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 95/24 affecting Beechcraft 95, B95, B95A and E95 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 95/24. The cancellation will become effective on 31 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, Airframe and Structures, 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 by the Australian Parliament, addresses the overarching need to ensure the safety and efficiency of civil aviation in Australia. This legislation provides a legal framework for the regulation of civil aviation and the oversight of air navigation safety. It empowers the Governor-General to create regulations, including the issuance of airworthiness directives, for the safety of air navigation. In line with international standards, particularly those set by the Convention on International Civil Aviation, the Act delineates the responsibilities of States of Design and States of Registry in maintaining the continuing airworthiness of aircraft. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail the mechanisms for issuing and enforcing airworthiness directives. The policy objective of these regulations is to ensure that Australian aviation safety standards align with international benchmarks, thereby protecting public safety and fostering international cooperation in aviation safety management.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) under regulation 39.001, which empowers the Civil Aviation Safety Authority (CASA) to issue such directives concerning specific kinds of aircraft or aeronautical products. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are designed to ensure the continuing safety of air navigation as mandated by the Act. The ADs are issued in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation, where the State of Design is responsible for the airworthiness of an aircraft type, while the State of Registry, in this case CASA, is responsible for the airworthiness of individual aircraft registered in Australia. The application of these regulations extends to all aircraft and aeronautical products within Australia's jurisdiction, thereby affecting manufacturers, operators, and other entities involved in the aviation industry. The authority to issue, modify, or cancel ADs is exercised by CASA, reflecting Australia's commitment to international aviation safety standards and domestic regulatory requirements.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 establish the framework through which airworthiness directives (ADs) are issued and enforced. Under section 98 of the Act, the Governor-General has the authority to make regulations that serve the interests of air navigation safety. Regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular kinds of aircraft or aeronautical products, making these directives a legislative instrument as per the Legislative Instruments Act 2003. This regulatory framework ensures that any AD issued aligns with both national and international safety standards.
Entities governed by the Act, particularly CASA, have significant obligations. CASA must assess any AD issued by the State of Design and, if deemed appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards. The State of Registry of an individual aircraft is also responsible for ensuring the continuing airworthiness of that aircraft, which includes complying with ADs. CASA’s role is crucial in enforcing these directives to maintain safety across the Australian aviation sector.
Breaches of ADs can lead to serious consequences, both civil and criminal. Under the Civil Aviation Act 1988, non-compliance with ADs can result in penalties that include substantial fines and potential imprisonment. The exact penalties may vary depending on the severity and intent of the breach, but they are designed to enforce strict compliance with airworthiness directives to protect public safety. The enforcement of these regulations underscores the critical importance of adhering to ADs to maintain the high safety standards required in aviation.
The legislative framework, including the Civil Aviation Safety Regulations 1998 and the Convention on International Civil Aviation, ensures that ADs are issued and enforced in a manner that protects the safety of air navigation. By mandating that CASA assess and implement ADs from the State of Design, the legislation provides a robust system for managing airworthiness in Australia. The cancellation of AD/BEECH 95/24, for instance, demonstrates how the system adapts to changes in safety conditions, ensuring that only relevant and necessary directives are in effect. This continuous oversight is vital for maintaining the safety and reliability of Australia’s aviation sector.
