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-23/47, affecting Piper PA-23 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
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, enacted by the Commonwealth Parliament, was introduced to address the need for a robust legal framework to ensure the safety and efficiency of civil aviation within Australia. This legislation empowers the Governor-General to make regulations in the interest of air navigation safety, delegating authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments designed to ensure the continuing airworthiness of aircraft, aligning with international standards set out in Annex 8 to the Convention on International Civil Aviation. The policy objective underpinning the Act is to maintain the highest standards of safety in civil aviation, ensuring both domestic and international compliance with safety protocols.
CASA issued Airworthiness Directive AD/PA-23/47 in 1971, affecting Piper PA-23 model aircraft, but has decided to cancel it, effective from 17 January 2008. This decision was made after reviewing the directive and determining that the original unsafe condition it addressed is now covered by AD/GENERAL/74 Amendment 1. The cancellation of this directive reduces the regulatory burden, and no consultation with the public was deemed necessary. The Office of Best Practice Regulation has concluded that such airworthiness directives do not require a Regulatory Impact Statement. The cancellation was executed by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the provisions of the Civil Aviation Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, mandate requirements for maintaining the airworthiness of aircraft registered in Australia. The Civil Aviation Act 1988 provides the legislative foundation for CASA’s regulatory actions, enabling the authority to issue, amend, or cancel ADs as necessary to address safety concerns. These directives apply to aircraft operators, owners, and manufacturers who must comply with the specified safety requirements. Although no public consultation was undertaken for the cancellation of AD/PA-23/47 due to its minimal regulatory impact, all ADs must align with the continuing airworthiness responsibilities outlined in Annex 8 of the Convention on International Civil Aviation. The cancellation of this particular AD is effective from 17 January 2008, with no replacement directive needed as the safety issue it addressed is now covered by another AD.
Key Provisions
The main operative sections of this legislation are section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments as per section 6 of the Legislative Instruments Act 2003. ADs serve as the primary means of ensuring the continuing airworthiness of aircraft types as outlined in Annex 8 to the Convention on International Civil Aviation. In particular, the State of Design is responsible for providing necessary information to ensure the airworthiness of aircraft types, while the State of Registry must implement the requirements of any ADs issued.
The obligations imposed by this Act on CASA include the responsibility to review and, if necessary, issue Australian ADs based on the information provided by the State of Design. This obligation ensures that all aircraft registered in Australia meet the necessary safety standards. CASA must also assess any ADs issued by other countries and decide whether an Australian AD is required. This process involves a detailed evaluation to ensure that the ADs align with Australian safety standards and regulatory requirements. Furthermore, CASA must ensure that any ADs issued are communicated effectively to the relevant stakeholders, including aircraft owners and operators, to ensure compliance.
The legislation also addresses the consequences of non-compliance with ADs. While the specific penalties for non-compliance with ADs are not detailed in the provided text, it is clear that failure to comply with an AD could result in serious safety issues and potential legal consequences. The severity of the penalties would depend on the nature and impact of the non-compliance. In general, non-compliance with aviation safety regulations can result in significant fines, legal action, and potential grounding of aircraft, which could lead to criminal charges in cases of gross negligence or willful disregard for safety regulations. The safety of air navigation is paramount, and any breaches of ADs could have severe ramifications, including endangering lives and property.
