AD/RRT-S/4 Amdt 1 - H.P. Fuel Shut Off Valve Primary Strainer - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as the primary legislation governing civil aviation safety within Australia. This regulation, particularly the amendments detailed in PART 39 - 106, was introduced to address specific technical and safety concerns associated with aircraft engines, ensuring the continued airworthiness of aircraft operating within Australian airspace. One such amendment, AD/RRT-S/4, targets Rolls Royce Turbine Engines of the Spey Series, focusing on the High Pressure (H.P.) Fuel Shut Off Valve Primary Strainer. The objective of this amendment is to mandate inspections of these components to prevent operational failures and ensure the safety of aircraft utilising these engines. By doing so, the Civil Aviation Safety Authority aims to mitigate risks and maintain the highest standards of aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply to all individuals, entities, and industries engaged in civil aviation within Australia. Specifically, Part 39 - 106 of the Civil Aviation Regulations, which includes the Airworthiness Directives, governs the operational standards and maintenance requirements for aircraft and their components to ensure safety and airworthiness. The Rolls Royce Turbine Engines - Spey Series Airworthiness Directive AD/RRT-S/4 Amendment 1 pertains to Spey 511-8 engines equipped with high-pressure shut-off valves featuring Lucas SB LSB Sp 73-158, excluding those with high-pressure fuel pumps featuring LSB Sp 73-127 or LSB Sp 73-212. Compliance with the directive mandates the inspection of the H.P. fuel shut-off valve primary strainer as detailed in Rolls Royce Spey SB No. Sp 73-182. This directive applies nationally across Australia and is enforceable by the Civil Aviation Safety Authority (CASA). The regulations may be extended or restricted through subordinate instruments, ensuring ongoing compliance with safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, outlines the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, including the AD/RRT-S/4 amendment. This directive pertains to Rolls Royce Turbine Engines of the Spey Series, focusing on the High Pressure (H.P.) Fuel Shut Off Valve Primary Strainer. According to section 106 of the regulations, the directive applies to Spey 511-8 engines equipped with H.P. shut-off valves featuring Lucas SB LSB Sp 73-158 but not fitted with H.P. fuel pumps featuring either LSB Sp 73-127 or LSB Sp 73-212. The requirement is detailed in Rolls Royce Spey SB No. Sp 73-182, which outlines the necessary compliance steps for the inspection of the H.P. Fuel Shut Off Valve Primary Strainer. Under these regulations, the directive imposes specific obligations on the parties or entities governed by it. Operators and owners of Spey 511-8 engines fitting the criteria must ensure that the H.P. Fuel Shut Off Valve Primary Strainer is inspected as specified in Rolls Royce Spey SB No. Sp 73-182. This inspection must be conducted to verify that the primary strainer is free from damage, blockages, or any other conditions that could compromise the engine's operation. Additionally, it is necessary for the operators and owners to maintain accurate records of all inspections and any remedial actions taken in accordance with the directive. Failure to comply with the requirements set out in the AD/RRT-S/4 amendment may result in significant consequences. Section 106 of the Civil Aviation Regulations 1998 underscores the seriousness of non-compliance by stating that it could lead to penalties or other enforcement actions. Although the exact penalties are not detailed within the provided text, it is clear that the breach of these airworthiness directives can have serious implications for the safety and legality of operating the affected aircraft. Operators and owners who fail to adhere to the directive risk facing civil or criminal charges, depending on the severity and impact of the non-compliance.
