98S71003000002 is a precision-manufactured aerospace engine fan blade retainer component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engines. It is a core fixing structure in the engine fan section, securing the fan blades on the fan hub, which is critical for preventing the fan blades from detaching during high-speed rotation, maintaining the stability of the fan's operation, and avoiding severe damage to the engine and aircraft caused by blade displacement.

Made from high-strength, corrosion-resistant titanium alloy, it withstands operating temperatures from -55°C to 210°C and intense centrifugal force during fan operation. Weighing 0.86kg with a precision-machined clamping structure, it allows for fast installation and clamping tightness inspection during fan section MRO overhauls. FAA Part 25 certified, it is a key component for engine fan section operational safety.
