AD/BELL 47/79 Amdt 1 - Tail Rotor Gearbox - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, ensuring safety and efficiency within the industry. This legislation, overseen by the Parliament of Australia, seeks to provide comprehensive regulatory frameworks that address various aspects of civil aviation, including airworthiness directives (ADs) to maintain the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, thereby ensuring compliance with international standards set forth by the Convention on International Civil Aviation. The policy objective underpinning these regulations is to safeguard the public by maintaining the highest possible safety standards in civil aviation, reflecting Australia's commitment to international aviation safety protocols.

Scope and Application

The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives apply to specific types of aircraft or aeronautical products, aiming to maintain their airworthiness. The scope of these directives is set out under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which empowers CASA to issue ADs for specified aircraft types. This regulation ensures that such directives are enforceable and form part of the legislative instruments as outlined in the Legislative Instruments Act 2003. The ADs are consistent with Annex 8 of the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and State of Registry. In this case, the AD/BELL 47/79 Amendment 1, issued by CASA, has been cancelled due to Australia’s obligations under the Convention, and this cancellation does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.

Key Provisions

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for issuing airworthiness directives (ADs). Specifically, section 98 of the Act allows the Governor-General to create regulations that serve the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for specific types of aircraft or aeronautical products. Notably, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby establishing them as legislative instruments in their own right. Under these provisions, CASA, acting within the framework provided by the Act and Regulations, has the responsibility to issue ADs to ensure the continuing airworthiness of aircraft. The State of Design, as per Annex 8 of the Convention on International Civil Aviation, has the overarching responsibility for the ongoing airworthiness of aircraft types and must supply necessary information to the State of Registry. Meanwhile, the State of Registry, which in this context is Australia, must implement or adopt requirements to maintain the airworthiness of individual aircraft. This dual responsibility ensures that both the design and the registry of aircraft are accountable for maintaining safety standards. The obligations imposed by these provisions require CASA to issue ADs to address safety issues identified with specific types of aircraft or aeronautical products. These directives must be based on the need to ensure airworthiness and must comply with international standards set by the Convention on International Civil Aviation. In the case of the Bell 47 model aircraft, CASA issued AD/BELL 47/79 Amendment 1, which has now been cancelled due to Australia’s obligations under the Convention. The cancellation of this AD, effective from 12 February 2009, signifies the conclusion of the regulatory oversight for this specific aircraft model within Australian jurisdiction. In terms of consequences for non-compliance, the Civil Aviation Act 1988 and associated regulations impose strict penalties for breaches of airworthiness requirements. The severity of penalties can range from fines to imprisonment, depending on the nature and extent of the violation. For instance, failing to comply with an AD could result in significant civil or criminal penalties, including substantial fines and potential imprisonment. The exact penalties are not detailed in the provided text but typically reflect the gravity of the breach and its impact on aviation safety.
