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.
CASA issued AD/PA-23/27 affecting Piper PA-23 model aircraft in 1962. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been modified long ago.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that support these objectives, with a particular emphasis on airworthiness and safety. Under the authority granted by section 98 of the Act, the Civil Aviation Safety Regulations 1998 were subsequently created, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to mandate safety requirements for aircraft and aeronautical products. The issuance of ADs is a legislative instrument as defined by the Legislative Instruments Act 2003, and they play a crucial role in maintaining the continuing airworthiness of aircraft as per international standards set out in the Convention on International Civil Aviation.
In line with its responsibilities under the Civil Aviation Act 1988, CASA issued AD/PA-23/27 for Piper PA-23 model aircraft in 1962. Following a review, CASA has determined that this directive should be cancelled, effective from 3 July 2008, as all affected aircraft are believed to have been modified in accordance with the requirements long ago. The decision to cancel the AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, under subsection 84A(2) of the Act. The cancellation of this AD reduces the regulatory burden without necessitating a Regulatory Impact Statement or public consultation, as confirmed by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Safety Regulations 1998, made under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives, which are legislative instruments under the Acts Interpretation Act 1901 and Legislative Instruments Act 2003, serve to maintain the continuing airworthiness of aircraft and are recognised internationally under Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in Australia is CASA, must ensure compliance with these directives to uphold the safety standards for aircraft registered within its jurisdiction. The authority to issue these directives is exercised in accordance with subsection 84A(2) of the Act, and in the case of AD/PA-23/27 affecting Piper PA-23 model aircraft, CASA has decided to cancel the directive as it no longer applies due to the modifications already completed on the affected aircraft. This decision was made by the Manager, Airframes in the Airworthiness Engineering Branch, and is effective as of 3 July 2008. The cancellation of this AD is intended to reduce the regulatory burden without necessitating a Regulatory Impact Statement or public consultation, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, outlines the framework within which airworthiness directives (ADs) are issued and managed. Section 98 of the Act empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. This authority to issue ADs is further clarified by subregulation 39.001(5), which states that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are considered legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations require CASA to assess and, if appropriate, issue Australian ADs when a State of Design issues an AD against a type of aircraft registered in Australia. This ensures the continuing airworthiness of aircraft under Australian registry, aligning with Annex 8 to the Convention on International Civil Aviation. CASA, acting as the national airworthiness authority, must ensure that the requirements of ADs issued by the State of Design are appropriately mandated in Australia. In practical terms, this means that CASA must review any ADs from other countries and decide whether an Australian AD is necessary to enforce those requirements.
Breaching the requirements of an AD can lead to severe consequences. The Civil Aviation Act 1988 and associated regulations impose strict obligations on aircraft operators and other relevant parties to comply with ADs. Failure to adhere to an AD can result in civil penalties, including fines, and criminal charges for more serious violations. For instance, operating an aircraft in contravention of an AD can lead to fines of up to $132,000 for individuals and $660,000 for corporations, as well as potential imprisonment terms. These stringent measures underscore the importance of adhering to ADs to maintain the high safety standards expected in civil aviation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for the issuance and enforcement of ADs, ensuring the safety and airworthiness of aircraft. The obligations placed on CASA and other parties are critical in maintaining these standards, and the penalties for non-compliance are designed to enforce adherence to these safety requirements rigorously.
