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/AC/8 affecting all Twin Aero Commander aircraft models. CASA has assessed this AD and as a result has cancelled Australian AD/AC/8. The cancellation will become effective on
28 August 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, enacted by the Commonwealth Parliament, governs civil aviation in Australia and seeks to ensure the safety and efficiency of air navigation. To further detail the regulatory framework for ensuring the safety of aircraft, the Civil Aviation Safety Regulations 1998 were established. One of the significant provisions of these regulations is the ability for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. These directives are legislative instruments, as specified by subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901, and are critical in maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The ADs are designed to address safety issues and ensure compliance with international standards, thereby safeguarding the interests of the public and the integrity of the aviation industry.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the regulation of civil aviation in Australia, with a particular emphasis on the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are legislative instruments, as they are disallowable under section 46A of the Acts Interpretation Act 1901 and are governed by the Legislative Instruments Act 2003. The ADs are integral to ensuring the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for maintaining the airworthiness of an aircraft type and requiring necessary information to be shared with States of Registry. In Australia, CASA, as the national airworthiness authority, assesses information from the State of Design and, if appropriate, issues Australian ADs to enforce the requisite safety measures. This process ensures compliance with international standards and obligations while maintaining the safety of air navigation within Australia.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for 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 necessary for the safety of air navigation. 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. These ADs are legislative instruments as defined under section 6 of the Legislative Instruments Act 2003 and are disallowable under section 46A of the Acts Interpretation Act 1901. Essentially, ADs serve as a regulatory mechanism to ensure that aircraft maintain their airworthiness standards as outlined by the State of Design, which holds overarching responsibility for the continuing airworthiness of an aircraft type.
The obligations imposed by these regulations are significant for both CASA and the aircraft operators. CASA, as the national airworthiness authority, is tasked with assessing information provided by the State of Design, which is the country where the aircraft was designed. If CASA determines that an AD issued by a State of Design pertains to aircraft on the Australian Register, CASA must either adopt or develop equivalent requirements and issue an Australian AD. This ensures that the safety standards set by the State of Design are implemented in Australia. Aircraft operators, on the other hand, are required to comply with these ADs, which may include maintenance checks, modifications, or operational limitations. Failure to adhere to the ADs can result in the aircraft being deemed unairworthy, thereby compromising safety.
Non-compliance with ADs can lead to serious consequences, both civil and criminal. Under the Civil Aviation Act 1988, failure to comply with an AD can result in a range of penalties, including fines and imprisonment. Specifically, section 57 of the Act stipulates that a person who contravenes a direction under an AD can be liable to a fine of up to $22,200 for individuals and $111,000 for corporations, alongside potential imprisonment. Additionally, CASA can take enforcement actions such as grounding the aircraft or imposing operational restrictions. These stringent measures underscore the importance of adhering to ADs in maintaining aviation safety.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for the issuance and enforcement of ADs in Australia. CASA’s role in assessing and implementing these directives is crucial to ensuring that aircraft on the Australian Register meet international safety standards. Operators must comply with these directives to maintain the airworthiness of their aircraft. Non-compliance can result in severe penalties, reinforcing the critical importance of adhering to these regulatory requirements.
