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.
CASA issued AD/DAUPHIN/29 affecting Eurocopter SA365 Dauphin helicopters in 1991. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 27 August 2009. No replacement AD is required as the original unsafe condition no longer exists.
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, Initial Airworthiness, in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, serves as a foundational piece of legislation aimed at ensuring the safety and efficiency of civil aviation in Australia. This Act empowers the Civil Aviation Safety Authority (CASA) to issue regulations and directives that maintain and enhance the safety of air navigation. One such regulatory tool is the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. The ADs are legislative instruments that facilitate the ongoing maintenance of aircraft safety by addressing specific safety concerns identified with particular types of aircraft or aeronautical products. The cancellation of an existing AD, such as AD/DAUPHIN/29 for Eurocopter SA365 Dauphin helicopters, reflects the resolution of previously identified safety issues, thus reducing the regulatory burden and streamlining aviation safety measures. This action is taken in accordance with the legislative framework established by the Civil Aviation Act and the Civil Aviation Safety Regulations, ensuring that CASA's regulatory activities remain aligned with international standards and practices as outlined in the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. These directives, which are legislative instruments, apply to specific kinds of aircraft or aeronautical products and are designed to maintain or ensure the continuing airworthiness of these items. The scope of these regulations is both jurisdictional and functional, applying to all aircraft registered in Australia and ensuring compliance with international standards as set out in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in this context means Australia for domestically registered aircraft, is responsible for implementing these directives and ensuring that the aircraft under its jurisdiction meet the required safety standards. Additionally, the State of Design, typically the country where the aircraft was manufactured, must provide necessary information to support the continuing airworthiness of the aircraft type. The ADs are a critical tool in this regulatory framework, and their issuance or cancellation, such as the case with AD/DAUPHIN/29 for Eurocopter SA365 Dauphin helicopters, is governed by CASA's responsibilities and authorities under the Act. The specific AD in question, which was issued in 1991 and subsequently cancelled in 2009, demonstrates CASA’s commitment to adapting regulations in response to evolving safety considerations.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments and serve to ensure the safety of air navigation in line with section 98 of the Civil Aviation Act 1988. Regulation 39.001(5) highlights that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and must be made in accordance with the Legislative Instruments Act 2003. These directives are integral to maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. Specifically, the State of Design is responsible for ensuring the ongoing airworthiness of an aircraft type, while the State of Registry is tasked with the continuing airworthiness of individual aircraft, developing or adopting appropriate requirements as necessary.
In fulfilling these obligations, CASA issued AD/DAUPHIN/29 in 1991, which pertained to Eurocopter SA365 Dauphin helicopters. After a thorough review, CASA decided to cancel this directive, effective 27 August 2009. This cancellation signifies that the original unsafe condition no longer exists, and thus, no replacement AD is required. It is important to note that no consultation with the Australian public was conducted on this cancellation, as it results in a reduction of the regulatory burden. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement, further streamlining the process.
Violating or failing to comply with the provisions set forth in the Civil Aviation Safety Regulations 1998, including the issuance and adherence to ADs, may result in civil or criminal penalties. While the specific penalties are not outlined in the provided text, it is common for breaches of aviation safety regulations to incur fines and potential imprisonment under Australian law. These consequences underscore the importance of adhering to ADs and other safety directives to maintain the highest standards of aviation safety. CASA’s role in issuing and cancelling ADs is thus critical in ensuring compliance and upholding safety within the aviation industry.
