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/CESSNA 400/73 affecting Cessna 441 model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 25 September 2008. 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, 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 was enacted to provide a comprehensive framework for regulating civil aviation in Australia, ensuring safety, efficiency, and orderly growth of civil aviation. One of the key mechanisms within this framework is the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. The Civil Aviation Safety Regulations 1998, which are subsidiary legislation under the Act, empower the Civil Aviation Safety Authority (CASA) to issue such directives. This legislative infrastructure was introduced to address the need for a robust regulatory system that ensures the safety and airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The policy objective is to safeguard the safety of air navigation and the continuing airworthiness of aircraft in accordance with international conventions and obligations. CASA, acting as Australia's national airworthiness authority, plays a pivotal role in issuing and managing ADs to ensure compliance with these safety standards.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) that pertain to specific types of aircraft or aeronautical products. These regulations are designed to uphold the safety of air navigation in Australia and beyond. ADs serve as a crucial mechanism for ensuring the continuing airworthiness of aircraft by mandating specific safety measures or corrective actions when necessary. This regulatory framework applies to aircraft registered in Australia, including those manufactured domestically and those imported from other jurisdictions. The application of these regulations is in line with international standards set by the Convention on International Civil Aviation, specifically Annex 8, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type, and the State of Registry as responsible for the individual aircraft. The issuance and enforcement of ADs by CASA are pivotal in maintaining compliance with both national and international aviation safety standards. The ADs are legislative instruments and are subject to disallowance and review as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, respectively.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for the issuance and management of airworthiness directives (ADs) to ensure the safety of aircraft in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations that promote the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in section 6 of the Legislative Instruments Act 2003, and they are critical tools for maintaining the continuing airworthiness of aircraft, in line with the requirements of Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and the Regulations on parties and entities include the responsibility of the State of Design to provide necessary information to ensure the continuing airworthiness of an aircraft type, as well as the duty of the State of Registry to develop or adopt requirements to ensure the airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and, if appropriate, issue Australian ADs to enforce these requirements. This process is exemplified by the issuance and subsequent cancellation of AD/CESSNA 400/73, which affected Cessna 441 model aircraft. The cancellation of this directive, which took effect on 25 September 2008, was based on Australia’s obligations under international conventions and the assessment by CASA that the unsafe condition no longer existed.
The legislation also outlines the consequences of non-compliance with ADs. While the specific penalties for breaching ADs are not detailed in the provided text, it is implicit that such breaches could lead to civil or criminal liability, given the safety-critical nature of airworthiness directives. Furthermore, the process for issuing ADs, as stipulated by section 39.001(5) of the Civil Aviation Safety Regulations 1998, ensures that any legislative instrument must adhere to the disallowance provisions under section 46A of the Acts Interpretation Act 1901. Given the safety implications, the consequences of non-compliance could potentially include severe penalties, although the exact nature of these penalties would need to be examined within the broader legislative context.
