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/BELL 222/8 Amendment 1 affecting Bell Helicopter Textron Canada (BHTC) 222 series helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/BELL 222/8 Amendment 1. The cancellation will become effective on 30 July 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, 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, enacted by the Australian Parliament, established the framework for ensuring the safety of air navigation and the regulation of civil aviation within Australia. The Act empowers the Governor-General to make regulations, which are integral to maintaining safety standards and ensuring the continuing airworthiness of aircraft. This legislative foundation is complemented by the Civil Aviation Safety Regulations 1998, which, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). ADs serve as a critical tool for communicating safety measures and ensuring that aircraft meet necessary safety standards. The Civil Aviation Act 1988 addresses the need for a robust regulatory framework to manage the complexities of civil aviation, ensuring that safety remains paramount in all operations.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the safety of air navigation in Australia, with particular emphasis on the issuance of airworthiness directives (ADs). These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, which serve as legislative instruments under the Acts Interpretation Act 1901. The ADs mandate the continuing airworthiness of aircraft and are based on international standards set out in Annex 8 to the Convention on International Civil Aviation. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. CASA, as Australia's national airworthiness authority, must then assess this information and issue Australian ADs as required to comply with international obligations. In this context, CASA has cancelled AD/BELL 222/8 Amendment 1 for Bell Helicopter Textron Canada (BHTC) 222 series helicopters, effective from 30 July 2009, due to the resolution of the unsafe condition that originally prompted its issuance. The cancellation of this AD aligns with Australia's commitments under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was deemed necessary for this action.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001, which are legislative instruments according to section 6 of the Legislative Instruments Act 2003. These ADs are critical for maintaining the continuing airworthiness of aircraft and aeronautical products, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, where the aircraft type is designed, is responsible for ensuring airworthiness and must provide necessary information to States of Registry, which in turn must ensure the airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, evaluates this information and, if needed, issues corresponding Australian ADs. For example, CASA assessed and subsequently cancelled the Australian AD/BELL 222/8 Amendment 1 for Bell Helicopter Textron Canada (BHTC) 222 series helicopters, effective from 30 July 2009, as the unsafe condition identified in the original AD no longer exists.
The obligations imposed by these regulations are multifaceted. The State of Design must provide essential information to the States of Registry to ensure the continuing airworthiness of aircraft types, while States of Registry must develop or adopt requirements to ensure the airworthiness of individual aircraft. CASA must assess any ADs issued by States of Design and, if appropriate, issue corresponding Australian ADs. Additionally, entities such as manufacturers, operators, and maintenance organisations must comply with ADs by following the specified procedures or modifications. Failure to comply with an AD can result in the aircraft being deemed unairworthy, leading to potential grounding and significant operational disruptions.
Breaching the requirements set out in ADs can lead to severe consequences. CASA may take enforcement action against non-compliance, which can include fines, suspension, or revocation of airworthiness certificates. The maximum penalties for civil aviation offences are substantial and vary depending on the nature and severity of the offence. For example, under the Civil Aviation Act 1988, individuals can face fines of up to $150,000, while corporations can be fined up to $750,000 for serious breaches. Additionally, individuals can face imprisonment for up to two years, and corporations can face imprisonment for up to five years. These penalties underscore the importance of adhering to ADs to ensure the safety and integrity of air navigation.
