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-31/52 affecting Piper PA-31 aircraft. 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, Systems and New Technologies 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 regulate civil aviation in Australia, establishing a framework for ensuring the safety and efficiency of air navigation. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives, which are legislative instruments, are designed to maintain the airworthiness of aircraft and aeronautical products. In line with international standards under Annex 8 of the Convention on International Civil Aviation, the State of Design has the responsibility for the continuing airworthiness of aircraft types, while the State of Registry ensures the airworthiness of individual aircraft. The Civil Aviation Safety Regulations 1998 also specify that ADs are disallowable instruments, subject to the Acts Interpretation Act 1901. Recently, CASA reviewed and subsequently cancelled AD/PA-31/52 for Piper PA-31 aircraft, a decision effective from 31 July 2008, in accordance with Australia’s obligations under the Convention on International Civil Aviation. This cancellation did not require consultation with the public or a Regulatory Impact Statement, and was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. According to section 98 of the Act, the Governor-General has the authority to make regulations that serve 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 ADs for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and are subject to disallowance, as outlined in section 6 of the Legislative Instruments Act 2003. The ADs are integral to ensuring the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry bear responsibility for maintaining airworthiness. The AD/PA-31/52, issued by CASA concerning Piper PA-31 aircraft, has been cancelled due to Australia's obligations under the Convention on International Civil Aviation, and no replacement AD is deemed necessary. The cancellation of this AD did not require public consultation or a Regulatory Impact Statement, and it will become effective on 31 July 2008.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, outlines the framework under which airworthiness directives (ADs) are issued and managed in Australia. Section 98 of the Act allows the Governor-General to create regulations aimed at ensuring the safety of air navigation, while regulation 39.001 of the 1998 Regulations specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. This regulatory power is further clarified under subregulation 39.001(5), which indicates that ADs are disallowable instruments and thus fall under the purview of the Legislative Instruments Act 2003. These ADs serve as a crucial mechanism for maintaining the airworthiness of aircraft types, in alignment with Annex 8 of the Convention on International Civil Aviation, which stipulates that the State of Design is responsible for the ongoing airworthiness of an aircraft type.
The obligations under the Act and Regulations primarily rest on CASA to ensure that ADs are issued and managed in accordance with international standards and obligations. CASA, in its role as the regulatory authority, must review and, if necessary, cancel existing ADs, as evidenced by the recent cancellation of AD/PA-31/52 affecting Piper PA-31 aircraft. This cancellation, effective from 31 July 2008, was made without public consultation, as per the Office of Best Practice Regulation's determination that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in compliance with subsection 84A(2) of the Act.
Failure to comply with ADs can have significant legal implications. While the specific penalties for non-compliance are not detailed in the provided text, it is understood that non-compliance with airworthiness directives could lead to both civil and criminal consequences, depending on the severity and intent behind the breach. The overarching goal is to maintain the highest standards of safety in air navigation, ensuring that aircraft meet the necessary airworthiness criteria as mandated by both national and international regulations. This is crucial for protecting the safety of passengers, crew, and the general public.
