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 369/25 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/25. The cancellation will become effective on 4 June 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, enacted by the Parliament of Australia, provides the legislative framework for ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations, including those pertaining to airworthiness directives, which are critical in maintaining the safety standards of aircraft and aeronautical products. Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives for specific types of aircraft or aeronautical products. The issuance of these directives is essential for continuing the airworthiness of aircraft, as mandated by international standards set by the International Civil Aviation Organization (ICAO) and its member states. The policy objective of these regulations is to ensure the safety of air navigation and the continued airworthiness of aircraft through effective regulatory measures.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework within which the Civil Aviation Safety Authority (CASA) issues airworthiness directives (ADs). The Act applies to the Governor-General, who has the authority to make regulations under section 98, and CASA, which is empowered under regulation 39.001 to issue ADs for specified types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Legislative Instruments Act 2003, and they are integral to the international standards set by Annex 8 to the Convention on International Civil Aviation. The ADs ensure compliance with the continuing airworthiness of aircraft, with the State of Design bearing the primary responsibility for providing necessary information, while the State of Registry must implement these directives to maintain safety standards. This regulatory framework is applicable nationally, with CASA acting on behalf of Australia to ensure that the ADs issued by the State of Design are assessed and, if necessary, translated into Australian ADs. The scope of these regulations extends to all aircraft and aeronautical products within Australia’s jurisdiction, ensuring that safety standards are uniformly enforced across the country.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. An AD is a legislative instrument that serves as a crucial tool for ensuring the continuing airworthiness of aircraft and aeronautical products. This process is aligned with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds the primary responsibility for the ongoing airworthiness of an aircraft type. Conversely, the State of Registry is tasked with ensuring the airworthiness of individual aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements outlined by the State of Design.
Compliance with ADs is essential for maintaining the safety standards set forth by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Operators and owners of aircraft must adhere to the directives issued by CASA to ensure their aircraft meet the required safety standards. This includes following the specific maintenance, repair, and replacement procedures outlined in the ADs. Failure to comply with these directives can result in serious safety risks, including the potential for accidents or incidents that could endanger lives and property. CASA has the authority to enforce compliance through various measures, including inspections, audits, and the imposition of fines or other penalties for non-compliance.
Under the Civil Aviation Safety Regulations 1998, there are specific consequences for non-compliance with ADs. Section 39.001(5) of the Regulations designates ADs as disallowable instruments, meaning that they can be reviewed and disallowed by the Governor-General if found to be inconsistent with the Act. Additionally, under the Legislative Instruments Act 2003, non-compliance with ADs can result in civil or criminal penalties, depending on the severity of the breach. For instance, section 84A(2) of the Civil Aviation Act 1988 outlines the potential penalties for non-compliance, which can include fines up to a certain amount and, in more severe cases, imprisonment. These measures are designed to ensure that all stakeholders, including aircraft operators and owners, take the necessary steps to maintain the airworthiness of their aircraft and comply with the regulatory requirements.
