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 206/54 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 Technology 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 regulate and ensure the safety of air navigation, provides the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998. These ADs are essential for maintaining the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the Convention on International Civil Aviation. The act empowers CASA to mandate specific requirements to address unsafe conditions identified by the State of Design or Registry, thereby ensuring compliance with both national and international safety protocols. The ADs serve as legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. CASA's role in issuing and cancelling ADs, such as AD/BELL 206/54 for Bell 206 model aircraft, underscores the agency's commitment to safety and adherence to international obligations, as demonstrated by the recent cancellation of an AD due to the resolution of an unsafe condition.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, facilitates the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) for specified kinds of aircraft or aeronautical products to ensure the safety of air navigation. These directives are mandated under regulation 39.001 and are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thus qualifying as legislative instruments pursuant to the Legislative Instruments Act 2003. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, required to provide necessary information to the States of Registry as per Annex 8 of the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing this information and issuing corresponding ADs when required. The authority to issue these directives extends to ensuring compliance with international standards and addressing specific safety concerns, thereby maintaining the safety and airworthiness of aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988, in section 98, empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument, thus categorising it as a legislative instrument under section 6 of the Legislative Instruments Act 2003. ADs serve as a key mechanism for maintaining the continuing airworthiness of aircraft types, a responsibility that ultimately lies with the State of Design as per Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Act and its regulations are multi-faceted. Firstly, the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type, ensuring that this information reaches the appropriate States of Registry. Secondly, the State of Registry is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. For example, if a State of Design issues an AD concerning an aircraft type registered in Australia, CASA must assess this information and, if deemed necessary, issue an Australian AD to mandate the requirements of the State of Design.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to severe consequences. Although the specific offences and penalties are not detailed in the provided text, it is well-established that breaches of civil aviation regulations can result in substantial civil and criminal penalties. In general, the Act provides for various sanctions, including fines and imprisonment, depending on the severity and intent behind the breach. For instance, individuals or entities found in violation of ADs may face significant financial penalties and even imprisonment, underscoring the critical importance of adherence to these regulations.
Given the gravity of aviation safety, CASA's actions, such as issuing or cancelling ADs, are closely monitored and must align with international standards. The cancellation of AD/BELL 206/54 affecting Bell 206 model aircraft, for example, was made in accordance with Australia's obligations under the Convention on International Civil Aviation. This cancellation, effective from 23 October 2008, was executed without public consultation, as it was deemed unnecessary under the prevailing regulations. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, simplifying the process for CASA to issue or cancel such directives when necessary. The AD cancellation was made by the Manager, Systems and New Technology in the Airworthiness Engineering Group, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
