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/PA-31/11 affecting Piper PA-31 aircraft with aft-facing seats. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. The Act empowers the Governor-General to make regulations for air navigation safety, and under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives for aircraft and aeronautical products. These directives, considered legislative instruments, play a crucial role in maintaining the continuing airworthiness of aircraft in line with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Act 1988 aims to uphold the highest safety standards and align Australia's aviation practices with global norms, ensuring the safety of air navigation and the integrity of the aviation industry.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specified types of aircraft or aeronautical products. These directives are designed to ensure the continuing airworthiness of aircraft and are issued in accordance with Australia's obligations under the Convention on International Civil Aviation. The State of Registry of an individual aircraft, such as Australia through CASA, is responsible for ensuring the continuing airworthiness of the aircraft within its jurisdiction. The issuance of these directives is also subject to the provisions of the Acts Interpretation Act 1901, which designates them as disallowable instruments and, therefore, legislative instruments. The scope of these regulations extends to all aircraft and aeronautical products within Australia, with CASA acting on behalf of the State of Registry. This ensures compliance with international standards set by the International Civil Aviation Organization (ICAO). The application of these regulations is not limited by geographic boundaries within Australia but encompasses all aircraft registered within its territory. While the ADs are critical for ensuring safety and compliance, certain ADs may be subject to cancellation based on international obligations, as demonstrated by the cancellation of AD/PA-31/11 affecting Piper PA-31 aircraft with aft-facing seats, which was cancelled effective 31 July 2008.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for ensuring the safety and airworthiness of aircraft operating in Australia. Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in 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) for specific types of aircraft or aeronautical products. These directives, as outlined in subregulation 39.001(5), are considered disallowable instruments under the Acts Interpretation Act 1901 and thus, legislative instruments as per section 6 of the Legislative Instruments Act 2003. This regulatory structure ensures that safety measures are systematically implemented and enforced.
Under this legislative framework, the State of Design, which is typically the country where the aircraft is manufactured, has the primary responsibility for the continuing airworthiness of the aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Design must provide necessary information to ensure that the aircraft type remains airworthy. Conversely, the State of Registry, which is the country where the aircraft is registered, is responsible for the continuing airworthiness of the individual aircraft. This dual responsibility system ensures that both the design and operational aspects of aircraft safety are rigorously managed. The ADs issued by CASA serve as a key mechanism for communicating necessary safety information and requirements to the States of Registry and other stakeholders.
Compliance with airworthiness directives is mandatory for all parties governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Operators of affected aircraft must adhere to the directives issued by CASA to ensure their aircraft meet the required safety standards. These directives may include specific maintenance actions, inspections, or modifications necessary to maintain the aircraft's airworthiness. Failure to comply with these directives can lead to serious safety risks and legal consequences. CASA issues ADs based on thorough safety assessments and in accordance with international standards to ensure that the highest levels of safety are maintained.
Violations of the airworthiness directives or non-compliance with the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant legal and financial repercussions. The Act provides for various penalties for breaches, including fines and imprisonment for serious offences. The specific penalties depend on the nature and severity of the breach. For example, knowingly operating an aircraft that does not comply with an airworthiness directive could result in substantial fines and potential imprisonment. CASA enforces these regulations rigorously to uphold the safety standards required under Australian and international aviation laws.
