856A4201G02 is a precision-engineered ground support fixture for aircraft engine fuel nozzle maintenance, compliant with AS9100D quality standards and FAA/EASA MRO regulations. Optimized for narrow-body turbofan engines like CFM56-5B/7 and V2500, it provides stable, calibrated positioning for nozzle disassembly, cleaning, flow testing, and spray pattern verification during overhauls, ensuring fuel atomization efficiency critical to engine combustion performance.

Crafted from high-strength alloy steel with anti-corrosion plating, it features adjustable non-marring clamping jaws, integrated fuel test ports, and a 360° rotating work platform. Its ergonomic height adjustment (0.8–1.6m) reduces technician fatigue. Weighing 240kg (1750×1150×950mm), it streamlines servicing workflows, minimizes component damage, and upholds post-maintenance engine airworthiness for commercial fleets.
