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-25/33 Amdt 2 affecting Piper PA-25 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 20 November 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 and Structures 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 Australian Parliament, seeks to regulate civil aviation within Australia and to ensure the safety of air navigation. The Act allows the Governor-General to make regulations necessary for these purposes, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments that aim to maintain the continuing airworthiness of aircraft in line with international obligations under the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further empower CASA to issue these directives, which are considered crucial for ensuring that aircraft remain airworthy. In the case of AD/PA-25/33 Amdt 2 affecting Piper PA-25 aircraft, CASA has decided to cancel this directive due to Australia's obligations under the Convention, with the cancellation becoming effective on 20 November 2008. This cancellation does not require a replacement AD and was not subject to public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988 provides the framework for the regulation of civil aviation in Australia, with the Civil Aviation Safety Regulations 1998 detailing specific safety measures. Under this legislative framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products to ensure the safety of air navigation. ADs are legislative instruments as defined under the Legislative Instruments Act 2003, and they play a critical role in maintaining the continuing airworthiness of aircraft as required by Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the manufacturer's country, has the primary responsibility for ensuring the ongoing airworthiness of aircraft types, while the State of Registry, which in Australia is CASA, is responsible for the airworthiness of individual aircraft. This dual responsibility is reflected in the issuance and implementation of ADs, which CASA can issue and enforce within Australia's jurisdiction. In this specific instance, CASA issued AD/PA-25/33 Amdt 2 for Piper PA-25 aircraft, which has been subsequently cancelled in accordance with Australia's international obligations, demonstrating the interplay between national regulations and international civil aviation standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the regulation of civil aviation in Australia, with a particular emphasis on safety. Section 98 of the Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations that are in the interest of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 (regulation 39.001) specifies that the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as a legislative instrument (section 46A of the Acts Interpretation Act 1901, subregulation 39.001(5)) and are critical for maintaining the continuing airworthiness of aircraft.
The Act and Regulations impose several obligations on CASA, the State of Design, and the State of Registry. CASA is responsible for issuing ADs as required by regulation 39.001, ensuring compliance with Australia’s international obligations under the Convention on International Civil Aviation. The State of Design, as outlined in Annex 8, must provide necessary information to ensure the continuing airworthiness of an aircraft type and is responsible for the overall airworthiness of the aircraft. The State of Registry, also under Annex 8, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. These roles ensure a collaborative approach to maintaining airworthiness standards across different jurisdictions.
There are significant consequences for failing to comply with the provisions of the Act and Regulations. Under section 84A of the Civil Aviation Act 1988, CASA can impose civil penalties for non-compliance with ADs. The maximum penalty for contravening an AD can be substantial, reflecting the importance of adhering to safety regulations. The exact penalties are not detailed in the explanatory statement but are likely to be significant, given the potential impact of non-compliance on aviation safety. Additionally, failure to comply with international obligations under the Convention on International Civil Aviation may result in diplomatic repercussions and could affect Australia's standing in international aviation forums.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive regulatory framework for ensuring the safety of air navigation in Australia. CASA’s role in issuing ADs and the responsibilities of the State of Design and State of Registry are central to this framework. Compliance with these regulations is mandatory, and non-compliance can lead to severe civil penalties and international consequences.
