856A1868G03 is a precision-forged aerospace engine high-pressure turbine (HPT) retainer ring, compliant with AS9100D quality standards and FAA/EASA regulations, optimized for CFM56 and IAE V2500 turbofan engines. It fixes the HPT blade assembly on the turbine disk, preventing blade displacement or detachment when the turbine runs at high speeds (up to 15,500 RPM) in all flight phases, which is essential to avoid severe engine damage.

Made from a high-strength nickel-based superalloy with a thermal barrier coating, it can resist operating temperatures up to 940°C and extreme centrifugal forces. Weighing 1.15kg with a precision locking structure, it allows quick disassembly and installation during hot-section MRO overhauls. FAA Part 25 certified, it is a safety-critical component for HPT structural integrity and engine operational safety.
