AD/JBK 117/30 - Flight Controls - Fixed Bearing

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, was established to regulate civil aviation in Australia and ensure the safety of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act, with the overarching aim of safeguarding air navigation. Under this authority, the Civil Aviation Safety Regulations 1998 were introduced, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments to ensure the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The authority to issue such directives is exercised by CASA, which acts on behalf of Australia's obligations under international agreements and in response to directives issued by the relevant State of Design, as exemplified in the issuance of AD/JBK 117/30 in response to Japan's AD TCD-7358-2008.

Scope and Application

The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for airworthiness directives (ADs) under regulation 39.001, which empower the Civil Aviation Safety Authority (CASA) to issue these directives for specific types of aircraft or aeronautical products. These directives are legislative instruments subject to disallowance and are essential for ensuring the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design is responsible for the initial airworthiness, and the State of Registry must enforce these standards, with CASA playing a crucial role in Australia by issuing Australian ADs in response to directives from the State of Design. The AD TCD-7358-2008 issued by the Japan Civil Aviation Bureau for Kawasaki BK-117C-2 helicopters exemplifies this process, where CASA has issued AD/JBK 117/30 following their assessment of the Japanese directive. Given the international nature and obligations under the Convention, no public consultation is required for these directives, and they do not necessitate a Regulatory Impact Statement. The AD is issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the legislative provisions.

Key Provisions

The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are pivotal in understanding the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, as such, are considered legislative instruments in line with section 6 of the Legislative Instruments Act 2003. Annex 8 to the Convention on International Civil Aviation outlines that the State of Design bears overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry to maintain this airworthiness. The obligations and requirements imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are primarily focused on ensuring the safety and airworthiness of aircraft. The State of Design, in this case Japan for Kawasaki BK-117C-2 helicopters, must issue ADs if necessary to maintain the continuing airworthiness of the aircraft type. Upon receiving such an AD, CASA, as Australia’s national airworthiness authority, must evaluate the information and, if deemed necessary, issue an Australian AD to mandate the requirements of the State of Design. The State of Registry, which in this scenario would be Australia, is responsible for ensuring the continuing airworthiness of the aircraft and must implement the ADs issued by CASA. Failure to comply with ADs can result in serious consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences, penalties, or consequences for non-compliance with ADs. However, the overarching principle is that non-compliance with ADs can lead to serious safety risks, and CASA has the authority to take enforcement actions against non-compliant operators. These actions could include grounding the aircraft, imposing fines, or taking legal action. The safety implications of non-compliance can also extend to potential criminal charges under the Act if the non-compliance results in significant harm or loss of life. Given that ADs are issued under the auspices of international conventions and in response to ADs issued by the State of Design, there are no public consultation requirements for these instruments. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement, underscoring the urgency and critical nature of these directives. The AD is formally 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 Civil Aviation Act 1988, ensuring that the ADs are issued by authorised personnel within the regulatory framework.
