AD/TFE 731/2 - Fuel Pump Anti-Icing Valve - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia's Parliament, is a comprehensive set of rules governing civil aviation safety within Australia. One specific legislative instrument within this broader regulatory framework is the AlliedSignal (Garrett/AiResearch) Turbine Engines - TFE731 Series AD/TFE731/2, which addresses safety concerns related to the inspection of fuel pump anti-icing valves in TFE-731-2-1C and -2-2B engines fitted with particular fuel control assemblies. This directive was introduced to mitigate risks associated with icing in the fuel pump anti-icing valves, ensuring the continued airworthiness of these engines. The objective of this directive is to maintain stringent safety standards within the aviation industry by mandating regular inspections of these components, thereby preventing potential failures that could compromise flight safety. This legislative instrument is part of the broader schedule of airworthiness directives issued by the Civil Aviation Safety Authority under Part 39 of the Civil Aviation Regulations 1998. Its purpose is to provide clear, enforceable requirements for the maintenance and operation of certain aircraft engines to ensure they meet the necessary safety standards. By referencing established safety bulletins and directives from entities such as AiResearch and the Federal Aviation Administration (FAA), the Australian regulations align with international best practices, ensuring a cohesive and effective approach to aviation safety both domestically and globally.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39, encompasses a range of safety directives and requirements aimed at ensuring the airworthiness of aircraft and related components. This particular legislative instrument, F2006B07402, pertains to AlliedSignal (Garrett/AiResearch) Turbine Engines of the TFE731 Series, focusing on the inspection of the fuel pump anti-icing valve. The regulation applies to aircraft equipped with TFE-731-2-1C and -2-2B engines fitted with certain fuel control assemblies, specifically P/No. 3070900-1 and 3070900-2. This directive mandates compliance within 100 hours of time in service following 27 February 1976, and references related safety bulletins or directives from AiResearch and the FAA, as well as AD/AIR-T/29. The geographic and jurisdictional reach of this legislation is national, applying to all civil aviation operations within Australia, as regulated by the Civil Aviation Safety Authority. There are no exclusions or exemptions explicitly stated in this directive, and its application extends to all relevant aircraft operators and maintenance providers under the oversight of the Civil Aviation Safety Authority.

Key Provisions

The key provision of the Civil Aviation Regulations 1998, specifically PART 39 - 106, mandates the adherence to Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). This includes the directive AD/TFE731/2, which pertains to the inspection of the fuel pump anti-icing valve on AlliedSignal (Garrett/AiResearch) Turbine Engines, specifically the TFE731 series (section 106). The directive applies to TFE-731-2-1C and -2-2B engines fitted with certain fuel control assemblies (section 106(3)). Under these regulations, the primary obligation for the parties governed by the Act is to comply with the AD within 100 hours of the engine's time in service after 27 February 1976 (section 106(3)). Compliance is to be achieved by following the specified documents: AiResearch SB TFE 731-73-3004, FAA AD No. 74-13-09, or AD/AIR-T/29 (section 106(4)). These documents provide detailed instructions and procedures necessary to ensure the safety and airworthiness of the engine. Failure to comply with the requirements set forth in the AD may result in significant legal consequences. While the specific penalties are not detailed within the text, non-compliance with airworthiness directives generally carries potential civil penalties under section 89 of the Civil Aviation Act 1988, which can include fines. Additionally, there may be criminal penalties if the non-compliance leads to an aviation accident or incident, as outlined in the criminal liability provisions of the Civil Aviation Act 1988. The seriousness of the offence and the specific penalties depend on the extent of the breach and its consequences.
