956A1617G01 is a precision-manufactured aerospace engine low-pressure turbine (LPT) stator vane retainer, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It fixes the LPT stator vanes in the engine casing, maintaining the precise angle and spacing of each vane, which is critical for guiding the exhaust gas to flow in the designed path, optimizing the energy conversion efficiency of the LPT, and avoiding vane displacement that may cause engine vibration, thrust loss, or increased fuel consumption.

Made from high-strength, heat-resistant nickel-based superalloy, it withstands operating temperatures up to 940°C and continuous scouring from high-speed exhaust gas. Weighing 0.07kg with a precision-locking structure, it allows for fast installation and position verification during LPT MRO overhauls. FAA Part 25 certified, it is a key component for LPT operational stability.
