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.
Transport Canada has issued AD CF-2004-05R2 affecting Bell 206 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/153, Amendment 3, which will become effective on 27 October 2005. 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 provide a framework for the regulation of civil aviation in Australia, focusing on safety, efficiency, and environmental considerations. Under this Act, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed provisions for ensuring the safety of air navigation. One of the significant mechanisms within these regulations is the issuance of airworthiness directives (ADs). ADs are legislative instruments that mandate specific requirements for maintaining the airworthiness of aircraft and aeronautical products, thereby ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The Australian Civil Aviation Safety Authority (CASA) issues these directives to address safety concerns identified by the State of Design or in response to international safety notices. This regulatory approach allows Australia to meet its obligations under international aviation agreements while maintaining the safety of its aviation fleet. The ADs do not typically require public consultation as they are based on international obligations and assessments, and they are considered legislative instruments under the Legislative Instruments Act 2003.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for issuing airworthiness directives (ADs) in Australia, which are legislative instruments intended to ensure the safety of air navigation. The Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These directives are designed to address safety concerns and ensure compliance with international standards set by the Convention on International Civil Aviation. ADs are applicable to aircraft registered in Australia and are issued in response to directives from the aircraft's State of Design or in accordance with international obligations. The issuance of these directives does not require consultation with the public, and they are issued by CASA under the authority granted by the Act, with the Manager, Airframes in the Manufacturing, Certification and New Technologies Office playing a key role in their development and implementation.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives, detailed in subregulation 39.001(5), are legislative instruments, disallowable as per section 46A of the Acts Interpretation Act 1901, and must adhere to the Legislative Instruments Act 2003. This regulatory framework is essential for ensuring the continuing airworthiness of aircraft, a responsibility that the State of Design must uphold as per Annex 8 of the Convention on International Civil Aviation. The State of Design, such as Canada for the Bell 206 model helicopters, must provide necessary information to ensure the airworthiness of aircraft types, which CASA then assesses and, if necessary, mandates through Australian ADs.
The obligations imposed by this legislation are multifaceted. The State of Design must continually monitor and provide updates on the airworthiness of aircraft types, ensuring that any safety issues are promptly communicated. CASA, as Australia’s national airworthiness authority, must rigorously assess these directives to determine their applicability to aircraft on the Australian Register. Upon determining that an AD is necessary, CASA must issue a corresponding Australian AD to enforce the required safety measures. This process ensures that Australian-registered aircraft meet international safety standards.
Failure to comply with airworthiness directives can result in significant consequences. Non-compliance with an AD may lead to the grounding of an aircraft, as CASA has the authority to take enforcement actions against non-compliant aircraft. Furthermore, if an AD mandates specific maintenance or operational procedures, and these are not followed, it could result in serious safety incidents, potentially leading to criminal charges under the Civil Aviation Act 1988. Such charges could carry substantial penalties, reflecting the gravity of the safety implications. In addition to potential criminal penalties, airlines and aircraft operators may also face civil liability for damages resulting from accidents caused by non-compliance with airworthiness directives.
