956A1620G01 is a precision-manufactured aerospace engine high-pressure compressor (HPC) rotor balance weight, compliant with AS9100D quality standards and FAA/EASA regulations, designed for CFM56 series turbofan engines. It is mounted on the HPC rotor to adjust the rotor's mass distribution, eliminating dynamic imbalance that would cause high-amplitude vibration during high-speed rotation, which is critical for reducing wear of HPC bearings and components, avoiding structural fatigue damage, and ensuring the stable operation of the entire engine.

Made from high-density, high-strength tungsten-nickel alloy, it has a high mass-to-volume ratio to minimize installation space occupation. Weighing 0.22kg with a precision-threaded mounting structure, it allows for fast adjustment and balance verification during HPC MRO overhauls. FAA Part 25 certified, it is a key component for HPC operational stability.
