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 United States FAA has issued AD 80-09-05 affecting Boeing 737 100 and 200 series aeroplanes. The United States is the State of Design for these aeroplanes. CASA has assessed this AD and has issued Australian AD/B737/306, which will become effective on 30 August 2007.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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 regulation of civil aviation in Australia, ensuring safety and efficiency in the sector. Under the authority conferred by section 98 of the Act, the Governor-General can make regulations for the purposes of the Act, with a specific focus on the safety of air navigation. The Civil Aviation Safety Regulations 1998, which were also enacted to support the Act, include provisions for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA) in relation to certain kinds of aircraft or aeronautical products. These directives are essential tools for maintaining the continuing airworthiness of aircraft, aligning with international standards and obligations under the Convention on International Civil Aviation. The issuance of such directives is a legislative instrument and does not require public consultation or a Regulatory Impact Statement, as it is based on international obligations and assessments by CASA.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, applies to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations empower CASA to issue ADs for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. An AD is considered a disallowable instrument under the Acts Interpretation Act 1901, making it a legislative instrument in accordance with the Legislative Instruments Act 2003. The ADs are typically issued in response to obligations under the Convention on International Civil Aviation, where the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type. The State of Registry, which in Australia is CASA, must ensure that the aircraft within its jurisdiction meet continuing airworthiness requirements. This includes assessing and, if necessary, issuing Australian ADs in response to ADs issued by the State of Design. The geographic reach of this legislation is national, applying across Australia as CASA acts as the country's airworthiness authority. The issuance of ADs does not generally require public consultation or a Regulatory Impact Statement, as they are typically responses to international obligations and are directly related to maintaining aviation safety standards.
Key Provisions
The Civil Aviation Safety Regulations 1998 under section 39.001 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified kinds of aircraft or aeronautical products. These ADs are legislative instruments as per the Legislative Instruments Act 2003 and are intended to ensure the safety of air navigation, aligning with the overarching principles of the Civil Aviation Act 1988. An AD mandates specific actions or checks that must be performed on an aircraft or aeronautical product to maintain its airworthiness. These directives are issued in response to identified safety issues or necessary modifications to ensure the continued safe operation of the aircraft.
The obligations imposed by the Act and the accompanying regulations on parties governed by these provisions are substantial. For instance, the State of Design, such as the United States in the case of Boeing 737 100 and 200 series aeroplanes, must provide necessary information to maintain the airworthiness of the aircraft type. CASA, as Australia's national airworthiness authority, has the obligation to assess the information provided by the State of Design and, if necessary, issue corresponding ADs that apply to aircraft registered in Australia. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must ensure compliance with the ADs issued by CASA. This involves implementing the required modifications or checks as stipulated in the ADs to maintain the safety standards set by international and national regulations.
Breaching the requirements outlined in an airworthiness directive can have serious legal consequences. Although the specific offences and penalties are not detailed in the provided text, it is understood that failure to comply with an AD can result in significant civil or criminal penalties. In the broader context of the Civil Aviation Act 1988, non-compliance with safety regulations can lead to substantial fines, aircraft grounding, or even criminal charges against individuals or corporations responsible for the oversight of the aircraft. The severity of the penalties reflects the critical nature of air safety and the high stakes involved in the operation of civil aircraft.
