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 has issued AD 2002-11-05 R1 affecting Airtractor AT500 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT/20, Amendment 4, which will become effective on 5 May 2006. 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the industry. As a key piece of legislation, it empowers the Governor-General to make regulations that safeguard air navigation, with the overarching goal of protecting public safety. In accordance with this Act, the Civil Aviation Safety Regulations 1998 were established to further detail safety standards and requirements, including the issuance of airworthiness directives (ADs). ADs are legislative instruments issued by the Civil Aviation Safety Authority (CASA) to mandate the continuing airworthiness of aircraft, ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). This regulatory approach is crucial in addressing the problem of maintaining consistent safety standards across the aviation industry, particularly when corresponding to directives issued by the State of Design of an aircraft type, such as the recent Australian AD/AT/20, Amendment 4, which aligns with an AD issued by the US Federal Aviation Administration.
Scope and Application
The Civil Aviation Safety Regulations 1998, which fall under the purview of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that mandate safety standards and procedures to ensure the continuing airworthiness of aircraft registered in Australia. The State of Design, such as the United States in the case of the Airtractor AT500 model aircraft, has the primary responsibility to issue ADs for aircraft types it designs, and the State of Registry, which for Australian-registered aircraft is CASA, must adopt these ADs to maintain compliance with international standards. In this specific instance, CASA has issued Australian AD/AT/20, Amendment 4, effective from 5 May 2006, to address the requirements outlined in the US FAA’s AD 2002-11-05 R1. This action is in accordance with Australia’s obligations under the Convention on International Civil Aviation and is executed without public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The issuance of this AD is managed by the Manager, Airframes within CASA’s Manufacturing, Certification and New Technologies Office, pursuant to the provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation. According to section 98 of the Act, the Governor-General has the authority to make regulations for the Act's purposes, particularly to enhance air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. It is crucial to note that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, as such, are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by this legislation are multifaceted and centre around ensuring the continuing airworthiness of aircraft. The State of Design, which in this case is the United States for the Airtractor AT500 model aircraft, holds the primary responsibility for the type's airworthiness, including providing necessary information to States of Registry. The State of Registry, which for Australian-registered aircraft is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design, such as the US, issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to enforce the State of Design's requirements.
Breaching the requirements outlined in an AD can have significant legal and safety consequences. The Civil Aviation Act 1988 and associated regulations establish penalties for non-compliance with ADs. While specific penalties are not detailed in the provided text, it is understood that failure to adhere to these directives can result in severe civil or criminal consequences, including fines and imprisonment. The exact penalties would be in accordance with the broader legal framework governing civil aviation in Australia. These stringent measures underscore the importance of compliance to ensure the highest standards of air safety.
