VKT-TJ-FDJ-2811/2563 is a specialized aviation ground support tool compliant with AS9100D standards and FAA/EASA regulations, engineered for the disassembly, assembly and torque calibration of turbofan engine core components during ground MRO operations. Forged from high-strength anti-corrosion alloy steel with heat-resistant plating, it withstands extreme temperatures from -55℃ to 260℃, resisting engine thermal stress and mechanical impact without deformation. Its precision-machined torque adapters and alignment pins ensure damage-free handling of critical engine parts, preventing misalignment risks that impair performance. Compact and ergonomic, it fits confined engine bays, streamlines maintenance workflows, cuts ground downtime, and serves as an indispensable tool for aircraft engine operational reliability and flight safety.
