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 French DGAC issued UF-2006-042, affecting Eurocopter AS365 model helicopters aircraft, in 2006. France is the State of Design for Eurocopter helicopters. As a result of a request from industry, CASA has amended the equivalent Australian AD to Amendment 1. The amended AD, AD/DAUPHIN/72 Amendment 1, will become effective on 13 April 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, 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, enacted by the Commonwealth Parliament, provides the legal framework for ensuring the safety and efficiency of civil aviation in Australia. The Act empowers the Governor-General to create regulations that serve the interests of air navigation safety. One significant aspect of this Act is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to mandate specific requirements for aircraft and aeronautical products to ensure their continuing airworthiness. The policy objective behind these regulations is to align Australian aviation safety standards with international conventions and to maintain a high level of safety in the Australian airspace. The ADs serve as a mechanism to address safety issues and ensure compliance with international obligations, particularly those under Annex 8 of the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve to ensure the continuing airworthiness of aircraft and are mandated by Australia’s obligations under the Convention on International Civil Aviation. The ADs apply to aircraft registered in Australia, and CASA is responsible for issuing corresponding Australian ADs when a State of Design issues an AD affecting a type of aircraft on the Australian Register. The geographic and jurisdictional reach of these regulations is national, as CASA acts on behalf of the Commonwealth of Australia. The ADs are legislative instruments under the Legislative Instruments Act 2003 and are subject to disallowance as per the Acts Interpretation Act 1901. Exemptions or exclusions from these ADs are not specified within the explanatory statement, and their application is extended through subordinate regulations, ensuring compliance with international standards.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations that safeguard air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. Under subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is thus classified as a legislative instrument as per section 6 of the Legislative Instruments Act 2003. This legal framework ensures that ADs are authoritative tools for maintaining the airworthiness of aircraft.
The obligations imposed by the Act and the accompanying regulations are substantial. The State of Design, in this case France for Eurocopter AS365 model helicopters, holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must furnish necessary information to States of Registry. The State of Registry, here represented by Australia through CASA, must then assess this information and, if necessary, issue corresponding ADs to enforce the requirements set by the State of Design. This collaborative regulatory approach is consistent with Annex 8 of the Convention on International Civil Aviation, which mandates that States of Registry develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within their jurisdiction.
Breach of the requirements stipulated in ADs can lead to significant legal consequences. While the specific penalties for non-compliance with ADs are not detailed in the provided text, general aviation regulations typically include both civil and criminal penalties for violations. Civil penalties may include fines, while criminal penalties can encompass imprisonment, reflecting the serious nature of non-compliance with aviation safety regulations. These consequences underscore the critical importance of adhering to ADs to maintain the highest standards of aviation safety.
The legislative process for issuing ADs, as outlined in the Act, involves thorough assessment and, where necessary, the amendment of existing directives. For instance, in response to the French DGAC’s UF-2006-042 directive, CASA has amended the corresponding Australian AD to Amendment 1, effective from 13 April 2006. This amendment cancels and replaces the previous AD, demonstrating the dynamic nature of airworthiness directives in response to evolving safety concerns. The issuance of such directives typically does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review, streamlining the process while maintaining stringent safety oversight.
