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/BEECH 95/14 affecting Beechcraft 95 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 95/14. The cancellation will become effective on 31 July 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, Airframe and Structures, 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, establishes the legal framework for the regulation of civil aviation in Australia, with a strong emphasis on safety and efficiency. This Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, thereby filling a critical gap in the oversight of civil aviation activities. One key provision under the Act is the ability for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which align with international standards set by the International Civil Aviation Organization (ICAO). These ADs are legislative instruments subject to disallowance and are issued to maintain the continuing airworthiness of aircraft, ensuring they meet safety standards both domestically and internationally. The objective of these regulations is to uphold the safety and reliability of aircraft within Australia, in line with international obligations and standards.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft registered in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specified kinds of aircraft or aeronautical products, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The application of these ADs is in line with Australia’s obligations under Annex 8 of the Convention on International Civil Aviation, where the State of Design is responsible for providing necessary information to ensure the continuing airworthiness of aircraft types, and the State of Registry, such as Australia, must implement these directives to mandate specific requirements. CASA's role includes assessing information from the State of Design and issuing Australian ADs to comply with international standards, as demonstrated in the cancellation of AD/BEECH 95/14 for Beechcraft 95 model aircraft, effective from 31 July 2008, due to the resolution of the unsafe condition. This process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act (1), the Governor-General can make regulations to ensure safety. Regulation 39.001 of the Regulations (2) allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (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 the Acts Interpretation Act 1901 (3).
The obligations imposed by these provisions require CASA to assess airworthiness directives issued by the State of Design (the country where the aircraft type is designed) and determine whether an Australian AD is necessary. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and it must provide necessary information to the States of Registry (where the individual aircraft is registered) to ensure ongoing airworthiness (4). In Australia, CASA is the national airworthiness authority and must evaluate the ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to mandate specific requirements (5).
Failure to comply with airworthiness directives can lead to serious safety issues, potentially resulting in accidents or incidents. While specific penalties for non-compliance with ADs are not detailed in the Act or Regulations, the overarching framework implies that non-compliance could lead to significant civil or criminal consequences. This might include actions such as grounding of aircraft, fines, or other enforcement measures taken by CASA to ensure compliance and maintain safety standards.
The cancellation of AD/BEECH 95/14, affecting Beechcraft 95 model aircraft, exemplifies the process by which CASA assesses and potentially cancels ADs when the unsafe condition no longer exists. This cancellation was made in accordance with the legislative framework and Australia’s obligations under the Convention on International Civil Aviation, which does not require public consultation or a Regulatory Impact Statement for such actions (6). The cancellation took effect on 31 July 2008, and no replacement AD was necessary as the unsafe condition had been resolved.
