AD/CT58/3 - Combustion Casing Adapter Boss

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, represent a comprehensive framework designed to ensure the safety and efficiency of civil aviation operations within Australia. Among the various regulations, Part 39 - 106 specifically addresses the airworthiness directives, including the AD/CT58/3 which was introduced to address issues related to the General Electric Turbine Engines - CT58 Series. This directive, issued by the Civil Aviation Safety Authority (CASA), targets the combustion casing adapter boss for CT58-110-1 engines, referencing General Electric CEB documentation (CT 58) 72-81 and AD/GE-T/4. The policy objective of this directive is to enhance the structural integrity and safety of the affected engines, thereby mitigating potential risks associated with their operation. By issuing such directives, CASA aims to maintain high safety standards in the civil aviation sector, ensuring the reliability and performance of aircraft engines.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in Part 39 - 106 of the Civil Aviation Safety Authority's schedule of airworthiness directives, specifically target General Electric CT58 Series turbine engines, including the CT58-110-1 model, which are documented under General Electric CEB (CT 58) 72-81 or AD/GE-T/4. These regulations apply to all entities and persons operating or maintaining aircraft that are powered by these engines within the Commonwealth of Australia, ensuring that they comply with the specified airworthiness directives. The legislation mandates that these directives are mandatory and must be adhered to for the continued airworthiness of the affected aircraft. However, the regulations do not provide explicit exclusions or exemptions, implying that all applicable aircraft must meet the set safety standards without exception. The scope of the legislation is reinforced through subordinate instruments that may further detail or modify the application of these directives as necessary to address evolving safety concerns or operational contexts.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, Part 39 - 106, concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives for General Electric Turbine Engines - CT58 Series, specifically AD/CT58/3, focus on the requirement to address issues with the combustion casing adapter boss in CT58-110-1 engines (section 106.02). This airworthiness directive applies to all CT58-110-1 engines and mandates the implementation of specific corrective actions to ensure continued airworthiness and safety in accordance with the guidance provided in the General Electric CEB (CT 58) 72-81 or AD/GE-T/4 (section 106.03). The obligations imposed by this legislation on the parties or entities it governs are primarily concerned with ensuring that the corrective actions outlined in the referenced documents are properly carried out. Operators of CT58-110-1 engines are required to inspect and, if necessary, modify the combustion casing adapter boss to meet the specifications and safety standards set forth in the General Electric CEB (CT 58) 72-81 or AD/GE-T/4 (section 106.05). This includes documenting the inspection and any modifications made in accordance with the procedures specified in the referenced documents. Maintenance personnel must be properly trained and authorised to perform these tasks, ensuring that all actions are carried out to the required standard (section 106.06). Failure to comply with the provisions of this airworthiness directive can result in serious consequences. Civil penalties may be imposed for non-compliance, including fines and other monetary penalties (section 106.10). Additionally, operators found in breach of the airworthiness directive may face further regulatory action, including the potential grounding of non-compliant aircraft until the required corrective actions are completed (section 106.11). In severe cases, criminal charges may be brought against individuals or entities responsible for the non-compliance, leading to imprisonment and significant fines (section 106.12). The exact penalties depend on the nature and severity of the breach, but the regulatory body is empowered to impose the maximum penalties permitted by law to ensure compliance and uphold safety standards (section 106.13).
