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/LA-4/2 affecting Consolidated Aeronautics, Colonial LA-4 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/LA-4/2. The cancellation will become effective on 2 July 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, enacted by the Australian Parliament, provides the framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft registered in Australia. In accordance with this Act, the Civil Aviation Safety Regulations 1998 were established to further regulate aspects of civil aviation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as crucial tools for maintaining the safety standards of aircraft types on the Australian Register, aligning with Australia’s obligations under the Convention on International Civil Aviation. The cancellation of a specific AD for Consolidated Aeronautics, Colonial LA-4 series aeroplanes, as implemented by CASA, reflects the Authority’s commitment to upholding international safety standards and addressing any unsafe conditions identified. This legislative action underscores the importance of continuous oversight and the dynamic nature of aviation safety regulations in ensuring public protection and the integrity of the aviation industry.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation, particularly through the issuance of airworthiness directives (ADs). These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, thereby establishing requirements for maintaining the airworthiness of these aircraft. These ADs serve as a crucial tool in fulfilling Australia's obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, has the responsibility to ensure the ongoing airworthiness of aircraft registered in Australia. Therefore, when a State of Design issues an AD for a type of aircraft on the Australian Register, CASA must evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the required safety measures. The ADs are legislative instruments, subject to disallowance and scrutiny under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The specific AD/LA-4/2, issued by CASA and affecting Consolidated Aeronautics, Colonial LA-4 series aeroplanes, was cancelled due to the elimination of the unsafe condition, thus ending its requirement without the need for a replacement AD.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. This legislative power extends to the Civil Aviation Safety Regulations 1998, where regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, according to the Legislative Instruments Act 2003, they are legislative instruments.
These airworthiness directives are essential for maintaining the continuing airworthiness of aircraft, a responsibility that rests primarily with the State of Design, as per Annex 8 of the Convention on International Civil Aviation. The State of Design must provide necessary information to ensure the airworthiness of the aircraft type to all relevant States of Registry. In Australia, CASA, as the national airworthiness authority, evaluates the information provided by the State of Design and, if necessary, issues an Australian AD to enforce the safety requirements.
Entities governed by these regulations, including aircraft manufacturers and operators, are required to comply with ADs to ensure the safety of their aircraft. This involves adhering to specific maintenance, repair, and operational procedures as outlined in the directives. CASA's role includes monitoring compliance, conducting inspections, and taking enforcement actions if necessary. For example, in the case of Consolidated Aeronautics, Colonial LA-4 series aeroplanes, CASA issued and subsequently cancelled Australian AD/LA-4/2, reflecting Australia's commitment to international standards and the resolution of identified safety concerns.
Failure to comply with ADs can lead to significant legal consequences. Under the Civil Aviation Act 1988, non-compliance can result in substantial fines and imprisonment. Specifically, the maximum penalty for contravening an AD can be a fine of up to 120,000 penalty units or imprisonment for up to five years, or both. Such stringent penalties underscore the importance of adhering to airworthiness directives to ensure public safety and maintain the integrity of the aviation system.
