856A1519G04 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 an optimized iteration of the 856A1519G01, acting as a core load-bearing and positioning structure for the LPT, fixing the LPT assembly in the engine core's rear section. It is critical for maintaining the precise alignment of LPT rotor and stator components, reducing vibration during high-speed, high-temperature operation, and improving the efficiency of converting residual exhaust gas energy into rotational power.

Made from a high-strength, heat-resistant nickel-based superalloy with enhanced anti-corrosion treatment, it withstands -55°C to 910°C operating temperatures and long-term mechanical load. Weighing 1.36kg, 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.
