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-22/5, affecting Piper PA-22 model aircraft, in the early 1950s. 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, addresses various aspects of civil aviation safety, including the issuance of airworthiness directives (ADs) to ensure the ongoing safety and airworthiness of aircraft. The Act provides the legislative framework under which the Civil Aviation Safety Regulations 1998 operate, and it allows the Civil Aviation Safety Authority (CASA) to issue ADs, which are legislative instruments that mandate compliance with specific safety requirements. The Civil Aviation Safety Regulations 1998 further specify the processes and responsibilities associated with ADs, including the alignment with international standards set by the Convention on International Civil Aviation. The objective of these provisions is to maintain and enhance the safety of air navigation by ensuring that aircraft remain in a condition that is safe for operation. CASA, as the national airworthiness authority, plays a critical role in assessing international ADs and issuing corresponding directives for aircraft registered in Australia, thereby fulfilling the obligations under international conventions and national legislation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. The ADs mandate the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, issues Australian ADs to implement the requirements set by the State of Design when such directives affect aircraft registered in Australia. For instance, CASA issued and subsequently cancelled AD/PA-22/5 for Piper PA-22 model aircraft, effective from 3 July 2008, without the need for public consultation or a Regulatory Impact Statement due to the minimal regulatory burden. The cancellation decision was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, in conjunction with 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. This authority is exercised under the overarching aim of ensuring the safety of air navigation as mandated by section 98 of the Civil Aviation Act 1988. An AD is a legislative instrument, as stipulated by subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, and it is a disallowable instrument according to section 46A of the Acts Interpretation Act 1901. Furthermore, as per section 6 of the Legislative Instruments Act 2003, an AD falls within the category of legislative instruments.
The obligations and requirements imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are primarily centred around the maintenance of airworthiness standards. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure compliance with safety standards. The State of Registry, on the other hand, is responsible for the ongoing airworthiness of individual aircraft. When an AD is issued by a State of Design, CASA, as Australia's national airworthiness authority, must assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that all aircraft registered in Australia conform to the necessary safety standards.
Breaches of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to various civil or criminal consequences. While the specific penalties for non-compliance are not detailed in the provided text, it is known that ADs are crucial for maintaining safety standards. Failure to adhere to an AD can result in severe consequences, including potential grounding of the aircraft, fines, or other regulatory actions. The exact penalties would depend on the severity of the breach and the specific regulations violated.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. The obligations and requirements of the Act and Regulations impose responsibilities on both the State of Design and the State of Registry to maintain airworthiness standards. Non-compliance with these provisions can lead to significant civil or criminal consequences, reinforcing the importance of adhering to the mandated safety standards.
