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.
CASA issued AD/PROCTOR/10, affecting Percival Proctor model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes in the Airworthiness Engineering Branch, 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, governs the regulation of civil aviation in the country and aims to ensure the safety of air navigation. In line with this objective, the Civil Aviation (Airworthiness) Regulations 1998 were made to establish the framework for maintaining the airworthiness of aircraft and aeronautical products. One key provision within these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to address safety concerns for specific types of aircraft or aeronautical products. ADs serve as a mechanism to ensure the continuing airworthiness of aircraft and are a critical tool in maintaining safety standards as mandated by Annex 8 to the Convention on International Civil Aviation. CASA's role includes assessing information from the State of Design and, when necessary, issuing Australian ADs to enforce safety requirements. This legislative framework underscores the commitment to international standards and the safety of air navigation within Australia.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations in the interests of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to ensure compliance with airworthiness standards. In Australia, CASA, as the national airworthiness authority, must review and, if necessary, issue Australian ADs to enforce the requirements of the State of Design for aircraft registered in Australia. The process for issuing and cancelling ADs is outlined in the regulations, and while ADs do not typically require public consultation or a Regulatory Impact Statement, they are subject to internal CASA processes and approvals. The specific AD/PROCTOR/10, which affected Percival Proctor model aircraft, was cancelled by CASA on 17 January 2008, as the safety concerns it addressed were now covered by another AD.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for issuing airworthiness directives (ADs) in Australia. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products. This regulatory approach aligns with international standards set out in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for ensuring the continuing airworthiness of aircraft types, and the State of Registry the duty to implement requirements for individual aircraft.
Under the Civil Aviation Safety Regulations 1998, ADs serve as a critical mechanism for maintaining airworthiness by specifying mandatory actions or conditions that must be met to address identified safety issues. In the context of Australian aviation, CASA acts as the national airworthiness authority, tasked with evaluating information from the State of Design and, if necessary, issuing corresponding Australian ADs. This ensures that safety directives applicable to aircraft registered in Australia are effectively communicated and enforced. For example, CASA issued AD/PROCTOR/10 in 1972 concerning the Percival Proctor model aircraft, which has now been cancelled due to the resolution of the original safety concerns by another AD.
The obligations imposed by these regulations are multifaceted. CASA, as the national airworthiness authority, must meticulously assess the safety directives issued by the State of Design and determine their applicability to aircraft registered in Australia. The State of Registry, in this case, Australia, must then adopt and enforce these directives to maintain the airworthiness of individual aircraft. Furthermore, these obligations extend to ensuring that all stakeholders, including aircraft operators and maintenance personnel, are aware of and comply with the requirements outlined in the ADs.
Failure to comply with the ADs can lead to significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered an offence, potentially resulting in both civil and criminal penalties. Civil penalties can include fines, while criminal penalties might encompass imprisonment, depending on the severity of the breach and the impact on aviation safety. The specific penalties are determined by the courts, taking into account the circumstances of each case. The regulatory framework thus serves to uphold the highest standards of aviation safety by mandating strict compliance with ADs.
