856A1519G01 is a precision-manufactured aerospace engine low-pressure turbine (LPT) mounting bracket, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines.It is a core load-bearing and positioning structure for the LPT, fixing the LPT assembly in the engine core's rear section, which is critical for maintaining the alignment of the LPT's rotor and stator components, reducing vibration during high-speed, high-temperature operation, and ensuring the LPT can efficiently convert the remaining exhaust gas energy into rotational power.

Made from high-strength, heat-resistant nickel-based superalloy, it withstands operating temperatures from -55°C to 890°C and long-term mechanical load. Weighing 1.34kg, it allows fast installation and structural stress testing during LPT MRO overhauls. FAA Part 25 certified, it is a key component for LPT operational stability.
