98D5440300400 is a precision aerospace maintenance tool, compliant with AS9100D aerospace quality standards and FAA/EASA regulations, designed for commercial aircraft engine fuel systems maintenance.

It functions as a specialized fuel line fitting torque wrench, used to tighten or loosen fuel line fittings during MRO work. It delivers precise, calibrated torque to avoid damaging fitting threads or sealing surfaces, preventing fuel leakage that would create fire hazards, disrupt fuel supply stability, or cause abnormal engine combustion that affects flight safety.

Made from heat-treated, high-strength alloy steel, it has a precision-machined head to match specific fuel line fitting sizes, and an ergonomic non-slip grip for comfortable operation. Weighing 0.76kg, it is portable for on-wing or hangar use, critical for fuel system maintenance reliability.
