856A2705G03 is a precision aerospace machining fixture, compliant with AS9100D quality standards and FAA/EASA regulations, designed for the maintenance of CFM56-5B aircraft engines.

It acts as a positioning fixture for the engine's high-pressure compressor seal ring, used to fix and align the seal ring during component machining and inspection in MRO processes. It ensures the seal ring maintains precise dimensional accuracy and positional alignment, which is essential for preventing compressed air leakage in the compressor, avoiding reduced engine compression efficiency, increased fuel consumption, or unstable power output during flight.

Made from high-strength, wear-resistant alloy steel, it resists deformation under machining pressure, and works stably at -40°C to 220°C. Weighing 0.68kg, it allows quick installation and removal, a critical tool for engine compressor maintenance accuracy.
