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-31/42 Amdt 2 affecting Piper PA-31-325 and PA-31P 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 to provide a comprehensive legal framework for civil aviation in Australia, includes provisions for ensuring the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under this Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that serve as legislative instruments to maintain the continuing airworthiness of aircraft and aeronautical products. These ADs, critical to upholding international standards set by the Convention on International Civil Aviation, are issued by CASA to address specific safety concerns. Recently, CASA reviewed and subsequently cancelled AD/PA-31/42 Amdt 2, which affected Piper PA-31-325 and PA-31P aircraft, due to Australia’s obligations under the Convention. This cancellation reflects CASA’s commitment to international safety standards and took effect on 31 July 2008, with no replacement AD deemed necessary. The legislative process for this cancellation was conducted in accordance with the statutory requirements of the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and oversight under the Legislative Instruments Act 2003. The Act applies to aircraft operators, manufacturers, and other entities involved in the aviation industry within Australia, ensuring compliance with both national and international airworthiness standards. The scope of the legislation extends to the maintenance and operation of aircraft within Australian jurisdiction, adhering to the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation, where the State of Design and the State of Registry play critical roles in the continuing airworthiness of aircraft. While the Act broadly covers all aircraft within its jurisdiction, specific ADs such as AD/PA-31/42 Amdt 2, which has been cancelled, target particular aircraft types and are issued to address specific safety concerns. The cancellation of this directive reflects Australia’s compliance with international aviation obligations and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to enact regulations aimed at enhancing the safety of air navigation. This legislative power allows for the creation of detailed safety standards and procedures necessary for the aviation industry. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are instrumental in maintaining the safety and airworthiness of aircraft by addressing potential hazards or safety issues. The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, which means they can be annulled if deemed inappropriate. Furthermore, under section 6 of the Legislative Instruments Act 2003, these directives are classified as legislative instruments, thus highlighting their formal and authoritative status.
The obligations and requirements imposed by these airworthiness directives are comprehensive and critical for ensuring the safety of aircraft. According to Annex 8 to the Convention on International Civil Aviation, the State of Design is tasked with the overarching responsibility of ensuring the continuing airworthiness of an aircraft type. This includes providing all necessary information to the States of Registry to maintain the airworthiness of the aircraft. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the individual aircraft under its jurisdiction. CASA, as the regulatory authority, issues ADs to implement these obligations. For instance, CASA issued AD/PA-31/42 Amdt 2 for Piper PA-31-325 and PA-31P aircraft, which has since been reviewed and cancelled, effective 31 July 2008, due to compliance with Australia’s international obligations under the Convention on International Civil Aviation.
Failure to comply with the requirements set out in airworthiness directives can result in significant consequences. The Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences or penalties for non-compliance with ADs, but non-compliance can lead to serious repercussions under broader aviation safety laws. In particular, if an aircraft is found to be operating without the necessary compliance with ADs, it could potentially face severe penalties, including fines or even grounding of the aircraft. Additionally, individuals or entities responsible for ensuring compliance may face legal action or sanctions. The safety and regulatory frameworks in place are designed to ensure that all parties involved in aviation adhere to stringent safety standards to prevent accidents and ensure the safety of passengers and crew.
Given the critical nature of airworthiness directives, the process for their creation and cancellation is closely monitored. For example, the cancellation of AD/PA-31/42 Amdt 2 by CASA was a direct result of Australia’s obligations under the Convention on International Civil Aviation. This cancellation did not require consultation with the Australian public, as determined by the Office of Best Practice Regulation, which found that such directives do not necessitate a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring that all regulatory actions are performed with due authority and oversight.
