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 320/13 affecting Cessna 320 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 320/13. The cancellation will become effective on 8 May 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 provide a comprehensive legal framework governing civil aviation in Australia, addressing the need for safety and regulatory oversight in the aviation industry. This legislation enables the creation of regulations that ensure the safety of air navigation, with the Civil Aviation Safety Regulations 1998 further detailing specific safety measures, including the issuance of airworthiness directives (ADs). These ADs are legislative instruments designed to mandate continuing airworthiness of aircraft and aeronautical products, aligning with international standards set forth by the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority, responsible for issuing ADs based on assessments of information provided by the State of Design and ensuring compliance with both national and international safety standards. The authority to issue and cancel ADs is exercised by CASA under the Act, facilitating the continuous enhancement of aviation safety in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, as part of the Civil Aviation Act 1988, establish the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. These regulations apply to aircraft registered in Australia and are grounded in the overarching obligations of the State of Design and State of Registry under Annex 8 of the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, assumes the responsibility of issuing ADs based on assessments of information provided by the State of Design. In this specific instance, CASA issued and subsequently cancelled an Australian AD for Cessna 320 aircraft, effective from 8 May 2008, due to the resolution of the unsafe condition identified. This legislative instrument is subject to disallowance under section 46A of the Acts Interpretation Act 1901, and is recognised as a legislative instrument under the Legislative Instruments Act 2003. No public consultation or Regulatory Impact Statement is required for the cancellation of such ADs, as determined by the Office of Best Practice Regulation.
Key Provisions
Under the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that promote the safety of air navigation, as specified in section 98. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are crucial for maintaining the continuing airworthiness of aircraft and are recognised internationally, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the aircraft type, must provide necessary information to ensure the aircraft’s ongoing airworthiness. The State of Registry, where the aircraft is registered, must implement these directives to ensure compliance with safety standards.
The obligations under this legislation require CASA to carefully assess any ADs issued by the State of Design for aircraft types registered in Australia. When a foreign AD is issued, CASA must evaluate the information and determine if an Australian AD is necessary. In the case of AD/CESSNA 320/13, which affected Cessna 320 aircraft, CASA assessed the directive and decided to cancel the Australian AD. This decision was made based on the conclusion that the unsafe condition addressed by the AD no longer exists. The cancellation of the AD became effective on 8 May 2008, and no replacement AD was required as the unsafe condition had been resolved. The process of cancelling the AD did not involve public consultation, as it was determined that ADs do not require a Regulatory Impact Statement.
In terms of legal consequences, the issuance and cancellation of ADs are governed by strict regulatory frameworks. Failure to comply with an AD can result in severe penalties. For civil aviation offences, the maximum penalties can include substantial fines and imprisonment. For example, under section 48 of the Civil Aviation Act 1988, a person who contravenes an AD can be fined up to $500,000 for a corporation and $100,000 for an individual, or face imprisonment for up to five years, or both. Such stringent measures underscore the importance of adhering to ADs to maintain safety in civil aviation. CASA's role in enforcing these regulations ensures that aircraft operating in Australian airspace meet the highest safety standards.
