IAE1J12105 is a precision-manufactured aerospace engine low-pressure turbine (LPT) vane retainer clip, compliant with AS9100D quality standards and FAA/EASA regulations, designed for IAE V2500 series turbofan engines. It secures the LPT stator vanes in the engine casing, maintaining the precise position and angle of each vane, which is critical for ensuring smooth, uniform exhaust gas flow through the turbine, optimizing the engine's exhaust energy utilization, and preventing vane displacement that may reduce engine thrust or cause vibration.

Made from high-strength, heat-resistant nickel-based superalloy, it withstands operating temperatures up to 920°C and continuous gas impact. Weighing 0.04kg 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.
