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.
CASA raised AD/ECURIEUIL/30 Amendment 1 to correct an unsafe situation on AS350 rotorcraft in March 2007. The Amendment 1 to the AD changed the applicability to clarify affected part numbers at the request of the industry. Unfortunately, Amendment 1 contained a typographical error in the related Service Bulletin number, so Amendment 2 has been raised to correct this. Amendment 2 will become effective on 7 June 2007, and cancels and replaces the previous amendment.
CASA has not consulted with the Australian industry and public, as the industry requested the change be made to the current 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 civil aviation in Australia, with a strong emphasis on safety and regulation. This Act empowers the Governor-General to make regulations that serve the interests of safe air navigation, a critical mandate underscored by its delegation to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are essential tools for ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by Annex 8 to the Convention on International Civil Aviation. The objective of this legislative framework is to maintain high safety standards in Australian civil aviation by enabling CASA to mandate corrective actions when necessary, as dictated by the State of Design or identified by CASA itself. This ensures that both the State of Design and the State of Registry adhere to their respective responsibilities under international conventions, thereby safeguarding the safety of air navigation within Australia.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, outlines the framework for the regulation of civil aviation safety in Australia. Under this legislative umbrella, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure their continuing airworthiness. These directives are issued to address identified safety issues and are legislative instruments under the Acts Interpretation Act 1901. The application of ADs is in line with international standards set by the International Civil Aviation Organization (ICAO), where the State of Design holds responsibility for the continuing airworthiness of aircraft types, and the State of Registry must ensure that the aircraft under its registry meet safety requirements. For Australia, CASA acts as the national airworthiness authority, assessing international directives and issuing corresponding Australian ADs as necessary. The scope of these regulations extends to all aircraft and aeronautical products registered in Australia, thereby impacting manufacturers, operators, and other relevant entities within the aviation industry. The geographic reach of these regulations is national, as they apply throughout Australia, and they do not include any specific exclusions or exemptions, although the necessity for ADs typically depends on identified safety concerns. Any changes or amendments to ADs are subject to review and are made by CASA, as demonstrated in the case of AD/ECURIEUIL/30 Amendment 1 and its subsequent Amendment 2, which corrected a typographical error to address an unsafe situation in AS350 rotorcraft.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance and enforcement of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These directives are considered legislative instruments as per subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions are significant. The State of Design, which is the country where the aircraft type was designed, has the primary responsibility for ensuring the continuing airworthiness of that aircraft type, including providing necessary information to other States of Registry. The State of Registry, where the individual aircraft is registered, must implement or adopt requirements to maintain the aircraft's airworthiness. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian registered aircraft meet international safety standards.
Failure to comply with ADs can result in serious legal consequences. The Civil Aviation Act 1988 does not explicitly state penalties for non-compliance with ADs, but non-compliance with airworthiness requirements can lead to significant civil and criminal penalties. Civil penalties can include fines up to the maximum specified by the regulations, while criminal penalties can include imprisonment, reflecting the high stakes involved in aircraft safety. Additionally, operators may face operational restrictions or be prohibited from flying non-compliant aircraft, which can have severe financial and operational consequences.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing and enforcing ADs to ensure the continuing airworthiness of aircraft. These provisions place significant responsibilities on States of Design and Registry, as well as on CASA, to maintain high safety standards. Non-compliance with ADs can lead to severe civil and criminal penalties, underscoring the importance of adhering to these directives.
