AD/CT58/6 - Centrifugal Fuel Purifier

Overview

The Civil Aviation Regulations 1998, as amended, form a critical part of Australia's aviation safety framework. This legislative instrument, enacted by the Commonwealth of Australia, addresses the need for comprehensive regulations governing civil aviation operations, including the maintenance and airworthiness of aircraft components such as engines. Specifically, Part 39 - 106 pertains to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives. The policy objective of these regulations is to ensure that all civil aviation activities within Australian airspace meet stringent safety standards, thereby protecting the public and maintaining the integrity of the national aviation system. The regulations are designed to mandate compliance with safety directives issued by CASA, which include directives like AD/CT58/6 concerning General Electric CT58 series turbine engines, ensuring that these engines, when fitted with specific centrifugal fuel purifiers, meet safety standards and operational reliability.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, govern the airworthiness directives applicable to aircraft engines in Australia, including those manufactured by General Electric. The regulation pertains to all CT58 turbine engines equipped with centrifugal fuel purifiers and bearing serial numbers prior to 8493. The directive is designed to ensure the safety and compliance of these engines with established standards, mandating actions based on the General Electric Alert Service Bulletin No. (CT58) A73-62 (CEB 207) or AD/GE-T/15, and requires compliance before 31 December 1969. This regulation applies across the Commonwealth, ensuring uniformity in the enforcement of safety measures throughout Australia. The scope of the Act is limited to the specified engine models and serial numbers, and it does not explicitly mention any exclusions, exemptions, or thresholds within the provided text. The application of the directive can be extended or restricted through subordinate instruments, which provide additional specifications or clarifications to the main regulation.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, includes a Schedule of Airworthiness Directives that governs the maintenance and safety of aircraft engines. Among these, AD/CT58/6 pertains to General Electric Turbine Engines of the CT58 Series (sections 39-106). This directive applies to all CT58 engines equipped with a centrifugal fuel purifier with serial numbers prior to 8493. The directive is based on General Electric Alert Service Bulletin No. (CT58) A73-62 (CEB 207) or AD/GE-T/15, and compliance is required before 31 December 1969. This directive imposes specific obligations on the operators and maintainers of the affected engines. They must ensure that the centrifugal fuel purifiers in the CT58 engines are either replaced or modified as specified in the referenced service bulletins to prevent any potential safety hazards. This includes conducting a thorough inspection of the engine and fuel purifier, followed by the necessary modifications or replacements as outlined in the bulletins. Additionally, operators and maintainers must keep accurate records of all inspections, modifications, and replacements carried out on these engines to demonstrate compliance with the directive. Failure to comply with AD/CT58/6 can lead to significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against non-compliant operators and maintainers. This can include fines, enforcement notices, and in severe cases, the grounding of the affected aircraft until the required modifications are completed. The maximum penalties for non-compliance can be substantial, reflecting the critical nature of ensuring the airworthiness of these engines. Operators and maintainers must therefore take the directive seriously and ensure all requirements are met to avoid these potential penalties.
