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/BEECH 90/1affecting Beechcraft 65-90 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 90/1. The cancellation will become effective on 03 July 2008. 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, addressing the need for a comprehensive and integrated system to ensure the safety, efficiency, and orderly development of civil aviation. The Act empowers the Governor-General to make regulations for the purposes of the Act, specifically in the interests of the safety of air navigation. One such regulation, the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. ADs serve as a critical tool for maintaining the continuing airworthiness of aircraft, aligning with international standards under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is tasked with assessing ADs issued by the State of Design and issuing corresponding Australian ADs as necessary, thereby fulfilling Australia's obligations under the Convention and ensuring compliance with international safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives, which are legislative instruments, are issued in relation to specific types of aircraft or aeronautical products and are designed to maintain the airworthiness of aircraft registered within Australia. The State of Design, typically the country where the aircraft is designed, has the overarching responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to the State of Registry. In Australia, CASA, as the national airworthiness authority, is responsible for assessing and issuing ADs based on information from the State of Design, ensuring that Australian regulations are met. The issuance and cancellation of ADs are governed by Australia’s commitments under the Convention on International Civil Aviation, and such legislative actions do not generally require public consultation or a Regulatory Impact Statement. This regulatory framework underscores Australia's commitment to maintaining high safety standards in civil aviation.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations for air navigation safety, with regulation 39.001 specifically allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft or aeronautical products. Section 39.001(5) of the Civil Aviation Safety Regulations 1998 classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus as legislative instruments under the Legislative Instruments Act 2003. These ADs are crucial for ensuring the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds primary responsibility for the airworthiness of an aircraft type. The State of Registry, in this case CASA, must ensure the continuing airworthiness of specific aircraft, often by issuing Australian ADs that mandate the requirements of the State of Design.
Under these regulations, the State of Design must provide necessary information to ensure the airworthiness of an aircraft type to the State of Registry, with ADs serving as the primary method of communication. When CASA issues an AD, it mandates compliance with specific safety requirements, thereby ensuring that the aircraft meets the necessary safety standards. The AD/BEECH 90/1, issued by CASA for Beechcraft 65-90 model aircraft, is an example of this process, where CASA cancelled the AD on 3 July 2008 after assessing that the unsafe condition no longer existed, without a need for a replacement AD.
The obligations placed on CASA and other parties under this Act are significant. CASA must assess any AD issued by the State of Design and determine whether an Australian AD is necessary. If an unsafe condition is identified, CASA must issue an AD to mandate the required safety measures. The State of Registry, including CASA, must ensure that aircraft comply with these directives to maintain airworthiness. Furthermore, the cancellation of an AD, as with AD/BEECH 90/1, must be assessed and confirmed by CASA to ensure that the aircraft type no longer poses a safety risk.
The consequences of breaching these regulations are severe. Failure to comply with an airworthiness directive can result in significant safety risks, potentially leading to accidents or incidents. Under the Civil Aviation Act 1988, CASA has the authority to enforce compliance, and any breach of an AD can result in civil or criminal penalties. For instance, individuals or companies found in breach of an AD may face fines or imprisonment, with the exact penalties depending on the severity and impact of the breach. CASA’s enforcement actions are critical to maintaining the high safety standards required in civil aviation.
