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 Civil Aviation Safety Authority or its predecessors issued AD/HU 269/74 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/74. The cancellation will become effective on 7 May 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the industry. One of the key mechanisms through which this is achieved is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Authority (CASA) has the authority to issue ADs for types of aircraft or aeronautical products to ensure the continuing airworthiness of aircraft. The Act and the Regulations were designed to align Australia's civil aviation safety standards with international obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. This convention places the responsibility of continuing airworthiness on the State of Design and the State of Registry, with CASA acting as Australia's national airworthiness authority. The policy objective is to maintain high safety standards in the aviation industry through the effective implementation of ADs, as demonstrated by the recent cancellation of AD/HU 269/74 for Schweizer (Hughes) 269 series Helicopters, reflecting Australia's commitment to international civil aviation standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. Under section 98 of the Act, the Governor-General has the authority to make regulations in the interests of air navigation safety, and regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The State of Design, typically the manufacturer's country, has the primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry, which in turn are responsible for the airworthiness of individual aircraft registered within their jurisdiction. CASA, as Australia's national airworthiness authority, must assess any ADs issued by a State of Design and, if appropriate, issue corresponding Australian ADs. This regulatory approach is consistent with Annex 8 to the Convention on International Civil Aviation, which mandates that States of Design and States of Registry collaborate to maintain airworthiness standards. In this context, the cancellation of Australian AD/HU 269/74 for Schweizer (Hughes) 269 series helicopters reflects Australia’s compliance with international obligations, with no requirement for public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework for aviation safety in Australia, enabling the Governor-General to issue regulations under section 98 for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, as defined under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs serve to communicate the continuing airworthiness requirements of aircraft types, aligning with Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for airworthiness to the State of Design.
Under these regulations, the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure compliance. The State of Registry, which is the country where the aircraft is registered, must then implement or adopt the requirements to ensure the aircraft's airworthiness. In the context of Australian-registered aircraft, CASA evaluates information from the State of Design and may issue Australian ADs to enforce the required safety measures. This ensures that Australian aircraft meet the continuing airworthiness standards stipulated by international conventions.
The obligations imposed on parties governed by these regulations include the timely assessment and implementation of ADs issued by CASA. Aircraft operators, owners, and maintenance organisations must comply with the ADs to ensure the safety and airworthiness of their aircraft. This compliance ensures that any identified unsafe conditions are rectified in accordance with the directives. CASA's role is pivotal in monitoring adherence to these regulations, ensuring that all Australian-registered aircraft meet the necessary safety standards.
Failure to comply with an airworthiness directive can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance can lead to both civil and criminal penalties. Civil penalties may include fines up to $165,294 for individuals and $826,470 for corporations, as stipulated under the relevant sections of the Act. Additionally, criminal penalties can apply, with individuals facing imprisonment for up to five years and corporations facing fines of up to $4.25 million. These stringent penalties underscore the importance of adhering to the airworthiness directives to maintain the highest safety standards in aviation.
