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.
CASA issued AD/BEECH 200/13 Amendment 1, affecting Beech 200 model aircraft in 1981. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes 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 the regulation and safety of civil aviation in Australia. It empowers the Governor-General to make regulations that ensure the safety of air navigation. One such regulation, established under the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This process aligns with international standards, particularly Annex 8 to the Convention on International Civil Aviation, which stipulates the responsibilities of the State of Design and the State of Registry in maintaining aircraft airworthiness. CASA issued an AD for the Beech 200 model aircraft in 1981; however, after reviewing the circumstances, CASA has decided to cancel this directive, effective from 10 April 2008. This cancellation reflects the resolution of the initial safety concerns, and no replacement AD is required. The decision to cancel the AD was made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the Act, without the need for public consultation or a Regulatory Impact Statement, as the cancellation alleviates regulatory burdens without compromising safety.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft within Australia. Under this Act, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs), which are legislative instruments aimed at maintaining the airworthiness of specific kinds of aircraft or aeronautical products. Such directives are crucial in addressing safety issues and ensuring that aircraft meet necessary safety standards. The ADs are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO) and are subject to the oversight of Australia's national airworthiness authority, CASA. These directives apply to aircraft registered in Australia and are particularly pertinent to aircraft manufacturers, operators, and maintenance providers, who must comply with the stipulated requirements to ensure the safe operation of aircraft. While the Act applies nationally, its scope extends to international standards, ensuring that Australian aviation safety measures are aligned with global best practices. Notably, the Act does not require public consultation for the cancellation of ADs if such cancellations result in a reduction of regulatory burden, as was the case with AD/BEECH 200/13 Amendment 1, which was cancelled effective 10 April 2008 due to the resolution of the original unsafe condition.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as related to airworthiness directives, are primarily found in section 98, which allows the Governor-General to make regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. Under subregulation 39.001(5), an AD is recognised as a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and thus classified as a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations and requirements imposed by these provisions include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type and to provide necessary information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of aircraft. For Australian-registered aircraft, CASA, as the national airworthiness authority, must assess information from the State of Design and, if necessary, issue an Australian AD to enforce the required safety measures. This regulatory framework is intended to ensure that all aircraft maintain a high standard of safety and airworthiness, aligning with international standards set out in Annex 8 to the Convention on International Civil Aviation.
Any breach of the provisions regarding airworthiness directives could lead to serious consequences. Although the Civil Aviation Act 1988 does not explicitly detail specific offences, penalties, or consequences for non-compliance with ADs, failure to adhere to such directives can result in the grounding of aircraft, revocation of airworthiness certificates, and other regulatory actions by CASA. These actions are taken to ensure that unsafe conditions identified by ADs are promptly addressed, thereby maintaining the safety of air navigation. The severity of the penalties and consequences for non-compliance can vary based on the extent and impact of the breach, with potential civil and criminal liabilities for individuals and entities found in violation of the regulations.
