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.
Transport Canada has issued AD CF-2002-03R2 affecting Bell 427 helicopters. Canada is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/BELL 427/3, which will become effective on 11 May 2006.
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, 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 comprehensive legislative framework for civil aviation in Australia, addressing gaps in the regulation of air safety, air navigation, and the oversight of air carriers. This Act empowers the Governor-General to make regulations for air safety and navigation in the interests of public safety, and it designates the Civil Aviation Safety Authority (CASA) as the national authority responsible for enforcing and regulating civil aviation safety standards. One key mechanism through which CASA exercises its regulatory powers is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives serve as legislative instruments, mandated by Australia’s obligations under the Convention on International Civil Aviation, to ensure the continuing airworthiness of aircraft and aeronautical products. In response to an AD issued by Canada concerning Bell 427 helicopters, CASA has issued its own Australian AD/BELL 427/3, reflecting its duty to enforce safety standards derived from international obligations and the relevant State of Design.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 39.001, authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) pertaining to specific types of aircraft or aeronautical products. These ADs are integral to ensuring the safety and airworthiness of aircraft registered in Australia, aligning with the overarching responsibility of the State of Registry as stipulated in Annex 8 to the Convention on International Civil Aviation. The issuance of ADs is typically in response to safety concerns identified by the State of Design, which in this case is Canada for the Bell 427 helicopters affected by AD CF-2002-03R2. CASA, as Australia’s national airworthiness authority, evaluates such international directives and, if necessary, issues corresponding Australian ADs to enforce the required safety measures within the Australian jurisdiction. Notably, these ADs are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. While the ADs are issued under specific international obligations and in response to directives from the State of Design, they do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to enact regulations that are vital for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments as per section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are essential for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the aircraft type, must provide necessary information to ensure its airworthiness. The State of Registry, on the other hand, must develop or adopt requirements to maintain the airworthiness of individual aircraft. For example, when Transport Canada issued AD CF-2002-03R2 concerning Bell 427 helicopters, CASA assessed the information and issued Australian AD/BELL 427/3, which became effective on 11 May 2006.
The obligations imposed by the Civil Aviation Safety Regulations 1998 include CASA's responsibility to evaluate ADs issued by the State of Design and, if deemed necessary, issue corresponding ADs for the Australian Register. This ensures that the requirements set by the State of Design are adopted and enforced within Australia. Additionally, as these ADs are issued due to Australia's obligations under international conventions, they do not require public consultation or a Regulatory Impact Statement.
There are significant consequences for non-compliance with these airworthiness directives. Civil penalties may be imposed for breaches, and in severe cases, criminal penalties can apply. The maximum penalties are determined by the severity of the offence, with civil penalties often involving substantial fines and criminal penalties potentially including imprisonment. These provisions underscore the importance of adhering to ADs to maintain the safety and airworthiness of aircraft within Australia.
