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 170/51 affecting Cessna 172 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 170/51. The cancellation will become effective on 13 March 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 Acting 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, enacted by the Australian Parliament, was established to ensure the safety and efficiency of civil aviation within Australia. One of the mechanisms introduced under this Act is the ability for the Governor-General to issue regulations in the interest of air navigation safety. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs are critical in maintaining the continuing airworthiness of aircraft and are aligned with the obligations under the Convention on International Civil Aviation. The Act, in conjunction with the Civil Aviation Safety Regulations 1998, ensures that Australia adheres to international standards while regulating its aviation safety framework. The policy objective is to safeguard public safety and to uphold the integrity of Australia's civil aviation system by mandating necessary safety measures.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 are instrumental in regulating the safety and airworthiness of aircraft within Australia. The Act, which pertains to the Commonwealth jurisdiction, empowers the Governor-General to enact regulations that ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and are aligned with the continuing airworthiness requirements outlined in Annex 8 of the Convention on International Civil Aviation. The ADs mandate that the State of Design, typically the country where the aircraft type is designed, provides necessary information to ensure the aircraft's continued airworthiness. The State of Registry, in this case, Australia, must then assess this information and, if deemed necessary, issue its own ADs to enforce the required safety measures. The AD/CESSNA 170/51, which was issued concerning Cessna 172 aircraft, has been cancelled by CASA following an assessment, and this cancellation reflects Australia’s adherence to international civil aviation obligations, thereby obviating the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 allow for the issuance of airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft (s. 98 and reg. 39.001). These ADs are legislative instruments, as stipulated in the Legislative Instruments Act 2003 and the Acts Interpretation Act 1901 (reg. 39.001(5)). ADs are critical for maintaining the safety standards of aircraft and are issued by the Civil Aviation Safety Authority (CASA) under the authority of the Governor-General and in accordance with international civil aviation conventions.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose obligations on CASA to issue ADs for specific types of aircraft or aeronautical products when necessary for safety reasons. CASA must also ensure that the State of Registry of an aircraft complies with the continuing airworthiness requirements. When a State of Design issues an AD, CASA is required to assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian aircraft meet international safety standards.
The Civil Aviation Safety Regulations 1998 establish the framework under which CASA can issue and cancel ADs. Under these regulations, ADs are mandatory and non-negotiable, and compliance is necessary to maintain the airworthiness of aircraft. Failure to comply with an AD can result in serious safety risks, including the potential grounding of an aircraft.
There are significant consequences for non-compliance with ADs. The Act and the Regulations do not explicitly detail offences or penalties for failing to comply with ADs, but non-compliance can lead to severe civil or criminal consequences. The potential penalties may include fines, imprisonment, or both, depending on the severity of the safety breach and the discretion of the court. Additionally, aircraft operators and owners may face operational restrictions or the grounding of their aircraft by CASA until compliance is achieved.
