856A3712G01 is a precision-manufactured aerospace engine fan frame mounting bracket component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core load-bearing and fixing structure in the engine fan section, supporting and fixing the fan frame on the engine casing, which is critical for maintaining the position stability of the fan frame, reducing the vibration transmitted from the fan to the engine casing during operation, and ensuring the overall structural stability of the engine fan section.

Made from high-strength, lightweight aluminum alloy with anti-corrosion surface treatment, it withstands operating temperatures from -55°C to 200°C and continuous mechanical load. Weighing 1.12kg with a precision-machined connection interface, it allows for fast installation and structural stress inspection during fan section MRO overhauls. FAA Part 25 certified, it is a key component for engine fan section operational safety.
