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-23/41 affecting Piper PA-23 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 12 February 2009. 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 acting Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive regulatory framework for ensuring the safety of civil aviation in Australia. This Act empowers the Governor-General to make regulations in the interests of air navigation safety, delegating authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs serve as legislative instruments in accordance with the Legislative Instruments Act 2003, reflecting Australia's commitment to international standards set by the International Civil Aviation Organization (ICAO). Specifically, the Act addresses the need for a robust system to ensure the continuing airworthiness of aircraft, aligning with the responsibilities of the State of Design and the State of Registry under Annex 8 to the Convention on International Civil Aviation. The recent cancellation of AD/PA-23/41, which affected Piper PA-23 aircraft, exemplifies CASA's responsiveness to international obligations, thereby demonstrating the dynamic nature of aviation safety regulation.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, which are subsidiary legislation of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments and fall under the purview of the Legislative Instruments Act 2003. The issuance of these directives is guided by Annex 8 of the Convention on International Civil Aviation, which places the responsibility of ensuring the continuing airworthiness of aircraft with the State of Registry, which in this case is Australia. CASA, acting on behalf of the Commonwealth, thus exercises its regulatory authority within the parameters set by international standards and agreements. The scope of these regulations extends to all aircraft registered within Australia, encompassing both commercial and private entities operating such aircraft. The application of these regulations is not limited by geographic boundaries within Australia but adheres to the international obligations of the Convention on International Civil Aviation. There are no stated exclusions or exemptions within the text, although the practical application may vary depending on specific circumstances of aircraft operation and design. The legislative process for ADs includes the possibility of their disallowance under the Acts Interpretation Act 1901, further illustrating the regulatory framework's integration with broader legislative principles.
Key Provisions
The primary operative sections relevant to the Civil Aviation Safety Regulations 1998 pertain to the issuance of airworthiness directives (ADs) under section 39.001. This regulation empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, ensuring that these vehicles meet the required safety standards. As detailed in subregulation 39.001(5), an AD is recognised as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and it is considered a legislative instrument according to section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that ADs are issued with the authority and oversight necessary to maintain the highest safety standards in civil aviation.
The obligations imposed by the Act and the regulations are significant for both CASA and the entities it governs. CASA must ensure that ADs are issued based on rigorous safety assessments and are aligned with international standards as stipulated by the Convention on International Civil Aviation, particularly Annex 8. This Annex mandates that the State of Design (typically the country where the aircraft was designed) must provide necessary information to ensure the continuing airworthiness of an aircraft type. Similarly, the State of Registry (the country where the aircraft is registered) must develop or adopt requirements to ensure that individual aircraft remain airworthy. These obligations ensure that all stakeholders are committed to maintaining the safety and airworthiness of aircraft within their jurisdictions.
There are no direct references to specific offences, penalties, or consequences for breaching these regulations within the provided text. However, the stringent nature of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 implies that non-compliance with ADs could lead to serious consequences. Failure to adhere to ADs could result in the grounding of aircraft, legal action against individuals or companies responsible for the non-compliance, and potentially severe penalties under broader aviation safety laws. The overarching aim is to ensure that all parties involved in civil aviation comply with safety directives to prevent accidents and ensure public safety.
