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/HU 269/32 Amendment 1 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/32 Amendment 1. The cancellation will become effective on 7 May 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 was enacted to provide a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of aviation safety, with specific provisions allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft and aeronautical products. These ADs are legislative instruments designed to maintain and ensure the continuing airworthiness of aircraft, aligning with Australia’s obligations under the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing and implementing these directives, ensuring compliance with international standards and the safety of air navigation within Australian jurisdiction.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively establish the framework within which airworthiness directives (ADs) are issued and managed in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs concerning specific types of aircraft or aeronautical products in accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998. This regulatory power is derived from section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations in the interests of air navigation safety. These ADs are legally binding and are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The issuance and management of ADs are governed by international standards set out in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. Consequently, when a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, is required to assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements of the State of Design. The AD process is integral to ensuring the safety and airworthiness of aircraft registered in Australia, reflecting Australia’s commitment to international aviation safety standards.
Key Provisions
The key operative sections of the Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provide the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) under regulation 39.001. These ADs serve as critical tools for ensuring the safety and continuing airworthiness of aircraft, and they are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003. Under subregulation 39.001(5), ADs are disallowable instruments as per section 46A of the Acts Interpretation Act 1901, reinforcing their regulatory nature. The authority to issue these directives is rooted in the overarching responsibility of the State of Design, which must provide necessary information to ensure the airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations and requirements imposed by these regulations primarily fall on CASA, as Australia's national airworthiness authority. When a State of Design issues an AD concerning a type of aircraft registered in Australia, CASA must review and assess this information. If deemed appropriate, CASA must then issue a corresponding Australian AD to enforce the requirements stipulated by the State of Design. Additionally, the State of Registry for individual aircraft is mandated to ensure the continuing airworthiness of aircraft registered under its jurisdiction. This includes developing or adopting necessary requirements to maintain airworthiness, as mandated by Annex 8.
Failure to comply with ADs can lead to significant consequences. The Civil Aviation Act 1988 and associated regulations impose strict obligations on aircraft operators and owners to adhere to the mandates outlined in ADs. Non-compliance can result in serious safety risks, and CASA has the authority to take enforcement actions against entities that fail to comply with these directives. The potential penalties for breaching these regulations can include substantial fines, imprisonment, or both, depending on the severity of the non-compliance and the impact on aviation safety. The specific penalties are not detailed in the provided text, but they are generally severe, reflecting the critical importance of adhering to airworthiness directives.
The legislative process for issuing and cancelling ADs also includes specific procedural requirements. For instance, the cancellation of AD/HU 269/32 Amendment 1 for Schweizer (Hughes) 269 series Helicopters, effective from 7 May 2009, was carried out by CASA after assessing that the unsafe condition no longer existed. This cancellation was made in accordance with subsection 84A(2) of the Act and involved no consultation with the public or the requirement for a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was issued by the Manager Systems and New Technologies within the Airworthiness Engineering Group at CASA, ensuring that the process was followed by qualified personnel.
