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 Italian ENAC has issued AD 2005-423 affecting Agusta A109 model helicopters. Italy is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A109/48, Amendment 1, which will become effective on 16 February 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 regulate civil aviation safety in Australia, aiming to ensure the safety of air navigation. It empowers the Governor-General to make regulations for the purposes of the Act, with a specific focus on maintaining the safety standards of air navigation. Complementing this, the Civil Aviation Safety Regulations 1998 establish frameworks for issuing airworthiness directives (ADs) for various kinds of aircraft or aeronautical products. These regulations were developed under the authority granted by section 98 of the Civil Aviation Act 1988, with the overarching goal of ensuring the continuing airworthiness of aircraft in line with international standards. The Civil Aviation Safety Authority (CASA) plays a pivotal role in implementing these regulations, assessing information from the State of Design, and issuing Australian ADs when necessary. The process of issuing such directives is governed by the requirement to align with Annex 8 of the Convention on International Civil Aviation, which assigns the responsibility of ensuring continuing airworthiness to the States of Design and Registry. This legislation thus forms a critical part of Australia's commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988 provides the legislative framework for civil aviation safety in Australia, and under section 98, the Governor-General may make regulations for the purposes of the Act, which includes the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the Act, include provisions for the issuance of airworthiness directives (ADs) for kinds of aircraft or aeronautical products by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments that mandate safety requirements for specific types of aircraft or aeronautical products to ensure their continuing airworthiness. The State of Design, in this case Italy for the Agusta A109 model helicopters, has the responsibility to issue ADs for aircraft types, while the State of Registry, in this case Australia for individual aircraft on the Australian Register, must implement these directives. CASA, as Australia's national airworthiness authority, assesses ADs issued by the State of Design and, if appropriate, issues Australian ADs to mandate the requirements. Given the international obligations under the Convention on International Civil Aviation, this process does not require public consultation or a Regulatory Impact Statement. The AD in question was issued by CASA on behalf of the Minister for Infrastructure and Transport, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations in the interest of air navigation safety, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. Subregulation 39.001(5) further specifies that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, classifying them as legislative instruments. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must furnish any necessary information to relevant States of Registry to facilitate this. ADs are the most prevalent method of disseminating such information among ICAO Contracting States. The State of Registry, on the other hand, bears the responsibility for the continuing airworthiness of individual aircraft and must implement or adopt requirements to maintain this airworthiness.
The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA, as Australia's national airworthiness authority, to evaluate any ADs issued by the State of Design for aircraft types registered in Australia. If deemed appropriate, CASA must issue a corresponding Australian AD to enforce the requirements set forth by the State of Design. This process was exemplified by the Italian ENAC's issuance of AD 2005-423 for Agusta A109 model helicopters, a type for which Italy is the State of Design. CASA has reviewed this AD and subsequently issued Australian AD/A109/48, Amendment 1, effective from 16 February 2006, which supersedes the previous directive.
Failure to comply with an AD can have significant legal consequences. Under the Civil Aviation Act 1988, any person who contravenes the provisions of an AD commits an offence and may be subject to penalties. The severity of these penalties can vary, but they are designed to ensure strict adherence to the mandated safety requirements. The specific penalties for breach of an AD are detailed within the relevant sections of the Civil Aviation Act 1988 and associated regulations, reflecting the critical importance of maintaining airworthiness standards to ensure the safety of air navigation. The legislative framework thus imposes stringent obligations and consequences to enforce compliance with airworthiness directives, reinforcing the paramount importance of safety in civil aviation.
