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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 400/59 affecting Cessna 401, 402, 404, 411, 414, 421 and 441 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 28 August 2008. No replacement AD is required.
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, 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 was enacted to provide a legal framework for the regulation of civil aviation in Australia. It empowers the Governor-General to make regulations for the safety of air navigation. Pursuant to section 98 of the Act, the Civil Aviation Safety Regulations 1998 were established to ensure the safe operation of aircraft, among other things. The Civil Aviation Safety Authority (CASA), under regulation 39.001 of these regulations, has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are legislative instruments subject to disallowance. These directives play a crucial role in maintaining the continuing airworthiness of aircraft, a responsibility that is ultimately held by the State of Registry under international conventions such as Annex 8 to the Convention on International Civil Aviation. This legislative framework ensures that the safety standards are aligned with international obligations and are implemented effectively within Australia.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under regulation 39.001 of these regulations, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve as a key mechanism for maintaining the continuing airworthiness of aircraft, aligning with international standards set by Annex 8 to the Convention on International Civil Aviation. The State of Design and the State of Registry both have responsibilities under this Convention, with the State of Registry ensuring the implementation of ADs for individual aircraft within its jurisdiction. The issuance and cancellation of these directives are internal to CASA, with the specific authority vested in the Manager, Airframes in the Airworthiness Engineering Branch. The cancellation of a particular AD, such as AD/CESSNA 400/59 affecting certain Cessna models, reflects Australia's adherence to international obligations and does not necessitate public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These directives are legislative instruments that serve to maintain the airworthiness of specific types of aircraft or aeronautical products. As per subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and in accordance with section 6 of the Legislative Instruments Act 2003, an AD is classified as a legislative instrument.
The obligations imposed by this legislation primarily rest on CASA, as the issuing authority, to ensure that ADs are issued when necessary to maintain the safety and airworthiness of aircraft. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to appropriate States of Registry. Similarly, the State of Registry, in this case, Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft as stipulated under Annex 8 to the Convention on International Civil Aviation. The specific AD/CESSNA 400/59, which affected Cessna 401, 402, 404, 411, 414, 421 and 441 model aircraft, was issued by CASA and subsequently reviewed and cancelled. This cancellation, which will become effective on 28 August 2008, is a result of Australia's obligations under the Convention on International Civil Aviation and does not require consultation with the Australian public or a Regulatory Impact Statement.
The consequences for non-compliance with airworthiness directives are significant. Failure to adhere to an AD can lead to serious safety issues and may result in enforcement actions by CASA. The Civil Aviation Safety Regulations 1998 and other relevant legislation may impose penalties, including fines and imprisonment, for breaches. The maximum penalties for non-compliance can vary depending on the nature and severity of the breach, but they are intended to ensure strict adherence to the safety standards set forth in the ADs. CASA has the authority to take enforcement actions, which may include grounding of aircraft, suspension of certificates, or other measures deemed necessary to ensure compliance and maintain safety standards in the aviation industry.
