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-31/30 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, 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, enacted by the Australian Parliament, serves to regulate civil aviation within Australia, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations that align with the objectives of the Act, particularly focusing on the safety of air navigation. One such regulation, specified under the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs play a crucial role in maintaining the continuing airworthiness of aircraft, in line with Australia's international obligations under the Convention on International Civil Aviation. Recently, CASA issued a notice regarding the cancellation of AD/PA-31/30 affecting Piper PA-31 aircraft, effective from 31 July 2008, as a result of Australia's adherence to international aviation standards and without the need for public consultation or a Regulatory Impact Statement. This action was taken by the Manager, Airframes, in the Airworthiness Engineering Branch of CASA, as per the provisions of the Civil Aviation Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These directives are legislative instruments and are integral to ensuring the continuing airworthiness of aircraft as stipulated under Annex 8 to the Convention on International Civil Aviation. The ADs serve as the primary means through which the State of Design and the State of Registry communicate necessary information to maintain aircraft safety. CASA, acting on behalf of the Commonwealth, issues these directives to meet international standards and obligations, including those under the Convention. The scope of these directives applies to all relevant aircraft types and aeronautical products within Australia, encompassing both domestic and international operations. While the ADs are designed to enhance aviation safety, the cancellation of a specific AD, such as AD/PA-31/30 for Piper PA-31 aircraft, is determined by CASA based on international obligations, without necessitating public consultation or a Regulatory Impact Statement. The issuance and cancellation of these directives are thus critical to maintaining the safety and airworthiness of aircraft in accordance with both national and international regulatory frameworks.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. This act allows for the creation of regulatory frameworks that maintain the integrity and safety of aviation. Complementing this, 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. The ADs serve as formal mandates designed to ensure the safety and airworthiness of these aircraft, thereby safeguarding the interests of both operators and the public. Subregulation 39.001(5) further specifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and consequently, an AD is considered a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
Under the framework established by Annex 8 to the Convention on International Civil Aviation, the State of Design is tasked with the overall responsibility for the continuing airworthiness of an aircraft type. This entails ensuring that all necessary information is provided to the appropriate States of Registry to maintain the airworthiness of the aircraft. Similarly, the State of Registry bears the responsibility for the continuing airworthiness of individual aircraft, developing or adopting necessary requirements to meet these standards. The issuance of ADs is a prevalent method by which States communicate continuing airworthiness information, as mandated by ICAO Contracting States.
CASA, or its predecessors, had previously issued AD/PA-31/30 concerning Piper PA-31 aircraft. Following a review, CASA decided to cancel this directive, effective as of 31 July 2008, without the need for a replacement AD. This cancellation aligns with Australia's commitments under the Convention on International Civil Aviation, and thus, no consultation with the Australian public was required for this action. Additionally, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement. The AD was formally issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of obligations, CASA must ensure that ADs are issued and managed in compliance with international standards and national regulations, ensuring the safety and airworthiness of aircraft. The obligations imposed on aircraft operators include adhering to ADs, conducting required inspections and maintenance, and ensuring that aircraft remain in an airworthy condition. Failure to comply with ADs can lead to serious safety risks, resulting in severe consequences. Under the Civil Aviation Act 1988, breaches of ADs can result in civil penalties, including fines. The maximum penalty for non-compliance with an AD can be substantial, reflecting the critical nature of airworthiness directives in maintaining aviation safety standards.
