA-3/10, affecting De Havilland DHA-3 (Drover) model aeroplanes, due to the resolution of the unsafe condition identified, and no public consultation was necessary given the international obligations underpinning this action.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, establish the framework for issuing airworthiness directives (ADs) which apply to specific types of aircraft or aeronautical products to ensure the safety of air navigation. The Civil Aviation Safety Authority (CASA) has the authority to issue these directives as outlined in regulation 39.001, which also classifies ADs as disallowable instruments under the Acts Interpretation Act 1901. This means ADs are subject to legislative scrutiny and fall under the purview of the Legislative Instruments Act 2003. The geographic scope of these regulations extends nationally, applying to all aircraft registered in Australia and ensuring compliance with international standards set forth by the International Civil Aviation Organization (ICAO) through Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA, is responsible for the continuing airworthiness of aircraft within its jurisdiction, ensuring they meet necessary safety standards. The application of these regulations does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation, given the nature of ADs. The AD/DHA-3/10 concerning De Havilland DHA-3 (Drover) model aeroplanes, issued by CASA, has been cancelled due to the elimination of the unsafe condition, reflecting Australia’s commitment to international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988 (s 98) and the Civil Aviation Safety Regulations 1998 (s 39.001) provide the framework for the issuance of airworthiness directives (ADs). These directives are regulatory instruments designed to ensure the ongoing safety of aircraft and aeronautical products. The Governor-General has the authority to make regulations under section 98, and these regulations allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. The State of Design, which is the country where the aircraft was originally designed, must ensure the continuing airworthiness of the aircraft type and provide necessary information to the State of Registry. The State of Registry, in this case, Australia, is responsible for the individual aircraft’s ongoing airworthiness and must develop or adopt requirements to ensure this. CASA, acting under these regulations, has the authority to issue ADs to address safety concerns and ensure compliance with safety standards. In the specific case of the De Havilland DHA-3 (Drover), CASA issued AD/DHA-3/10, which has now been cancelled as the unsafe condition it addressed no longer exists.
Failure to comply with ADs can have serious consequences. While specific penalties for non-compliance with ADs are not detailed in the text, the overarching legal framework implies potential civil or criminal penalties for not adhering to these safety directives. Non-compliance could potentially lead to severe consequences, including grounding of the aircraft, fines, or even criminal charges depending on the severity of the safety issue. The authority of CASA to enforce compliance underscores the critical importance of adhering to these directives to maintain the safety of air navigation.
Given the international nature of aviation, Australia’s obligations under the Convention on International Civil Aviation play a crucial role in the issuance and cancellation of ADs. Australia’s cancellation of AD/DHA-3/10 aligns with its responsibilities under this international convention, ensuring that the country adheres to global safety standards. This international context also means that ADs do not require consultation with the Australian public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This reflects the balance between national safety measures and international aviation governance.
