VKT-TJ-FDJ-EC17 is a specialized aviation ground support tool, engineered to AS9100D standards and FAA/EASA MRO regulations, dedicated to the maintenance of turbofan engine core components for narrow-body aircraft fleets. It functions as a precision torque wrench adapter, enabling calibrated, uniform torque application during the installation and removal of critical engine fasteners—including compressor rotor bolts and turbine casing clamps—thus preventing over-tightening damage or under-tightening safety risks.

Crafted from high-strength chrome-molybdenum steel with a corrosion-resistant finish, it operates reliably across -20°C to 50°C, features a modular design for compatibility with multiple torque wrench models, and weighs 1.2kg for easy handling. FAA Part 25 compliant, it is an indispensable tool for ensuring engine assembly integrity during MRO overhauls.
