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-28/8 affecting Piper PA-28 model aircraft in 1967. 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 inspected, and, if necessary, 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, enacted by the Commonwealth Parliament, was introduced to ensure the safety and efficiency of civil aviation in Australia. One of its key provisions is the authority for the Governor-General to make regulations under section 98, aimed at enhancing air navigation safety. The Civil Aviation Safety Regulations 1998 further delegate authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring that these directives comply with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs serve as critical instruments for maintaining the continuing airworthiness of aircraft, with the State of Design being responsible for providing necessary information, while the State of Registry enforces these requirements. CASA’s issuance and subsequent cancellation of AD/PA-28/8 for Piper PA-28 model aircraft, effective from 3 July 2008, demonstrates the practical application of these regulatory frameworks. This cancellation, determined by CASA to reduce the regulatory burden without necessitating public consultation or a Regulatory Impact Statement, underscores the authority and responsibility of CASA in regulating civil aviation in Australia.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, establishes a comprehensive framework for airworthiness directives (ADs) to ensure the safety of air navigation. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue ADs, which are legislative instruments, for specific types of aircraft or aeronautical products. These directives serve as a critical means for maintaining the continuing airworthiness of aircraft types and are integral to the responsibilities assigned to States of Design and States of Registry under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing ADs issued by States of Design and issuing corresponding Australian ADs as necessary. The Civil Aviation Safety Regulations 1998 also provide for the disallowance of ADs under section 46A of the Acts Interpretation Act 1901. In the instance of AD/PA-28/8 affecting Piper PA-28 model aircraft, CASA has determined to cancel this directive, effective from 3 July 2008, due to the historical nature of the issues it addressed and the likelihood that affected aircraft have already been inspected and modified. The decision to cancel this AD was made without public consultation as it reduces regulatory burden, and it has been determined that a Regulatory Impact Statement is not required for such actions.
Key Provisions
The Civil Aviation Act 1988, as amended, allows the Governor-General to make regulations for the safety of air navigation (s 98). One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This authority is vital for maintaining the safety and airworthiness of aircraft operating in Australia. ADs are considered legislative instruments under the Legislative Instruments Act 2003, reflecting their importance in the regulatory framework (reg 39.001(5)).
Under these provisions, CASA has the responsibility to issue ADs when necessary to ensure the continuing airworthiness of aircraft types registered in Australia. This aligns with the principles of Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the ongoing airworthiness of an aircraft type and requires it to provide necessary information to States of Registry. For Australia, this means that when an AD is issued by the State of Design, CASA must assess this information and, if appropriate, issue an Australian AD to enforce the State of Design's requirements.
In a specific instance, CASA issued AD/PA-28/8 in 1967 for Piper PA-28 model aircraft. After review, CASA decided to cancel this AD, effective from 3 July 2008. This decision was based on the assessment that all affected aircraft would have been inspected and modified long ago, rendering a replacement AD unnecessary. The cancellation of this AD reduces the regulatory burden, and no consultation with the Australian public was required as determined by the Office of Best Practice Regulation. Additionally, the Office determined that ADs do not necessitate a Regulatory Impact Statement. The cancellation was executed by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The issuance and cancellation of ADs carry significant implications for compliance and enforcement. Failure to comply with an AD can result in serious safety risks, leading to potential enforcement actions by CASA. Violations may incur civil penalties, including fines, and in severe cases, criminal charges, which could lead to imprisonment. The exact penalties depend on the nature and severity of the breach but are intended to ensure high standards of airworthiness and safety in the aviation sector.
