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 33/10 Amendment 1 affecting Beech 33 series aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 33/10 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 the safety and efficiency of civil aviation within Australia. This legislation empowers the Governor-General to create regulations that align with the Act's objectives, specifically to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Such ADs are considered legislative instruments under the Legislative Instruments Act 2003 and are subject to disallowance provisions in the Acts Interpretation Act 1901. The process of issuing ADs aligns with international standards set by the Convention on International Civil Aviation, where the State of Design is responsible for the continuing airworthiness of aircraft types, and the State of Registry must ensure the ongoing airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, evaluates ADs issued by other states and may issue corresponding Australian ADs if necessary.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives apply to specified kinds of aircraft or aeronautical products and are a legislative instrument as per the Legislative Instruments Act 2003. The authority to issue these directives stems from Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds the responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the continuing airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and issue Australian ADs as necessary. The AD/BEECH 33/10 Amendment 1, which affected Beech 33 series aircraft, was cancelled by CASA due to Australia's obligations under the Convention on International Civil Aviation, and the cancellation became effective on 10 April 2008. This cancellation was made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, under the authority granted by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 provides a framework for ensuring the safety of air navigation, and under section 98, the Governor-General has the authority to make regulations for this purpose. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is a legislative instrument as it is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and it is treated as such under section 6 of the Legislative Instruments Act 2003. ADs are crucial for maintaining the continuing airworthiness of aircraft, a responsibility that is shared between the State of Design and the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations under this legislation require CASA to assess any ADs issued by the State of Design concerning aircraft on the Australian Register. If deemed necessary, CASA must issue its own ADs to enforce the requirements of the State of Design, ensuring compliance with international safety standards. CASA must also ensure that any cancelled ADs, such as the recent cancellation of AD/BEECH 33/10 Amendment 1 for Beech 33 series aircraft, adhere to the obligations under the Convention on International Civil Aviation. This process ensures that all aircraft registered in Australia meet the necessary safety standards, even as these standards evolve.
In terms of penalties and consequences, breaches of ADs or failure to comply with mandated safety regulations can lead to significant civil and criminal liabilities. CASA has the authority to enforce compliance through administrative actions, which may include fines or other penalties as prescribed by the Civil Aviation Act 1988 and related regulations. Non-compliance with airworthiness directives can also result in the grounding of aircraft, which could further lead to severe operational disruptions and safety risks. Furthermore, under the Convention on International Civil Aviation, non-compliance may result in international sanctions or restrictions on air travel, impacting both individuals and corporations.
The Civil Aviation Act 1988 and its associated regulations ensure that all parties involved in the aviation industry, from manufacturers to operators, adhere to stringent safety standards. By issuing and enforcing ADs, CASA plays a critical role in maintaining the safety of air navigation within Australia, aligning with both national and international obligations.
