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-31/49 affecting Piper PA-31T 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 was enacted to ensure the safety of air navigation in Australia, with the overarching aim of protecting the public and promoting the safe and efficient use of airspace. This Act empowers the Governor-General to make regulations that support its objectives, as seen in the Civil Aviation Safety Regulations 1998. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives, which are legislative instruments that serve to maintain the continuing airworthiness of aircraft and aeronautical products, thereby contributing to aviation safety. The Civil Aviation Act 1988 and its associated regulations work in conjunction with international standards, such as those set forth in Annex 8 to the Convention on International Civil Aviation, to ensure that Australia meets its obligations in maintaining international safety standards. The cancellation of an airworthiness directive for Piper PA-31T aircraft, as announced by CASA, demonstrates the dynamic nature of aviation safety regulation, where international obligations and national safety considerations must be balanced.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, with these directives being considered disallowable instruments under the Acts Interpretation Act 1901. This regulatory framework is designed to ensure the safety of air navigation in accordance with section 98 of the Civil Aviation Act 1988. The scope of these ADs applies to any aircraft or aeronautical products that CASA determines require such directives to maintain airworthiness. These regulations are applicable nationally, extending across the Commonwealth of Australia, and align with international standards set out in Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry share responsibilities for ensuring aircraft airworthiness. The ADs are issued to address specific safety concerns and are tailored to particular types of aircraft, ensuring compliance with both national and international safety standards. The application of these directives does not require public consultation due to their alignment with international conventions, and they do not necessitate a Regulatory Impact Statement. CASA issues these directives under the authority granted by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to make regulations in the interest of air navigation safety. This authority is exercised through the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are formal regulatory instruments that must comply with the Legislative Instruments Act 2003, as they are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. This legislative framework ensures that ADs are issued in accordance with Australia's international obligations under the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, ADs play a crucial role in maintaining the continuing airworthiness of aircraft. The State of Design, which is the country where the aircraft is designed, has the primary responsibility for ensuring the continuing airworthiness of the aircraft type, and must provide necessary information to the States of Registry. Meanwhile, the State of Registry, in this case Australia, must develop or adopt its own requirements to ensure that individual aircraft remain airworthy. CASA, as the regulatory authority, issues these directives to comply with these obligations, thereby ensuring that aircraft operating in Australian airspace meet safety standards.
The obligations imposed on parties governed by the Civil Aviation Safety Regulations 1998 include adherence to ADs issued by CASA. These directives may require aircraft owners or operators to perform specific maintenance actions, inspections, or modifications to ensure that the aircraft remains airworthy. Non-compliance with an AD can result in the aircraft being deemed unairworthy, which can lead to serious safety risks. Therefore, aircraft owners and operators must stay informed about relevant ADs and ensure that all mandated actions are completed within the specified timeframes. CASA also has the responsibility of monitoring compliance with these directives to maintain safety standards.
Breach of the requirements set out in an AD can lead to significant consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can result in enforcement actions by CASA. This may include administrative penalties, fines, and in severe cases, the grounding of the aircraft. The maximum penalties for non-compliance with ADs can vary, but they are designed to ensure that safety is not compromised. The seriousness of the consequences underscores the importance of adhering to ADs to maintain the safety of air navigation in Australia.
