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 US FAA issued AD 2007-25-03, affecting Boeing B737 model aircraft, in 2007. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to clarify the applicability. The amended AD, AD/B737/312 Amendment 1, will become effective on 01 February 2008. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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, Airframes 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation within the country. This Act empowers the Governor-General to make regulations that contribute to the safety of air navigation, which is crucial for maintaining high standards in the aviation industry. In line with this objective, the Civil Aviation Safety Regulations 1998 were established to further detail the requirements and processes necessary to ensure the safety and airworthiness of aircraft. Specifically, regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, with such directives being considered legislative instruments under the Legislative Instruments Act 2003. This legislative framework ensures that Australia adheres to international standards, as outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, applies to all aviation-related activities and entities within Australia, ensuring that these are conducted in a manner that prioritises safety. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. These directives are legislative instruments and serve as a means to mandate safety requirements. The ADs are issued under the overarching responsibility of the State of Design, which in the case of Australia is CASA, ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. When an AD is issued by another State of Design, such as the United States for Boeing B737 models, CASA is obliged to review and, if necessary, issue an equivalent AD for Australian-registered aircraft. The ADs do not undergo public consultation or require a Regulatory Impact Statement, reflecting their technical nature and the reliance on international safety standards. This regulatory framework ensures that all aviation activities within Australia adhere to stringent safety protocols.
Key Provisions
The primary operative sections of the Civil Aviation Safety Regulations 1998, as referenced in regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This regulatory power is exercised under section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations for the safety of air navigation. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003, and are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. Essentially, an AD is a formal instruction issued to ensure the continuing airworthiness of aircraft, which is critical for maintaining safety standards in aviation.
The obligations imposed by these regulations on the parties and entities governed include adherence to the ADs issued by CASA. As the national airworthiness authority, CASA must assess information provided by the State of Design, such as the United States Federal Aviation Administration (FAA) in the case of the Boeing B737, and if necessary, issue an Australian AD to enforce the required safety measures. The State of Registry, which in this context is Australia, is responsible for ensuring the continuing airworthiness of aircraft registered within its territory. This includes implementing and complying with ADs, ensuring that aircraft meet all stipulated safety standards.
Non-compliance with the ADs or failure to implement the required safety measures can lead to severe consequences. The Civil Aviation Safety Regulations 1998, although not explicitly detailing specific offences or penalties in the provided text, typically outline that breaches of airworthiness directives can result in both civil and criminal penalties. The severity of these penalties can vary, but they often include fines, potential grounding of non-compliant aircraft, and in more severe cases, prosecution leading to imprisonment. The exact penalties are not detailed in the provided excerpt but are governed by the broader civil aviation laws and regulations.
