856A1603G07 is a precision-engineered aerospace engine high-pressure compressor (HPC) variable stator vane, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 turbofan engines. It adjusts the angle of incoming air into the HPC stages based on the engine's operating state, optimizing air flow and compression efficiency across different thrust settings, which is critical for preventing compressor surge, ensuring stable air supply to the combustion chamber, and supporting consistent engine performance during takeoff, climb, cruise, and descent.

Made from high-strength, heat-resistant titanium alloy, it withstands operating temperatures up to 590°C and continuous air flow impact. Weighing 0.24kg with a precision-machined actuation interface, it enables fast adjustment and position verification during HPC MRO overhauls. FAA Part 25 certified, it is a key component for HPC performance and engine operational stability.
