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/BELL 206/12 affecting Bell 206 model aircraft.  CASA has assessed this AD and as a result has cancelled it.  The cancellation will become effective on 23 October 2008.  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, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.

Overview

The Civil Aviation Act 1988, enacted to ensure the safety and efficiency of civil aviation within Australia, provides the legislative framework within which the Civil Aviation Safety Regulations 1998 operate. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products, aligning with international standards under the Convention on International Civil Aviation. The ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 were introduced to address the need for stringent and consistent safety standards in civil aviation, ensuring that aircraft and aeronautical products meet the necessary safety requirements. CASA, as Australia’s national airworthiness authority, has the responsibility to issue and manage these directives, ensuring compliance with both national and international safety standards.

Scope and Application

The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under this Act, the Governor-General has the authority to create regulations that serve the interests of air navigation safety, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs concerning certain types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The ADs serve to ensure the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design must provide necessary information to the States of Registry. In Australia, CASA assumes the role of the national airworthiness authority and is responsible for assessing and potentially issuing Australian ADs when required by the State of Design. This process ensures that the safety standards are uniformly upheld across the Australian Register of aircraft. The issuance and cancellation of ADs, such as the recent cancellation of AD/BELL 206/12 for Bell 206 model aircraft, reflect Australia's commitment to international aviation safety standards while maintaining domestic airworthiness.

Key Provisions

The Civil Aviation Act 1988 provides the legislative framework for the regulation of civil aviation in Australia. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD, as defined under subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and thus a legislative instrument as per section 6 of the Legislative Instruments Act 2003. Under the obligations outlined in the Act and regulations, CASA must assess any AD issued by the State of Design for a type of aircraft on the Australian Register. If deemed necessary, CASA must issue an Australian AD to ensure the continuing airworthiness of the aircraft. This process is in line with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. In this context, the State of Registry, which for Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. In a specific instance, CASA issued AD/BELL 206/12 concerning Bell 206 model aircraft. After assessment, CASA determined that the unsafe condition addressed by the AD no longer existed, leading to the cancellation of the AD, effective 23 October 2008. No replacement AD was required. The cancellation was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, thus no public consultation was necessary. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The cancellation was authorised by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, under subsection 84A(2) of the Act. Breach of the provisions under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to various consequences. The Act and regulations mandate strict adherence to airworthiness requirements to ensure the safety of air navigation. Failure to comply with an AD or the regulations can result in serious civil or criminal penalties, including fines and imprisonment, depending on the severity and intent of the breach. The maximum penalties are specified within the Act and may be further detailed in associated regulations and guidelines issued by CASA.
