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.
The Civil Aviation Safety Authority or its predecessors issued AD/PNEU/2 affecting Dunlop Air Bottles. CASA has assessed this AD and as a result has cancelled Australian AD/PNEU/2. The cancellation will become effective on 9 April 2009. No replacement AD is required, as the unsafe condition no longer exists.
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, Systems and New Technologies, 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 provide a comprehensive legal framework for the regulation of civil aviation in Australia, with a focus on ensuring the safety of air navigation. Under this Act, the Governor-General is empowered to create regulations that serve the interests of aviation safety. One such regulation is the issuance of airworthiness directives, which fall under the purview of the Civil Aviation Safety Regulations 1998. These airworthiness directives are legislative instruments that mandate requirements for the continuing airworthiness of aircraft, ensuring that they meet the necessary safety standards. The Civil Aviation Safety Authority (CASA) plays a crucial role in this regulatory process by issuing these directives when required, and in alignment with Australia’s international obligations under the Convention on International Civil Aviation. The policy objective behind these regulations is to maintain the highest standards of aviation safety by enforcing stringent airworthiness requirements.
Scope and Application
The Civil Aviation Act 1988 and its accompanying regulations, including the Civil Aviation Safety Regulations 1998, pertain to the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act, which includes the issuance of airworthiness directives (ADs) under regulation 39.001. These directives are legislative instruments that apply to specific kinds of aircraft or aeronautical products, and are made in accordance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority and is responsible for assessing and issuing ADs when necessary to ensure the continuing airworthiness of aircraft registered in Australia. The scope of the ADs extends to all aircraft or aeronautical products within the Australian jurisdiction, with CASA ensuring compliance with both national and international safety standards. Exclusions and exemptions from the application of these regulations are not specified in the provided text, but the ADs themselves are tailored to specific aircraft or products, thereby applying only to those identified as requiring safety measures. The ADs can be further extended or restricted through subordinate instruments, aligning with Australia's obligations under international conventions and agreements.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to make regulations, including ADs, for the purpose of ensuring the safety of air navigation. Regulation 39.001 allows CASA to issue ADs for specific types of aircraft or aeronautical products. These ADs, as stated in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments under the Legislative Instruments Act 2003.
Under these regulations, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. This responsibility includes providing necessary information to ensure the continuing airworthiness of the aircraft type to the States of Registry. The State of Registry, on the other hand, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA must assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
In the specific case of Dunlop Air Bottles, CASA has issued and subsequently cancelled Australian AD/PNEU/2. This cancellation took place due to Australia's obligations under the Convention on International Civil Aviation, which led to the conclusion that the unsafe condition no longer existed. Consequently, no replacement AD is required. The cancellation process did not involve public consultation as it was determined by the Office of Best Practice Regulation that ADs do not require a Regulatory Impact Statement. The AD cancellation was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The implications of breaching the requirements set out in these regulations can be significant. Non-compliance with ADs can lead to severe consequences, including potential grounding of aircraft, which can result in operational disruptions and safety risks. Civil and criminal penalties may apply, depending on the severity of the breach and the specific provisions of the Act. In some cases, individuals or entities may face fines, imprisonment, or both, as stipulated by the Civil Aviation Act 1988 and related regulations. The specific penalties can vary, but they are designed to ensure adherence to safety standards and protect public safety in the aviation sector.
