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 340/10 affecting Cessna 340 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 340/10. The cancellation will become effective on 5 June 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, Systems and New Technologies 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 establish a framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the sector. This legislation grants the Governor-General the authority to create regulations aimed at enhancing the safety of air navigation, with specific responsibilities delegated to the Civil Aviation Safety Authority (CASA). Complementing the Civil Aviation Act 1988, the Civil Aviation Safety Regulations 1998 empower CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby facilitating the maintenance of aircraft safety standards. These ADs serve as a crucial tool in ensuring the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The legislative process for ADs is stringent, reflecting Australia's commitment to global aviation safety norms, while the cancellation of specific ADs, such as AD/CESSNA 340/10, underscores the dynamic nature of aviation safety regulations.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, outlines the framework within which airworthiness directives (ADs) are issued in Australia. Specifically, section 98 of the Act empowers the Governor-General to create regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These directives, which are considered legislative instruments under the Legislative Instruments Act 2003, are integral to maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the original airworthiness of an aircraft type, must provide necessary information to the States of Registry to ensure compliance with airworthiness standards. CASA, acting as Australia’s national airworthiness authority, assesses these international directives and may issue corresponding Australian ADs if necessary. For instance, CASA issued and subsequently cancelled AD/CESSNA 340/10 for Cessna 340 aircraft due to the resolution of an unsafe condition, reflecting Australia’s commitment to international aviation safety standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 specifies that ADs are disallowable instruments, and thus are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory structure is aligned with Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having primary responsibility for the continuing airworthiness of an aircraft type, and the State of Registry as responsible for the continuing airworthiness of individual aircraft.
The obligations imposed by these provisions include the requirement for CASA to assess any ADs issued by the State of Design and to issue corresponding Australian ADs as necessary to maintain the safety standards. In the specific case of AD/CESSNA 340/10 affecting Cessna 340 aircraft, CASA has assessed the AD and decided to cancel it, effective from 5 June 2008, as the unsafe condition identified in the directive no longer exists. This decision aligns with Australia's obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was deemed necessary for this AD cancellation.
The consequences of breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can be severe. The Act and Regulations outline both civil and criminal penalties for non-compliance with ADs and other safety regulations. Civil penalties may include fines and other monetary penalties, while criminal penalties can result in imprisonment. The exact penalties depend on the nature and severity of the breach but can be substantial, reflecting the critical importance of adhering to aviation safety standards to protect public safety and the integrity of the aviation system. The AD cancellation itself does not introduce new penalties but ensures that the aviation safety regulations remain current and effective in mitigating risks to aircraft and passengers.
