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/PMC/12 Amendment 3 affecting McCauley propellers installed in rear position of Cessna 336 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/PMC/12 Amendment 3. The cancellation will become effective on 9 April 2009. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, is a comprehensive statute governing all aspects of civil aviation in Australia. Its primary purpose is to ensure the safety of air navigation and the continuing airworthiness of aircraft. The Act grants the Governor-General the authority to create regulations in the interests of safety, with the Civil Aviation Safety Regulations 1998 providing the framework for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives, which are legislative instruments subject to disallowance, are critical for maintaining the airworthiness of aircraft types, ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). The Act underscores the State of Design's responsibility for the continuing airworthiness of aircraft types and mandates that States of Registry, such as Australia through CASA, implement measures to uphold these standards. This legislative framework aims to protect public safety and uphold Australia's commitments under international aviation agreements.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. The Act empowers the Governor-General to make regulations concerning the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and the requirements of the Legislative Instruments Act 2003. The ADs are integral to ensuring the continuing airworthiness of aircraft, as per Annex 8 of the Convention on International Civil Aviation, which places responsibility on the State of Design for providing necessary information to States of Registry, including Australia. CASA, as Australia’s national airworthiness authority, must assess this information and issue corresponding ADs to mandate the required safety measures for aircraft registered in Australia. The authority to issue and cancel these directives is exercised by CASA, reflecting its role in upholding aviation safety standards in line with international obligations.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations that serve the interests of safety in air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, which means they hold the same legal status as other legislative documents, and can be disallowed under the Acts Interpretation Act 1901 (section 46A) and the Legislative Instruments Act 2003 (section 6). Essentially, ADs are formal documents that mandate safety requirements for aircraft to ensure they meet continuing airworthiness standards.
The obligations under these regulations place significant responsibility on both the State of Design and the State of Registry of an aircraft. The State of Design, typically the country where the aircraft is designed, is responsible for providing necessary information to ensure the aircraft’s continuing airworthiness. This is in accordance with Annex 8 to the Convention on International Civil Aviation. In turn, the State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure that the aircraft meets these airworthiness standards. In Australia, CASA acts as the national airworthiness authority, tasked with assessing information from the State of Design and issuing Australian ADs as necessary.
A practical example of this regulatory framework is seen in the case of AD/PMC/12 Amendment 3, which affected McCauley propellers installed in the rear position of Cessna 336 aircraft. CASA assessed this directive and subsequently cancelled Australian AD/PMC/12 Amendment 3, effective from 9 April 2009. This cancellation was due to the unsafe condition no longer existing, and no replacement AD was required. The cancellation process was conducted in line with Australia's obligations under the Convention on International Civil Aviation and did not require public consultation, as determined by the Office of Best Practice Regulation. Additionally, the AD was not subject to a Regulatory Impact Statement.
In terms of enforcement and compliance, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose stringent obligations on entities and individuals involved in civil aviation. Any failure to comply with these regulations, including the timely issuance or adherence to airworthiness directives, could result in significant legal consequences. The penalties for non-compliance can vary, but they typically include substantial fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, and they are designed to ensure the highest standards of safety and airworthiness are maintained within the aviation industry.
