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 33/31 Amendment 1 affecting Beech 33 and 35-33 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 33/31 Amendment 1. The cancellation will become effective on 10 April 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 Acting 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 legal framework for civil aviation safety and efficiency in Australia. The Act empowers the Governor-General to make regulations for the purposes of the Act, particularly for the safety of air navigation, and it is under this authority that the Civil Aviation Safety Regulations 1998 were also established. One of the key objectives of these regulations is to ensure the continuing airworthiness of aircraft through the issuance of airworthiness directives (ADs). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. The ADs serve as a legislative instrument under the Legislative Instruments Act 2003 and are essential for compliance with the Convention on International Civil Aviation, particularly Annex 8, which places the responsibility of continuing airworthiness on the State of Design and the State of Registry. The Act and its regulations aim to harmonise Australia's civil aviation safety standards with international practices, ensuring the safe and efficient operation of aircraft within Australian airspace.
Scope and Application
The Civil Aviation Act 1988 and associated Civil Aviation Safety Regulations 1998 provide a comprehensive framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations in the interests of air navigation safety, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. An AD is considered a legislative instrument as per the Legislative Instruments Act 2003. The ADs serve as a mechanism for maintaining the continuing airworthiness of aircraft, a responsibility that falls to the State of Registry under Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is tasked with assessing information from the State of Design and issuing corresponding ADs as necessary to comply with international obligations and ensure the safety of aircraft registered in Australia. In this instance, CASA has cancelled Australian AD/BEECH 33/31 Amendment 1 for Beech 33 and 35-33 model aircraft due to the resolution of the unsafe condition it was intended to address, without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance and management of airworthiness directives (ADs) in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations to ensure the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. An AD is considered a legislative instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, which highlights its regulatory significance.
The obligations under this Act and its associated regulations place a primary responsibility on CASA as the national airworthiness authority to monitor and respond to ADs issued by the State of Design for aircraft types registered in Australia. Under Annex 8 to the Convention on International Civil Aviation, the State of Design must provide continuing airworthiness information, which CASA must then assess and, if necessary, implement as an Australian AD. This ensures that all aircraft registered in Australia meet the necessary safety standards.
Failing to comply with the requirements of an AD can lead to severe consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose stringent obligations on aircraft operators to adhere to ADs. Non-compliance can result in significant penalties, including fines and imprisonment, as outlined in the Act. For example, section 94 of the Act provides for civil penalties, while section 96 allows for criminal penalties for serious breaches. The specific penalties can vary depending on the nature and severity of the non-compliance, but they are intended to enforce strict adherence to airworthiness standards.
In the case of AD/BEECH 33/31 Amendment 1, CASA assessed the information provided by the State of Design and subsequently cancelled the AD because the unsafe condition it was addressing no longer existed. This cancellation became effective on 10 April 2008, and no replacement AD was required. This action underscores the importance of continuous monitoring and assessment to ensure that ADs remain relevant and necessary. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, simplifying the process for issuing and cancelling such directives.
